Let's be honest here: the inteface is awful.

Screen refreshes are slow and obvious. Selecting a drop-down item often leaves parts of the UI in the user area. Modes often leave the main window area in an odd state, and some modes (SSTV, FAX) seem to not be able to figure out how big the space that they have really is.

The UI is ugly and nearly unusable.

However, if this product actually reliably did what it says it does, then we could partially forgive the ugly UI. The fact is, it doesn't work with modest equipment. It can't lock onto machine-driven slow CW. It cannot see most RTTY traffic. With PSK31 it outputs less and less the closer you tune in. It couldn't even sort out the CHU timecode, and I'm so near a CHU station I can hear the data bursts in my fillings!

Maybe it was my rig (A top of the line SW receiver with a line-out to a *very* good PCI mixing console) but nothing worked as it should. Perhaps if the UI was more responsive I would have been able to tune in the various modes more reliably.

It is clearly alpha/beta release for OS X, and needs to be priced accordingly.

There are some marginally useful docs on the author's website.

Give it a try and see if it works for you. The product is nagware only.
