That's great, Roland! Thanks for the updates.
The elevation is still too low for me to receive any of the 70cm downlink, but I have been hearing some of the 2m APRS on 145.825.
It was great news to see the post from Bob regarding the orbit slowly moving north.
If you can, please monitor the 70cm downlink for any sign of PSK31 - since Bob announced that the PSK31 transponder was active, I have been transmitting on the 10m uplink on the chance that the satellite hears me even at such low elevations.

Scott, Just curious -- Does the 10m uplink have any bounce/skip off the atmosphere? Seems like you should be able to "reach" around beyond line of sight at that frequency. Right?

I can only speak to how it’s been working with the original PSAT (NO-84), which is VERY good.
With only a long wire HF antenna (http://myantennas.com/wp/product/efhw-8010/) suspended around 4 meters off the ground, I have often seen my PSK31 TX stream coming back down on the 70cm FM downlink at as little as 10 deg. elevation.
However, this time of year with leaves on the trees, it needs to be closer to 20 deg., but that's still pretty good.
So yes, I'm hopeful that I can be heard w/ a 10m uplink even while PSAT-2 is still in that southern phase of its orbital pattern. If PSAT-2 works anywhere near as good as PSAT does, it's going to be really hard to resist putting up a dedicated 10m antenna such as the PAR HF-28!

That last pix was from the top of my desk back in the summer of 2017!!
The hams at BRNO University delivered the PSK31/SSTV module for PSAT2 on-time and on-budget (free to us). They worked over the holidays to meet a very short deadline and delivered in February 2017 for a March Integration.
Then 2+ years of launcher and FCC delays and it finally got launched now! I guess whenever I powered it up, it must have been taking pictures.
Im sure it was frustrating for them to see all the launch delays, but each was only a few months and so there was no time (and risk was too high) to send it back to the Czech Republic for them to do any more tweaks... (Like I got to do on PSAT2 firmware for 2 years!)
