[Elecraft] KRC-2 Possible Lightning Failure

[Brian F. Wruble]

Hi all:

I have had my K-Line (K3, KPA500, KAT500, P3) all working brilliantly, both
local and remote using my new K3/0 Mini.

While I was away, a severe electrical storm passed through the QTH in
Maryland.  I returned, moved cables around to get local operations geared
up.  The KRC-2 band decoder seems to have failed.

I have 5 volts after the voltage regulator, U3, but I cannot get 12V at any
of the "high side" driver outputs on J6, J7, J8 and J9.

The unit communicates with the configuration program, and I have firmware
version 1.6.  I have re-loaded the firmware.

What should I try next?

Tnx es 73 de Brian W3BW
