Steve,
I have this working with my HL2 but I am using PowerSDR.? My amplifier and it's controller are homebrew.? The concept is the same,.you output CAT frequency data from Quisk and your amplifier should be able to read and parse the CAT frequency data.? The Quisk help file contains information on how to setup the output.? I would assume you should be able to find information on how to configure your amplifier.
