7.2 HAM GEAR CW
In the development of this product, special attention was given to
design a product with excellent CW operation. Two key jacks are
provided; one for a straight key (mono jack) and the other for an
electronic keyer (stereo jack). The straight key allows the operator
full break in capability, and also the transmitter can be keyed by
using a separate foot switch or depressing the push button on the
microphone. The second jack is designed for operation with the
internal electronic keyer that preconditions the speed of the keying
from 5 to 60 words per minute. The software design is highly
sophisticated and has been acclaimed by many hard core CW oper-
ators. Power adjustment capability is provided from the front
panel; from 25 watts to below 1 watt. Accurate adjustment or read-
ing from the indicator is not supported. At 5 watts the reading may
be within plus or minus 1 watt and 15 watts it maybe within plus or
minus 2 watts. Higher deviation in some instances may be record-
ed and the operator can set his own table for the particular radio.
Combining the proper use of audio level, RF level, passband tun-
ing, audio frequency and bandwidth tuning, the CW operator will
enjoy superb CW communications world wide. From a home base
station or to the North Pole or the, Amazon jungle, the SG-2020
functions as a remarkable CW portable unit.
7.3 HAM AND COMMERCIAL DATA COMMUNICATION
The SG-2020 is well suited for data communication especially if
operated with modern DSP data modems such as the SG-7200 or
SCS PACTOR. This provides a well balanced combination for
efficient data communication. Most DSP data modems have a 12
to 20 dB signal to noise ratio advantage over an analog modem;
therefore power output of 1 to 20 watts is more than sufficient to
provide reliable world wide communications. Future developments
of the SG-2020 will be available with external power and frequen-
cy adjustments to allow adjustment of both elements depending on
the signal quality.
