[Elecraft] RPN Calc App For Android

[Fred Jensen]

The short ones [mine was a K&E] went behind the protector in my shirt 
pocket that housed 3 mech pencils ... #2, #4, and #4H ... plus a 
cartridge fountain pen.  I was never fond of the Al Picket rules, they 
seem to constantly produce incredibly fine Al dust on my hands, clothes, 
and notebooks.

In the mid-60's in SE Asia, just coming out of my bulletproof and 
immortal period, I had a Collins Radio circular rule for calculating 
tropospheric path parameters.  Don't remember where I got it and I was 
unaware that Collins was into tropo.  It went MIA on a mission somewhere.

73,
