Broadcastify Calls and multiple systems/counties

[iceman977th]

I want to experiment with setting up Calls so I can capture each channel individually. One county is mostly P25 conventional with a couple analog channels, and the other is analog only, all VHF. Spread is about 8-9MHz on the frequencies to capture. The two biggest question I have are:

1. I know the standard RTL SDR's can only capture about 2.4MHz per device, is it possible to use multiple to cover the bandwith needed?
2. Is it possible to use the same set of SDR's to capture two different counties and put them into two separate systems?
3. How powerful of a PC am I looking at to do this? Would a Pi 4 4-8GB have enough HP to handle this or should I look at a better dedicated system?

I am able to have 7 conventional analog frequencies on a RPi 4 before it overloads at 8 frequencies BUT all of the frequencies are within 1 MHz of spectrum. It is my understanding that spectrum is what eats up the HP so if you need all 2.4 MHz maybe you can only have a couple of analog frequencies on the RPi 4 before in overloads? I don’t know about conventional P25 or trunked systems to give you answer on those questions.
