Steve,
Since this K3 is 'new to you', you can't know how the prior owner has
set things.
Check the settings in the TX EQ first. I would suggest that you
initially set all bands to flat. For communications quality, normally
you want to reduce the first 2 bands to the lowest settings and the 3rd
band by 3 to 6 dB. The lower frequencies take a lot of power but do not
improve communications and intelligence. OTOH if your listeners are of
the ESSB kind, they like a lot of bass in the response.
I have known one instance where that symptom was cured by calibrating
the Reference Oscillator. Follow the instructions for Method 2 (Zero
Beating) in the manual.
Do not overlook the fact that you may have a bad microphone. Take an
inexpensive computer microphone and plug it into the rear mic jack, set
the MIC SEL to the rear jack and turn bias on. Those computer mics
normally produce good quality audio.

Hi all,
I have a newly acquired slightly used K3. Feedback on my voice audio quality
is that it sounds tinny with no low or mid range. Unfortunately, the K3 manual
really doesn't provide much guidance on how to adjust the transmit EQ other
than the mechanics of what buttons to push. If I need to increase the low and
mid, does this mean I should increase the values of the first half of the 8
settings and decrease the second half..or something similar? It's been a while
since I've dealt with audio equalizers. I would appreciate any suggestions.
