Here are the instructions on HOW to program. http://www.fs.fed.us/fire/niicd/docs/vx ... d_prog.pdf
The info I found said the field programmer shorts pins 3 and 7 together to enter field programming mode. Additional info said to push and hold the PTT and LAMP when you power-up.
I have NOT looked at the schematic for this radio and I have no idea if this will work.
USE IT AT YOUR OWN RISK!!!
If it does work, please let me know and I'll add it to my "successful mods" notebook.

I haven't been here in awhile and just saw your post. I have sent you a PM with a couple questions.

Ok, I had this saved... I can't remember where it came from (here I think) but it is for the standard vx-900, not the USFS model because it is different and takes the instructions linked above. No mods are done to the standard model and the 'key' just shorts pin 3 and 7.
This is what the "key" does.

Specifics here, the front panel buttons don't do anything if you have them.Yes, there is a way to do field programming. You need to short pins 3 and 7 of the external mic connector, then hold down the lamp and PTT button while powering the radio on. You will see "FIELD" in the display. (The "lamp" button is the bottom button below PTT.) Pins 3 and 7 are the 2nd and 4th pin down on the left side as you are looking into the connector on the side of the radio.
Then using the channel knob, select the function you want to program, and using the top and side Set buttons change the entries. For frequency, use the toggle switch to select MHz, tenths, hundredths and the top/side set buttons to change the applicable item. (The side "set" button is the top button above the PTT, and the top "set" button is the orange button.) After changing an entry, turn the channel knob to another position to "enter" the change. Power the radio off and back on to go back to normal opesrating mode.
