Sorry to digress but as "to many frequencies" is/was mentioned:
I was riding "shotgun" on a trip and we stopped in Moree. We stopped off to get fuel.
There had been a problem happen with heavy rain the night before and the plane wasn't in a good way.
Did the fuel check and started the engine.
The active runway at the time was the north one. There was a LOT of traffic as it was the end of a fly-in happening near bye also.
"Bah, I'll take off southbound." was the PIC's attitude.
As we took off we nearly hit a plane landing on the northbound runway.
The idiot pilot on the plane didn't bother CHECKING the frequency of the radio.
Yeah, ok, when we came/went into Moree it was on the right frequency and all we did was shut down and power up.
But given the plane had electrical problems: that is something that should have been DOUBLE checked.
The fact that the frequency was QUIET AS...... Should have been enough of a warning that it wasn't on the right frequency.
With all the planes you would expect to hear SOMETHING. But it was quite and the PIC just decided to ...... "Ah, I've broadcasted. That's my part done." Is a rather pathetic mind set.
So I think that as much as it is annoying having too many people talking on the frequency - another story - people should learn to WAIT THEIR TURN.
And given this was "the normal" for the pilots...... It doesn't hold much credibility for me.
(Just saying)
