The Swan ASTRO l02BX is a 160M through lOM SSBamateur transceiverthat
features dua1 PTO's and frequency counter for splitfrequency operation with
digital frequency readout. Frequency selection is the only tuning necessary
when operating into a matched antenna with a VSWR of 1.7:1 or less.
Standard features include: Full break-in or semi-break-in CW operation;
narrow band crystal CW filter; two position CW transmit pulse shaping; VOX;
noise blanker; SSB transmit speech processor; true RF and IF gain controls;
peak reading wattmeter with FWD, REF, and ALC positions; variable AGC decay;
passband tuning; and audio notch filter. The basic single conversion design
has been proven in thousands of the popular Swan transceivers. Mechanical
and electrical designs are exceptional, for years of trouble-free operation,
even in a rugged mobile environment.
The unit is designed for fixed and mobile use with minimum interconnec-
tions. For fixed station operation an auxiliary speaker/power supply, model
psu-6,
provides 13.6 V IC from 115/230 V AC. A matching antenna tuner, model
STZA, is also available.
The transmitter may be used for RTI'Y or Slow Scan TV, but operation in
these modes requires additional forced air cooling. See the operator's an-
ual for precautions to be observed when operatingin these modes. The ASTRO
l02BX includes automatic gain control (AGC) in the receive mode, and auto-
matic level control (ALC) in the transmit mode. CW sidetone is also provided.
