Joey -
You are absolutely correct. Any of the four line twins will work on all
WARC bands, simply by adding crystals for each band. The only
"odd-ball" is 30M, since it is so close to the PTO and IF frequencies in
the transmitter a "non-intuitive" crystal frequency is required, (20.8
MHz). There is a small "forbidden" range right at 5-6 MHz and 10.5-12
MHz for the same reason, but there are no bands affected other than the
oddball one at 5 MHz. These rules apply only to the transmitter.
Any other frequency range from 1.5 to 30 MHz can be added simply by
adding a crystal cut for 11.1 MHz above the bottom end of the desired
range, i.e, a crystal at 24.6 Mhz would cover from 13.5 - 14.0 MHz.

I am FAR from an expert, but what Geoff said about the twins isnt
Correct. I use mine on the WARC bands everyday. for about 40.00
for each band You can also, even cheaper if you dont run split.
all it takes is a set of crystals and tuning the radios by the Manual
for the band you want to use.
