[Elecraft] XV432 Alignment Problems - Help!

[Don Wilhelm]

  Mark,

I am going to guess that you are plagued with the gremlin of 432 MHz 
energy getting back to the K60XV and interfering with its power 
measurement mechanism.

Plug the XV432 for high power input and drive it from the BNC on the K2 
until you get it aligned.
If all goes well when connected that way, put a 30 or 50 MHz low pass 
filter between the K60XV output and the transverter(s).  One of the 
little in-line Mini-Circuits filters works well.

73,
