KX3 troubles

A happy looking KX3
I decided to take the KX3 out and about on my day off Friday, it was an overcast day so I thought it wise to do my operating from the mobile rather than taking the bike. I set up the mobile whip antenna on my car and situated myself in the passenger seat and was ready to go.(note….this time before the trip out I made a list of things to bring so I was not without important items as happened in the past)  Brought the KX3 up to the 20m QRP watering hole (14.060) and just wanted to check the SWR on the radio before sending out my 5 watts of raw power. The KX3 gave me an error message but it seemed I was still able to transmit and I did for a short time. Then I noticed as I moved up and down the band my
Not so happy KX3
SWR stayed the same at 1.4:1 no matter where I was on the band….even up into the SSB portion. It was then determined something was wrong and I had a fast look at the antenna and coax but all seemed ok. I then switched to my 15m whip antenna and the error message was gone but I still had this strange low SWR across the 15m band as well. So it was time to pack things up and head home. Once at home I put the KX3 on a dummy load and tried it out and all was just the way it should be. I then put the rig on the MFJ 1788 loop and again no problems. So I suspect it's the mobile setup and I did post the problem on the Elecraft reflector and was given advice to check the mobile setup. When at home I did want to give the KX3 the full workout and to do so I started to call CQ on 20m. Terry WA0ITP came back to me from Iowa and our signals were in around 339 and conditions wee not that great but we were able to carry on a decent QSO. So the KX3 is working good but it's just another "project" I have on the burner that has to be worked out.  No time today as I am on call  this week and the phone has not stopped ringing with calls for me to go in!

    As with any device with a microprocessor in it, when in doubt, reboot first! 🙂 73, Larry

    Good evening Larry, it sure has been a road I have gone down many times with my PC and rigs as well.
