[Elecraft] [K3] Reconfiguring band boundaries

[Thomas Horsten]

Hi,

I sent a question about this to Elecraft support, but I didn't get a
reply so let me try the community..

I've got a K3, serial no. 4208, and I would like to change it's band
settings so that it will match my UK licence. Currently, the "band
end" limitations are not correct for my region.

For example, it will transmit on the section of the 80m band above
3800 that's not allocated in the UK, and the same for 40m at 7200 and
above.

So I'd like to change the band limitations to lock the unallocated
sections out and avoid accidentally transmitting outside the licenced
bands. For example, I sometimes hit "TUNE" and scan up and down the
band to make sure that the SWR is reasonable across the entire band,
in this mode the VFO isn't displayed, but if I hit a programmed-in
band limit it stops by itself, but this doesn't prevent me from
transmitting out-of-band at 40m and 80m for example, because the upper
limit is not correct for my location and licence.

Is there a way to reprogram this? It seems to me it should be a simple
firmware tweak.

Any help/pointers would be appreciated!
