For 2 meter comms you could find an older Kenwood VHF LTR radio from the early 2000's. They are becoming more available on the used market at a reasonable cost. Avoid the UHF versions as they will not go into the ham bands. Make sure you purchase a low power unit since the high power has a longer heat sink and weighs a bit more. Radios program with radio software KPG- 49 as well as needing a rib box. There is info out there as to how to make the rib box.
Suggestion. For that particular kind of setup... I would change the pigtail to an SAE connector, with a standard blade fuse. These SAE connectors are super common in automotive use and would be easy to scavenge in a pinch. Also... During zombie apocalypse you could go steal a handful of fuses out of a car a lot quicker than trying to find those glass fuses. Your could additionally add to your kit, a SAE alligator clip adapter. In case you just wanted to quickly clip on a car battery.

Nice light portable setup. Those Abbree tactical antenna are very useful. Have one and I've tried making contact 74 km away just using my vintage IC-02AT at only 4 watts me being almost 200 feet above sea level.
Also, they sell small antenna extenders (I think that’s what they are called) that go between your antenna and your radio so you could just keep the antenna in the back of the bag, like you had it when it was in storage mode. Just a thought, that would possibly make it easier for fast deployment.
Thats cool.. Kinda funny, i was JUST looking on amazon for molle bags or pouches like this.. I also saw someone using a molle hydration pack as a manpack bag... it ended up working perfectly for his radio.
I got a few other bags, but this is the one I wanted for this project. Other packs to look into would be IFAK - individual first aid kit bags or some of the smaller bags from 511 or Maxpedition
That's awesome, I did a similar thing with a IC-2730A and a Gigaparts Tactical Sling bag. Even built my own battery with some 32700's on that one. All with the intention of using it for sats at some point.
Couple suggestion: 1 run the power cable and fuse into the battery compartment, making battery swaps easier. 1 get an rj45 right angle pigtail. I think the link I shared got my comment deleted but the brand name is Togcon Cat 6 Ethernet Extension Cable 5 Pack，Multiple Angles
You're already storing the antenna on the back of the bag when not in use. Turn your 90deg antenna connector towards the bottom of the radio. With a hole punched out the back of the pack you don't have to take off the antenna every time.
Reminds me of the scene in Steven Spielberg' 1941 . When the crew of the U- Boat Kidnap Slim Pickens And his radio . One Japanese Sailor, While trying to get the radio through the hatch of the Submarine. Makes the comment " We have to think of a way to make these Smaller"
@@temporarilyoffline I keep one in my truck (SMA) and one in my hiking bag as you can never know when you might need a backup antenna. I'll have to grab a BNC one. One of these days I need to figure out how to find the actual effectiveness of the antenna that is woven through the molle in my armor plate carrier. Those types of tests are beyond my current skills, but should be a great learning experience.
Rumor is there will, one day, be a transceiver which allows voice/analog which will include a a built in battery and transmit on both 2M and 70CM. Marketing department wants to call it a Handheld Transceiver, but R&D has already started nicknaming it HT, and after 5pm on Friday they started calling them Handy Talkies. All kidding aside, I like your videos.
I would dig a 50w HT! Would need a speaker mic though, and I bet it would get hot, so I'd want a fan and some kind of bag to put it in too. I can't wait for this thing to come out!
@@temporarilyoffline Yeah, the 50w feature is the current blocker in the sprint backlog. R&D test engineers have been taking an unjustified number of sick days alleging RF burns during testing. The execs know the engineers are just trying to cover up their lunch time fork-in-the-outlet competition injuries when the betting gets out of hand.

@@Maker_Mikey I've been fired by better over worse... my HR record is long and distinguished. No run dead test yet, trying to think of an actual use case... in the mean time I did some maths thing: th-cam.com/video/_P2vvo0y05Y/w-d-xo.htmlsi=E32aV68f3_iNIRbg
Great work. I have had great luck with the Digirig Lite in similar configurations (and micro USB to usbc adapters can be had on amazon). Might clean up the spaghetti a bit. :)
Like most similar radios, it's less than optimum for energy efficiency (battery life) It's rated at 350 milliamps receive when fully squelched. The FT-60 uses less than 50 ma squelched. They can do better.
Hey Steve! This is an awesome how to video and I'm glad I came across it! I'm going to build a similar pack for GMRS users and make a video about it also. There are a ton of new GMRS users getting involved and I haven't seen any packs built like this, and I would like to share your knowledge!
@mattburke3095 I have not yet. We are still helping with disaster relief in GA and SC from Hurricane Helene. I will be headed back home soon, and it will be done in December. I've gotten a lot if ideas on videos since I've been here, so it will be an active couple months coming up!
@temporarilyoffline I absolutely will! Your channel and this video will definately be mentioned and linked. Once I get back home and start, I may reach out to you for a couple ideas I have on the kit. Thank you sir!
My question: How much heat would that radio put out? I noticed a internal fan and you have not made a comment on it. (Old RadioMan, from U.S. Navy) My suggestion is to turn that radio around where the fan is pointed out the back side, and then make vent holes in the bag for better airflow. Yes you will lose some bag mollie points on the back, but, if the radio can not "breathe," then the radio will cook itself to an unusable shape. (And if it is like some radios, you could be carrying around a forest fire in that bag, if it got too hot! Most Forest Rangers would not look favorably on such, if it were to catch itself on fire from poor ventalation.)
Hello Jeffrey, Yeah, heat is a problem with any radio and its up to the operator to operate appropriately for the conditions at hand, even if it was your hands that made those conditions. My 818 and my G90 run hot sitting in an air conditioned shack. If I'm going to do extended high duty cycle ops, I'd take it out of the bag, add AC or a fan and complete the mission
@@temporarilyoffline So, you would have to sacrifice some portability for an extended use of this radio. (No objections, just observations.) As an old Radioman (U.S. Navy, and U.S. Army Reserves commo.) I can understand this, and have had the same problems with larger, (MUCH LARGER!) backpack radios. I am well out of that job, but, and as a suggestion for your concideration, why not remove the fan, and replace with a plenum box. Then have a separate cooling box to attach to the bottom of the pack? With it's own power supply, and tubing for cooled air to the radio? A little bit more to pack, but, when not using the radio, could be used as a personal cooling pack for you. Note: With a plenum box, you could direct cooled air to the hottest parts of the insides of your radio, and, maybe, extend the life of the radio.
Oh, BTW, this would be for an emergency situation. I wouldn't think that for short use (of a few minutes) of the radio it would be a problem. But, in an emergency, where the radio would be in constant use, a dedicated cooling fixture would be nice.
@@jeffreyharville1918 Yeah, for constant use you'd need something else for sure. Bigger battery, better cooling, better operation position/conditions maybe some snacks... this was primarily for walking around a park or hamfest with friends and playing radio. All those "little guys" with their "little HTs" and me with my 50 watter showin' 'em up!
I sorta love the design, but I would be worried about heat and where the vents are venting heat to. For extended use, it may have to come out of the little pack.
"Pretty slick," indeed! I'm just a little concerned about that heat sink on the bottom of the radio. Can it get hot enough to melt the fabric, or cause other problems in that tight space with all the plastic components? MOLLE pouches come in a huge variety of shapes and sizes. If you do some shopping, you should be able to find one with a bit more space. Or you can attach a smaller one to the font using the MOLLE webbing on this one. Having a separate removable pouch for the digital gear is a great idea.
You would be better of making a piggytail 90 ° uhf to bnc out of a coax,more flexible ,les lost and more forgiving,plus it would fit better.Nice little set up btw, i love that.
Question from a complete newbie: What's the use case for something like this? TH-cam chose to recommend this to me and I watched it going 'Cool...no idea what this is for'. Fun video regardless and I liked your dedication for getting everything to fit in a nice pack!
Glad you enjoyed the video. This radio is capable of person to person communication in a ~7mi radius. It can work through repeaters up to about ~30mi, and with the right conditions can pass traffic via APRS or Winlink all around the world (relay), even through the international space station (direct)
These man packs always look cool. My main concern is cable management and overheating the radios. Might be a good idea to make some sort of ventalation, or is that not a concern with these?
They are a good way to do short term comms - APRS RX and beaconing is fine in the bag... maybe a single winlink email TX. Long duration TX would go back to operator skill... to take it out of the bag. Honestly, the most important part of the bag is to have everything you need for your "mission" kept together.
@@temporarilyoffline I think that considering the radio has a fan on it, thats a decent indicator that it wont work well in an enclosed environment. If I were making a manpack with this radio in it, at the very least, I think I would 3d print a duct so the fan can pull in cold air from outside the pack, perhaps an exhaust also. If you wanted to get really nerdy and keep everything in the pack, you could likely cut a section out of the bottom of the pack, and place a heatsink on the outside of the pack, and screw it to the heatsink on the radio, a bit of thermal paste to join the two, and you would have the heatsink doing its job again
@@temporarilyoffline well, I have come to conclusion that manpacks etc arent something that im going to be using, I live where there arent any winlink nodes etc, no meshtastic available, so really most of what I can hear is on 14mhz and lower. I was in the process of making a portable system in a toolbox with batteries etc, but in reality i can just pop some crocodile clips onto the car battery and make do like that. Ive put extensive thought into it for a SHTF scenario, and the result of the thought is that I dont know anyone else that I care about who would be in communcation via ham radio. So handhelds for local use and an HF rig for long range info gathering are where its at. weather forecasts and news bulletins for ships are a good source of info etc. If you actually want to use that yeasu rig in a pouch, I would guess that the fan is blowing directly onto the final transistor like it is in other yeasu models I have, so you need ot be careful it wouldnt ever suck water or too much conductive dust in, I would say a duct with a dust cover, and a drain hole for incase water snuck in would work. You could likely forget the exhaust if you externalise the heatsink. to externalise the heatsink, I would file the back side of it flat, then hunt a suitable heatsink to bolt to it, and use a thermal pad instead of paste, because hand filing flat wont result in a flat enough surface for paste to be of use, a thermal pad will deform and join the two heatsinks nicely.
Another option since you’re not using the little pouch, make another pass-through and put all your digital stuff in the little pouch and then you’d only have the power cord and the digital cord coming out of it
What if you mounted the antenna on the outside of the pack and it is supported by the molly? Like make a small hole out the back of the pack. That way, you could fish the antenna up in the molly for a little protection.
I am looking for more information on this post there. Build this all together and work radio bag how do you get the radio to work on a battery pack and what kind of radio is it
This is a Yaesu FT-90. To get it to work on a battery, find a battery that is 12v output and make a connector to attach the battery to the radio. I use Anderson PowerPole connectors. Most radios operators have standardized on those for 12v operations. I have a video on making those on the channel as well. Let me know if you have any other questions.
I'd find someone to 3d print you a bracket to attach the antenna to the body of the antenna so there is less sway and cause stress on the antenna connectors.
Did this with a Kenwood 800 MHz trunking xceiver about 25 years ago. Dropped everything into a Radio Shack CD player shoulder pack, worked real good! Used a NiMh battery pack with the radio tuned to low power at about 5 watts. Very convenient for portable ops. Out preformed an 800 MHz HT. Checked the link for the antenna but it only lists the soft j-poles, nothing like the folding mail style antenna. Any other links to another site?
I actually just made one in battery math: th-cam.com/video/_P2vvo0y05Y/w-d-xo.html should help make the decision... But I've never gotten a battery and not found abuse for it. In this config I'm using a 3ah battery. It will last long enough for my use case. But maybe you'll need something bigger? The video will help with some of the math. But after that, the real world is the real test!
Awsome setup! But do handheld antennas and radios like this even work together really? When I tried something simmilar with a CB radio the performance was quite sh** to be honest.
@@temporarilyoffline I tried a folding antenna from the same brand but for CB and a telescopic one that is even longer but I heard that those antennas only really work well on handheld devices because the person holding it gives it some sort of ground. Sorry, I'm pretty much a noob and also not a native speaker 😂
So my question on this build: how much of a difference would you see if instead of the Abbree you use a Signal Stick? I have not looked at the Abbree, is it going to do a lot better?
That's a good question and pretty hard to measure. The Abbree is an EFHW, so "more wire in the air", but there is the transformer at the bottom. The Signal Stick is a 1/4wave and no transformer. Both are "resonant". I made an assumption and now you've got me wanting to testing that out.
Total newbie here. Please excuse the basic nature of the question, but to what purpose is the digital aspect of the setup? Can you either through the Pi or through a separate PC or phone use this for network access? Thanks in advance. Love the rig. If you were not going to use the external pocket, wouldn't the Pi 4 fit?
You can send digital communications through the radio other radios using the raspberry pi computer and your cell phone as a "keyboard/screen/mouse" or use it "at home" with a real computer setup. In part 2, I show how some of this works: th-cam.com/video/FECIfApYFjE/w-d-xo.html Check it out!
Every radio has an issue with overheating. A good operator takes that into consideration. I have some radios that I have installed fans into and Yaesu has had problems with the 817 burning out finals in "good" operating conditions. Just gotta be on your toes!
I know I have asked a couple times, but would you please share again, what the mini screwdriver and the soldering iron is that you are using. I know you didnt use the mini electric screwdriver this time, but you and Jim tend to love that little electric thing, and I cant recall what it is.
That looks like a "Pinecil" soldering iron. Uses readily available TS100 tips. If you take the tip out it packs down tiny and plugs into USB PD or barrel jack. Great for home bench or field use. Lots of settings and controls on board.
@chrisrobinsonkf6nfw TH-cam might not have sent you the notification, but I dropped some links in this thread for you. Let me know if you don't see them.
How long do you think the 3ah battery will last? The reason I ask. I have a similar setup like this with a 40watt mobile that I take to the hunting camp and have it hooked up to a solar system but would love to take the hunting house. Thank you for videos and advise
As with anything in ham radio "it depends" - at a hamfest, I'd expect I wouldn't get a full day out of it with everybody beaconing APRS in range and making me re-transmit. The Pi running full stop is a factor. More testing is needed. I'm not sure how to make a video out of it though... have to find a way to force an "average use case"
@@temporarilyoffline thank you sir. My use case would be 25% duty cycle. At most. Transmitting 25% receiving 75%. Usuing just voice fm. I have mine setup in a sar pack. I just take it with me hunting
Nice build! I could see something like this working as a way to carry around something like a Radioddity DB25-D (their little mini DMR mobile), so you could get both analog and digital voice in the pack (as well as packet). Question: What's the power rating on that Abbree? Or in other words, were you running 50 watts thru that thing right next to your body?
Its rated at 20w and I live on the edge... I was TXing very briefly close to my personage. - I've got a DB25 inbound and a full on kit with a hotspot would be pretty doable. I'll know soon.
@@temporarilyoffline just kidding of course, i love what you do and how you present present great amount of info easy enough for a new ham, but keep it fun as well. Ive learned a lot, keep em coming! VE6APN
Looks like you got part 3 first... part 2 is where I got it working with a DigiRig, DigiPi and did some APRS (which means it will also do winlink). Check it out here: th-cam.com/video/FECIfApYFjE/w-d-xo.html
The right angle UHF SO239 adapters and the UHF SO239 connector at the back of the radio does not allow an exact 90 degree connection. All radios with the UHF SO239 connector seem to have the same problem. They have all been machined incorrectly! I have never seen a UHF SO239 connector or adapter which permits an exact 90 degree connection so the antenna is at 90 degrees to the radio, which is obvious with yours as well. The 90 degree connector will ALWAYS be about 1 degree out at the connector which means any antenna will be obviously crooked by a considerable amount at the tip, as is yours!
I found this bag from gigaparts works really well for the 818: www.gigaparts.com/green-tactical-sling-bag.html use code KM9G at checkout for some savings!
Do not under any circumstances run the FT-90 inside a closed pack. It'd be the last time you do as you'll fry it. Half unzipped won't help much. That fan needs to run on high.
These are especially sensitive to heat. Also look up the squelch issues you will likely encounter as the radio gets a lot of use, along with the channel spacing setting.
Hate to break it to you… there’s an even smaller radio. The Anysecu WP-9900, if you can get Amazon to send you the right one. Plus all the controls and screen are on the speakermic.

That's awesome, I did a similar thing with a IC-2730A and a Gigaparts Tactical Sling bag. Even built my own battery with some 32700's on that one. All with the intention of using it for sats at some point.
There's always tomorrow! I just keep telling myself that
Couple suggestion: 1 run the power cable and fuse into the battery compartment, making battery swaps easier. 1 get an rj45 right angle pigtail. I think the link I shared got my comment deleted but the brand name is Togcon Cat 6 Ethernet Extension Cable 5 Pack，Multiple Angles
Good ideas, thanks! Yeah, TH-cam doesn't allow links in comments
You're already storing the antenna on the back of the bag when not in use. Turn your 90deg antenna connector towards the bottom of the radio. With a hole punched out the back of the pack you don't have to take off the antenna every time.
Good idea!
Would love to see the same kind of kit, but in an HF version (with a trusdx maybe to keep it tiny?). Cheers!
I don't have a trusdx anymore, but I have a video planned for the uSDX and for the FT-818 in a smaller bag than my current get-up. Stay tuned!

Very cool! I didn't know ABBREE made BNC antennas. Love that. Thanks for another great video Steve.
Hey Paul! I've had this one for a while now. They make a lot of antennas and at first I thought they were a gimmick, but they work well.
@@temporarilyoffline I keep one in my truck (SMA) and one in my hiking bag as you can never know when you might need a backup antenna. I'll have to grab a BNC one. One of these days I need to figure out how to find the actual effectiveness of the antenna that is woven through the molle in my armor plate carrier. Those types of tests are beyond my current skills, but should be a great learning experience.
@@NovemberOneOscarGrouch hit me up on discord, I've got some ideas

Rumor is there will, one day, be a transceiver which allows voice/analog which will include a a built in battery and transmit on both 2M and 70CM. Marketing department wants to call it a Handheld Transceiver, but R&D has already started nicknaming it HT, and after 5pm on Friday they started calling them Handy Talkies.
All kidding aside, I like your videos.
I would dig a 50w HT! Would need a speaker mic though, and I bet it would get hot, so I'd want a fan and some kind of bag to put it in too. I can't wait for this thing to come out!
@@temporarilyoffline Yeah, the 50w feature is the current blocker in the sprint backlog. R&D test engineers have been taking an unjustified number of sick days alleging RF burns during testing. The execs know the engineers are just trying to cover up their lunch time fork-in-the-outlet competition injuries when the betting gets out of hand.

Melting the bag it could still fray, you might use a grommet like the ones used on the belt for a safety harness.
Good idea, thanks!
Like most similar radios, it's less than optimum for energy efficiency (battery life) It's rated at 350 milliamps receive when fully squelched. The FT-60 uses less than 50 ma squelched. They can do better.
yeah, its "mobile" vs "portable" - in the mobile env, the maker is expecting an alternator and a BA battery.
Hey Steve! This is an awesome how to video and I'm glad I came across it! I'm going to build a similar pack for GMRS users and make a video about it also. There are a ton of new GMRS users getting involved and I haven't seen any packs built like this, and I would like to share your knowledge!

Internally route your excess cabling into the small pouch at the top!
Good idea
FIRST! I could only find these way over what you paid for yours. Cool little radio!
Gotta have a head on a swivel at a hamfest.
Pretty cool little set up. Thanks for sharing.
Thanks for watching!
My question: How much heat would that radio put out? I noticed a internal fan and you have not made a comment on it. (Old RadioMan, from U.S. Navy) My suggestion is to turn that radio around where the fan is pointed out the back side, and then make vent holes in the bag for better airflow. Yes you will lose some bag mollie points on the back, but, if the radio can not "breathe," then the radio will cook itself to an unusable shape. (And if it is like some radios, you could be carrying around a forest fire in that bag, if it got too hot! Most Forest Rangers would not look favorably on such, if it were to catch itself on fire from poor ventalation.)
Hello Jeffrey, Yeah, heat is a problem with any radio and its up to the operator to operate appropriately for the conditions at hand, even if it was your hands that made those conditions. My 818 and my G90 run hot sitting in an air conditioned shack. If I'm going to do extended high duty cycle ops, I'd take it out of the bag, add AC or a fan and complete the mission
@@temporarilyoffline So, you would have to sacrifice some portability for an extended use of this radio. (No objections, just observations.) As an old Radioman (U.S. Navy, and U.S. Army Reserves commo.) I can understand this, and have had the same problems with larger, (MUCH LARGER!) backpack radios. I am well out of that job, but, and as a suggestion for your concideration, why not remove the fan, and replace with a plenum box. Then have a separate cooling box to attach to the bottom of the pack? With it's own power supply, and tubing for cooled air to the radio? A little bit more to pack, but, when not using the radio, could be used as a personal cooling pack for you. Note: With a plenum box, you could direct cooled air to the hottest parts of the insides of your radio, and, maybe, extend the life of the radio.
Oh, BTW, this would be for an emergency situation. I wouldn't think that for short use (of a few minutes) of the radio it would be a problem. But, in an emergency, where the radio would be in constant use, a dedicated cooling fixture would be nice.
@@jeffreyharville1918 I have other boxes for other purposes - as you know, there is no 1 perfect go-box. Nobody could carry it!
@@jeffreyharville1918 Yeah, for constant use you'd need something else for sure. Bigger battery, better cooling, better operation position/conditions maybe some snacks... this was primarily for walking around a park or hamfest with friends and playing radio. All those "little guys" with their "little HTs" and me with my 50 watter showin' 'em up!
Very cool. My creative juices are beginning to flow. 😎
Nice! I saw someone at the gas station today with the bag on her belt. I smiled.
I sorta love the design, but I would be worried about heat and where the vents are venting heat to. For extended use, it may have to come out of the little pack.
I want to find a way to tame the cable mess, but yeah... I'd be watching out for heat.
"Pretty slick," indeed! I'm just a little concerned about that heat sink on the bottom of the radio. Can it get hot enough to melt the fabric, or cause other problems in that tight space with all the plastic components?
MOLLE pouches come in a huge variety of shapes and sizes. If you do some shopping, you should be able to find one with a bit more space. Or you can attach a smaller one to the font using the MOLLE webbing on this one. Having a separate removable pouch for the digital gear is a great idea.
If you're really choochin on the radio, you should take it out of the bag - would save both the radio and the bag.
Might try to add clip on counterpoise wire to improve range.
ooh a Tiger Tail!
You would be better of making a piggytail 90 ° uhf to bnc out of a coax,more flexible ,les lost and more forgiving,plus it would fit better.Nice little set up btw, i love that.
Thanks for the tip
Now I need an FT-90R!
N+1
Question from a complete newbie:
What's the use case for something like this?
TH-cam chose to recommend this to me and I watched it going 'Cool...no idea what this is for'. Fun video regardless and I liked your dedication for getting everything to fit in a nice pack!
Glad you enjoyed the video. This radio is capable of person to person communication in a ~7mi radius. It can work through repeaters up to about ~30mi, and with the right conditions can pass traffic via APRS or Winlink all around the world (relay), even through the international space station (direct)
You could get a radio strap that's meant to hold a lapel mic on your chest if you're on the go..
Good idea!
These man packs always look cool. My main concern is cable management and overheating the radios. Might be a good idea to make some sort of ventalation, or is that not a concern with these?
They are a good way to do short term comms - APRS RX and beaconing is fine in the bag... maybe a single winlink email TX. Long duration TX would go back to operator skill... to take it out of the bag. Honestly, the most important part of the bag is to have everything you need for your "mission" kept together.
@@temporarilyoffline I think that considering the radio has a fan on it, thats a decent indicator that it wont work well in an enclosed environment. If I were making a manpack with this radio in it, at the very least, I think I would 3d print a duct so the fan can pull in cold air from outside the pack, perhaps an exhaust also.
If you wanted to get really nerdy and keep everything in the pack, you could likely cut a section out of the bottom of the pack, and place a heatsink on the outside of the pack, and screw it to the heatsink on the radio, a bit of thermal paste to join the two, and you would have the heatsink doing its job again
@@spr00sem00se I'd love to see it.
@@temporarilyoffline well, I have come to conclusion that manpacks etc arent something that im going to be using, I live where there arent any winlink nodes etc, no meshtastic available, so really most of what I can hear is on 14mhz and lower. I was in the process of making a portable system in a toolbox with batteries etc, but in reality i can just pop some crocodile clips onto the car battery and make do like that.
Ive put extensive thought into it for a SHTF scenario, and the result of the thought is that I dont know anyone else that I care about who would be in communcation via ham radio. So handhelds for local use and an HF rig for long range info gathering are where its at.
weather forecasts and news bulletins for ships are a good source of info etc.
If you actually want to use that yeasu rig in a pouch, I would guess that the fan is blowing directly onto the final transistor like it is in other yeasu models I have, so you need ot be careful it wouldnt ever suck water or too much conductive dust in, I would say a duct with a dust cover, and a drain hole for incase water snuck in would work. You could likely forget the exhaust if you externalise the heatsink.
to externalise the heatsink, I would file the back side of it flat, then hunt a suitable heatsink to bolt to it, and use a thermal pad instead of paste, because hand filing flat wont result in a flat enough surface for paste to be of use, a thermal pad will deform and join the two heatsinks nicely.
🤔 High power Sat work in a shoulder bag? Great video, got me thinking on repurposing one of mine.
2 rigs for that! Guess I need another one
You should do a water proofing treatment to the material first! I would suggest micro crystalline wax and tung oil mix.
Thanks for the suggestion, I'm always looking for ways to improve my builds.
Another option since you’re not using the little pouch, make another pass-through and put all your digital stuff in the little pouch and then you’d only have the power cord and the digital cord coming out of it
I need to find a way to combine the pi and the digirig and reduce the cable nightmare. Then I need to add GPS.
I wonder if you can add either a folding solar panel or a solar power bank to allow you to charge if on foot and not near a power source
Would need a bigger backpack for that!
What if you mounted the antenna on the outside of the pack and it is supported by the molly? Like make a small hole out the back of the pack. That way, you could fish the antenna up in the molly for a little protection.
That would be great!
I am looking for more information on this post there. Build this all together and work radio bag how do you get the radio to work on a battery pack and what kind of radio is it
This is a Yaesu FT-90. To get it to work on a battery, find a battery that is 12v output and make a connector to attach the battery to the radio. I use Anderson PowerPole connectors. Most radios operators have standardized on those for 12v operations. I have a video on making those on the channel as well. Let me know if you have any other questions.
I'd find someone to 3d print you a bracket to attach the antenna to the body of the antenna so there is less sway and cause stress on the antenna connectors.
Good idea
@@temporarilyoffline also you could arrange the data stuff in the mesh pocket to keep it more organized
@@Chris_KI4WCO pocket's too small, I tried
If you replace the strap with Tubular Nylon you could hide the antenna inside.
That's a cool idea!
Did this with a Kenwood 800 MHz trunking xceiver about 25 years ago. Dropped everything into a Radio Shack CD player shoulder pack, worked real good! Used a NiMh battery pack with the radio tuned to low power at about 5 watts. Very convenient for portable ops. Out preformed an 800 MHz HT.
Checked the link for the antenna but it only lists the soft j-poles, nothing like the folding mail style antenna. Any other links to another site?
Hey, thanks for catching that! I can't believe I forgot that link: 👉 Abbree 42.5" Foldable Antenna: geni.us/T2SqnHR

Or... you know... Be a good operator and take it out of the bag if operating conditions dictate.
Do you have a video on getting a battery and how to setup the battery for a radio like this?
I actually just made one in battery math: th-cam.com/video/_P2vvo0y05Y/w-d-xo.html should help make the decision... But I've never gotten a battery and not found abuse for it. In this config I'm using a 3ah battery. It will last long enough for my use case. But maybe you'll need something bigger? The video will help with some of the math. But after that, the real world is the real test!
@@temporarilyoffline I found a IC-980 Pro for like $49. After seeing your video I was like oh this would be good.
@@unclegamer3092 never heard of it before, pretty cool
Nice build TO , I might have to try one for my 8800

I was looking for a reason to buy a Vero VR-N7500. I think it serve pretty good.in this role.
I don't have one, so I don't know if it will fit in the bag ... But everything else is pretty good to go

I have to do this with my ft90 now!!!
It's a cool setup, just mind the heat!
you can use a handheld hole punch the kind that looks like pliers,
If you can get it past all the fabric, sure that's another way to do it.
Where can you buy a cat assault backpack like this?
Check the links in the description, I got you covered!
Awsome setup! But do handheld antennas and radios like this even work together really? When I tried something simmilar with a CB radio the performance was quite sh** to be honest.
Bigger is better and just make sure the antenna is rated for the power you're trying to put out.
@@temporarilyoffline I tried a folding antenna from the same brand but for CB and a telescopic one that is even longer but I heard that those antennas only really work well on handheld devices because the person holding it gives it some sort of ground. Sorry, I'm pretty much a noob and also not a native speaker 😂
Enjoy your videos 😎
Thanks!
I see your heatsink is on the back of the unit. Any worry about overheating since the warmed air can't escaped as designed?
Nope, if I'm going to be operating beyond the capabilities of the bag, I'd just take it out of the bag.
So my question on this build: how much of a difference would you see if instead of the Abbree you use a Signal Stick? I have not looked at the Abbree, is it going to do a lot better?
That's a good question and pretty hard to measure. The Abbree is an EFHW, so "more wire in the air", but there is the transformer at the bottom. The Signal Stick is a 1/4wave and no transformer. Both are "resonant". I made an assumption and now you've got me wanting to testing that out.
@@temporarilyofflineI was thinking of the signal stick as well. It might roll up inside the case still connected to the radio.
@@BenjaminHeyser Wouldn't be as eye-catching though 🤣
Great video! Thanks again!

That's cool. Too bad none of them are available for sale right now.
Yeah. It's a discontinued model I found at a hamfest. I'm looking for a modern radio that will fit that bag and I'll update the video when I find one.
How does the radio’s heat sink and fan cool it if jammed in a bag? Won’t the radio potentially overheat quick?
Yep, if you're gonna be heat loading the radio, you take it out of the bag first. Applies to all radios in hot situations.
Total newbie here. Please excuse the basic nature of the question, but to what purpose is the digital aspect of the setup? Can you either through the Pi or through a separate PC or phone use this for network access?
Thanks in advance. Love the rig. If you were not going to use the external pocket, wouldn't the Pi 4 fit?
You can send digital communications through the radio other radios using the raspberry pi computer and your cell phone as a "keyboard/screen/mouse" or use it "at home" with a real computer setup. In part 2, I show how some of this works: th-cam.com/video/FECIfApYFjE/w-d-xo.html Check it out!
@@temporarilyoffline Thank you, it looks fascinating.
@digitalranger4259 it's fun for sure
Quick question... I know.
The radio has a heat sink in the bottom, do you think that you're gonna have an issue with overheating with the radio?
Every radio has an issue with overheating. A good operator takes that into consideration. I have some radios that I have installed fans into and Yaesu has had problems with the 817 burning out finals in "good" operating conditions. Just gotta be on your toes!

As with anything in ham radio "it depends" - at a hamfest, I'd expect I wouldn't get a full day out of it with everybody beaconing APRS in range and making me re-transmit.

No issue with heat buildup?
Operate based on operating conditions and you'll never have to worry.
The right angle UHF SO239 adapters and the UHF SO239 connector at the back of the radio does not allow an exact 90 degree connection. All radios with the UHF SO239 connector seem to have the same problem. They have all been machined incorrectly! I have never seen a UHF SO239 connector or adapter which permits an exact 90 degree connection so the antenna is at 90 degrees to the radio, which is obvious with yours as well. The 90 degree connector will ALWAYS be about 1 degree out at the connector which means any antenna will be obviously crooked by a considerable amount at the tip, as is yours!
We've reached Peak Humanity!

Not in my use case, but as with any radio, you have to operate properly.

I found this bag from gigaparts works really well for the 818: www.gigaparts.com/green-tactical-sling-bag.html use code KM9G at checkout for some savings!
My concern is that even if the bag is unzipped, it might overheat.
There is always a concern with heat disapation, for sure.
What about keeping from overheating?
Smart operations! Even outside of the bag you have to keep an eye on heating and duty cycle.
Do not under any circumstances run the FT-90 inside a closed pack. It'd be the last time you do as you'll fry it. Half unzipped won't help much. That fan needs to run on high.
Yes, mind the heat as with any radio. Thanks for looking out!
