ï Meter peak hold
The meter peak hold function freezes the highest dis-
played bar segment in any meter function for about
0.5 sec. so that you can more easily read the meter.
This function can be turned ON and OFF in
initial set
mode
. (p. 31)
Initial reception of a signal
results in an S-meter reading
of 40 dB.
The highest indicated bar
remains displayed for 0.5 sec.
even when the signal strength
decreases.
The IF shift function electronically narrows the pass-
band frequency of the IF (intermediate frequency)
and cuts out higher or lower frequency components
of the IF to reject interference. The function shifts the
IF frequency up to ±1.2 KHz in SSB/CW/RTTY
modes and up ±250 Hz in CW-narrow/RTTY narrow
modes. The IF shift is not available in AM mode.
IF SHIFT OPERATION EXAMPLE
Adjust the [SHIFT] control for a minimum interfer-
ence signal level.
When IF shift is used, the audio tone may be
changed.
Set the IF shift control to its center position when
there is no interference.
