PhantomSDR+ with RSP1A or RSP1B

[9a7aof]

Hello,

I have two Sdrplay receivers (RSP1A and RSP1B) and I don't know how to get them to work with PhantomSDR+.

The Chinese RSP1 clone works fine with the miri_sdr driver, I tried several bands, everything is fine.

My start-miri
#!/bin/bash

killall -s 9 spectrumserver
killall -s 9 rx_sdr
killall -s 9 miri_sdr
#service sdrplay restart

#-------------------
#2Mhz ---27Mhz band
miri_sdr -m 252 -e 2 -s 2048000 -f 27800000 -T 1 - | build/spectrumserver --config config.toml > /dev/null 2>&1 &

exit
#------------------

I installed Sdrplay API, it is not needed for RSP1 when it works with miri_sdr driver. RSP1A and RSP1B don't work with the miri_sdr driver (waterfall does not work).

I am asking for instructions on what to do from SoapySDR and rx_sdr.

I also don't know how to activate bookmarks in PhantomSDR+. In Openwebrx I add them manually using the joe editor. What is the name of bookmarks.json in PhantomSDR+.

My operatihg system is LMDE 6 and compilation go without any problem.

websdr@edge:~/PhantomSDR-Plus$ lsb_release -a

Thanks!

For Soapy and RSP1 A/B you have to goto the SDRplay website and for Soapy here:

https://github.com/pothosware/SoapySDRPlay3/wiki

First install Soapy from scratch, then install the SoapySDRplay plugin.
Else it won't compile/install.

When Soapy is running you need to install https://github.com/rxseger/rx_tools

When that is running....then you need to make a line like this:

rx_sdr -f 145000000 -s 20000000 -d driver=hackrf - | ./build/spectrumserver --config config.toml

But modify it for the SDRplay driver.

However, I have tried this and couldn't get it stable, Soapy would stop sending data after some time and needed to be restarted.

Goodluck.

Thanks!

I'll try that in the next few days, I'm not at home.

Hello,

I configure PhantomSDR+ to work with RSP1A and SoapySDR driver.
Its work fine with bandwith 10MHz.

I have problem with MW Broadcast stations, they are very faintly heard, the switch -t means nothing, be it true or false.

Here is my start-rsp1a

My markers.json is edited by hand, it is NOT compatible with eibi.json, repeaters.json, CB.json and thist editin is very boring and takes a long time.

Is there any script that would convert the records from eibi.json generated in Openwebrx into a record that is compatible with PhantomSDR+?

What SDRPLAY API do you use?

As the github if filled with problems between Soapy and the V3.xx API.
If you use it, you may try a lower 3.xx version.

Or try the 2.13 API with the 2.xx Soapy driver.

Or edit the Soapy RSP-driver code and set the notch to false...as it's enabled by default and thus blocking LW-MW.

Hello,

I work with SDRplay_RSP_API-Linux-3.15.2, this API and SoapySDR driver work fine with RSP1 clone and RSP1A original.

I edited Settings.cpp

Code Select Expand

       SoapySDR::ArgInfo RfNotchArg;
       RfNotchArg.key = "rfnotch_ctrl";
       RfNotchArg.value = "false";
       RfNotchArg.name = "RfNotch Enable";
       RfNotchArg.description = "RF Notch Filter Control";
       RfNotchArg.type = SoapySDR::ArgInfo::BOOL;
       setArgs.push_back(RfNotchArg);


compile, install,start and is further weakened.

RX88MK2 arrived, so I am no longer worried about the problem with Sdrplay and SoapySSR.
 
Thanks for your help.

Wrong antenna or impedance for LW/MW?

I notoiced this before with the RSP1A and used an RSP2 with Hi-Z and a 9:1 balun, then the signals where high.

[9a7aof]

I have Dipole for 80m,

then profi antenna spliter.

Same antena is for OpenwebRX+ http://9a7aof.ddns.net:8074

and PhantomSDR+ http://9a7aof.ddns.net:8905


OpenwebRX+ have RSP1B and work fine for AM Broadcast, VDSL is very strong.

RSP1A and Soapysdr & Sdrplay driver, PhantomSDR+ ... Broadcasting station..nothing.

Miri driver and RSP1 clone work fine for AM Broadcast.

Thanks!

Beware, Soapy and SDRplay have 2 different API's.

The 3.0x can break Soapy and does support the RSP1B.

The 2.13 API works fine but doesn't support all/none functions of the RSP1B

It does support the RSP1A.

SDRplay made a mess of the API's....

As such Soapy has 2 SDRplay clients, depending on the API.

I stopped supporting SDRplay because of the 3.xx API that is a mess and buggy.

[Bas ON5HB]

My latest experiments....settings for the RSP1A UHF:

Code Select Expand

rx_sdr -f 435000000 -s 10000000 -d driver=sdrplay -g AGC=-20,IFGR=34,RFGR=1 -t rfnotch_ctrl=true,dabnotch_ctrlb=true -F CS16 - | ./build/spectrumserver --config config-rsp1a.toml

Using these RX_TOOLS fork, as it's better then the normal one:

https://github.com/askulysh/rx_tools.git

And this Soapy SDRplay driver:

https://github.com/pothosware/SoapySDRPlay2.git

I'm NOT using the 3.xx API or driver, as it's far to unstable for my taste.
