As it would have Bill...if indeed a PCMm RX was employed, as the communications 
protocol would have been different (except in the unlikely case the offending 
TX was identical and on the same frequency). A PCM RX would immediately have 
gone into hold, and then would have either returned to normal communications if 
the proper signal returned or entered falisafe after a set period of time. In 
some cases depending on manufacturer this delay can be altered.

Sorry to Randy for calling him Pat <grin> Randy claims to be be the tall good 
looking one (trust me...I have no desire to find out but maybe Gordy could 
comment for the edification of all :^) 

Some may recall me posting on testing I did on versions of a neat RX (Sky & 
Technology) which employ rather complex algorythms which dissect a specific 
transmitter's signal O/P looking at (and remembering) anomalies which make that 
TX unique.

The result is you can turn on another TX (identical make/model in some 
circumstances), and it will not interfere. Pretty extraordinary! In fact their 
particular system touted that you could have two TX's on precisely the same 
frequency, program the RX to uniquely identify both of them, and then 
use "both" TX's simultaneously in a student/instructor environment. 

The neat idea being that the RX would know which TX is master and which was 
slave. When the student got into trouble with his slave TX, the instructor 
would turn on his master TX, all on the same frequency, and take over. There 
were a few fly's in the ointment though;  

- the TX's had to pretty simple units, such that when they turned on they 
outputed a valid signal immediately. Not something you can do with today's 
microprocessor-driven TX's (start-up delays, etc).
- there were times when on two identical TX's were employed, the slave OR 
master could still overrule the other.

I still operate a few of these RX's, as they are IMO as good if not better than 
PCM for precisely the reasons poor Randy got bad juju.
