Problem solved!


if you do that make sure the switch is a DPDT center-off switch, or at a
bare minimum break before make. xfmrs can backfeed and that wouldn't be
safe

OK -- long, long ago *I* was a "ham" (but got bored because
all that the people talked about was their equipment. But
of course if I had *designed* and built my own transmitter,
I wouldn't be bored, but fascinated!)

So I know what a DPDT switch is OK.

But what's a "center-off" one?

Or, at bare minimum, a "break before make"? (Well, that one
seems self-evident. Question: aren't ALL dbl-throw switches
break before make? I guess not. Please elaborate.)


Thanks!

All NORMAL DPDT switches are break before make - some specialty
switches are make before break. A DPDT "reversing duty" switch HAS to
be break before make
