OK, still very hard to understand. Channels 1-4 are main dispatch, fireground, secondary fireground and tertiary fireground/fire alarm construction. All of these channels are currently analog and IN THE CLEAR (read NOT encrypted.) This is where almost all two-way traffic currently takes place. Channel 5 is two-tone paging and is used for station alerting-there is NO two-way communication on this channel, only one-way paging/voice announcement FOR ALL DISTRICTS and STATIONS using voice allocution-this channel is also analog and IN THE CLEAR.Sorry I had spell thing on on the digital side it side dist 1 _10 alert channels are wncrpyred but someone got ut stright he side they use uhf but if crosses over 1-4 is clear but all other alerting chsnnel.on digia site is exrpyted.makes no sense do they use all alerts channels are just ones us what im asking
As said above, if you have channels 1-5, you pretty much hear everything. I don't know if the district repeaters (they are not district "alerting" channels) are up and running, but as of right now there isn't much, if any, traffic on those frequencies. Just because a frequency is licensed and listed for use, remember that could be a FUTURE use.
Wherever you got your information is wrong. The people who have tried to answer your question/assertions are all local to Boston, some posts in this thread were even made by the guy in charge of the BFD's radio system, yet you still attempt to claim that your information is more reliable than those of us that are listening to the system (and have been for decades) as we are answering you.
