RSP2 Pro and openwebrx...questions
Posted: Wed Aug 22, 2018 6:39 am
I have a RSP2Pro and running with a Raspberry PI3 with openwebrx.
All is working in general. I use SoapySDR with the driver-wrapper SoapySDRPlay, the driver-base for SDRPlay is 2.13 from the SDRPlay-Download-website.
openwebrx starts with rx_sdr and parameters.
But there are open questions for me.
1. How can I select in this combination one of the 3 possible ant-inputs ?
2. How exactly I need to setup the rf_gain parameter ? There are 2 in RSP2, RF-Gain and IF-Gain. How tell I the driver these 2 different parameters like in SDRConsole ? (RF_Gain in range 1..8 and IF-Gain in -XXdb). I read with the rx_sdr you need rf_gain in db. I check different values from 0-35 but the results are not really good.
3. How can I switch the IF freq ? Zero-IF generates a lot of broadcast interferences (rx-ant is a 80m/40m double dipole on ant1), I read better is to switch to IF-low (or so on).
Whats the best practise to configure these options with openwebrx ?
Btw, working with SDRConsole and WIN the RSP2 works much better because the possibilities for a better setup - with openwebrx I cannot make it equal.
