[Elecraft] new mini-modules: applications

[Don Wilhelm]

Kieth,

If the LED height over the other components is a concern, one could even
mount the LEDs on the back side of the board and the other components on the
front, although I suspect there is plenty of room - the transverters and
KAT100 front panel combine the LEDs with other (lo-profile) components on
the front side of the board.  I believe the real answer is: if it is too
tall, move it to the back side, each enclosure choice may have its own
considerations to deal with.

73,
Don W3FPR
