Default Wiring diagram for GA radio/mic?

Would anyone be kind enough to point me to a wiring
diagram for a general aviation radio?

I need to know the pinout configurations and voltage
for the mic connection.

Thank you and regards in advace!

Gary --

No offense, but you are getting to be a PITA with this microphone stuff.
Ask the question in ONE newsgroup and you will probably get the answer you
want. Ask it in three or four and you are being a nuisance.

Have you answered him, Jim? You should be the one since you're the go
to guy on radio work.

Gary, has Jim answered your question? If not keep asking. If so, his
answer is correct, look no further.

Definitively, in RAH, where he started this post in the first place without
spamming it across four newsgroups.

With all due respect - why is it that you care about that.
If it doesn't concern you, why bother?
I don't see that many people agree with you on that.

Judge and Jury convened and departed in your mind already?

No - I did not get an answer.

Most thankful regards,

Gary

"With all due respect" - perhaps after posting in multiple groups,
you neglected to go back and check them all for "an answer".

It sure looks like you got an answer to me, just not in RAM.

If you think you'll get anywhere twisting Jim's tail, knock yourself
out. The really, really funny thing is, he's probably the best 'group
resource available for concise, accurate answers to GA
avionics-related questions.

see below;

From RAH, not RAM

Same thread, also from RAH

There is VERY low voltage involved -- #22 AWG (shielded) wire will
suffice.

There are three hookups to the jack: Mike Key, Mike Audio and Mike Ring.

Ring goes to Ground

Key goes to a switch, which grounds the key circuit. This activates the
transmit relay in the radio.

Mike Audio passes straight through to the radio audio circuit and
carries the voice. This wire should be shielded, to reduce EM
interference.

IIRC, the audio is the tip of the jack; the key is the next position on
the jack. Ground is the outer (long) part of the jack. Check with a
circuit tester.


Still in the same thread...

Not quite, Orval. From the leading edge of the male connector (microphone
end as opposed to the aircraft end) the sections of the plug are tip, ring,
and shell.

Grounding the tip places the transceiver in the transmit mode; ungrounding
it (open) leaves the transceiver in the receive mode.

The ring carries the microphone audio (more later).

The shell is airframe or chassis ground.


The mic audio line coming from the transceiver is a current source that is
intended to provide a 300 ohm mic element with about 10 mA. Generally this
is a simple resistor fed from a quiet regulated supply inside the
transceiver. I usually use the +10 volt supply and a 680 ohm resistor. The
microphone circuit is designed to emulate a carbon microphone (variable
resistance with audio) and will give somewhere between half a volt and a
volt peak to peak with normal mic audio.

Yea, and when Arnold beat him in the California gubernatorial race, it
really sent him over the edge ;-)

Yeah, and when Arnold gets his ass handed to him on a plate in next week's
elections, I'll chuckle that it was my colleagues (teachers, cops, firemen,
public service nurses) that did it.

He who laughs last, laughs loudest.
