Taking a MPA out of band

How far will a VHF MP-A go out of band? I have a B5 (146-162) split MPA and want to know if it will transmit on 143.9 without problems.

I'm sure it would work... I forget now - your TX is 143.9 or the RX???
May need an alignment tweak if that would be the RX (TX would probably be just fine).

I've found M-PAs are really a shot-in-the-dark as far as how far out of band they will go. (At least, without some re-tuning). Some stop dead at the limits of their bandsplit, and some will go sickly, obscenely OOB. You just have to try with your particular radio. And if it won't lock, then you just open it up and re-tune a little. Search around on the web - a lot of places have lots of the old manuals around, and you can DL them to have the tuning procedure at hand.

I'm trying to get my 450-470 MPA to program to 440.00 but my mpa sw (ver 11.1) gives me an out of frequency error and I'm locked out of the program. Is there a special key stroke I type while typing in the frequencies like some motorola RSS does.

Thanks

I think it's Ctrl-e or Shift-e when you want to enter out of band, as opposed to the regular enter keystroke?
