Notice to the user:
One or more of the following statements may be
applicable to this equipment.
FCC WARNING
This equipment generates or uses radio frequency |
energy. Changes or modifications to this |
equipment may cause harmful interference unless
| the modifications are expressly approved in the
instruction manual, The user could lose the
authority to operate this equipment if an
| unauthorized change or modification is made.
| Information to the digital device user required by |
the FCC:
This equipment has been tested and found to
comply with the limits for a Class B digital device,
|
Pursuant
to
Part
15
of
the
FCC
Rules.
These
limits
are designed to provide reasonable protection
against harmful interference in a residential
installation. This equipment generates, uses and
can generate radio frequency energy and, if not
installed and used in accordance with the
| instructions, may cause harmful interference to
[radio communications. However, there is no
guarantee that the interference will not occur in a
particular installation. If this equipment does cause
jharmful
interference
to
radio
or
television
| reception, which can be determined by tuming the
equipment off and on, the user is encouraged to
try to correct the interference by one or more ot
the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the
equipment and receiver.
— Connect the equipment into an outlet on a
| circuit different from that to which the
receiver is connected |
Consult the dealer for technical assistance.
WARNING
To prevent fire or shock hazard, do not expose
this appliance to rain or moisture.
General
Digital Signal Processing is a method of signal
manipulation that takes an analog signal, such as a
sine wave, and converts it into a digital waveform
that looks a lot like a staircase. By converting the
signal into a digital waveform itis possible to remove
‘some of the noise associated with the signal, and
also to tailor the audio passband of the transceiver
for the best performance.
DSP also has the advantage of providing increased
‘suppression of the unwanted sideband during SSB
operations.
It
increases
the
amount
of
carrier
suppression, provides an improved CW waveform
that may be tailored for operator preference of rise
and decay times, and provides a cleaner RTTY/FSK
signal that decreases errors.
Operator controls are provided on the front panel of
the DSP-100 to allow the operator to select 4
different LPF response limits and 4 different HPF
response limits. This is useful in pileups as it
provides maximum signal intelligence with minimum
bandwidth. Since the signal is also digitally
processed
this
results
in
a
signal
that
is
“cleaner
or
more crisp" than an equivalent analog signal. This
makes it easier for the DX station to pick you out of
the pile-up.
During marginal band conditions the ability to digitally
process the incoming receive audio signal can also
result in a cleaner signal. Since the processing is
done at an IF level it results in a more copyable
signal. Not only are you able to tailor the audio
frequency response, but because the signal has
been digitally processed it also appears to be
“cleaner or more crisp”.
