Fire Tone Outs

I have been playing with my 436 on the tone out search. Walkerton fire has had 3 pages and the tones were all Freq 153.8600 A 456.8 B 433.1.. Hanover has been paged out 3 times with 3 different tone outs

Freq 153.2150 #1 A 287.9 B 1089.3 #2 A 288.4 B 1091.2 #3 A 288.3 B 1092.1



My question is why do they have 3 tone outs, or because they are close its the same one and the scanner is misreading them

Thanks

Frank
