Sqelch Settings No Effect and audio listening fatigue and noisy computers.

[KD8NNU]

I have enabled the ability to change the sqelch settings to try and
reduce some of the background static.  However, no matter how I adjust
it from 0 to 29 it has no effect on the audio.

Is this normal or do I not understand the function in the K3.  In any
other radio I have owned in the past this would lower the static
threshold.

To try and improve the audio I have gone to an external equalizer and I
hope this will help with the hearing fatigue I get with this radio.  I
am wondering if part of the problem is the Heil pro 2 that I purchased
with the radio.

I am slowly playing with filter settings, NR, NB ans so on and I can
definatly pull out signals.  I have been listening all over the bands
with the contest going on so I can tell the differences.

As a final statement I also had to ditch the tower computer and go to a
laptop as the computer was putting lots of noise in the system when I
connected it to the K3 even with a good shielded USB to RS232 converter
with 6 turns in a 31 mix bead.  I changed to the laptop and this noise
is not there.

Anyway I am making progress but I would like some ideas on the sqelch.

One final question is there a good users guide that helps to explain all
the different settings and how making changes affect either RX or TX and
what are the interactions between these settings.

Thanks in advance for all your help.

Hi Don,

On pg. 59 of the manual, it states:

"*This menu entry normally sets the main receiver squelch value (**0**-**29*
*). If VFO A is rotated fully clockwise, the parameter changes to **=SUB POT
**. Squelch for both main and sub receivers will then be controlled by the
SUB RF/SQL knob, and both main and sub RF gain will be controlled by the
MAIN RF/SQL knob.*
*
*

*Note: By default, squelch applies only to FM mode. Tapping [1]** **while in
this menu entry alternates between **SQL=ALL **(all-mode squelch) and **
SQL=FM**.*"


If you want to use squelch in all modes, you'll have to tap button [1] while
in the SQ MAIN config section.

Try keeping the User's Manual PDF on your desk top. No kidding, it's a very
helpful way to learn the ins and outs of the K3.73,
