[Elecraft] D-104, only slightly OT

[Ron D'Eau Claire]

Do you have an audio amplifier, a mic input on your sound card or even a
pair of headphones around? Try the mic with them. Any audio in the phones is
likely very low level but you might hear something in the typical 50-ohm
"computer" or "game" headsets around today. Some clip leads and a suitable
connector are all you need -- ground and hot lead -- to whatever 

If you have an o'scope, it'll show audio too. 

(Of course you have to make noise near the element ;-)

If you hear or see *any* response from the element, it's likely good. Those
old crystal and ceramic elements tended to work fine or not at all. 

Be sure the amp in the base has a good battery in it: 9V IIRC.

Good morning,
 
I have an old D-104 that worked fine when last used (1977) and want to use
it with the K2.
 
I know I could replace the element with one from Heil, but I would prefer to
keep it as original as possible (it does have the preamp in the G stand
base).
 
I will assume the preamp works, and I know the K2 works, but I'm not so sure
about the original element in the mic.  
 
Does anyone know a way to test the element before wiring it up?
 
Thanks es 73,
 
Tom, NG3V
