Many thanks Don, Good to know...the tx does ok at 12 watts, but when you turn the power up (hear the click), the power drops off to zero, and the swr disappear.
I have a good Collins wattmeter, that shows the 12 watts fine...but I do have a dummy load. I'll have one tomorrow and try doing a calibration with the utility. If it is the KPA3, I hope I can pull it and send just it to Elecraft. I'll call Monday about that. Many thanks for your help. 73, Grant, W5XB -----Original Message----- From: Don Wilhelm [mailto:[email protected]] Sent: Saturday, September 22, 2018 6:37 PM To: Grant Bright W5XB; [email protected] Subject: Re: [Elecraft] K3 PA3 not working Grant, Yes, the K3 uses the same power and SWR sensing for less than 12 watts and greater than 12 watts. It sounds like you have a non-functioning KPA3. You might want to check with an external wattmeter to be certain. 73, Don W3FPR On 9/22/2018 6:05 PM, Grant Bright W5XB wrote: > Hello All, > > Just received a new to me K3.
