KPA500 Faulting on high SWR on power rise

john@kk9a.com
Great troubleshooting.  After a recent Elecraft post by K9YC I purchased
three of these
https://www.arraysolutions.com/surge-and-rf-protection/as-303u and I will
likely buy more as they look really nice.

Thanks Don, and everyone.
This morning, after reading the posts, I took an approach similar to what
Don is proposing.
I bypassed the surge protector, and voila, problem gone.
Now I have a new problem:  The Alpha Delta model TT3G50 is clearly marked
HP, but it's behaving like a 200W version.
The good news - that's an easier problem to solve.  Sometimes just being
able to discuss the issue helps one solve it.

Thanks everyone for all the help and support.

Be aware that the device on the page linked presents DC blocking to your
feed line, at least the schematic indicates that.

If you are running an RCS-4 remote coax switch, (or any coax switch that
runs control voltage down the coax), you will need to get a device which
passes DC, or change switch types.  This assumes you mount them at your
cable entrance point, and have the switch end beyond that point.

73s and thanks,
