Elecraft] KX3; Procedure for Setting TX CMP & TX EQ + DVR

[jkiracofe51]

        I desire to utilize both CMP and TX EQ in SSB transmissions on a KX3.


        In the KX3 Owners  Manual, there are well defined procedures for
setting Mic Gain, CMP and TX EQ, but it leaves doubt as to which to
set first as Mic Gain and CMP are grouped together with TX EQ
described several pages later. This would imply TX EQ would be set
last.

        As TX EQ could effect overall audio amplitude peaks, it would seem
that TX EQ should be set first then adjust Mic Gain for proper levels,
then set CMP.

        What is the Elecraft recommended procedure / order  for setting these
three adjustments ?

        My next questions involves storing and playing messages on the DVR
where CMP and TX EQ are desired.

        With Mic Gain, CMP and TX EQ set as desired for a CQ message for
example, would the DVR store the message as processed with CMP and TX
EQ active ?

        Assume I leave the Mic Gain, CMP and TX EQ at the same setting when
the DVR  CQ message was stored …  When playing the message back on
the air, would the message be processed twice (CMP & TX EQ), once
during recording and once during playback or just once ?

        Feedback will be greatly appreciated.

That's exactly right. Most mics should have TXEQ set for maximum cut of
the three lower bands, with 6 dB cut of the fourth band, everything else
set "flat" -- that is, no boost or cut. A few mics benefit from a few dB
of boost in the higher two bands.

Once TXEQ is set, then set MicGain per the manual, then adjust CMP so
that you see no more than 10 dB of compression on peaks of TX audio.

This will optimize audio for best communications quality, and for
performance under weak signal conditions, boosting your "talk power" by
nearly 13 dB. The recommended low-cut is typically good for 2-3 dB --
that's how much power is wasted by low frequency components of voice,
which make no contribution to intelligibility.

Hi,
Does the satin black powder-coating match Elecraft?

I'm working on a addition to my KX-3 station, and now have access to
powder-coating equipment, but don't have access to samples of various
samples right now.

Some of you have figured this out, I'm sure.

73, doug

BTW, I've been out-of-touch, and have 25000+ email messages in the
Elecraft and KX3 mail directories.  And that's after catching up a bit.

I don't have any Elecraft to compare it to yet...

But the flat black I got from Witt's Powder Coating in Bossier City, LA
is an almost EXACT match with Heil boom powder coating...

Well...  since O was only doing a mic body and a suspension mount (total
of 4 small pieces), I piggy backed on their regular flat black run and
it only cost me $40 cash...

As long as I can get great service and that pricing, I won't be doing
any on my own.  :)

Night y'all... I gotta study and sleep.

73,
