[TenTec] D-104

[Dr. Gerald N. Johnson, P.E.]

Purchase and install a Shure R-5 element. Its a communications element
with less response outside the transmit filters and makes a better radio
system than the D-104 with its rising characteristic ever did. In some
SSB radios the D-104 actually overdrives the transmit audio and balanced
mixer with pitches that are outside the transmit filter and so leads to
difficult to cure distortion. I'm using an R-5 in my D-104 case, have
for a couple decades on S-line and now on Corsair II and the audio
reports are superb.

73, Jerry, K0CQ
