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.

FMHELL 105



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

TxControl

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.
