Cobra 148 Repair SSB Tx warble


Cobra CB Radio MODEL(s):    148 GTL, 148 GTL ST, 148 NW ST

DESCRIPTION: Warble when transmitting on sideband.  This can occur if the power supply
cannot keep up with the power demands of the transmitter.

ACTION: Replace C172 with a 2200µF capacitor.


NOTES: If C172 is changed to 2200µF, it may make the radio more susceptible to
alternator noise.  For this reason change C172 only when necessary.  If alternator noise becomes a problem then install a filter on the alternator.
