On ebay: BC-15A WW1 Military Aircraft Spark Transmitter:

That is SO cool! I'm sure it's worth the starting price, but too rich for
me. Amazing that they had SPARK in airplanes - what would have
been the receiver? Surely a coherer detector... but maybe not???

This piece should be in a museum....

There may not have been a receiver, a lot of early aircraft wireless was
one-way, for reporting fall-of-shot for artillery etc.

BC14 crystal receiver.

BC14 crystal receiver.


Yes but not in the plane. These were used for spotting
and were only one way transmissions.

I had a BC-14A made by Deforest that I sold to a collector
that lives in Italy. Too bad for me, it's wroth about 3 or 4 times
what I sold it for then.
