I tried with another browser and still no luck.

@DSheirer
Anyway you can PM me a invitation to the group?

What does this mean?
"TUNER UNAVAILABLE - CHANNEL GRANT UNKNOWN SERVICE OPTIONS"
I am already running two sdr sticks. Do I need a third?f

I am monitoring Baltimore County P25 if that helps.

Thanks

what bandwidth do you have the tuners set for?

what bandwidth do you have the tuners set for?

Hmmm is this my bandwidth?
"Sample Rate [2400000.0] providing [96] channels at [25000.0] Hz each"
I did not know I could change it.

You will need 3 RTL-SDR's. At that sample rate, each covers ~2.4MHz of spectrum. The channels from the system you are monitoring spans 860.9625 - 854.0125 = 6.95MHz.

Should it be fine if I split one of the antennas to be used by two of the dongles?

I am not sure if I understand the question.

I have one antenna split and shared by 4 dongles with simple cable 1 to 2 splitters X 2. Individual mileage may vary but I don't see any determinable negative effect by doing so. The signals I use are pretty strong anyway for my purposes.

When conditions are right I trunk systems 62 km away - across water I admit.

Ok that was more what I was asking if it possible to split an antenna with 2 or more dongles.

Thanks
