So far it looks like Fire is not encrypted in SIRN, but their previous frequency is patched which is encrypted. TAC channels are not, but that could change.
I was listening to them a week ago on my BCD996P2 and they disappeared same thing with PD, FD. I had 2 brain surgeries, which resulted in seizures so I can’t drive and stuck at home so I need/want the radio to keep me company.
