portable  shortwave  receiver.  Table  I is a 
timeline of the 17 Heathkit GC receivers. 
By  the  late  sixties  the  Japanese  radio  inva-
sion  was  making  competition  difficult  for 
Heathkit. After 1969 Heathkit released only 
two  new  GC  receivers,  the  SW-717  in  1971 
and the SW-7800 in 1984, both solid-state. 
The  Heathkit  SW-717  General  Coverage 
Communications Receiver: 
Figure 1 is a photo of the SW-717 receiver. It 
first appeared in the second half of-1971, too 
late  to  make  the  main  1971  catalog.  In  the 
1972 catalog

that came out late in 1971 the 
SW-717  sold  for  $59.95.  An  accessory  long-
wire  antenna  kit  (GRA-72)

  sold  for  $2.95. 
By 1976 the price had started to rise: 1976 - 
$69.95,  1977  -  $74.95,  1978  -  $77.95,  1980  - 
$99.95. The last price found is $119.95 in the 
Christmas  1981  catalog.  Meanwhile  the  ac-
cessory long-wire  antenna  went up  to $4.50, 
and  in  1981  to  $7.95.  When  the  SW-717 
stopped  production  Heathkit  would  not  put 
out  another  GC  receiver  until  1983  when  it 
introduced  the  multi-hundred  dollar  synthe-
sized SW-7800 shortwave receiver. 
The SW-717 is a tabletop sized radio measur-
ing  14-1/2”  W  x  5-3/4”H  10”  D.  It  is  a  basic 
radio with  few  frills. It  covers  the broadcast 
band and up to 30 MHz in four bands clearly 
marked  on  a  slide-rule  dial.  The  I-F  uses 
three  455  kHz  ceramic  filters  instead  of  I-F 
transformers,  which  alleviates  the  need  to 
align  the  I-F  stages.  It  has  an  S-meter  that 
gives  relative  signal  strength.  The  SW-717 
specifications are shown in Table II. 
The SW-717 Front and Rear Panels: 
The  front  panel  has  six  controls,  two  slide-
rule  dials,  a  1/4”  phone  jack  for  earphones 
and a small S-meter marked SIGNAL with a 
graduated  scale  marked  0–5.  A  large  black 
plastic  slide-rule  dial  plate  with  green  and 
white  markings  covers  about  70%  of  the
