[Elecraft] KAT100 problems...

[Mike Sexsmith]

Hello all,

  I have a K2 setup (#4819) with the 100 watt tuner/amplifier in separate 
EC2 enclosure. Things have been FB for 3-4 months, but recently while using 
100 watts the tuner is unable to get below a 9.9 SWR on 80 meters, even 
though other bands tune fine. KAT100 Tuner also does not seem to remember 
tune settings anymore when returning to a previously tuned frequency. It 
will retune from scratch each time...  I rotated through the relays and all 
seem to click ok, although the relay for 80 m seems to sound slightly 
different...When using just the base K2 separated from EC2 the KAT2 internal 
tuner works fine and remembers settings. Board parts placement and 
solderwork appears ok.

   Is the relay itself the most likely culprit, or should I be looking at 
something else first?

Could someone please point me towards things to check in order of 
likelyhood? Thanks for any help!
