[Elecraft] CM500 mic keeps cutting out midsentence

[Ron D'Eau Claire]

Zero VOX Gain should mean that *any* sound picked up by the mic should
initiate transmit.

The Mic delay means that when VOX does drop out, there's a 0.9 second delay
before it reasserts after the mic picks up sounds. You might try reducing
that to see if there's any effect. 

Presumably you are seeing 5 to 7 bars of ALC on the bargraph indicating
normal mic audio levels into the K3. 

Try connecting the mic direct without the Microham to eliminate the Microham
interface.

Try transmitting PTT to determine whether it's the VOX setup or an
intermittent in the mic wiring.

I'm having problems preventing my Yamaha CM500 boom mic from cutting out
intermittently while talking.  I have the following settings on my K3:

VOX Gain: 85
Anti-vox: 0
Mic delay: 0.90
Mic Gain: 30
Cmp: 25

The mic is routed to the K3 via a microHam MKII.

I have tried moving the mic to various positions but this doesn't help.  TX
cuts out every few words and this is very annoying! I have to raise my voice
above normal conversation levels to get it to turn the transmitter on.  I've
play around with various values, but I'm not finding a good combination.  Is
there another setting I have forgot to address? Maybe I've got a loose
connection in the mic itself? Not sure how to take this apart for
inspection.

Thanks for any any and all suggestions!
