CB mic wiring
 

I am trying to adapt a CB "roger beep" mic for ham radio and there is
some odd terminology for CB mic wiring.

The CB'ers call "PTT" "transmit (TX)"

They call "audio-out" "audio" (not too bad)

They have a separate line for "receive (RX)" which some call "receive
control." What is that for? Anyone know? By testing, I know it is
not for a speaker in the mic. It shows 6 ohms to ground.

Tie 1/2 of the wires together, then tie the other half together, then plug
into a wall socket.
That will take care of the problem.

BTW... there was a ham in these parts that put that crap on his mobile ham
rig.....one morning he came out to find that his mic and rig had come into
contact with a large, high velocity, inertial impact device.

Hi Ken -- ignore the nasty replies

About Roger Beeps on Ham Radio
Tis highly frowned on
If you use it on a repeater -- sixteen+ Hams will come back and say you have
a roger beep tone
You say yeah I know
They say -- get rid of it - it sounds like CB
No FCC rules against it - but it's considered poor practice
Repeaters have a courtesy tone (beep) so your beep is not necessary

On HF - also frowned on -- if noisy conditions - just say OVER

CL -- I doubt, therefore I might be !

I always ignore the crackpots; most have no lives and nothing to say
of value.

Well, NASA uses roger beep with its astronauts and ham repeaters use
them all the time, but call them courtesy tones. So I see no problem
with experimenting on SSB, especially with folks I know who have no
objection. Especially if the tone if not loud or extravagant.

Ok... you got 3 replies that all said *don't do it*, and you want to call
all 3 "crackpots" and ignore what they have said. Consider the levels of
experience you are dealing with. Personally I have been licensed since 1984.

If you absolutely must use a beeper, then do it on the Childrens Band.. not
on the HAM bands.

In spite of my agreement with most of the flames thrown at you about this,
there are certain applications where "curtesy tone" is warranted - as few as
they may be.

So that out of the way, often the RX is used to enable/mute the audio If the
RX is pulled low, it enables the audio path to the audio output. If open it
will mute.

Hello,

In a decent way, these tones could probably be useful during contests or
when propagation conditions are weak (V/U/SHF). But beware, don't abuse it,
or you'll be called a Johnny.

Repeater beeps (was CB mic wiring?
 

On repeaters the beep is more than a courtesy tone
It also signals that the repeater timer has been reset.

Transmission times are accumulative, if folks don't wait for the beep.
Example: A machine has a 60 second timer and station X talks for 50 seconds,
if station Y comes in before the beep, 10 seconds later the timer will shut
down the repeater. To signal a timer dropout, some repeaters use a voice
announcement, others use a series of short beeps, such as a triple beep.
Others may use a short delay, a short beep and then dropout.

As i said before -- if you use a roger beep on a repeater, a dozen plus guys
will alert you that you have a beep tone and ask you to turn it off

I see no reason to use it in any mode with a carrier; you know when
the other guy has released PTT. As I said, I want to try it on SSB
where you need an "over" to know PTT has been released. Some hams
think you are a lid unless you say "over"; I see no reason to make
like a simple machine, unless you have the IQ of a simple machine.

I believe the FRS radios also use a roger beep. They probably outsell
ham radios 100:1.

Except for repeaters, they have no good use, but if you must, I agree with the
above.

A distinction here is that the repeater itself puts the tone on to
signify when the timer has started. The tone is not superimposed by
the person using the repeater.

There are only a couple of times when transmitted audible tones are
used. One is for a repeater autopatch. The other is to awaken Litz
decoders for emergency traffic. Beyond those two applications,
audible tones have no place in amateur radio. They need to stay in CB
land.

Have you considered suicide? You should.

Suicide would be good for anyone calling himself diamond dave.

Actually NASA used "quindar tones" which are in-band signalling to
activate ground transmitters. Those beeps were removed by a notch
filter and never made it into the uplink.

The question to seek is WHY are they there?

The "courtesy tones" serve a purpose (yes that is a funny name and I don't
know where it started, but)...to tell when the timer is reset.
