Listening for QIKCOM-1: Just to be sure. If the antennas were not released by the host, then no one will be able to decode it but we are HOPING that someone can hear it responding by EAR. That is, put your receiver in SSB mode and listen carefully by ear. Then ping it with as much AX.25 FM power as you can. No more often than every 12 seconds, since it has a DUPE filter of 10 seconds.

Then see if you can hear a correlation 1 second avfter each uplink for a possible digipeat…

Greetings Bob, it’s been a while since we spoke. Perhaps “Outernet” was the subject previously.

Yes, Malcolm was kind enough to refer me to recordings from a number of diverse receiver sources last night and I only found one with actual packets – which decoded to be digipeats through PSAT.

Additionally, I had a nice overhead pass of QIKcom-1 last night and as I’ve done many times before, tried to exchange APRS packets with it at up to 50w thru a RHCP yagi gain antenna (X-Quad). No replies were heard, unfortunately.

73!

Thanks!

Data number 59348 makes sense. At first I was totally confused by the continuous tone traks aAND the fact that they followed Doppler. Meaning they must be coming from the spacecraft.

Then I realized that maybe the receiver is Doppler trakcing and so any fixed tone in the passband would then appear to follow Doppler when in fact it was constant. So, now that I ignore those, I can see the packets.

Bob,

For reference, here's some NO-84 passes: https://network.satnogs.org/observations/?norad=40654

However, the visual appearance will vary based on gain and station configuration. The SatNOGS team responded this morning and eliminated all of the observations I'd found. The weak signals appear to be NO-84 off the back of directional antennas. A few decodes from NO-84 and one terrestrial station.

I've copied Scott Chapman, K4KDR, as he tried last night with negative results. My station is portable but relatively robust. As time and weather permit, I may find some acceptable passes and try to warm it up a little!

Have a great day,

Malcolm

Yes, that is going to be a problem. They are both on the same frequency along with PCSAT NO44, and so one has to ignor any passes when both are in view.

I still think the best test is to be pinging it once every 12 seconds and see if there are any responses. That will be proof.

I have not looked at waterfalls before of a good packet, so I don’t know what to expect. Maybe you could capture a waterfall on a strong pass of NO84 and lets nail down an example of a good pass.
