Right. But FIRST set TXEQ to max cut for the first three bands, 6 dB cut 
on the 4th band, 3 dB boost on 2.4 kHz, 6 dB boost the top band (3.2 
kHz). Then set COMP as Bob described. The TXEQ settings prevent wasting 
transmitter power with speech components that don't contribute to speech 
intelligibility. This was learned by AT%T Bell Labs nearly a century ago.

OK, with mic set to 20 ALC was a little low; 23 setting produced ALC=5 
with speaking the word "FORE" (old radioman's test word for checking 
modulation).


When I advanced COMP, 23 now has 10-dB indicating.  MY guess the 
difference heard by others from 20&25 to 23&23 probably would not be 
discerned.  I will find out tomorrow during our VHF Net.  My old default 
settings were 20&20.

Re: [Elecraft] The RIGHT way is to adjust COMP

2022-06-30 Thread Walter Underwood 
Seven years ago, I collected advice on setting TX EQ and compression from this 
list and compiled it into a blog post. This uses the DVR to A/B test 
compression settings to get the highest level that does not cause artifacts on 
your voice. The article says “KX3”, but the procedure is the same for the K3. 
Most of the advice came from K3 operators. The idea to use the DVR is from Lyle 
Johnson, KK7P.

[Elecraft] The RIGHT way is to adjust COMP

2022-06-30 Thread Bob McGraw 
Start with COMP at 0, adjust the MIC gain while speaking normal voice to 
attain 5 to 6 bars {no more} as indicated on the ALC meter.  Then adjust 
the COMP for a value to indicate about 10 on voice peaks.


For those that believe in using the "I turned it up a little bit, now 
how does that sound?" approach, . forget it.  Set it correctly as 
described above  and it will sound great.   There is a right way to do 
this.   Anything else is flying by the seat of your pants.


If you desire to have it sound different, then twiddle the EQ values 
until your hearts content.   After doing so, you may need to reset the 
MIC and COMP levels to be correct.


I much prefer to listen to my signal on a remote SDR and record my 
signal on the SDR site. Then listen to it in my shack on my speakers.  
Then I know HOW MY SIGNAL SOUNDS.   That's what is important.   I make 
adjustments from there.


As to others, they can adjust their receivers, their speakers, their 
hearing aids and a host of other things that will make ones signal 
sound..err, many different ways.  So which one of the "many 
different ways" is best?  Likely none of them.

The RIGHT way is to adjust COMP for a METER reading of 10 dB on voice
peaks.
