Re: GNU Radio support for educational use

That's great news!

I am running the RSP1A with gqrx using soapysdrplay with good success but it always seemed a bit clunky to me. I'm going to play with gr-sdrplay in grc and if that's working, I try it with gqrx.

Thanks a lot!

Re: gqrx Opinions ?

Hi Bob, I'm running gqrx with an RSP1A on Linux, so I can only comment on the program itself (features, GUI etc.), not the installation process, but it's basically the same situation on Linux as on MAC: You have only two choices, gqrx or cubicsdr. I also tried cubicsdr, it's nice but when I tried, i...

Re: FT 990 IF output

I you want to use the RX out, you need a splitter because the RX ANT button on the FT990 simply opens the connection from T/R relay RX side to receiver input and makes them available as RX out resp. RX in externally. I use a Micro Circuits PSC-2-1 for this. This gives a 3dB loss, but that does not m...

Re: Rig Control Delay - IC7300

Do you have bidirectional synchronization enabled (so if you change the frequency on the 7300, SDRUno would follow)? I see the same problem with an old FT990 at our club station but did not investigate it yet. If I configure the unidirectional synchronization SDRUno -> FT 990, the TRX follows SDRUno...

Re: FT 990 IF output

I just looked up the mfj 1708. It is a T/R switch.

You don't need it as you want to connect your SDRPlay to the IF output and not the antenna.

Re: FT 990 IF output

Is your FT-990 modified? We have an FT-990 at our club station and it has no IF output.

Re: VFO skips

I have the same hardware setup (TS590SG connected to PC via USB, RSP1A), but different software (Linux, gqrx and home made connection software) and I do not see this problem. Do you synchronize the TS590SG to RSP? I had a similar problem when I was writing the "connector" between gqrx and ...
