Compression with Speech Processor-Low Meter Reading
Problem: "What is happening is that I can
get good ALC on SSB, but very little compression reading on the meter. The PROC
is turned all the way up and the PROC LET is on, but I get very little COMP
reading on the meter. The mike gain is at 9 o'clock."
Comments and Suggestions: Be careful! More
than a few DB of compression will bring up the background noise in the shack
(blowers, kids, dogs) and you'll be making your own QRM. The object should be
more readability (and hopefully quality) at the other end, not just higher meter
readings. Listen to any SSB DX contest to hear what over-use will do. VE7XF
Processors bring up the average power level very quickly and need only be set
slightly to improve the average power. Audio gets real nasty real quickly when
any processor is much higher than just being tickled. I run mic gain at 9:30 I
run the processor at 9:30 With the Heil Gold Line equals Fantastic Audio KB6GKC
Years ago I read an article by ON4UN on speech processing, and his 'test' was to
be able to run 1400 watts OUT and the wattmeter NOT show more than 2-3 watts or
so ... I took that one step further and with 1500w out, the wattmeter sits still
on the ZERO peg when I am not speaking ... I also use AL1200 amps here, which
have very noisy blowers, so the addition of the W2IHY units has helped to ensure
that when I am S9+20, the background is NOT S9+10 ! Just as a data point ... on
the MPs here ... MIC is at 9 o clock, the PROC is at 12:45, and the mikes are
