Drake Mods - T4 Transmitters

Authored by VE3EFJ


    All of the Drake 4 line will transceive amongst themselves. Between the T4X and the T4C there was little difference. Most of the changes in the T4C from even the T4X were cosmetic or for better operator convenience. The B series used neon bulbs to indicate the active PTO when set up for transceive; the C line turned the dial lights on and off.

    A properly working T4any will give about 150 watts output on 80 meters, dropping to 80 or 90 watts on 10. The audio should be really clean and with properly operating ALC you should not be able overdrive the finals. There should be LOTS of drive on all bands.
