I got my Pluto mounted at the dish, which is a 1.8 meter PF. I have only opened up the Pluto frequency width and enabled both processor cores in the firmware, which is V0.33. Th Pluto xtal oscillator is stock. I ran it into the AD CN-0417 pre amp that I was going to use to feed my SG Labs 20W PA. For testing I thought I would see if the satellite could hear me just using the CN-0417 output direct to the POTI, I did not expect it would...
The software is SDR Console, locked to the beacon, and it "talks" to the Pluto via an ethernet cable and ethernet to USB at the Pluto. In SDR Console I have an RX offset of 9750MHz set and a TX offset of 6089.5MHz set. Is this TX offset correct please?
I TX'd an FM signal with the software set to 10.489730 I could indeed see my signal on the UK based Goonhilly web SDR,, but it was way off frequency, and drifting in steps. Is this to be expected until I muster the courage to try and remove the stock oscillator and feed the PCB with a GPS locked 40MHz from my Leo Bodnar GPSDO?
Given the signal strength from just the CN-0417 (although I am unsure if it's linear at that level), once the frequency issue is sorted, might I even be heard on SSB without the PA?
Thanks for any advice. Chris, call sign 2E0ILY
