[TenTec] New Omni VII....first impressions

[Stuart Rohre]

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.
