Today I was able to get a PSK signal through PSAT2, and it was recorded by KO4AQF in FL. I sent with a dial frequency of 29.4815 MHz and an audio frequency of 1000 Hz using DopplerPSK. It was detected at ~2650 Hz, which means the appropriate dial frequency to use is actually about 29.479 MHz. This agrees with the Brno team's website, where they say "The main function of the transponder is to receive PSK signals from 29.48 MHz uplink (passband from 29.4804 to 29.4826 MHz)."
I also measured the downlink to be about 3.6 kHz higher than 435.350 MHz.
