What changed in v0.26 ?
v0.26 adds a new FM Hellschreiber mode and a new set of fonts to support it. v0.26 also reduced processor use in Hellschreiber, improved thread behavior of HF-FAX, added new AppleScripts and controls for RTTY and fixed a bug when reading transmit echo streams back through AppleScript.
FM-Hell 105
Hellschreiber now supports a second narrower bandwidth FM Hell mode. You can now select either "FM Hell 245" or "FM Hell 105" modes.
Hellschreiber Fonts
Unlike Feld Hell and FM Hell 245, FM Hell 105 does not
support double bit fonts. A new font, "cm small" (and the
anti-aliased version, "cm small aa") is created.
"cm small" includes lower cased characters and lower case
characters have also been added to the original cocoaModem
Hellschreiber fonts ("cm bitmap" and "cm bitmap aa").
Reduced processor load in Hellschreiber
The Hellschreiber display is refreshed every time a column
of glyph is received. This presents quite a heavy processor
load on older Macintoshes. With v0.26, only the
neighborhood of the column that changes is refresh (except
when the text image is being scrolled).
Changes to HF-FAX
v0.26 has some changes on HF-FAX horizontal sync detector,
and also some thread changes to improve the behavior when
changes are made to the clock adjustment or horizontal
position of the image.
Wideband RTTY Transmit Tone Lock
You can now lock the transmit tones in the Wideband RTTY
Interface so that clicking on the waterfall only affects
the receive tone pairs. This is useful if you are in CQ
mode in a contest or operating as net control.
AppleScripts
AppleScript implementation to read back the transmitted
stream was left out in previous versions of cocoaModem.
Wideband RTTY was also not previously connected to
AppleScripts. They should now work.
Added "invert" AppleScripts to both receive and transmit
directions of the RTTY interface.
