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 ...

Re: Drifting "birdie"

That's a known issue with the RSP1A. See this thread:

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.

Re: RSP2 Pro HF reception question

I have no idea for your problem, but I can say that the RSP sensitivity on HF is at least as good as the TS590SG. What antenna are you using on HF? I connect the RSP to the DRV output of the TS590SG which I configured as RX output, so the RSP and the TS590SG are basically connected to the same anten...

Re: Can you use the SDRPlay2 as a pan adapter?

I don't know the details of the TX mixer string in the 870, but the 850 string has inverted spectrum in the 8.83 MHz IF. It's not a great drama, you just have to remember that signals below CF displayed by the RSP are actually above CF at RF, and that on SSB the demodulation sense is inverted, e.g....

Re: Thread for gr-osmosdr and GNURadio problems/ideas

What is your platform? I have the RSP1A running in GRC with Ubuntu 16.04 right now. It's an old flow graph I built for the RSP1 but it is still working with the RSP1A. Gnuradio and osmosdr are built from source. I am using the osmocom source with the properties below: Screenshot_20171230_151056.png ...

Re: SoapySDR build failure

ldd /usr/local/bin/SoapySDRUtil should show what the exact location and name are where SoapySDRUtil expects the library. On my system it gives: ldd /usr/local/bin/SoapySDRUtil linux-vdso.so.1 => (0x00007ffe7d5b6000) libSoapySDR.so.0.6-dev => /usr/local/lib/libSoapySDR.so.0.6-dev (0x00007f2b2708d000)...
