Re: [Elecraft] K3 Erratic VFO behaviour, Switching bands and freq's

Pete, This is very baffling, and is most likely firmware issue. I'll discuss it with customer support right away and will be getting back to you with some questions. 73, Wayne N6KR On Sep 23, 2016, at 12:32 AM, G0PNM wrote: > So, the USB/Serial cable arrived

Re: [Elecraft] K3 Erratic VFO behaviour, Switching bands and freq's

So, the USB/Serial cable arrived yesterday. Last night, I downloaded the Utility software and reinstalled the firmware 5.50. All was good, no issues. So I decided to try the Beta firmware 5.52 and again no problems and the radio behaved normally so I was overjoyed. I sent an email to Elecraft,

Re: [Elecraft] K3 Erratic VFO behaviour, Switching bands and freq's

Hello Pete A few months ago I had similar problem with my K3 (sn: 05845). I upgraded the FW from 05.29 to 05.38, tuning the vfo, the freq would jump, sometimes out of band. One occasion both vfo's read 300.000.00. The rig had worked fine on the old FW so I reverted back to FW 05.29. That

Re: [Elecraft] K3 Erratic VFO behaviour, Switching bands and freq's

Mark makes an excellent point but a special anti-static pad is not required for a simple procedure like this. However, simply unplugging and replacing the FP does not require touching anything inside the K3, so there's no danger. If you need to touch the pins on the connectors or anything inside

ct: Re: [Elecraft] K3 Erratic VFO behaviour, Switching bands and freq's Guy is quite right about the pin issue, however I have an early K3 with the original pins and it works FB after 9 years. To be absolutely sure it isn't something external to the K3, first I'd disconnect EVERYTHING except the main

Re: [Elecraft] K3 Erratic VFO behaviour, Switching bands and freq's

In the K3 there are a few digital lines from the front panel which carry multiplexed information to the CPU. The only way I can think of that would scramble unrelated front panel input according to your report is that the multiplexed line is malfunctioning and screwing up the data stream into the

[Elecraft] K3 Erratic VFO behaviour, Switching bands and freq's

Hi all, New to the whole Elecraft scene. Just acquired my first K3 and its serial number is 07126. I have been experiencing some strange behavior while rotating the VFO whereby the radio would change bands unexpectedly. On occasions, the rig will jump to a supposed frequency well out of the
