I know that certain police and FD units definitely have used 147.505 MHz (springfield OEM ham repeater) whenever something major occurs. The last time I personally heard them was when we had that terrible flooding. There is one small bridge in Springfield that gets wiped away during any type of flood and they have sent boat crews out in the past, posted in that area who have used the OEM repeater. BTW, I didn't know they had a secondary repeater on 446.375. I'll make a note to check it out next time we get too much rain. Thanks for listing the additional frequency.
