[Johnson] Caveat

[Robert Nickels]

For a company that made components - including connectors - EF Johnson Co.
couldn't seemingly make up it's mind whe it came to connectors on their ham
gear.   Everyone's struggled to attach antenna relays to that goofy crystal
socket and now I can add one more to watch for.  On the Invader, they went
to a round plug with 5-6 pins and a metal shell (like some old CBs used for
a mic connector) for the receiver mute contacts.  Problem is, there are two
of these sockets on the rear panel of the Invader - one for receiver muting
and another connects to the AC line.   And they're both the same, so it's
possible to do like I did today and plug the AC line into your receiver!
Fortunately for me all it did was blow the fuse, but the result could have
been worse.   So if you've got an Invader, remember the connector you want
is the one nearest the mic jack, NOT the one over by the line cord and fuse!
