I think its normal if you run them into the typical 1 meg input resistance most rigs had. At 1 meg and lower, they sound like a cheap telephone or worse. They can sound real nice at 5 meg.
Found this out with mine years ago when it first hit the airwaves. Happened to work Ed WA3PUN and the gang out that way late one night, and was informed of what was wrong ad exactly what was needed. Ed even sent me a schematic with the necessary changes. Changed out said input resistor in my transmitter to a 4.7 meg I had on hand and it made a world of difference. Brian and Paul have both made recordings of me and to my ears, it sounds just like me. As others have mentioned, you need a crystal element and it needs to be good. They're not terribly fragile per say, but are susceptible to heat (being left in the bright sunlight coming in a window will do it) and very much so to being dropped or knocked over. A mic can look brand new but sound like absolute dung if it's been dropped. Definitely bypass the internal amp, if it has one. The ceramic D-104 in the pile here has a green tag affixed to the top. That's how I always told them apart. As far as testing, I've always used a known good head for comparison, and just swapped them out to test. Difficult to do in it's your only mic, of course. Keep in mind too, that even a good D-104 crystal will sound a bit peaky, which is what they are known and appreciated for. You won't get thundering lows out of it like you might using the RE-20 and processing. But it's tough to beat a good D-104 for an off-the-shelf mic with decent audio. A good one makes an excellent standard for comparing the audio of other mics. ~ Todd KA1KAQ ______________________________________________________________ AMRadio mailing list List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected]
