Well war-story time.
While running the MARS station in Berlin back in the early 70's, I had an
S-Line with 30S1 linear, and a 204BA on top of a 75 ft. tower.
For lack of a speech processor (and no knowledge of them), I devised my own $5
solution.
I inserted a plastic funnel into 3 ft. of rubber garden hose, with a $3 radio
shack xtal mic duct-taped to the other end.
It gave me just a slight bit of echo.
The standard procedure was to break pileups (BIG DX-Peditions) with one single
"This is DOG LOG FOUR QUICK FOX".
I don't recall a single time of needing to call a second time.
In retrospect and in light of what Bob just posted, I guess I was a bad guy,
but I sure got a lot of reports of "over-riding everybody". Other adjectives
used were "strange", "weird", and "interesting" signal.

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.
