no reception on Pro-57.

just got a pro-57 that when programmed, there is no response in any channel. but when i program the same way with a uniden bc147xlt there are lots of receptions. both scanner are using the same antenna and both program with local public safty channel. Is it because pro-57 only work in FM mode? second question is does a uniden bc147xlt work in both AM & FM mode? (just want to make sure.)

Try adjusting the squelch. As for the uniden, read your manual or google it. I don't have any unidens but if it has the Air band then yes it has the AM mode.
BTW, if your using a Pro-57 then I'm sure your public safety channel is most likely VHF, around 150MHz FM, not AM.
