[Repeater-Builder] MSF5000 EPROM Controller

2010-03-07 Thread KE4ZDG 
Hey folks,

Any idea what would make an MSF5000 CLB EPROM controller randomly reset (test 
lights coming on)?  When it's not in self-check mode, it works fine, but 
roughly every 3 mins, it resets itself.

Thanks,

Jared

One thing that comes to mind is the power supply caps.

Go to this page http://www.repeater-builder.com/motorola/msf/msf-tour.html

Scroll down to the paragraph on the Analog Control Tray.

Change C702, C706 and C851.  C706 is especially troublesome.
In fact, these should be looked at, and probably changed before
the station goes into amateur service.
