Re: [Elecraft] vfos
Hold the Sub button and you'll see the UNLINK text appear in the VFOB display area. Hold it again anytime you want the two VFOs to track together. 73, Pete N4ZR Check out the Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com.

[Elecraft] vfos
I've done something weird with the K-3 vfos. On 15mtrs A and B are tracking together. B can be adjusted, but when A is turned, B moves too. How do I get them independent again?

Re: [Elecraft] vfos
Tom, You have the VFOs linked on 15 meters - it is a per band setting. Hold the SUB button to link/unlink the VFOs. Remember that a long hold (more than 2 seconds) will enter diversity mode. 73, Don W3FPR On 1/13/2014 3:50 PM, Tom Fitzpatrick wrote: I've done something weird with the K-3 vfos.

Re: [Elecraft] vfos
Hii Tom: You just need to “unlink” them by Holding the “Sub” button. I believe this is a band dependent setting. 73, Doug VE3MV On 2014-Jan-13, at 3:50 PM, Tom Fitzpatrick k4ie_...@yahoo.com wrote: I've done something weird with the K-3 vfos.

Hold the [SUB] button until you see UNLINK in the VFO B display. 73, ... Joe, W4TV On 1/13/2014 3:50 PM, Tom Fitzpatrick wrote: I've done something weird with the K-3 vfos.

[Elecraft] VFOs STUCK on 20m
Hi Everyone, I just completed doing the A-to-B upgrades on the RF board for K2 S/N 1599. The rig is about 5 years old and has run very well heretofore. In addition to the A-to-B upgrades, I also installed new RF and SSB firmware, added replacement crystals, and added the keying waveshape mod, VCO shielding, and thermal stability mods. As I was finishing up resetting the filters for the third or fourth time, I discovered that both VFOs A and B are STUCK at one place on the 20m band. Specifically, VFO A is stuck at 14100.00KHz and B is stuck at 14060.00KHz. Neither will change frequency. The LOCK button is not enabled, and all bands display the requested 5, 6, or 7 digits. Twenty meters is the ONLY band exhibiting this STUCK behavior. All others are perfectly normal. Both VFOs change as the VFO knob is turned on every other band except 20m. The STUCK 20m band VFOs also occur in all modes. Anyone have a suggestion for resetting/fixing whatever I might have dumb-thumbed so I can tune the 20m VFOs as I've always done? Just FYI the STUCK 20m VFO situation did not show up until about the 4th or 5th hour the rig was operating after all the mods were finished. Suggestions appreciated.

RE: [Elecraft] VFOs STUCK on 20m
Steve, You present a mystery. There is nothing that I can think of or see in the schematic that would cause the VFO to be stuck on only one band. The VFO lock is not something that is remembered across bands. Is there any chance that the K2 is going into transmit on 20 meters? If so, the K2 will not change frequency while transmiting, but that is just a guess, I cannot understand why it would be restricted to only one band unless you have a bad case of RF feedback on 20 meters. You might want to check the voltage at the left end of R30 for all bands (VCO Range in the K2 manual) to see if the voltage changes as you turn the VFO knob - if it does, then the VFO is tuning but the display is not reflecting the change - I don't know how that could happen but it would be informative. Try direct frequency entry for a frequency in the 20 meter band first - if you even consider doing a master reset, write down your filter and BFO settings before doing it because they will all restore to the default values. 73, Don W3FPR -Original Message- I just completed doing the A-to-B upgrades on the RF board for K2 S/N 1599.
