More consistent and accurate processing of compund callsigns including recognizing the user's call in both base and fully qualified form, extracting reports from special type one and type two compound call messages. Ensure that "CQ DX" message prefixes are recognized and processd correctly. The cycle of double clicking through a QSO has been enhanced to recognoize the standard messages correctly and use the correct next message. The automatic transmission button "Enable Tx" now does what it says and does not double as a stop transmit button. This allows the current transmission to complete even if the automatic transmission feature is disabled. In line with this the "stop sending after a 73 message is sent" feature turns off the automatic transmission enable at the start of the sending of a 73 message and also the next message is now set up as the CQ message automatically in this scenario. A 73 message is now either a standard message containing the word "73" or any free text message containing "73" (not necessarily as a distinct word"). git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@5055 ab8295b8-cf94-4d9e-aec4-7959e3be5d79

WSJT-X implements JT9, a new mode designed especially for the LF, MF,
and HF bands, as well as the popular mode JT65. Both modes were
designed for making reliable, confirmed QSOs under extreme weak-signal
conditions. They use nearly identical message structure and source
encoding. JT65 was designed for EME (“moonbounce”) on the VHF/UHF
bands and has also proved very effective for worldwide QRP
communication at HF; in contrast, JT9 is optimized for HF and lower
frequencies. JT9 is about 2 dB more sensitive than JT65A while using
less than 10% of the bandwidth. World-wide QSOs are possible with
power levels of a few watts and compromise antennas. A 2 kHz slice of
spectrum is essentially full when occupied by ten JT65 signals. As
many as 100 JT9 signals can fit into the same space, without overlap.
WSJT-X offers a “bi-lingual” operating mode in which you can transmit
and receive JT65 and JT9 signals, switching between modes
automatically as needed. Displayed bandwidth can be as large as 5
kHz. If your receiver has as upper-sideband filter at least 4 kHz
wide, you can have all the typical JT65 and JT9 activity on screen at
once, available for making QSOs with a click of the mouse. Even with
standard SSB-width IF filters, switching between JT65 and JT9 modes is
quick and convenient. Be sure to read the online WSJT-X User's Guide.
