I'm looking to setup 2 broadcastify feeds next time in the area for Ford Co sheriff and and Dodge City police. Last time I was back it looked like DC Police was using frequencies ~3 MHz above the control frequency which was over the bandwidth of a single rtl-sdr. If anyone is in the area and can provide some info for setting this up, it would be appreciated, I think I found the control frequency, but would like to confirm its not just some alt/secondary one since no one has actually marked them on radio reference yet. I would be using Raspberry Pis, RTL-SDR dongles (maybe?), and op25.
