Frequency congestion, wasn't that why you stated this thread in the first place ?
Yes, that's correct, and to be more specific, the reason for me to raise that issue
has been the fact that, as a result of combining several frequ., you get a lot of only
E.g. a pilot asks ATC for a deviation for weather, the controller does not respond
instantly, and the next you hear may be "cleared ILS 27R, maintain 180 KTS to Jalto".
Or, if you are patient enough listening to JFK GND, you are rewarded by catching
the second half of a clearance, or, even worse, you hear a pilot calling CLNC DEL
ready to copy, and the next you hear is "left on B, short of N....."
No matter for what reason one listens, that does not make much sense to me;
it's not fun, and I wonder what's the use of listening to transmissions that are
interrupted by an ongoing transmission on another frequ., as soon as there is a
tiny lag btw. an instruction or answer and the response.
My suggestion would be to to feed some of the scanners only with one busy
frequ., like René ("dutchmil") did last sunday at EHAM - see a previous post -
that was really fun to listen to, and very useful, too.
When feeding more frequ., may be it would be more practical increasing the time
a channel can be silent until the scanner starts scanning... it's just an idea that
comes to mind while I am writing, but I do not know if there is an option to adjust
the scan delay time.
But, in case it is, that would probably reduce interruptions and provide more
consistent communications, at the cost of a couple of seconds of silence in btw.
The example of LAS shows indeed that there will be no single solution to satisfy
all needs; I agree with tyketto that past midnight listening to only one single feed
would be not very interesting.
