Thanks for watching, 73!!

Indeed! Thanks for watching, 73!

I am hoping they get it in a regular schedule since it’s near end of life span. It was listed as a three year mission and we are basically at that now. I checked last night at the 10:30 central pass and it was offline.

Yes they have all the info in the SAT Controller and it tracked flawlessly. 73! The timer did shut it off last night. I tried on a 10:30 central pass and it was off. Hopefully they kick it back on soon.

Thank you , 73!!

That spot in Utah has to be the most beautiful place I have EVER done radio!! I’m the same way every time I see it. You should totally take the leap and try to work some satellites! Even if it’s just an FM satellite with an HT setup but the 705 and 818 would work! Lots of guys use two 818’s so I’m sure it would be the same concept.

Thank you Simon!! Hopefully you can catch a pass before it shuts down, it has great audio. 73!!!!

I have activated a few parks via satellite. I have a couple old videos on the channel of some. Maybe you could take your setup out to one and get it started over there! I am running the WiMo X-Quads in Right Hand Circular Polarization. 73!!

I am running a dual LMR-400 feedline setup to the two antennas. Teh radio handles everything fine itself. The only time I had any RF issues was when I was trying to get the antennas setup. At first I used a metal cross boom, and I had the antennas both end mounted. The metal boom caused some reflection, but the big one was the driven elements were not lined up parallel. Now they are set on the boom so the driven elements are perfectly side by side, instead of one facing into the back of the other. Once I set them up with a fiberglass rod and the elements parallel, ZERO RF.

@@W0CYC-HamRadioEndeavors That's really useful info, thanx again Rob. I managed some USA contacts on RS44 yesterday using separate radios and a high-pass filter on the RX radio without any problems :-D Now considering an antenna for circular polarisation :-D Do you know whether most amateur satellites use linearly-polarised antennas?

That’s great!! I believe most are and RHC Polarization seems to work the best at countering the spin of the satellite to balance out the polarization.

@@W0CYC-HamRadioEndeavors Sweet, thanks Rob. 🙂 Maybe catch you on RS44 soon 😀

Fingers crossed!!

Awesome! I don’t work AO-7 very often. I have high swr at that transmit frequency since it’s so low in the uhf range. I’ve never tried to lower the swr since I’m dead on for everything else.

Thank you! The 9700 automatically shuts power off to the preamp when you hit transmit. There are two preamp controls on the 9700, the internal is activated by the button on the faceplate. The external power has to be turned on in the menu settings then activated/deactivated through the Menu button under the screen.

@@W0CYC-HamRadioEndeavors Great! That's useful to know; the manuals seem not to mention that. :-) What sort of erp, on 2 metres, do I need to get into RS-44 when it is on the horizon?

At the horizon, shooting through trees, I will run 60 watts ssb ONLY if I can hear myself back. I have around 2db of system loss and 10.5 db of antenna gain so the ERP on that would be about 380 watts. I have made contact with Spain at 2 degrees with this setup on RS44.

@@W0CYC-HamRadioEndeavors Great stuff! That's very useful info; thank you. I think I can muster that erp. Hope to catch you on the bird! Does it reach to England, from the USA, when at apogee?

You can get into western Europe with it for sure. I am just west of the Mississippi center US and can get Europe and deep into South America. If you are much west of me though it gets tough to impossible pretty quickly. Of course it’s at low angles and a perfect pass across the Atlantic so you have to find the right pass. If you are lucky enough to be on the East Coast of the US you can get passes pretty deep into Europe.

Thanks for calling into the park! This was a super fun trip out west. This series of videos was a lot of fun especially the Twin Peaks video. 73!

Thank you! Lou was a great guy. He originally was assigned the callsign in 1954 so it’s also fitting I am assigned the call 70 years later. 73!

You should jump back in! There’s a lot of new radios coming out this fall and the used market is crazy good right now. The cost of a new IC-7300 has brought the entire used market back to reality.

Good evening Steve! I apologize, I haven’t been doing many videos this month. Life has been super busy and TH-cam has been the last thing on my mind. It was awesome to hear the expedition on RS-44, and I am super happy you got them as well! I hope to catch you again soon, 73.

No. Apparently it’s suspended by fishing line and kind of scoots past us until it reaches the edge of the earth then comes back the opposite direction 😂

Thank you, 73!!

The ISS repeater is 145.990 uplink with a 67hz tone, receive is 437.800. You will need to account for the Doppler effect on those as well.

Thanks for the kind words! You will be much happier with the SAT Controller. Once you have it dialed in and get used to the quirks of the old radio you will have a blast! Let me know how it all works out for you. 73!

Thank you Sir!It does work extremely well. Thanks for stopping by, 73!!

My 9700 is controlled by the CSN Technologies SAT Controller. All Doppler is done automatically by the SAT. if you do not have access to one it’s a bit more complex. FM satellite Doppler is pretty easy. On receive you start 10khz high and work your way to 10khz lower than center frequency. The transmit starts about 2.5-5khz Low and you raise it 2.5-5 kHz higher than center point as the satellite goes overhead. The SSB satellites are a lot more complex because the transponder is taking an LSB signal on vhf and flipping it to a USB signal on uhf and vice versa. If you need further guidance shoot me an email. It is good on QRZ. 73!!!

Yes it is. The crew has access to the radio onboard by simply grabbing the microphone. For anyone on the ground you need to work the crossband with the 67hz tone on transmit. 73!!!

See the above comment. 73!

The 1-Watt wonder strikes again!!! 😂 Great work as always David, you always seem to do fantastic with the most unthinkable setups. I’m more than ecstatic to see you on satellites man. You are gonna love this journey, 73!!

😂

It was the proverbial S!!T Show at times that’s for sure. 😂

Absolutely! Jessica is using an old IC-821 and just BOOMS in. 73, thanks for stopping by!!

He was a great guy. I found a callsign book online from 1954 and he had the callsign then. I’m trying to find more to see when it first was assigned to him. The only records of it being assigned in the FCC database is him and me so that’s pretty cool.

Was it AE2MP? I’d love to catch you but I’ll be at work

@@W0CYC-HamRadioEndeavors Yes sir. He's was booming here.

Matt has an awesome station! We chat quite regularly.

Absolutely Steve! I appreciate you checking it out. We miss you on the satellites you definitely need to get back in the saddle. Jim was killing it at the Park. I absolutely LOVE listening to the portable guys get tons of calls, and trying to steer others towards them if they don’t know the portable is there.

Yeah it’s a tough little SOB to work. My longest contact is to Florida a little over a thousand miles. It only puts out .040 watt! Preamps are a must for This little guy.

Well now I have to learn me how to add a bird into my opengd77 sat files...thanks now I have something to do!

Yeah you do!! You also need to do an instructional video on that software for your mobile and your HT!!

@W0CYC-HamRadioEndeavors I got it added to the OPENGD77 Firmware! I probably should but man it was not easy to flash on the HTs. But I will work on that! Good idea for a youtube video! See ya at 03:15 UTC

Yes it would be ! I honestly didn’t even know about it until i watched your last video. Then I went searching your channel for more videos on it.

Yeah you do!!😂 Great job Don, 73!

Good QSO!

After like the 100th time being asked and explaining it via email I recorded a short video. Another example of why I should do more instructional.

Absolutely! I’ll do that with ya for sure. The final picture in my intro is my local park I activate. I’ve done satellite POTA there a bunch of times.

Dude I got ya!!!!! I was recording the pass so you will be on the channel on a couple days. Hell yeah man I’m so happy to hear you on the satellites!!! Now to get you on a linear satellite so we can rag chew on ssb. 😁

@@W0CYC-HamRadioEndeavors I was using a tyt7800 for that last pass. I made a youtube short of the junk i was using this last pass. I have a 991a that will do 2m ssb. I need to get an antenna for it. Thanks for listening for me. I got you in the log.

Hel yeah man I’ll check it out! You will need something full duplex to do the linear satellites. Correct me if I’m wrong but I think the 991 is not full duplex between 2/440. I’m super excited for you man it’s a great feeling to finally get on the satellites.

@@W0CYC-HamRadioEndeavors No but it will run split 2m to 440. I have a lot to learn

Ok it could be done but it will be super tough. You would have to do manual adjustment of the Doppler for both RRS smit and receive bands. When you get ready to try get ahold of me, a long phone conversation would be best to see if we can get you on.

Awe man so close!!! Great try with a 5 watt HT! Keep trying the ISS but it’s so packed you might want to try PO-101. It is UHF up VHF down and is only active usually Monday, Wednesday and Friday. The downlink Doppler is easier to adjust but the uplink Doppler is a little tougher since the UHF needs changed quicker. I appreciate you watching and hopefully I can get a contact with you on the channel! 73, Rob

@@W0CYC-HamRadioEndeavors Thanks for the info! I'm newly licensed but have SWL for years to HF and the ISS. Finding your channel has peaked my interest into Sat comms, and still looking for my 1st contact via ISS. I'll get you ITL eventually! Keep up the great content!

Wow that’s awesome man!! I appreciate the kind words. That my friend is what the channel is all about. I definitely look forward to hearing you on!!

Absolutely! I only run 50 watts at the very beginning and very end of a pass. Which equals only a few seconds of actual transmit time. I will extend the tripod and mount as high as it will go which is about 6', then stand as far directly behind it as I can get. Thats pretty much the best you can do.

Hey David!! That is fantastic news man! Do not give up, it's tough to get that first one then its downhill a bit. I have a video on the channel on why I changed the callsign. It is a pretty cool story if you are interested. I'll be listening for ya!! 73

@@W0CYC-HamRadioEndeavors I heard you respond to this last ISS pass. I dont know if you heard me that repeater was packed. Plus i suck at this satellite thing.lol 😂

It’s beautiful!!

That is awesome to hear man! I remember hearing you on that pass, but couldn’t find a spot to get in. Keep up the good work. That’s why I like doing these videos…showcasing the other side of the mic 73. Hope to catch you soon.

Thank you Jon! Do not discount your station! You do such amazing work with such a modest investment, it should be an inspiration to all. Big money gets big results, you are rocking it with what is needed to get it done and that is extremely admirable. Please keep capturing passes from India for us all to see my friend. I love hearing your side of the world. Anyone reading this please check out Jon’s channel. youtube.com/@johnsonstechworld?si=fFxvnHc26gwdYhDB 73!

@@W0CYC-HamRadioEndeavors Thanks a lot for the great encouragement. 73

Nothing special, just what every operator should practice. Hopefully more remember that in the future. Thanks man, it’s been a tough first week but that’s what it’s all about. The next challenge and the next big success. 73, catch you on a pass!!

I appreciate it, thanks for watching!! 73

Thank you I appreciate you watching!! 73

No problem! Thanks for stopping by and saying hello. If you need any tips let me know.

Absolutely Don, it’s always fun to get you with your portable setup!! I subscribe to your channel and I would love for my subscribers to do the same. If you are reading this, please check out Don’s channel!! youtube.com/@w8cptcptdon?si=hkuMmyrTf1XodyXE

@W0CYC-HamRadioEndeavors thanks ill give you a plug too!

Thank you sir! It makes it much easier to track and operate. Take down is simple as well.

Yes sir! I’m at the Cardinals game now. Private box with all the food and drink you want.
