Hi All On Superstition mountain in the Imperial Valley we have a S-COM 5K that has taken repeated dumps after power line failures. The controller is running off an Astron 35A supply. By dump I mean the only problem is that the controller has to be re-programmed after the AC power line failure. Now I know there are other ways than than the 13.5V for a glitch to get into the controller but I would suggest power to be the most likely. The battery to hold up the memory has been replaced.
Has anyone had the same experience with that controller's problem? I am going to try a diode in series with the power line shunted with a few thousand microfarads from the controller power input to ground. This should give a number of seconds of hold up while junk may be coming down the DC power line. Any other suggestions? It takes more than a four wheel drive to get to this site so this is a killer problem. Gran K6RIF
