[Elecraft] K3 6M problem

[James C. Hall, MD]

No the ATU is in bypass and the correct antenna is selected. In fact, trying
to use the antenna tuner on the 6M antenna was fruitless. As I seem to
recall, the ATU does not work on this band.

Subject: [Elecraft] K3 6M problem

Hello:

 

After returning my K3 back to the shack after Field Day, I have discovered
that 6M no longer transmits with low SWR. I checked all the rear panel
connections as it is interfaced through a microham MK2R+ and Stationmaster
band decoder. However, I have the 6M antenna coax directly going to Antenna
2 on the radio. Using an antenna analyzer, the antenna shows excellent SWR.
Using a dummy load to each antenna port, all bands shows good SWR except 6M.
I updated the firmware and cycled the power but I still have the HI SWR
showing with 6M.

 

I do have the PR6 pre-amp in line, but the problem is not receive.

 

I'm stumped. Any help appreciated.
