Sorry it's taken me so long to reply to this, work and all that jazz.
That being said, I've never read more *fail* from someone who claims to be "in the radio field".
Encryption does not "overload a digital radio system". The system does not care about an additional or changed bit in the data stream. If it did then no current systems would handle encryption and they would indeed be untenable.
You then go on to relate several anecdotes with the sources cited as the equivalent of "trust me bro", with the examples sounding more like poor programming, operator error or just plain falsehoods.
You finished by stating the FCC has shut scanner feeds down for rebroadcasting "tac channels", causing the feed providers to lose their privileges.
Really? Cite a single 47 CFR FCC regulation that covers this, and further enables them to do what you stated. I'll wait. In the meantime, feel free to search around for feeds providing tac channel traffic. I'm listening to one at this moment.
If you are truly "in the radio field", I cannot imagine the unadulterated BS you must spew at customers. With this attitude you should not be allowed near a toaster, let alone any actual technology. I believe your entire topic would meet some sort of guidelines for misinformation if one does indeed exist.
