SDRTrunk relies on "seeing" the entirety of a frequency spectrum so you'll often need more than 1 SDR if your frequency range extends beyond the 2.5mhz bandwidth of a cheap SDR. If you only use one SDR, Look into using DSD+ to listen to frequencies regardless of the 2.5mhz bandwidth of an SDR.

Let me check WV listings.

What county and towers are you trying to listen to on 460.1375 control channel?

If its the below listing then you would need 3 dongles for guaranteed coverage of all frequencies, could get by on two but may missed some traffic if system needs the 463.3625 channel. Also what is the ppm and gain set to?

Just knowing that Huntington covers a significant area with a lot of stuff going in Huntington, and knowing that submissions from that area don't occcur often, I suspect there are more frequencies active on that site. Every site has at least six freqs to begin with, and some have more depending upon loading.

WSIK813
453.125
453.35
453.500

WQCW253
460.1375
460.4125
460.4375
460.6375

WQRH759
461.225
463.3625
464.6125

That's 10 frequencies licensed. Five are listed in the Huntington DB entry. Even if just ONE more freq is active, the OP will be missing calls.

I have to agree that three RTL dongles are needed. Or an RTL Dongle (for the 453 freqs) and an Airspy mini (for the 460 freqs)
