USING COMBINED FILTERS
1. When both LOW and HIGH 1 filters are engaged, the
pass bandwidth ranges.from
500
Hz to
3
kHz.
2. When both LOW and HIGH 2 filters are engaged, band-
width is
500
Hz to
1.5
kHz.

USE OF FILTERS
In general, it is desired that a CW, AM, or similar trans-
mission be received clearly within the usual communica-
tion audio bandwidth,
300
Hz -
3
kHz. However. QRM,
QRN or RFI may lower the overall signal-to-noise ratio at
the receiver, resulting in degraded reception. In theory, as
the pass-band width of the IF stages is narrowed, the equi-
valent
noise bandwidth will also narrow, thus improving
the signal-to-noise ratio. Alternately, the bandwidth of the
AF stage can be narrowed to attenuate the noise com-
ponent, enhancing reception.
Proper filter selection depends on transmission mode
and type of noise encountered.
1. SSB: use the HIGH 1 and LOW filters, or the HIGH 2
and LOW filters. In more severe cases, use both HIGH 1
+ HIGH
2,
and LOW filters.
2. CW: use the HIGH 1 and HIGH 2 filters or HIGH 1 +
HIGH 2 and LOW in combination.
