[Racal] New to RACAL list looking for VLF EPROMS RA6790/GM

Hi Craig,

There are several versions out there. Often you trade out one option on the
radio for another one. For instance you may pick up low frequency coverage
and loose a factor of 10 on your smallest tuning step.

There is a way to "fake" a 6790 into running below 500 KHz. As I recall it
involves entering a partial frequency from the keyboard. The advantage is
that it lets you try things out without changing out the rom's.

If your radios work like mine they are pretty darn dead below about 400 KHz
or so.

    Take Care!
