Export Radio w/ Power Microphone - Radio Key Up, Audio Delay Issue
This is something I thought I'd mention since it's come up a couple of times in emails I've received lately.
With some radios when adding a power microphone you might encounter the following issue.
"You key up the radio and everything works normally but when you begin talking sometimes there is a 1 second or so delay before your radio starts picking up the audio."
This can be annoying as the first word or letter of many sentences will get cut off.
I've run into this issues specifically on the 2950DX and the CRE 8900 when running astatic power microphones.
The fix is to place a resistor from the audio to the ground and it can be done inside the microphone or inside the radio. I ran into this problem a while back and eventually found a great thread online explaining that a 1k resistor from the ground to the audio would solve the problem and indeed it did.
I've included a picture of the road devil I wired for the cre 8900 and the resistor I installed in that microphone to solve the issue. I would recommend using some shrink tube on the resistor just in case to prevent issues since space is limited in many mics.
This solved the key up audio delay issue with the RD/CRE 8900 combo and I haven't had any issues since.
It's a rare problem to encounter but I figured at least I'd post up the info.
