Super interesting experiment, hoping for an update! You're asking almost all the same questions I have. I'd be curious about power if using the "power eliminators" would make it any cooler or if you'd introduce any noise from your power source. Also I like the antenna idea, you could pretty easily add a j-pole with the design.
I’m hoping to test it out this weekend. I have gotten some good feedback in the groups so I might need to change some things. Either way we’ll see how it works out.
This is the third porta-peater youtube I have seen. Looks much easier than the one my buddy and I had about 13 years ago (it was far bigger, heavier, and harder to set up). When will someone put up a video that actually shows the radio configuration process? I see in the comments that you have later videos. I will check them out.
@@SlowGoose On which to set up roger beep, how? On which to set up ctss. I think I know, but some may not (xmit, rcv, both)? Lengths of interior cables if it matters? Why two separate batteries? How to make holes for charging and antenae that don't leak. Ours was in a metal 40mm grenade ammo box and we had leaking problems. How to prevent heat buildup. Is there any programming to do on the repeater controller?
9 watt 5vdc panel? @ what current ? Baofeng pair will need 1.8 amps xmit, but I'm not sure these have bms on the extended batpack. I purchased the alkaline/low to mid grade nimetalhydride AA. Charge rate 850ma to 1.2 amp each, depending on workload. Picking up the components to build or buy one outright, 2.5 amp regulated charge controller.
Before you mentioned the heat issue I was thinking..that thing is gonna overheat out in the field because the case is too tight for waterproofing. But good luck, hope you find a solution.
I have my concerns still. I upgraded the tx to a 25 watt ht and it does work a lot better. The tx radio has an internal fan and produces substantially more heat. I have not added a fan yet but it’s become a necessity
That’s what the duplexer is for. I have seen them with 2 antennas and that’s going to do more harm than good. With cheap radios and incorrect spacing of antennas you will wipe out the receiver of the rx radio.
@@JOHNSMITH-ug2mt it would work a lot better with two antennas. the receivers on the baofengs dont have enough rejection to work good with the duplexer.
If you check out the next video I wound up having to address the 2 meter issue. I just set it up to cross band and it eliminated the need to stuff a full size duplexer inside the box. Also these batteries do charge while the radio is on.
It was tested on a 3 element beam and the range was awful. The tx radio has been replaced with a 25 watt. The diplexer was replaced with a duplexer. That just has to be tuned now. Watch the rest of the videos.
3:52 min mark with Not a Rubicon in the background; excellent taste!
Good ole Randy. Lol
I have four UV5R's. I have to do this. That is a wicked set-up.
looks good, any chance you can make a list of links to the parts you are using?
Sure, I’ve been trying to put one together just to figure out what I have into it. I should have it together over the weekend.
@@SlowGoose awesome thanks!
Any update on a list looking to build one myself and love the set up

Noise from the power source may be a factor. Open up the battery case, its mostly empty and line it with foil.
How far apart do the antennas have to be so they don’t interfere with one another?
This only uses one antenna via the diplexer.
But what parts do I need and how do I build it?

Radio setup as far as what? Frequency? Offset? What would you like to see?

Very good questions to think about.

soo those duplexers are the trick to make the repeater box to work? what specification should I look for those?
It’s not required for it to work but it is required if you want to use 1 antenna.
@@SlowGoose with two antennas happens the same
Does this work with Quansheng also :)?
If the plug on the interface fits it will usually work. I have used it on several different radios
@@SlowGoose Thank you for the answer!
Im wondering what kind of duplexer you are running, i cant find any that fit my price range and simply plan on using 2 antennas
9 watt 5vdc panel? @ what current ?

I’ve never had it out long enough where I’ve had to use the solar panel. But it is not enough current.
Noice.
New Subscriber.
Do you have a link for the foldable antenna?
Thank you,
Here you go. This is for the 42.5 inch. That’s what I use. There are several lengths

ingin memiliki duplexer mini..tapi di sini harganya mahal 😊 kerja bagus bro
The duplexer is the Achilles heel to the entire project.
What would you say the range is on a repeater like this?
It wasn’t great. I will post a video testing the range.
Did you post a list of parts?
Not yet. I wound up rebuilding the entire thing. Changed a lot of parts. Just put it together last night. Should have a video about it this weekend
What make and model Duplexer did you use?
Anteenna tw-720d. It was the cheapest one on Amazon at the time.
What duplexer did you use ? How many watts out are you getting? And what is the swr reading between repeater and antenna ? Please
It’s mostly likely about 3.5 watts with a duplex
looks great
Nice idea
Thank you

Consider the duty cycle. Heat likely won't become an issue. You could attach the tx radio to a block of aluminum should be enough
I assume you used a duplexer, seeing as how you only have 1 antenna.
Yes, in the other videos I show the duplexer/diplexer
Interesting. But don't you ne 2 antennas? One to receive and one to transmit.
That’s what the duplexer is for. I have seen them with 2 antennas and that’s going to do more harm than good. With cheap radios and incorrect spacing of antennas you will wipe out the receiver of the rx radio.
Unable to see the Pelican case number. Can you provide that?
I believe it’s a pelican 1400.
Could never get this to work properly.
i wasnt thrilled with the results
@SlowGoose Great try though.
@@JOHNSMITH-ug2mt it would work a lot better with two antennas. the receivers on the baofengs dont have enough rejection to work good with the duplexer.
Thx@@SlowGoose
What duplexer did you use?
Originally I was using an anteenna tw-7200 but it is really a diplexer. I have since revised the build and will be posting a video shortly about it.
Those batteries will not power the radio while it is charging. It will also broadcast on 2m.
If you check out the next video I wound up having to address the 2 meter issue. I just set it up to cross band and it eliminated the need to stuff a full size duplexer inside the box.
Also these batteries do charge while the radio is on.
There need to add a fan.... Please show in your next video a schematic connection and how a repeater works.
That chinesim doesn't work. I've tried it.
I see two radios in a case. Nothing else. These guys never seem to go outside.
It was tested on a 3 element beam and the range was awful. The tx radio has been replaced with a 25 watt. The diplexer was replaced with a duplexer. That just has to be tuned now. Watch the rest of the videos.
