Your description made it sound like ATC would not retransmit unless they
were notified that their message did not get through to you. That certainly
is not the case. They will wait 10 or 15 seconds and retransmit, if you
don't reply.

It is more efficient for everyone if you just wait for ATC to re-transmit
the message to you without broadcasting a "blocked."

Even if you hear your tail number but the rest of the message is garbled, it
is better to wait. Any attempt to alert ATC that they were blocked risks
further delaying the original message and causing confusion.

For all you know, it was blocked by some guy broadcasting "Mayday, Mayday,
Mayday." Stay off the air and let the protocol do it's job. The protocol is
designed so that the originator of the message has responsibility to make
sure the message got through and was understood. Your job as a receiver, is
to wait and listen.

Another observation is trying to identify who said it, not
publicly on freq to humiliate, just to myself. And so far
it's been someone who isn't even on freq yet, someone
waiting to check on, yet feels they should throw in their
"blocked", big help.

About the only time I do it is if transmissions ARE blocked, all I hear is
a squeal, and I'm expecting a call from ATC. That call might have been my
clearance for lower, which I've been expecting and really want, but I
couldn't tell. I want to find out, but I don't want to make a long call,
or antagonize the controller, so I might just transmit a 'blocked' so I
can
get a retransmission. It's rare, but it sometimes happens. Otherwise I
just ignore the squeals, because I usually have more important things to
do, like keep the aircraft right-side up, on course and on altitude, or
else make sure the FO is doing all that. If I transmit a 'blocked' it's
because I really wanted to know what was said, and I couldn't understand
it.
