Thanks for posting these. Have not seen these mods...will keep these in mind. Just picked up a Drake TR4CW/RIT (noise blanker intact also!) as I steep in the world of Drake radios this Winter. After cursory clean-up, first off, the AM filter will be plopped in.... Jim KF2SY Title: Re: Drake TR-4 Mods Post by: Steve - WB3HUZ on November 28, 2006, 09:26:26 PM Good luck with the TR-4. Check the T-4 mods for changing to straight screen grid modulation vice controlled-carrier. I haven't looked at the schematics of the two radio, but I'd guess the modulation scheme is very similar.

Good luck. Hope to hear you on the air. http://www.amwindow.org/tech/htm/t4.htm |
