[Elecraft] K3 output stage high SWR - fault-finding?

Hi guys, I have a problem with my K3 reading 5.0:1 or more SWR on tune into a 50 ohm load. I was alerted to this problem when I could not get the same SWR my analyser was showing for a new antenna, and quickly discovered the K3 had developed a fault on all bands. The K3 shows a high SWR into a

Re: [Elecraft] K3 output stage high SWR - fault-finding?

The K3 shows a high SWR into a pure 50 ohm load or resonant antenna on both Ant 1 or Ant 2. I find that if I use an external SWR meter and connect the K3 to a dummy load through that, the SWR shows high on both the K3 and the SWR meter. An external SWR meter can not show a fault with the

Re: [Elecraft] K3 output stage high SWR - fault-finding?

Michael, Make sure the K3 ATU is in bypass mode, and check the SWR into your dummy load. It sounds to me as if you have the ATU in line when you are making this measurement. GL, Bruce, N1RX The K3 shows a high SWR into a pure 50 ohm load or resonant antenna on both Ant 1 or Ant 2.

Re: [Elecraft] K3 output stage high SWR - fault-finding?

Hi Joe, Bruce, Make sure the K3 ATU is in bypass mode Thanks for the tip. I had the same doubts but double checked for this. The ATU is bypassed. How have you checked the dummy load and patch lead? What convinces you that they are good? The usual stuff - continuity checks on the patch

Re: [Elecraft] SVGA worked for a while...

Hi Roger, I doubt this has anything to do with the firmware version. My first guess would be a problem with the RS-232 connection between the K3 and P3, but the fact that the center frequency readout is correct implies that the RS-232 must be working. It could still be intermittent I suppose.
