Variable Power Board C-29

Variable Power Board used to set the dead key on Cobra 25, 29 and similar radios. The dead key or carrier can be set lower without loosing modulation and “trashing up” the signal. This small PC board is made to install inside the radio with instructions. A separate control (5K-20K ohm) can be installed to replace the Delta Tune with wires connected to the board at the marked holes. This way you can control the carrier from the front of the radio. This is a great way to match your Cobra to any low drive type linear amplifier.
