KX3-MH3 Mic gain settings ALC level ?

Hello,

just received my KX3. I tried to setup SSB according to the manual.

I am not able to reach the rcommended 5 bars an the ALC meter with
normal speech, only if i whistle some bars on the ALC meter are
visible.

I can hear my voice in the headphones. If i change mic gain the voice
changes too.

Any ideas are welcome.

Thanks in advance

Mathias,

Do you have bias turned on? Menu MIC BIAS parameter = ON. That is
needed for the MH3 microphone.

Hello Don,

BIAS is set to ON. The microfon is working, because i can monitor my voice an hear changes in loudness if i change Mic gain. I only can get the 5 bars when whistling in the mic.

That means it is time for an email to [hidden email] - there are
no easy answers to your problem and it may involve additional
measurements. While I could offer some guesses, working with support
will give you a better path.

Same problem here with s/n 1181.
MH3 output far too low.

Re: KX3-MH3 Mic gain settings ALC level ?

I have no problem - my mic gain is set to 40. That drives the ALC up to
5 bars with normal speech.

Similar here. With MIC=31, CMP=16, MICBIAS=ON, my MH3 drives the KX3 to its
target power level with four bars of ALC, occasional fifth bar, occasional
bar or two on the CMP scale. I also have VOX GN=10 for VOX operation with
headphones. That setting should be irrelevant for PTT operation. Either
way, the monitor audio sounds great and I get good audio reports.

Mike
I also had this exact same problem. Only when I set the mic. gain to 40 did I get 4 to 5 bars and only when I was speaking very loud or whistling.
I took my mic. apart and the element inside was partially blocked by the mounting rubber.
I pushed it in all the way and this helped a bit.
The biggest thing I did was to adjust the 8 band equalizer to give some gain in the middle frequencies.
Now I have my mic gain set at about 30 and I get the 4 to 5 bars.
Worked for me and my voice, your mileage may vary.
