[Elecraft] VFO NR

[Detrick Merz]

Maybe you're pushing the wrong button. When I tried this myself, I first
tried to use the 'freq ent' button (because, after all, the radio tells you
'to unlock, hold freq for 3 sec' and that's the only 'freq' button I see).
But here's the trick: hold the RATE(KHZ) button. It should unlock. Don't
ask how I figured this out.

I forget what all (and expect someone else on the list will fill in), but
there were some updates made after those earlier serial numbers. I think
some of those updates can be applied to the older models, but not sure if
all can. I *am* curious to hear whether the VFO NR helps you or not, and
also curious to hear if your radio can be brought up to the current spec.
