Title: Drake T-4XC AM Transmitter Modification Post by: aa5wg on November 11, 2012, 10:36:11 PM 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! http://www.arrl.org/files/file/Technology/pdf/9411085.pdf Here is another mod. http://www.wb4hfn.com/DRAKE/DrakeArticles/HiFi_AM_T4X.htm And, http://www.wb4hfn.com/DRAKE/DrakeArticles/TechTips/T4X_AM_Modification.htm Or, http://www.ing.unitn.it/~fontana/HiFiAMT4XB.pdf And, http://www.ing.unitn.it/~fontana/TrueAMT4XB.pdf 73, Chuck Title: Re: Drake AM Transmitter Modification Post by: Steve - K4HX on November 11, 2012, 10:50:54 PM I know these are good.

Anyone else have a comment? Chuck Title: Re: Drake T-4XC AM Transmitter Modification Post by: WD8BIL on November 12, 2012, 03:46:19 PM 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)

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?
