Personally these moles I find scary. Living among us for years but something sets them off one day. The dead brother was a two year medical student. Why give that up to bomb Americans?
Thomas Sowell: There are no solutions, just trade-offs.
A rather over simplified explanation, but hopefully it will provide the information you are looking for:
There are multiple ways that dispatch can patch frequencies/talk groups from different agencies together. However, doing so in a large incident such as this also runs the risk of having too many people trying to use the same frequency/talk group at the same time, resulting in chaos.
A better approach, and what is usually used in large incidents, is to utlize one frequency/talk group as a command frequency, available to the commanders only of each agency/task group, and used to coordinate among the agencies/task groups. Other frequencies/talk groups may then be patched together for specific purposes to allow multiple agencies that are working on the same task to talk together, while keeping the communications related to other tasks isolated to their own frequencies/talk groups.
These patches can be made whether the individual agencies normally use digital trunked systems or straight VHF/UHF.
Adding encryption into the mix significantly increases the complexity, and with that the possibility of failed communications. Encryption may well be used for task groups which involve agencies that regularly work together and have planned and trained for this purpose, but it is difficult to add another agency that is not normally part of the group on the fly during an incident.
Hope that is helpful.

This feed has been steady... but I don't think this guys scanner has as many frequencies programed into his radio as the first feed I linked to... I'm not hearing as much tactical info coming over this feed. It's better than nothing.
It could be that they have settled in on certain tactical strategies. I can't get in at all so keep us posted.
Even in a major fire situation here, once they have developed a certain plan of attack.....the scanners go pretty quiet. Often they will move secondary traffic to another frequency that is unavailable to the public.
