It is possible, I did convert a few of the 02 PLLs in years gone by,
I will look in my archives and see if I still have the instructions on
file, may take a few days tho'
I used to use the Electrophone CB and I think after the mods they could
cover a fair part of the 10m band.
Will get back to you.

Thanks H.

Email me. You can find my address on the usual site amateurs look up
addresses.
