RTTY Filter
• The transceiver has 5 RTTY filters in
addition to normal IF filters. The
passband width can be selected from 1
kHz, 500 Hz, 350 Hz, 300 Hz and 250
Hz.
– When the RTTY filter is turned ON, the
RTTY tuning meter can be used.
• Moreover, the twin peak filter changes
the receive frequency response by
boosting 2 particular frequencies (2125
and 2295 Hz) for better copying of
desired RTTY signals.
