[Elecraft] PR6-10/KXV3A Failure

[zumbruns]

I have the DIGOUT turned on for the bands that use the preamplifier (i.e. 6, 10 and 12 meter bands) so the preamplifier is on.  I hear it switch on when I push RX ANT switch.  I am only using the preamplifier on one radio at a time.  It works great in my old K3 but I can't get it to work on the other K3.  The 'other' K3 otherwise works fine with the P3, KAT500 and KPA500.
