[Hammarlund] Re Original Mike For HW-202

[joel hallas]

Duane,

I no longer have my HW-202, nor the docs, but can say that it came with 
a high-Z crystal mic that would also work with the HW-101 I had. It was 
not amplified, just a crystal element.

There is likely a deviation or gain control in there and one possibility 
would be that a previous owner used an amplified mic and reduced the 
gain to compensate.

I would also check for mic lead connectivity since the wires often break 
(25 years old?).

GL and 73, Joel W1ZR
