Depends on the type of SDR and the specific site you are monitoring. You need to be able to cover the frequency ranges from the lowest frequency at the site to the highest. If you're referring to something like an RTL-SDR, they cover 2.4MHz and you will usually need 2 or 3 for most ARMER sites.

I have 3 going right now, but I have 3 more that I could use (total 6).
I doubt I will ever use all 6, but I have the 8 port Stridsberg and the jumpers already.
Probably add 1, maybe 2 more.
I just have to figure out the USB ports.
I have 7 total SDRs - 3 monitor ARMER, 2 monitor ALLETE Minnesota Power, couple more that rotate between various trunked system including Great River Energy, Brandon Communications, or Granite Electronics.

ARMER - depends on the day. I great best decodes from 2 sites, moderate decodes from 3 sites, poor decodes from another 2. Also, depends on what I want to monitor and which agencies.
