now reset and to use cross band repeat hold the "F" key for longer than 1 second, then press the "0"
key. The decimals in the displayed frequencies will flash indicating cross band repeat.

=============================================================================
EXPANDED FREQUENCY COVERAGE:
The TH-78a will receive far beyond its factory settings. It will also transmit outside its normal range to
some extent (of course that's not legal, now is it?). By removing diode D5 the frequency tuning will be
expanded. New ranges include:
121-170 MHz transmit and receive
•
400-500 MHz transmit and receive
•
300-399 MHz receive and 800-999 MHz receive only
•
To get 300 & 800 MHz coverage, place the TH-78a in VFO mode. Press the "F" key for longer than one
second, then press the "BAND" button. The sensitivity of the radio is not good in the 800-999 MHz
range. I have not tested it personally yet, but rumor has it that it's pretty bad.

CLONING:
The TH-78a can be cloned without cloning cables or special equipment. This "cloning" will allow the
entire contents of the memory to be transmitted and stored in another TH-78a. The TH-78a cloning
procedure is accomplished over air with the two TH-78a units on the same frequency. Placing them side
by side on a simplex frequency is best but you can clone over a repeater (if you don't time it out or make
the owner mad) if desired. This "undocumented" feature can be of great use if fleets of radios are
purchased for clubs or user groups and all need similar programming. It's important to keep in mind
that with the ME-1 memory expansion module installed the cloning can take up to an hour. Your best
move is to use 2 dummy loads side by side.
PROCEEDURE:
(1) Both radios must be on the same frequency.
(2) Activate both radios by pressing the "0" key while turning the power on. The lower radio
displays will read "CLONE".
(3) Now, click the PTT of the "master" radio. The radio will transmit on the selected frequency in
the "economy low" power mode. You will hear the DTMF (Dual Tone Multiple Frequency) touch
tones come out of the speaker as the radio transmits the contents of its memory. The full
transfer will take about 4 minutes for fifty channels. When the data has been transferred, both
radios will revert back to the original frequency.
(4) Turn both radios off, and then on again. They will now operate normally and the memory
contents of both radios will be the same.
