The Rx meter is now a better Qt citizen and can be resized. Added a more obvious peak signal indicator. It is now a custom widget derived from QFrame and is now directly added via promotion in Designer. Added a custom widget to act as a letter spin box, this is used for sub mode control. Switched the frequency tolerance widget to a combo box with preset values so that it is more uniform across systems and font sizes. Added container widgets for group control of various UI widgets such as QSO controls, DX call controls and WSPR controls. Introduced a stacked widget to allow the WSPR controls to be swapped in in place of the "QSO" controls. The "QSO" controls are are the Rx, Tx and related controls along with the main tab widget with the message buttons and fields. This means that the WSPR version of the main window (and EME Echo mode) are now much cleaner. Increased the size of the rig control widget and styled its colour using a dynamic property so that it can be defined in the Designer UI definition. Reinstated it as a push button to do a rig control reset and retry after an error. Reset most UI widgets to default properties, particularly removing any fixed sizes so that they can resize freely when fonts are changed. The overall layout is now controlled almost exclusively by stretch factors on some of the rows and columns of the various grid layout managers. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@5630 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.
