[QCWA] Fw: microlog air-1

[Larry McCalvy]

Thanks Jeff for a very nice explaination. Sounds like a interesting program 
to use.

Gary, if you have no use for the AIR-1 and feel like hauling it to Denver, I 
would be most interested in taking it off your hands. We can discuss it over 
an 807 or two - my treat of course.

Thanks again Jeff for sharing the AIR-1 use.

73,

Larry
