Bill, Normally there is greater than 12 watts output on 160 meters - most will do 15+. However, that is into a 50 ohm dummy load. The drive is usually plentiful on 160, and there is not really much you can do to increase it. You might modify the Transmit Buffer C150 value to get more gain on 160, but that would upset other bands too.
I suspect the input to your amp is not a 50 ohm load. If you have the KAT2, try doing a TUNE into the amp, or adjust the L and C manually with the ATU menu until you find a good combination. 73, Don W3FPR On 6/12/2012 12:11 PM, Bill W4ZV wrote: > Thanks to Don KI4D I finally got an N0SS T-R Relay kit for my K2.
