[Elecraft] No XMIT on 6 meters

[John]

There has been some chatter here lately about 6 meters not working. I 
thought I would try and duplicate some of the problems. Well I 
couldn't. However, I did find a problem with my  K3 #501 on 6 meters.

I don't have power pwr output on 6M. Perhaps  I didn't check before, 
or maybe I didn't run the 5 watt cal on 6M. So, I ran the cal, all 
bands are fine, 5 watts, except 6M, where I get 1W and a ERR TXG msg. 
I don't hear much background noise on receive, with an antenna 
connected.  May be a BP filter issue? The Ops manual says to hit the 
service manual, not encouraging. I really don't want to ship the rig 
back to Aptos, it's already been sent back once. When it was returned 
to me, I was told it met all spec's now.  BTW, I haven't had the 
cover off the radio since it was returned.

Any ideas out there?
