Re: MTR2000 channel steering
Chris,
I'm trying to program channel steering in the RSS using GPIO pins on the 96-pin connector without any optional cards. That section of the RSS isn't very straightforward to me.

Re: Suggestions for service monitor
Mike,
This is a Windows program, but I think it's a lot of what you want and you can choose the hardware SATSAGEN ( https://www.albfer.com/en/2020/02/21/satsagen-2/ )

Re: Possibly Quintron PA? Need help identifying transistors
Well here's an idea, put 12 volts to it, put a service monitor or signal
generator into it, broadband watt meter on the output and sweep it and see
where you get a peak in RF out driving it with say
