What has changed in v0.30 ?

This version of cocoaModem has a new CW Interface.

The AudioInterface and CoreFilter frameworks and the AppleScript interface have been updated to add functionalities needed by the CW Interface.

The Contest Menu now includes an "ignore newline" option for received text.

Enabled the Hellschreiber waterfall's dynamic range menu which was left disconnected in an earlier release.



CW Interface

cwMenu

cocoaModem now has a Wideband CW interface.

The new interface allows you to click to a signal for instantaneous tuning to a CW signal that is within a waterfall's passband, and either listen to it at a selectable pitch on a pair of headphones, or if the signal has moderately good signal-to-noise ratio and well keyed, have it printed by a Morse decoder.

For transmission, an audio tone keyed signal is used to transmit a CW signal at the same pitch offset as the received signal to an SSB transmitter. Because of the speed requirements, you will need to use a non VOX-driven PTT to be able to transmit through the CW interface.

In addition to the usual AppleScripts to select the interface and to transmit and receive data streams, the AppleScript interface is expanded to include a "breakin" parameter for the CW interface.

Please read the manual before attempting to use the CW Interface since there are additional configurations that are not in the other interfaces.


Ignore Newline menu in the Contest Interface

newline

An Ignore Newline menu is added to the contest interface. If the menu item is selected, received newlines (linefeeds) will be converted to " - " (space, dash, space). This will reduce the jumping of the exchange view and should make call sign capture in a contest easier to perform.

The Ignore Menu item is not "sticky." You'll need to set it each time you relaunch cocoaModem and wish to ignore linefeeds.


Hellschreiber waterfall Dynamic Range bug fix

The dynamic range popup menu of the Hellschreiber waterfall was left unconnected. Fixed in this release.


Frameworks

Changes were made to the AudioInterface and Corefilter frameworks to support CW.
