Information for the Kenwood TH79A Dual Band Radio
My thanks goes out to the local library for the use of the
reading edge and
my wife Debbie for her help and patients, oh and lets not
forget Kenwood
for the nice manual. Don't know why they can't put there manuals
on the
web.
This is very rough so if you fix anything please shoot me
a copy. My
braille copy is a bit better except it has a few of my brailling
errors.
If you have any questions or need help in running your TH79A
just email me
I know this rig inside and out. If I don't know the answer
I'll try to
look it up for you.

starting

a frequency

longer
when the last digit is pressed. Since 440 is set to a 12.5
KC step,
you will not need to enter the last digit of the frequency.
For
example to enter a frequency of 441.875 you would enter 4187.
The
Th-79 has an auto offset mode however this only works on VHF.
For UHF
