Re: Keying Relay Buffer Debate

I am in total agreement with that statement and
said as much to Palstar that perhaps the protection circuits were
too protective for the real world of antennas.? I also said
I didn't spend $3600 to laud how well the LA-1K performed into a
dummy load.
I'm confident that this will get fixed.? Palstar is a good
company.? These LDMOS amps just need further refinement.
When it does, I'll focus my energy on the SPE Expert 1.5K-FA which
has the exact same problem.

If the output devices in the LA-1K are rated for 64:1 SWR per
their spec sheet, why does the LA-1K not allow at least a 3:1 SWR
before faulting?? It could easily back the power off between 1.5:1
and 3:1 before going into fault.? ?It seems all SS amps are overly
cautious with SWR.
