Unlock the Clarifier
The mod is to unlock the clarifier. There is also another mod to prevent distortion from
front end overload from very strong signals. Here is how you do those mods:
When you modify the clarafier it will not track on the display (it will give you about 1.5 Khz shift either way) but you will find it useful in CB mode because the frequency cannot be adjusted. It is also usful when using the rig mobile. You don't have to keep pushing the SHIFT key. First, locate the wire harness that runs from the clarifier pot to the circuit board. Just in front of where it plugs into the board you will see R-197 (this resistor usually has wax on it). Clip the top of the resistor. Now get a 6" peice of wire and solder it to the stub of wire sticking out of the board (not to the top of the resistor itself). Connect the other end of the wire to pin 3 of IC6, pin 3 is the leg closest to the front of the radio. IC6 is is the 7808A regulator on the mike plug side of the unit case twards the front of the radio. Next locate D-59, just to the left of the clarifier harness. It is a 1N4148 diode. Cut the wire part of this diode to disable it. If realignment is necessary use L27 for AM, L28 for LSB and L29 for USB.

hey, just a question here. i have a 2950, and everything works great on it, but the receive, anyone even remotely close, barefoot or not, makes a roaring sound behind them, unless i cut the gain back 3/4 of the way. i tried looking for an agc control but found none on this radio, what am i to do? |

Is this a 2950 or dx ? Rangers are pron to overload and are losy on FM . My 2950 was so bad that when on 29.600 FM i could hear near by truckers on CH-19 i got rid if it replaced it with a HTX-10 ( the HAM ONLY ver of a MAG-257 ) and NEVER had the problem again. You can try several mods that out there like replacing diodes with shoky's it might help.
