[Repeater-Builder] MSF5000 Tone Issue, PL 131.8 opens cor, non 131.8 keys repeater but no audio

[n9lv]

I have the analog MSF5000 repeater that has the Cat300DX repeater 
controller installed.  Not sure if this has been this way all along, 
but I noticed there is another repeater somewhere close that has a 
different PL.  When they are using there repeater, it will cerchunk my 
442.000 repeater.  My PL is 131.8, and that will open the squelch and 
allow audio out the repeater.  Any other PL will not open the repeater, 
but will consistanly cerchunk the repeater and causes the courtesy tone 
to trip as well as the rest and wait id timers.  Any ideas.
