Hi, gang!
I went on to the 7238 Drake Pre-net this afternoon and strange things were happening.? I heard some noise in the speaker when the PTT was pressed and WB0IQK said that I sounded excessively tinny.? I was fortunate to have my $10 GE-branded Shure 444, which worked like a charm but, of course, I want to know what is wrong with the 7077, so I took it apart.
Oy, vey!? What a mess inside!? Someone had put in a couple of capacitors (low value) and what looks like a transformer.? It's all kludged in there, so I know this ain't no factory job!? Lots of lousy workmanship and electrical tape trying to hold things together!
The mic element I can't be sure if it's correct, though it looks like it all fits together like it should.? The mic element measures around 430 ohms on my Fluke 77.
Is this simply a case of the wrong element in this mic?? The TR7 manual specifies a high Z mic.? I am tempted to simply get a Heil element for high Z and being done with it.
If any of you have a 7077 mic, can you measure resistance across the mic element for me?? This should be from ground to pin 1 of the mic plug.
TNX & 73,
