[aa5wg]

Has anyone tried any of these AM mods with their Drake equipment?  Which mod do you prefer and why?

My radio is the Drake TX4-C

Thanks for your help!

The mods Steve pointed out work very well. I modified my T4X 2 years ago. I am very pleased with the results. The only change I made to Chris and Tom's mod is to mount the carrier control pot in a small enclosure to make it easily accessable. (visible in the picture setting on top of the T4)

WD8BIL, W2NBC and all:

Nice looking station.  Thank you for the input.  I will study some more on this subject.

Anyone else have a comment that could help in deciding which circuit to choose?
