We had a major fiasco here in Cincinnati this Wednesday. In Ohio
March is Tornado Awareness month. We are the SW-OH LP-1 and we
were to relay the RMT alert from the state primary to all the stations in
this part of the state. All was going well, we received the test and were
in the process of repeating it out when the endec decided to reboot!
11 times! Of course it had sent the RMT header and 1 second of 2 tone
attention signal. then 30 seconds of silence. Of course the endec rebooting
put the program lines back to the air! The talent cautiously says "well
that did not go quite right" babbles something about that is why it is a test
and proceeds on with the show. On every radio and tv station in SW-Ohio!

Needless to say my voice mail was smoking. Here is a post mortem.
If you have a sage endec as allot of us do. REPLACE THE POWER SUPPLY!
50 percent of the Sage power supplies in Cincinnati have failed. That is what
was at the root of the above problem. They will all be replaced with the
modification below.

Here is what we have decided to do to fix the problem. Rather than
replace the power supply with the exact same part that will fail in two
years we decided to try to bullet proof the fix. We went to Radio Shack
(where else?) and purchased a model 22-504 3 amp power supply. It needs one
slight modification to do 15 volts. Open the supply and change r-10 from a
510 ohm to a 1000 ohm resistor. This lets you adjust the supply to 15 volts.

R-10 is alongside the voltage trimpot. We just cut the wire and plug off of
the old supply and put it on the terminals of the new one. Ours is White
stripe to the center plug which is +. Yours could vary so its best to check
it. As always, this is an at your own risk type of modification (that is to
cover my rear!).

Hopes this helps someone out.
