[Elecraft] Items you think you can depend on

Tue Sep 5 16:24:02 EDT 2017

Before I left for college and from the time I was a VERY small boy, I
had a "military surplus collection" which included several packs of
"Lucky's".... two of which were still part of the rations packs they
came in.  <smile>
Additionally, my collection once contained a PRC-25....  <---- making
this radio related.  <wink>

Yes, there are many options at this point.  I have used the APC
(consumer and commercial) parts that both monitor/report line voltage
(some even quality in addition), AND regulate it if need be.
I also have a box full of non-networked monitors/loggers that simply
plug in between service and device.

I hope to have an active monitoring system at some point that observes,
reports, and can take remedial actions, but that's way down the list.
