[Elecraft] 32 bit Elecraft Utility Apps

[Bill Frantz]

wsjt-x is quite CPU intensive. Running FT8, it has a lot of 
computing to do to decode the signals in the 3 second or so 
window it has. It is decoding multiple signals, and then 
reconstituting the decoded signals so it can subtract them from 
the input and decode the signals hiding underneath them.

Joe Taylor mentioned in a lecture that the decoded signals are 
listed in ascending order of frequency, and these second decodes 
appear at the end.

OTOH, wsjt-x appears to only need about 30MB of storage, so it 
should fit nicely in the 2GB address space it has on most OSes. 
It needs speed, not bit addresses.

BUT, with Linux distos moving away from 32 bit, and Apple 
announcing the end of support for 32 bit, if Elecraft wants to 
continue supporting these platforms -- and I hope it will -- 
they should move "with all deliberate speed" to supporting 64 
bit utilities.
