K3 Odd behavior
Locked
 
|
This morning I noticed something strange with #3539. On 80 & 160, tune only put out 10W. The level is set for 44W. Full output is 44W, power set to 100W. SWR with the AT in bypass is 1.3 on 80M, 1.2 on 160M. All this on ANT1. Power out on 40M & up is as expected.
I connected a dummy load to ANT2, and while screwing the connector on, there was a huge jump in the volume level on the 2nd receiver. The selected antenna is still ANT1. This condition is for all bands. The main receiver performs as expected, when ANT2 is selected, noise goes down. 73, Mike NF4L ______________________________________________________________ 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 Message delivered to [hidden email] |

I did a poor job on describing the noise level jump. If I switch to ANT2, the 2nd rec. level goes WAAAY up.

A TX cal seems to have taken care of the power issue.
