[TenTec] RF Speech Processor

Gary is 100% correct if your objective is to work rare DX in a competitive environment. This can be configured as he describes with great success towards that end. 

  

Back in the 1970's one of my good friends and DX mentor who was, and is, a top DX'er around here (#1DXCC, Worked All Counties X4, Worked All Oblasts, high scores in the DX contests etc) ran a TR-7 with no on-board processor into two VOMAX RF processors in series (very similar to the TT 234 and today's digital 715) into a L4-B and then to a 4 element wide spaced 20m monobander at 75 feet. A big gun DX'er he was. 

  

It wasn't pretty sounding but there was no pileup of that era that he could not crack with more than three calls. None. 
I used to tell him that it sounded like "war" mode but it worked marvels for his DXing objective back then. 

  

My experience with the 715 using it with my Omni V.9, Corsair II and now my Omni VII is that it gives my signal the presence similar to having a 600 watt amp in line. And if I really need that contact, I occasionally use it in series with the rig's on-board SP with similar results to what Gary describes, being careful of how much of each to use. No tower, beam or linear  here and with #348 for DXCC..... It works.
