Misfeatures fixed

For the Minnesota QSO Party, duplicate tracking and scoring was broken due to the rule forcing several distinct modes into either CW or SSB. Now, SkookumLogger will accept only those two modes for logged a QSO, and you must manually change other modes according to the rule. Also, some errors in Cabrillo output have been corrected. Thanks AF8A.

SkookumLogger delays starting a CQ message in 1T1R or 1T2R when it is triggered while Pounce has focus and the Pounce band is different from the Run band, in order to prevent transmitting while the radio is changing bands. A borked implementation was leading to introducing the delay when it wasn’t needed.

When using the keyer in the YCCC SO2R+ Box, toggling from Pounce to Run automatically to start a CQ aborted the CQ message after the first dash. Thanks GØDVJ.

When using the keyer in the YCCC SO2R+ Box, tapping the paddle to abort a message didn’t clear the message queue.

The latest version of SkookumLogger is available free of charge for download here.
