Obviously (or so I thought) anyone with a basic knowledge of how a 2-way
radio works knows that the receiver is necessarily cut off during
transmissions -- but apparently there are a fair number of people who don't
have a firm grasp on this concept.
Jay,
At one time, one of the ground wires in a PTT switch broke and
appeared to allow both transmission and reception at the same time.
Rick was at the left seat. In realizing that his PTT switch was not
working he asked me to communicate with ATC. While taxiing, we kept
testing the intercom system and headsets : "Testing 1,2,3. Do you hear
me OK? Does this headset work better. Hmm, what's going on here?
Should we go on or should we abort this flight? etc". Typically, I
kept my hands/feet clear of the controls when not being the PIC, but
since I had to operate the PTT switch, my hands were resting on the
yoke. At one point, Rick yelled at me: "Keep your hands off the yoke,
you made me nervous!". Few minutes later, the tower called us:
"N30703, are you having some radio problems? We could hear all kinds
of conversation in your cockpit"!!!!!
