Why I Target OS X 10.6.8

OS X has come a long way since OS X 10.6.8; among the pluses: better multiple monitor handling, considerably improved memory management (part of which was fixing the leaks in the color management pipeline that OS X 10.6.8 exhibits) repairs to the bugs in 10.6.8′s CUPS printing system, and so on.

So why, then, target OS X 10.6.8?

SdrDx 2.13b beta posted

This version: Changes the behavior of the shifted cursor keys and the quick tune buttons at the top of the GUI such that the spectrum and waterfall will scroll when the demodulator bar approaches the span edges.

Also has new variable RF mute TCP command, rmute:X Y where X is either 0 (mute off) or 1 (mute on) and where Y varies from 0.0 (fully muted) to 1.0 (fully unmuted.) This allows you to drop the RF levels coming in any arbitrary amount for any reason. This is not sticky; on restart, rmute is set to 0 and 1.0.

Something for you CW types

You know, I have to confess: CW isn’t my favorite operating mode. It’s ok; sometimes I tune down to the CW portions of the ham bands and copy it for a while just to keep my hand in, but not too often. Consequently, another confession: I’ve not looked really hard into SdrDx’s CW handling until today. When I did, I found there were improvements that could be made, and, because I’m somewhat compulsive, I went ahead and made them, and you’ll find them in the 2.12r OSX beta that’s available for download as of right now. But don’t stop reading yet, please.

My old J-38 straight key

The first thing I did was some work on the high and low adjustment ranges of the CW mode demodulator envelope; CWL now allows from -10 to -1500 Hz, CWU allows from 10 to 1500 Hz. These are sane ranges; previously, it was a little weird, and I apologize for that.

The second thing was change the demodulator envelope adjustment from 100 Hz/step to 50 Hz/step. This allows you to create a properly centered demodulator envelope of an odd width, such as 300 Hz, or to cut the bandwidth all the way down to 50 Hz — a little extreme perhaps, but amazingly usable if the received station is stable.

Lastly, I experimented a bit with the audio notches to see how to best tailor the audio, and I found that with the Q of a notch set to about the third hashmark from the right of the Q scale, the notch was narrow enough to sit right on the upper edge of the demodulator envelope. I’ll give a detailed example:
