KPA1500 - FAULT:LPF VMON

Hisashi T Fujinaka
What does this mean?

Other than that I can't transmit on FT8 right now? :)

I'm running KPA1500 MCU revision 02.09.

Hi Hisashi,

This usually means there is a fault with one of the control voltages in the amplifier.

I will follow up with you off list via direct email about diagnosing this further.

According to the fault table, LPF VMON isĀ  "incorrect bias voltages at
the TR switch".

I suggest you call or e-mail Elecraft Support with your concerns.
