New OSX version of SdrDx – 2.04

Recordings now store and retrieve dB offset for more accurate playback. Right-clicking DNR now turns it on and off without changing the intensity. DNR algorithm altered somewhat. CAR mode gets carrier shift capability. Right mouse button now moves backwards through meter models. AGC intercept is now 120 dB (default.) TDM filter improved, dedicated. Method for detecting FUNcube Dongle Pro altered to match Windows version, which had to change to work around a Win7 bug. Works fine either way under OSX. Fix for waterfall saves. Last, certainly not least, move to online documentation. New HLP button takes you right to the docs.

Online Docs for SdrDx

I am pleased to introduce online documentation for SdrDx. This marks a sea change, where we move from a text file, buried in the distribution, to a system where everyone is looking at the same document, one that is easier to read, to look at and in general to deal with. It includes a table of contents, an index, visual cues for user interface elements and so on.

The link is on the SdrDx page, and the next release of SdrDx will take you there directly.

Comments and corrections are welcome, of course.

Maxwell’s Daemon rolls over in grave, finds pea

So, perpetual motion… nah. Of course not. And therefore, no device can have an efficiency over 100%. Right? RIGHT? Well, apparently not. Follow that link. Read. Imagine the consternation of the scientist upon determining the first results. I’ve been smiling ever since I thought about it that way.

There, wasn’t that interesting? Physics is COOL. huh. huh.
