The obvious solution to this problem is to make it impossible to get a hit. That can be easily done if Tx and Rx are able to expand on PCM technology by sending "headers" with each transmission that uniquely identifies the code sent as belonging to your TX and not someone else's. If your Rx can disregard bogus input then the problem is solved.
Any thoughts on this guys?
Yea, spread spectrum would be much easier to implement, would virtually eliminate "hits", would still allow you to operate with the current "fixed" channel sets without them interferring with you, or you with them and would not increase "bandwidth" usage on the link appreciably. Much better than trying to come up with some sort of "IP" solution that would be implemented in a proprietary manner by all the different manufacturers so we'd be back to only using X brand Rx's with X brand Tx's.
As to the ability to get into the code, bad idea and I'd protest vigoursly any move to do so. Of the 10 people I know well who use programmable radios, 6 have not bothered to read the manual past getting the ability to do basic stuff, 2 have read the manual, but don't understand it and 2 really know how to use the radio. That's 80% who are dangerous with the "programmability" of the radio. I REALLY don't want these guys having the ability to get into the code and really screw things up!
