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 TS590SG an...

Re: Use of Left and Right Channels?

When I am trying to work a split DX station, I have the RSP1A tuned to the DX transmit frequency on the left ear and the TS590SG on the right ear, so I hear the DX and observe the pile up at the same time. If the DX listening pattern is at least a bit deterministic, I can guess where the DX is liste...

Re: SDR play connected via IF out and transmit

You are on the edge of damaging your RSP with the Active Whip. According to SDRplay the safe limit at the antenna input is 0 dBm continuous and 10dBm short duration. I didn't know that when I posted nearly one year ago. I do not use the whip while I am transmitting, it was only for testing and more...

Re: SDR play connected via IF out and transmit

The whip sits on the top of one of the masts that hold my multi band dipole. Distance to the 80m dipole end is about 3m.

Re: RSP2 Pro HF reception question

I have connected my RSP1 to the DRV output of the TS590SG configured as RX out. No relays etc. needed. You hear the TS590 TX signal in the RSP, but below RSP limits.
