Does anyone know if there is a way to adjust the squelch on a BPR40 without CPS? We have 4 of them, and get some interference from our cable system when we're in the shop (cable distribution is on the other side of the wall).
I have a couple of Sabers, and am able to squelch out the interference, but the BPR's are annoying..
Our repeater doesn't transmit PL, so we can't PL it out, and we don't want to spend $300 for software we would never use...

Re: BPR40 Squelch
If you remove the BPR40 battery, you will see 4 stickers covering holes in the chassis, 3 small stickers and one large one. If you remove the large sticker, you will see two pots, the left one(looking at the rear of the chassis) is the squelch pot(R215). You should at least have a service monitor to adjust R215. The programming software will not help do what you want to do because the radio has no softpots, only physical adjustments.
The correct way would be to reprogram your repeater to transmit CTCSS or digital PL because what you are trying to do will not be effective when the radio is moved from areas where interference is low to areas where it's at a high level.

Re: BPR40 Squelch
OK, we found the pot, but we can't find a screwdriver that's small enough to fit it (I'll have to bring one from my own precision collection, I guess)
The repeater is an ancient Standard RP70U. It's supposed to transmit PL, but it doesn't, and I can't figure out why... I imagine the tone board is screwed or a connection is broken, but I don't want to make things worse.
I'm trying to get the management to spend the money on a repeater built in this century, but they are >$500, and they don't want to spend the money, since there is only one place in the building that breaks the squelch...
My only hope of getting management to get a new repeater will be to remind them of narrowband requirements, which our repeater won't do...

Re: BPR40 Squelch
I neglected to mention it, but Motorola sells a special ceramic metric alignment screwdriver that's tiny for that adjustment. If you use one of your own, I'd suggest that it should be nonmetallic to avoid shorting anything.
Since your management should know that narrowband will be required as of the end of next year, can't you convince them to bite the bullet and do it right now?
