Calls - Multiple SDRs/systems on bcfy Pi image

[rattlerbb01]

Okay, so I am running a Pi4, and I have successfully been running both a stream and a calls node from the bcfy image for months now.

I applied for a second node for another nearby system/site. I am trying to configure the second SDR to work with this system, but I can't find anything good to show other examples of this in action. I have RTL SDRs, not airspy. I have made a separate config.json file for the second system, if that's the way, but I can't find out how to start a second trunk recorder instance within the shell sudo command window.

Any help would be appreciated as I haven't seen a thread on this, nor a good wiki or github link.

Well....it took some experimentation because the second calls node is for a new simulcast still in slow testing and rollout phase, and my signal is not the best. But I got it working just need to fix the antenna when I get home. Only so much you can do from RealVNC.

In case anyone else stumbles across this, here is my config.json file to make this work:
