TK-805 programming info.

Open up the radio top cover and move CN7 over (this is the jumper
closest to the front of the radio and to the right, see diagram below)
and turn on the radio. The display will now show you RX frequency
instead of channel, to tune fast (MHz) press the button that looks like
this -/\/- while turning the tuning knob, release to tune (KHz). To
switch to RX PL press the PTT on the Mic. once, then set the PL and
press PTT once, then set the TX freq. press PTT once and set TX PL then
press PTT once, this will start over at RX freq. only on CH 02, you can
keep repeating this all the way to CH16, if you press PTT on an empty
channel it skips to the next channel. For simplex, TX is the same as RX
and you can leave PL OFF on both if you wish, as the radio has an
automatic squelch.  To save your changes when complete, just keep
clicking the PTT (skip through any un-used channels) until the display
shows END, then just switch off the radio, move the jumper back, and
close 'er up! For those who want to really do a great mod, you can add
my little improvement.... When looking at the TOP of the radio, look at
the rear cooling fins on the antenna side, leave the outside one intact
and hack out the second fin with a dremel tool, leave the little
reinforcement tab at the very rear for obvious reasons. You'll now
notice a nice place to mount a small SPDT toggle switch from inside the
radio between the outside (first) fin and the third one, be careful
when drilling that area to prevent metal fragments from entering the
radio. Mount the switch, run three wires to the jumper pins of (CN7)
and close up the radio, you can now re-program anywhere with NO TOOLS!
You are doing these mods at your own risk of damage to your radio.
Don't perform ANY part of this modification unless you are comfortable
or experienced in doing so. DON'T EVER TRANSMIT OUTSIDE THE HAM
BANDS..... YOU'VE BEEN WARNED! I've performed this on both of my TK-805
radios and it works great.
