Cobra 200GTL Increasing the microphone gain

Share

Cobra 200GTL

Modulation may be low with some noise canceling microphones.

ACTION: If modulation is low with an aftermarket microphone, then change R178 and R182 to 82Kohm.

See images for the location of R178 and R182.

ADJUSTMENTS: None.

NOTES: It may be easier to access the resistors if you temporarily remove C147.

If at some later date a different microphone is used (one with a higher audio output), it may be necessary to turn down the Mic Gain.
