Both sides agree on the reason for this: "We have a perfectly good 
standard. You people over there weren't listening!"

## Down for off..and up for on.....now that IS intuitive. At least if you doze off, and your 
heads hits the various toggle switch's, then it shuts off! 

##  driving on the left side of the road is counter-intuitive also.  Most folks are right handed.
I can't shift gears with my left hand if I tried.  Ditto with dash controls,also with your left hand.
All my relatives are in the UK, and seem to have it sorted out.

## wiring vac  T/R relays so they are energized on RX, and de-energized on TX is another one that's odd.
Yeah, I know, direct the lightning bolt into the tube, instead of the RX portion of the Xcvr. I can make any vac relay
operate faster by speeding it up... but can't do anything to speed up the rls.
