[Elecraft] RPN Calc App For Android

[Wes]

I have a working HP25 out in the garage/workshop.  The battery pack expired long 
ago and I pried it apart and put some Ni Cad cells in it.

I have a 15C in the shack.

I had another one, HP41C I think, that failed.  I can't find it so I think I 
finally threw it away.  Didn't like it anyway :-)
