Here is another one that for the 'C' line is easier to perform. I've done both, with same results.

"Tim Kass" <[EMAIL PROTECTED]> made an utterence to the drakelist gang ---------------------------------------------------------------------- Hello Joe,
Well, I have been using my Drake T4X on AM for some time now, the mods are listed here....
www.wb4hfn.com/DrakeArticles/HiFi_AM_T4X.htm
The pot was a good idea rather than using a fixed resistor as I needed to adjust it to get it right. Too much and I got a "pumping" of audio and output, to little and there was not enough audio punch. I have it set around 20 watts out when I depress the microphone ptt.... Drake does not use the plate modulated scheme of the older AM rigs, so if you simply put in it in AM mode and talk, you will get that swing of Am output. This mod does a nice job, though not alot of output, but the sound is nice and I run it through a linear amplifier for about 200 watts carrier output. Hope that helps.

I have read a few AM mods that can be done to a stock T4XC.
Mine puts out less than 500 mw carrier with peaks to 100 watts. Audio is okay (not great).
What mods have you done to improve your AM performance? What issues have you run in to?
(Tubes are all new and radio was just aligned; mic is a D104).
Thanks!
Joe/N4ARI
