Texas Ranger 300-600-900 Series
TR-396F,
TR-696F Mobile, TR-696F SSB Base,
TR-936, TR-939WX, TR-966, TR-969WX

   Clarifier mod for TR-696, TR-966 and TR-696FSSB.

1. Remove R113 and D68.
2. Locate connectors J9 and J14, both connectors are located at the front edge of the main PCB.
3. Install a jumper wire from pin F1 of J9 to the pin labeled "8V" of J14.


Frequency Expansion
This one simple modification will work for all Texas Ranger 300-600-900 Series models.
1. Remove covers from radio.
2. On the main PCB, locate J33. (See below)
3. Locate wires on pins marked "P5"(yellow) & "P6"(grey).
4. Cut wire on "P5" (yellow) and install a SPST switch in line.
5. Cut wire on "P6" (grey) and install a SPST switch in line.

NOTE:Using two of the function switches available on the radio will eliminate the need for two new switches to be installed and mounted.
For example, on the TR-696F Mobile, if you do not need the CH19/OFF switch, simply wire it so that it is always off, and use this switch for P5. You can then do the same with Dim/Brt switch, wiring it so that the display is always bright, and use this switch for P6.


This modification will result in the following frequencies
(Lowest frequency = 26.695.......Highest frequency = 27.965)
