When entering a class-B, I call up approach at the appropriate time. I
will not be talking to ATC prior to that transmission.

An appropriate time is outside of class B, when approaching to enter. This
is the time we are discussing.

Better ratchet up that "wrong" counter one more.

George's comment was clearly with respect to the state in which the pilot is
*before* attempting to contact ATC. I think it's entirely plausible that
most VFR traffic would not already be in contact with ATC, prior to the
point in time at which they decide they need to contact ATC for the purpose
of entering the Class B airspace.

IFR traffic will be (but doesn't care about the boundaries of Class B
airspace anyway), and VFR traffic already in contact with ATC (because they
are using VFR radar advisories, for example) will, by definition, already be
in contact with ATC. But plenty of VFR traffic won't be, not until that
first call to ATC to ask to enter the Class B.

Thanks. Somehow I just wasn't getting that across.

If a tank is out of ammunition, what you have is a sixty ton portable
radio.

You'll never have to worry about ME doing that, Jay!

Henry, I thought you had a radio with some whizz bang options to allow you
to tell when the frequency was busy so you wouldn't step on others
transmissions.

You are correct, but I didn't read it that way. I read it as most VFR
traffic would not be in contact with ATC =as= they enter class B, or
within it.

Actually I thought I was wrong, but it turned out I was mistaken about
that.

Most programmable communications transceivers have a timeout feature
(with selectable delay). Really helps in stuck mike situations (and
pulls the rug out from under long-winded people, too). All 2-way
transmitters should be so equipped.

The guys who designed the original EtherNet anticipated this problem and
built an "anti-jabber" circuit to every node.

And if the stack has an audio panel worthy of the name, the opposite
transceiver's audio is cut off during transmit to prevent an unholy squeal
coming down the audio line of the receiver that is still operating.

hmmm... what I had in mind was a split (pilot/copilot) stack, but upon
further thought the transmitter would overwhelm the receiver, even though
the receiver is not switched off.
ss.

You sure? I've operated split (on different frequencies), and not been
cut off when the other pilot was transmitting. Does the audio panel
know what frequencies each radio is using?

It has nothing to do with the audio panel. There is a "transmit
interconnect" wire between radios. It doesn't always get installed. I had to
have one retrofitted after completion of my Garmin 430---King KX-165A
installation.

With such an installation, wouldn't each pilot be frustrated while the
other pilot is transmitting, defeating much of the purpose of the split?
