Hi I have a Texas Ranger 6900F JUMBO and a new style Connex 4800DXL, the one with echo. I want to tie together the transmit and receive on the clarifier. I've done it on other radios. I can't find the mod anywhere though. If anyone could help me out I'd appreciate it. 73'S QPER 222

Sharing the clarifier mods with other Copper members would be nice.

Jon,

In the above post from Wareagle he said it was the same for the Cobra 148 GTL-DX.

Not sure if this is correct as it is for the OLDER 148 GTL-DX.

Clarifier Modification:

#1 ~ Remove D84

#2 ~ Remove the Blue wire from the FINE Tune control and PC board.

#3 ~ Run a New wire from from where the Blue wire was on the Fine Clarifier control to cathode of D-88 (located directly in front of Green A-473 Power Transistor on right side of Chassis.)

#4 ~ For more "Down Slide" pull OUT R-232 and install a wire jumper in it's place. This will give you about 12KC down slide.

NOTE!

If you like the FINE CLARIFIER SKIP step's 1 ~ 3.

Hope this help's.

Lon

Qper, Connex 4800 DXL and all RCI 6900 *** " C " boards. Remove D68. Remove R 113. Add a jumper from the " Right side " of R 113 to 8 volts. I will attempt to upload a .jpg showing the jumper, although I ran the jumper straight to the regulator chip. Worked great on mine. 73, Fred AB5AZ
