RIT control (TH-55AT/55E only)
When the transmit frequency of the distant station
drifts a little bit during the QSO, but you do not wish to
alter your transmit frequency to compensate, you may

trol allows shifting the receive frequency apploximate-
ly ±5 kHz without shifting the transmit frequency.
