K3 TX Gain troubles on 6m
Locked
 
|
I have emailed support but was curious if others have seen this issue.
I was seeing a few spikes on the KPA500 so I decided to do the TX Calibration. I have all the bands in good order except for 6m where the output will not go above 3.6 watts on the 5W calibration or above 48ish on the 50watt. I am going to try another cable and dummy load just for curiosity. -- Mike W0MU J6M CQ WW DX CW Contest 2011 J6/W0MU November 21 - December 1 2011 W0MU-1 CC Cluster w0mu.net ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Hi Mike...
Just to give you another data point, I have no problems doing the TX Cal on 6 meters. Using about a 6 foot length of RG-213 to an old Heath Cantenna. Works fine at both 5 watts and 50 watts. Good Luck... 73, Ken K3IU ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ On 11/8/2011 12:46 PM, W0MU Mike Fatchett wrote: > I have emailed support but was curious if others have seen this issue. > > I was seeing a few spikes on the KPA500 so I decided to do the TX > Calibration.

This was measured on the K3 doing the TX gain adjustment. It fails and
gives an error message.

Can you get it up to 50 watts doing the Tx Gain procedure manually on 6
meters?
