[Milsurplus] TCS

[Scott Johnson]

The RS-38 was also a standard civil general aviation and large aircraft 
standby mic up through the mid sixties.  It is as reliable as a WeCo 
handset mic, but with radios such as the TCS, there just isn't quite 
enough gain in the audio chain. I am surprised at Collins for not 
employing at least one gain stage in front of the modulators.  Even the 
BC-375 had a triode gain stage!
