As is often the case for conventional fire systems, TAFL is our friend
(to mis-quote am over-used catch-phrase usually applied to Google).
Search on "Lanark Highlands". There are two frequency pairs
153.815/158.550 and 153.815/158.925, plus simplex on 150.530
(new tactical?) and 154.070 (OFM).
There is no indication of narrowbanding, even analog, so who knows
how long the analog status will hold. Let's just hope they don't go TRBO
(did I day that!?).
Speaking of fire frequencies, I recently started picking up South Stormont
FD repeater out on 154.635, good signal into Ottawa. That was the old
Nepean Works channel, which was left in a scanner.
