fm-radio

fm-radio is a fork of the radio module, however this is made with the focus of FM receiving, for example, here RDS is better as now it decodes:

• PTYN
• AF
• ODA
• TP
• TA
• ECC
• LPS
• ERT
• CT
• ERT this is just the best RDS demodulator for SDRs, i believe better than RDS Spy, that doesn't do ERT

How to install?

Well, you have to compile it yourself, first you need to be able to compile SDR++ in the first place (tip: you can disable all of the modules in the CMakeLists.txt file to speed it up)

After compiling you'll need to cd into your decoder_modules folder and clone there this repository, so:

cd decoder_modules
git clone https://github.com/KubaPro010/fm_radio

After that you'll need to edit the CMakeLists.txt (again maybe) in the decoder modules group add the line option(OPT_BUILD_FM_RADIO "FM Radio" ON) thne click on one of these OPT_BUILD things, specifically OPT_BUILD_RADIO, now find a 2nd occurence of that and you'll see something like this:

if (OPT_BUILD_RADIO)
add_subdirectory("decoder_modules/radio")
endif (OPT_BUILD_RADIO)

Under it just paste in this:

if (OPT_BUILD_FM_RADIO)
add_subdirectory("decoder_modules/fm_radio")
endif (OPT_BUILD_FM_RADIO)

then just do the build instructions of sdrpp and you should have the receiver compiled
