[Drake] TR7 Speech Processor

[W2WU]

To my knowledge Drake never offered an  internal speech processor for the
TR7, nor is it in my service manual or sales liturature.

A periodical offered a generic speech processor project.  I built and used
that processor with the TR7. It did not substanitially increase readability
or provide "punch." The TR 7 provided execellent audio when using a
microphone of corrent impedance and frequency response.

Try a different microphone. The Shure 444 is an aftermarket microphone
tailored to SSB applications. It can be wired for low or high impedance. 73,

Hello,

Does anyone have any information on an INTERNAL speech processor for the
TR7?  I am trying to determine if Drake or an outside firm ever made an
internal unit because I have seen a radio advertised with one and have never
heard of it.  I am only familiar with the EXTERNAL SP75.

Any help is appreciated.

John
