It has been some time since I posted last, but I wanted to share with you guys something I found on my MV pager and wanted to see what thoughts any of you have.
I posted before that my pager would not receive in monitor at all ( Somewhat common problem with the MV ) and it would still go off if a call was received, but the audio was very low. Today I changed the settings from WB to NB and guess what....... The pager starting working again. I changed it back to WB and it went back to being a POS again. I have no clue on why it is doing this, but for now I am going to leave it in NB and see what happens. I will keep you guys updated.
After doing some searching I could still not find a no BS answer for this question...... On the Squelch setting bar ( 1-5 ) what setting is for what ? All I can find is everyone going back and forth on 1 being lose and tight... I do know 3 is default and what would be the best setting for running NB in a area weak signal ?
Thanks for the help

Re: MV Squelch and NB
Been using the pager for 48 hrs now and I am happy to say that it is acting normal. I still have no clue as to why the thing wont pick up anything in WB settings even on a WB system and only works in NB. I hope someone who knows more will chime in on this. I can only guess there is some problem with the board and switching to NB somehow fixed the problem.
Re: MV Squelch and NB
I just started researching this problem as I have a low band pager that has acted up.
I will take a stab at the reason narrowband works and wideband does not: In many WB/NB radios, the intermediate frequency (IF) filters are switched, as you need different filters for NB and WB modes.
So when you go go from WB to NB you select a different IF signal path.
The low IF (455 KHz I think) filter is a ceramic type for both modes, and it may be that the WB filters are going belly up.
In the past I have seen similar filters go bad due to high humidity, vibration, etc.
I will have to make a comparison between a good low band M5 and a bad one and see what I can see.
