This is the one... buy it!

After getting back on the air after five years, I decided to get with it and go to electronic logging. My ol' Icom 751A has the capability to provide rig control information, so thought I'd give Aether a try. After an unsuccessful attempt to get the frequency and mode to work, I emailed the author, Andrew Madsen. To my surprise, I received a quick reply with instructions on how to invoke the debug log and send it to him for his review. By the next day I had a new beta with rig control working. Now, that's support!

The application performs very well, has lots of features (see aetherlog.com) and makes logging a breeze. It even works perfectly well for contests.

Other apps for the Mac are more expensive, way overkill with features, and in my case didn't even work with my rig. If you want good software, written by someone who cares, is appropriately priced, and has superior support, look no further... it's Aether.
