You should really try looking on the site first...

However, seeing as you want the HTX10 info, which is somewhat different, I found this...

1.open radio look up on front face board if you look very carefully you will see 2 solder pads where there could of been 2 pins for a jumper plug you will see one side goes to a smd and the other goes to a ground island, solder a resistor of 10 ohms across the pads

Now put the radio back together and hold 'fun' and button 2 in while turning on.

The radio will have a 40 channel display on right of freq display 1-40

Press 2 to change bands along w/ lower left button'

THERE is NO fine mod for radio due to missing components.

Frequency Shift
1. Press the fine tune knob for "func" and then the shift button until shift+ or shift- are selected, as desired
2. Press "func" again and HOLD DOWN the shift button, a three digit number representing the shift will appear
3. Change the shift with the tuning knob
4. Key the mic to go back to normal mode



Transmit "shift"...
The radio has a transmit offset (shift) for repeater operation and it can also be used to work split frequency.
The amount of offset can be changed but it can only be changed in 10 KHz steps.


Fine tuning control
The Fine Tune control on the front panel effects TX and RX

No idea, I have never seen a HTX10, I have worked on a 485 though.

I found the above info after doing a quick search.
