POTA Logger is written in Delphi 7. This is a logging program I have written for when I do my Parks On The Air activations. The program has an AutoSave function that saves all the logged QSOs into an ADI file. This happens every 10 seconds. The Export to ADI function is auto named to the correct syntax for immediate submission. Also, the time field keeps the current Zulu Time without the need for pressing an update button. This is a stand alone Windows exe that does not require installation. This program could easily be ran from a USB drive. It has had success running on some flavors of Linux and Mac by using wine.
Note: Some Antivirus companies flag this program with a false positive detection. You may need to add an exception in order for this software to run.
