Weird problem, just switched to 15M and decided to tune around and see
if there was any openings when my VFO on 15M locked up. When I switched to 15, it was on 21.070 and as I spun the dial up it stopped on 21.100 and wouldn't change in either direction. Both the display and VFO appear to be locked on this band as the frequency doesn't change as I spin the VFO. Direct frequency entry appears to work but as soon as I touch the dial it jumps back to 21.100. All other bands are working fine, this is only a 15M problem. Any ideas?

JT,
Those symptoms could indicate that the 15 meter entries in the EEPROM have been corrupted. Try running CAL PLL before doing anything else - don't forget to plug the frequency counter into TP1 and switch to 40 meters. If CAL PLL does not correct it, record all your menu entries and try a master reset - then run CAL PLL and use CAL FIL to re-do the filter and BFO settings. There are just no hardware problems that I know of which could cause that behavior on only one band - all bands, then yes it would likely be a hardware problem, but not a VFO failure to tune on one band. 73, Don W3FPR JT Croteau wrote: > Weird problem, just switched to 15M and decided to tune around and see > if there was any openings when my VFO on 15M locked up.

> Did you accidentally press the LOCK button? Negative. It is one of the first things I checked. I'm going to try doing a CAL PLL like FPR suggested. Hopefully I won't have to do a master reset as I finally have all my CW, SSB, and RTTY filters just the way I want them. -- JT Croteau, N1ESE - Manchester, NH (FN42gx) _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Well, CAL PLL alone did not work. I had to do a master reset.
Now to put all my settings back...
