[DogParkList] Mac Doppler registration..

[Dave hartzell]

Hi Don-

A few years ago, I registered MacDoppler, probably under my old
callsign, N0TGD.

I'm back on a Mac, and I'd like to use the software, is my key still
valid?  It is probably associated with either this email
(hartzell at gmail.com) or possibly my NASA work email.

Thanks,

Dave
