Here is some information about the TH-79A.
-----------
BAND LIMITS
-----------
VHF UHF
----------------------------------------------------------------------------
|RX = 87.240 ~ 135.995 AM | RX = 135.425 ~ 220.000 FM |

|TX = 136.000 - 179.995 FM | TX = 400.000 - 511.995 FM |
----------------------------------------------------------------------------

CURRENT DRAIN
-------------
The current drain for this radio is:
Rx no signal, dual band: 80 mA
Rx no signal, single band: 45 mA
Rx battery saver on, dual band: 20 mA
Tx HI power: VHF 1.3 A UHF 1.8 A
Tx LO power: VHF 0.6 A UHF 0.6 A
Tx EL power: VHF 0.3 A UHF 0.3 A
---------------
ADDITIONAL INFO
---------------
This unit scans at about 5 channels per second.
The Tx power at either end of the 440 band is about 0.5 Watts.
The power connecters on this radio are: 5.0 mm O.D.
2.1 mm I.D.
The sensitivity in these bands starts getting good around...
In band "A" the 440 side, at 403.000 MHz.
In band "B" the 440 side, at 418.050 MHz.

The coding used to program a TH-79A manually using DTMF tones in clone mode:
(note to geeks, I decoded this manually with nothing but a tape recorder and a dtmf generator!)
To program each memory channel of the TH-79A by cloning, enter the digits indicated
in the upper box. Where a # is, a box below it will indicate what digit(s) to enter.

| Tone frequency's |
---------------------
| 00 = 67.0 Hz | After tone number 26, you get frequencies above 250.3 Hz.
| 01 = 71.9 Hz | When I know what the exact frequencies are I will
| 02 = 74.4 Hz | include them in this file.
| 03 = 77.0 Hz |
| 04 = 79.7 Hz |
| 05 = 82.5 Hz | NOTE: When you are above 1750.0 Hz, the display dosn't show
| 06 = 85.4 Hz | what frequency the tone is.
| 07 = 88.5 Hz |
| 08 = 91.5 Hz |
| 09 = 94.8 Hz |
| 0A = 97.4 Hz |
| 0B = 100.0 Hz |

| 0* = 110.9 Hz |
| 0# = 114.8 Hz |
| 10 = 118.8 Hz |
| 11 = 123.0 Hz |
| 12 = 127.3 Hz |
| 13 = 131.8 Hz |
| 14 = 136.5 Hz |

| 20 = 210.7 Hz |
| 21 = 218.1 Hz |
| 22 = 225.7 Hz |
| 23 = 233.6 Hz |
| 24 = 241.8 Hz |
| 25 = 250.3 Hz |
| 26 = 1750.0 Hz |
|-------------------|
To program the ID data of each memory channel do this: To start ID programming send
twenty-one (21) *'s into your TH-79A. Next send a "D", then seven sets of two digit
ID data codes. Each set of two digit ID codes programs one
ID character. After each set of seven ID codes send a "D"
|-------------------| to start the next memory channel. To go on to the next
| ID Data Codes | memory channel simply send 7 more ID codes.
|-------------------| An example of cloning two memory channel's ID is in the
| 00 = | mod file for this radio.
