So recently, I purchased a Raspberry Bi 4B, I loaded on the lastest build. I purchased an additional RTL-SDR.com blog tuner to use, with the intentions of making it a public SDR on the SpyServer Network. My issue is that it connects to the network, but its 'unavailable". I followed all the instructions, but I am hitting a brick wall and don't know where to turn. I keep getting the error "[R82XX] PLL not locked!". The tuner works good in GQRX, I'm just having issues with getting it to work as a SpyServer. Any help would be much appreciated.
