Robin,

I saw your email to me a few days ago, but was not able to respond 
because you sent it from Nabble and it did not put your email address in 
the TO: field - instead it substituted the nabble address and I am not 
subscribed there.

I strongly believe you have a problem in the bandpass filter - C32, C34 
or relay K6.

Examine the case of K6 first.  If it has any 'soldering iron scars', 
replace it.

If K6 is OK, then try setting the power at 1.5 watts and doing a TUNE 
with the K2 set to 18100 kHz.  Adjust C32 and C34 for the maximum power 
output.

If that does not cure your problem, then ask again (but not through Nabble).

73,
Don W3FPR
