Jerry, If you set the power to 40 watts as I asked, you should not have 120 watts output with TUNE. First you have to fix that power control problem. The most likely cause of that is the wattmeter diodes D16 and D17 in the KPA100. They are 1N5711 diodes, and you should order 4 of them so you

Good Morning Don: I did as you instructed.  On 40 meters the watt meter is reading 120 watts. I have 1 LED showing on the tuner.  The display on the K2 shows 52 wattsand 1.1-1  SWR As I change bands,  the results change.   The higher bands are showing less power out and SWR up to  1.5-1.. The

Jerry, There is no one transistor that will cause that behavior. First put an in-line wattmeter and a dummy load on the KAT100 ANT1 connector, set the power to 50 watts and then enter TUNE. 1) does the tuner tune so no LEDs are lit on the KAT100? If no, how many are lit? 2) what is the power

Good evening all: I'm looking for some advise.   My KAT100 / KPA100  are in an EC2 enclosure next to my K2. I was changing bands this evening and neglected to changeantenna's when moving from 80 to 40 meters. I hit the   " TUNE "   on the K2  and my KAT100  triedto tune.  It ran through the sca
