I just have my 5 element yagi pointed southwest, with vertical polarization. The radio is an SDR dongle with a 410-755 MHZ bandpass filter attached. I use the rtl_power script to acquire the spectrum, with 10s averaging.
From the doppler, I can tell the general direction of the satellites. So the CAPE-3 signal at 437.325 is consistent with the satellite going S->N, and whatever the signal at 436.6 is appears to be from an unrelated satellite crossing the T of the antenna.
Since there's only a very weak signal at 435.75, I can't really tell what the doppler is.
I will keep listening, especially if people want to try TXing to the satellite, as it's probably better to have separate stations on the RX end to ensure it's not just a harmonic being picked up by the TX station.
