Mike, if you have the very oldest D 104, the bad audio reports you describe
are typical of an impedance mismatched D104. It is a high impedance mike.
To use it for modern low to medium impedance SSB mike inputs, you need a
matching transformer, or an emitter follower preamp to step down the
impedance from the 100,000 ohm range to say 600 ohms. Then, the mike will
sound great. I use the D104 very successfully with Ten Tec rigs with
attention to matching.
