Hi all, after our return from european field day this weekend, we sorted out through all available receptions of PSAT2 telemetry and SSTV. As very valuable source we use the SatNOGS observations. There I have found several passes over US, were PSAT2 was transmitting because it sensed the PSK signals on uplink, and I have found two stations there and decoded their calls as W5SAT and K4KDR. Congrats gentlemen! If you can post the power/antenna used in experiments, it would be very valuable for us. Therefore we can state, that also the PSK31 uplink is in great shape and waiting for your further experiments. Tomas OK2PNQ and Ales OK2ALP
Congrats on the success of PSAT-2, Tomas & Ales!
Please note that KC9ELU has activated the PSK31 transponder on PSAT-2 as well.
As for my setup, the location is grid FM17es (lat/lon = 37.7784 / -77.6093).
PSAT-2's elevation is quite low here, of course. It's been great to see so many stations work successfully through the 2m APRS digipeater, 2m APRS-to-Voice engine, and 10m/70cm PSK31 transponder even with the satellite's low orbit making things a challenge.
On my 10m uplink, I've been running 75w to a MyAntennas EFHW-8010 oriented South-to-North and located on the North side of my house about 4 meters off the ground. Pretty much a worse-case scenario for communications to a satellite so far to my South, I would think. This 130 ft. long-wire type of antenna was put up mainly for 80m NVIS work but does a great job on other bands as well. I think I'll put up some kind of vertical antenna for 10m when time permits to see if that improves my coverage to the South.
My 70cm receive setup is better, although I should mention that I'm surrounded by heavy tree cover. So, except at high elevations, I do much better in the Fall/Winter than during the Spring/Summer months. The 70cm antenna here is a Wimo X-Quad on an AZ-EL rotator and benefits from an SP-70 LNA at the base of the antenna.
The 10m/70cm PSK31 transponder on NO-84/PSAT, and now PSAT-2 is a great challenge and a lot of fun to work. Let's hope the addition of another satellite with this capability prompts more people to enjoy it!
