Offered for sale is an extremely rare DX Engineering LC-2-TR Speech processor for the Drake line of transceivers.
The function of the DX Engineering Speech Processor is to increase the average power of a SSB voice signal while keeping the peak amplitude constant. It typically provides 6 db or more increase in average power while maintaining normal intelligibilty.
This version of the DX Engineering Speech Processor (versions were made for other radios including Collins) is for the Drake line - TR-3, TR-4, TR-4C, and TR-6 radios.
It is in excellent physical condition. I have no way to test the electrical condition, but it appears to be unused. It comes with what you see in the photo, and the the original 9 page manual.
I'm asking $240, shipped to CONUS via Priority Mail. OBO
