re: “ he said was that the police and SS were on different radio channels so the communications were all screwed up.”
[Expression of disgust here b/c poster is painting with a broad brush]
NORMALLY a command and control center handles this by coordinating the different LE agencies involved, Local PD, Sheriff and USSS, each with their own digital P25 radio systems and EACH with their own encryption ‘key’ loaded into each radio via a key loader. Rather than mass reprogramming of radios (with new trunk talk groups) the Command a Control center, again, coordinates activities between radio systems and any coordination between groups. THIS is also an advantage BECAUSE so much traffic is routine anyway - so ONE channel is not tied up with each agency doing routine ‘ops’ (like reporting on station, etc) for that special activity that day.
In the past (don’t know about now) USSS has been on VHF High-band and local LE has migrated to trunked 800 or 700 MHz municipal systems that have other users like Streets and Water and even garbage collection user groups.
There are special radio interface ‘boxes’ (several RX/TX capable radios tied cross-channel) offered by Harris and Motorola than ca virtually ‘tie’ two or more disparate radio systems together, it would be fair to assume they would use one or two of those for at least ONE common channel between USSS, Local PD and the Sheriff for use as needed.
The question is whether people were getting the communications they were supposed to be able to get. And it’s a question because the SS agents with Trump should have known there was an active shooter situation but they acted like they didn’t know that.
So are you saying that the communications were fine, or just that you think the former SEAL who was talking about this was assuming that there were communications issues just because there were different channels being used (which you seem to be saying is normal)?
What I want to know is why the agents with Trump didn’t get him out of line of sight when the SS was clearly dealing with an active shooter situation. Do you have any insights about that?
