I am going to disagree on this John... I talked with the engineer at Astatic
years ago when Astatic was a real ham radio company... He said " The preamp
is to make the terrible new crystal elements sound good" He also said that
since the mid 80's you cannot find an element that will really make the
d-104 sound great. Now to the end of a great sounding preamp better then the
astatic preamp K7DYY up in Seattle has made in my book the best sounding
D104 pre that I have ever heard ... I have one and I love it.  Just my
nickels worth...I have been an Astatic dealer since the 80's and not any
longer. In my business now I use all Shure and Heil...

Very Best 73's

What's there to modify?  Just bypass the dumb preamp and use the Hi-Z 
crystal directly into your Hi-Z input speech amp and you have a GREAT 
AM mic!

I've lost the call and email address of the ham who modifies the D-104 
for
better AM audio.  Can anyone share, please?
