Ok, found enough connectors and adapter and will work on building up a set of identical cables to go from the amplifiers to the combiner. Looks like for now will be doing this with RG-58U but think I am under the limit running 500 watts on each.

Have all four Amplifier panels up and running now and discovered that when running in idle the amplifier with full complement develops way more heat then with just two amplifiers.  Harris wants the idle current set to 3.0 amps on each device to push them well into there linear range and that totals out to around 48 amps at 50 volts and the full complement of devices chug along at about 2,400 watts dissipation before you apply any drive!

Each device has its own bias pot that will allow you to set bias anywhere from just under three amps up to four but not any lower, short of changing the design of the bias networks looks like that’s what you get with the RF-1110B

Don’t know if I will have everything up for full power ops by Saturday for the RTTY net and may default to just running two panels like before, still have to fabricate the cables, change the output configuration to including the combiner and last but not least look at spurious and intermod.

Thanks to everyone who offered to help with adapters, cables and things.
