this frequency set was causing CAT command rejections on some Icom
rigs when using WSPR auto tune-up with the rig's built-in auto-ATU
anabled. The issue relates to a PTT-set, tune, PTT-reset,
set-frequency sequence where the rig's ATU is still tuning while the
PTT is reset. Since this should only happen in WSPR mode where split
operating is not used it should resolve the issue.
Using a local event loop to wait for Omni-Rig to initialize has caused
issues elsewhere, reverted to simple waits in teh hope that Omni-Rig
initializes promptly.
RIGCTRL is defined as a log channel for rig control messages and the
appropriate logger is made available to children of the Transceiver
class. Use Transceiver::logger() to access the logger.
Switched existing rig control QDebug messages to Boost logging.
