[Elecraft] P3 with transverters

[Dale Parfitt]

It has been since Fall that I have had  my K3 up on 1296MHz as we have been 
doing major landscaping around the dish (huge rock walls) and the dish had 
to be disconnected.
I finally got everything up and running for this evening's moon pass. The 
problem is the P3 shows no baseline signal and the waterfall is a blank pink 
screen. I can hear signals off the moon, and the P3 knows it is on 1296MHz 
as it is indicated on the top of the P3 display- but no spectral or 
waterfall regardless of the ref level. Same thing on the internal 2M 
transverter. Everything was working FB last Fall- of course there has been a 
pair of firmware upgrades since then. The P3 appears to function properly 
for perhaps 2 seconds then goes to no signals. CONFIG settings all appear 
correct to me.
Any ideas?

Tnx,
