[Elecraft] N6TV Product Announcement - new "K-ON" plugin for K3, K3S, and K4

[Bob Wilson, N6TV]

Thanks to circuit design help from K9JB, and after review by Elecraft Chief
Engineer, N6KR, I'm now able to provide a new plugin module for
the Elecraft K3 and K4 that I call the "K-ON".

When connected to the rig's ACC jack directly, or via a 15-pin Y-cable or
Y-BOX <https://bit.ly/Y-BOX>, the rig will automatically power up whenever
the rig's DC power supply powers up.  This could be useful to remote
stations with Internet-accessible AC power strips.  I also find it useful
at my home station where I use a "Master Power On" switch that powers
everything up automatically, including two K4Ds.

If you already have a Y-BOX with an unused connector, the K-ON plugs right
in.  I'm also including the same circuit inside the new Y-BOX v4.0 (so the
plugin is not needed).  The "Auto On" feature of Y-BOX v4.0 can be enabled
or disabled by a shortened RCA plug, as shown in the third demo video on
the website.

For photos, demo videos, and ordering one or more K-ON plugins, please
visit the new website.

Unlike some solutions that have previously been suggested, such as
connecting a big capacitor to ACC Pin 8, connecting the K-ON plugin has no
surprise side effects.  The rig's POWER switch and PS0; commands continue
to function normally, so the rig shuts down properly while the module
remains connected, as shown in the videos.  You can still connect a
RemoteRig box in parallel with no issues either; it will still function
normally.
