Pokey - I think I may have just heard the previously unseen tone combination you originally wrote about. At the regular 8:10AM checks this morning I heard (and recorded/decoded) a two-tone test followed with "XJF 647 Milton Fire Department Pumper 41 pager test, 1 2 3 4 5, 5 4 3 2 1, 8:14", then the same sequence repeated a second time, EXCEPT:
The first tone combination was 727/1251Hz. According to what I'm looking at online, that would be 1 tone from the Reed Group one and 1 tone from Reed Group two. I've never seen a cross-group two-tone page from MFD or HHFD before. The second P41 test followed the first using the regular P41 tones. Both tone-outs were preceded by the "Pumper 41 pager test......" announcement with virtually no delay between the two.
The P31 tests which were done prior to this stuff were totally routine.
Did he hit the wrong tone-out button, or is this something new? Only time will tell. I've recorded the morning tests for the last 10 days now and this is a first for me, so it's not like it's happening daily. P41 was at station 4 as they did respond to the "Station 4 base paging, how do you receive?" request.
