Hey everyone,
I worked the AO-7 pass just after 00:00 UTC here because it had a maximum elevation for me of almost 89 degrees. I wanted to see how much, if any, my ability to work would expand when runninng a half-watt if a used CW instead of SSB.
On this pass, at least, I had a copyable signal from 30 degrees to 30 degrees, and made a partial contact at 00:15 UTC with a station whose call sign I did not fully copy - which is totally my fault. The call was WA4 (or, at least, that's what I copied), but I didn't catch the suffix. The signal faded slightly, and I didn't ask for a repeat. That's embarrassing, and I apologize to the operator for that. When he called me, AO-7 was below 35 degrees. I reported a 589 to him, and he gave me a 559, which exceeded my expectations. When we finished the QSO, AO-7 was at 28 degrees elevation to my location, and I faded into the noise.
It'll take a few more passes, at least, to say with some measure of certainty, but it appears that, for my station, I probably can expect to have workable signals at a half-watt out on AO-7 at 50 degrees elevation and above in SSB, and at 30 degrees elevation and above in CW. Given the compromises I choose to have with a fully portable station, that's not to bad for milliwatts.
73 to all,
Tim - N3TL
I can't figure out what's wrong here. I listen for AO-7 on the past your were talking about and was not able to here it at all and it went as high as 89 degrees here. I thought maybe the pass times were off but listen well before and after the times and still did not here it. However, I hear all of the other satellites at the appropriate times. Was AO-7 in A or B mode? Usually I hear AO-7 horizon to horizon (except directly overhead) with a Ringer II vertical. I'm missing something here. I enjoy working AO-7 now I seem not to be able to hear it.

Hey Reid,
AO-7 is pretty much "locked" in Mode B for the time being because of the nature of its orbit. It's not getting to a point where the system toggles between Modes A and B, but that's fine with me because Mode B is the best mode for me and my station.
I heard myself for the first time at about 00:06 UTC, and moved just below 145.940 to call CQ in CW. I didn't have any takers, so moved up to about 145.944 and started calling again, which is where the WA4??? called me. Our QSO started during the 00:15 minute and ended during the 00:16 minute.
From what I could hear, the satellite was very strong. I don't know what to say about your not hearing it. I suspect you've checked the antenna on a terrestrial repeater or simplex and know that there's no problem with it or your feedline. I hope you get it figured out.
73,

I have a 12 degree pass here at 01:55 that I am going to try. Not sure whether there will be enough sun on the bird but will try. Don't know why I'm not hearing it, since I hear the others fine. Will try VO-52 as well which comesinto view shortly as well to make sure I hear it.

Maybe time to get that tape recorder back out??

No doubt. I've gotten lazy with the ability to work from a shack, such as it is, and write down contacts. That didn't serve me well this evening. -------------- Original message from "Roger Kolakowski" [email protected]: --------------
