[Elecraft] Transverter question

I changed the heterodyne crystal in my old
MicroWave Modules 220-28 to use 27 MHz as the low
end IF. That way I can cover the whole 3 MHz of
the "new" 1¼M band from 222 to 225 MHz.
Admittedly, I have not yet tried it with my new
K3s, but with the original K3, Elecraft sent me a
program to allow transverter ( low level ) output
down into the chicken band.
The program may allow output down to 26 MHz which
may also solve the problem of the 4 MHz wide 2M
band.
I don't think the program would allow any
significant power output at 27 MHz, but it was
perfect for my needs. I sold my K3, so I need to
ask them again for that program so I can get my
new K3s working on the 220 ( I still call it that)
band.
As an aside, I don't think anything ever came of
that total guvmint fiasco where 220 to 222 was
taken out of HAM service but we were give some
space below 220 to use. (Bloody ridiculous) Now do
you see why many of us want them out of our lives
as much as possible?

I use DEMI transverters and they are capable
operating over 4-MHz on 2m. The issue is with the
K3 Tx power which falls off quickly above 30-MHz.
I am unable to have enough drive at 30.52 MHz to
get more than 5w out of my 50w transverter on
146.52-MHz.
One could install a second oscillator with a
118-MHz xtal to cover 146-148. The DEMI
transverter receives 144-148 because the K3 will
tune to 32 MHz in transverter mode. Apparently
the Elecraft transverter has a dual frequency LO.
