RTLSDR V3 Dongle for mobile DAB reception

Post by MS71 » Fri Oct 05, 2018 1:45 pm

Hi,
I like to use a RTLSDR V3 (R820T2) dongle for mobile DAB reception.

Starting from https://github.com/steve-m/librtlsdr.git:
* I enabled the BIAS TEE for supporting my active antenna
* I enabled the VAGC for having a quick AGC
=> So far, this is working.

Additional, I like to measure the current RF field strength.
Because the automatic AGC is used, I have no current/software gain value.

In http://superkuh.com/R820T2_Register_Description.pdf, I found the register
0x03/RF_INDICATOR[7:0], but this value is allways 0xff. Any hint for enabling this register?
Any hint for getting the current VAGC gain?

Thanks

Maik
