Kevin, That behavior is typical of a bad solder connection somewhere. I suggest removing the KXAT1 and installing the jumper - now what is the power output (you will have to use an external wattmeter) - operate it into a 50 ohm dummy load to eliminate the variables that may be introduced when operating into an antenna.
If the behavior continues when the back is put on, then the problem is on the main board - OTOH, if all works as normal, the problem is in the KXAT1. 73, Don W3FPR On 9/4/2011 9:12 PM, K Price wrote: > Don, > Thanks for the tips.
