Quick question on the SDR changes. I'm using a Pi 5 with the starter load. My old SDR died, so I just bought a new RTL-SDR V4 device. If I run the calibration, I get a good -7 for initial PPM offset. When I try to run it on the GSM 850 band (I'm in Maryland), all I get are messages of:
[R82XX] PLL not locked!
[R82XX] PLL not locked!
[R82XX] PLL not locked!
[R82XX] PLL not locked!
[R82XX] PLL not locked!
for every channel.
The RTL-SDR website says that you need different drivers for the V4 model, but if you follow their Debian procedures, the SDR-VHF software in uninstalled. I've checked for the latest software, run apt, done the things I could think of. Is there something else that needs to be done, is this a bad SDR, any thoughts or suggestions?
