New build K3S no speaker audio, low mic gain

[Chuck Chandler]

Well, the K3S is running, with KPA100 installed.  I have done all the
calibrations suggested.

Two items for now:

No speaker audio, though headphone jacks front and rear work fine.  I tried
the CONFIG:Spkr+PH to minus thing, no change.

Also, trying my Heil Quiet Phone had very low gain - there must be a mike
setting, but I can't think of it.

Tomorrow is sub-receiver installation...

Chuck,

Contrary to what Heil recommends, set the mic gain range to high for
those low output Heil microphones.

For the speaker audio, I suggest you contact K3support and they may be
able to guide you though some tests.

On the speaker topic, please check your Owner's Manual Errata - 2nd item.

Agreed with Don on the mic input.  Also, please be sure to read the section in the Owner's Manual about how to set proper mic audio drive levels - it is different from other radios.

Cheers,

David/KG6IRW

Which speaker doesn't work, the internal speaker or an external one plugged
into the SPKRS jack on the back?

If internal, did you remember to connect the 2-pin cable to the header
before putting the top cover on?

If external, did you use a stereo plug or a mono plug?  If mono, did you
set CONFIG:SPKRS to 1?

Re. mic gain, there's a SPEED / MIC knob on the front of the radio.  Did
you turn it?

What type of Heil mic do you have, dynamic or electret?  From the K3 manual:

MIC

MONO; hi- or low-Z

"This jack accommodates an electret or dynamic
mic. Use MAIN:MIC SEL to select the rear panel
mic (RP). Tap 1 to turn on Low or High mic gain
range. Tap 2 to turn bias on/off (see pg. 28 for
recommendations based on mic type).

"For the front-panel mic only, additional microphone
gain can be enabled by tapping 3 . Use this only for
very low-output mics."

Chuck,

Looks like your reply didn't go to the list, so I'm quoting it below for
the benefit of other readers.

It looks like KG6IRW has the solution.  From the Owner's Manual Errata:

"IF THE SPEAKER IS NOT WORKING with headphones unplugged: Locate the
CONFIG:SPKR+PH menu entry. Tap ‘1’ on the numeric keypad until you see PH.R
SW–. The minus sign (-) indicates inverted switch logic for the jack on the
KIO3B audio board. Exit the menu and re-save your configuration using K3
Utility."
