Using the FX-series FM Transceiver Quick Reference Programming
Guide:
In addition to "pencil & paper math" calculation directions and also a handy
computer BASIC program for programming the FX- series Transceiver for
any frequency and transmit offset within its specified range, we provide this
guide for binary programming of a variety of popular Repeater frequency
pairs as well as some other frequencies of general interest. All binary
programming data for 512 through 1 presumes prior diode programming of
higher level binary inputs which remain constant for the 220 MHz amateur
radio band:
You'll notice definite patterns in the standard repeater frequency
assignments and their binary equivalents. Look at these patterns up and
down the programming input rows as well as across for any given frequency.
If your application could use more than the 12 channels easily programmed
for front panel switching, perhaps these patterns will give you some good
ideas for additional channel switching convenience.
