Apparently I'm not the only who thinks the backup site sounds bad. There have been many requests from dispatch to officers to repeat what their transmissions, one dispatcher said "I'm sorry, these backup site radios are.... bad."
This always happens when they switch to the backup site. I hope that they get the bugs worked out and things working better, as it should be as seamless as possible. Dispatch doesn't seem to have full access to LFR's tactical channels at the backup site, I don't know about the police side though and what access police dispatchers have.
