Hi guys. I'm new to SDR tinkering and purchansed 2 RTL-SDR dongles with an 800Mhz tuned antenna between the 2 dongles. I've tried some of the software out there to try and setup the P25 system with little success. I found SDRtrunk the easiest to setup with my RR login info I was able to get up and running relatively fast. My question is while the setup works I see frequent errors advising no tuner available from time to time. Attached you can see the errors I'm receiving. Do I need a 3rd SDR dongle for the SRRCS P25 system?
