4.1.4, RIT CONTROL
By using the RIT (Receiver Incremental Tuning) control. the
receive frequency can be shifted by about + 1.5 kHz without
changing the transmit frequency,
If the frequency of the station you are working changes, your
receive frequency can be reset by turning the RIT switch ON.
'and adjusting the RIT control. Adjusting the contro!
clockwise increases the frequency. The RIT shift can be
checked by the digital display. When first calling another
station, the RIT should be OFF. otherwise your transmit and
receive frequency will coincide,
4.1.5, IF SHIFT CONTROL
The IF SHIFT control is used to shift the passband of the IF
filter without changing receive frequency. By turning this
control in either direction, the IF passband is shifted as
shown in Fig, 4-3.
The IF SHIFT is effective in eliminating interference when
the receive signal is superinposed on nearby signals during
'operation in USB, LSB or CW mode.

CAUTION: ——$_________
Before transmitting, be sure to connect an antenna or dum:
my load with a VSWR of less than 1.5:1. Never attempt to
transmit with the antenna terminal left open,
