SSB  TRANSCEIVER 

GENERAL  DESCRIPTION 

T he model 

FT-101E/277E 

SSB T ransceiver i s  a  precision 

built,  compact  high  performance  transceiver  of  advanced 

design  providing  SSB  ( USB,  LSB  selectable ),  CW  and 

AM 

modes  of  operation.  T he  transceiver  operates  at  an 

input  of 

260 

watts  SSB, 

180 

watts  CW  and 

80 

watts 

AM  on  all  bands 

1 60 

to 

1 0  

m eters. 

All  circuits,  except  the  transmitter  driver  and  linear 

am'plifier,  are  transistorized  and  com posed  of  standard 
computer  type 

plug-in 

modules.  permiting  easy  main­

tenance. 

The  tran'.'iceiver  is  sel f-contained.  req u i ri ng  only  an  an· 
ten na and an 

A.C. 

mains for home. portable or mobile oper­

ation.  The  transceiver  m ay  be  operated  from 

100/ 1 1 0/ 

117 /200/220/2 3 4  

volts  AC  when  appropriately  wired 

but  is  normally  suppl ied  for 

117 

volt  AC  and 

12 

volt 

DC  operation.  The  two-way  solid  state  power  supply 
is  an  integral  part  of  the  unit.  Two  power  cords . are 
provided  with  the  transceiver.  Selection  of  AC  or  DC 

power  source  is  automatically  made  w hen  the  proper 

line  cord  plug  is  inserted. 

For  mobile  operation  a  separate  switch  is  provided  on 
the  front  panel  to  turn  off  the  tube  heaters  while  in 

the  receive  mode.  In this mode the 

transceiver d raws only 

0.5 

amp .  less  than  your  auto  dash  lights. 

All  accessories,  such  as  VOX,  break-in  CW  with  side­

tone, 

25 

and 

100 

KHz  calibrators,  noise  blanker. 

10 

MHz  WWV  are built-in. In  addition  ,  dual VFO adaptor, 

crystal  control  adaptor,  speaker  and  clarifier  are 
integral  parts  of  the  unit.  Provision  is  made  for  the 
installation  of 

600 

Hz  crystal  filter  for  the  expert  CW­

DX  operator.  The  CW  filter  is  selected  automatically 
when  the  transceiver  mode  switch  is  placed  in  the  CW 

position. 
The entire transceiver weighs  approximately 

3 0  

pounds, 

is 

13  1/2" 

wide, 

6" 

h igh, 

11  1/2" 

deep.  Construction 

is  of  heavy-gauge  steel  which  provides  an  extremely 
rugged  package,  virtually  imm une  to  the  effects  of 
vibration  and  shock. 

1he  SP  101PB/277PB  combination  phone  patch 

and 

ex­

ternal  speaker.  is  a  valuable  optional  accessory  for  base 

operation.  The  unit  features  an  elliptical  type  speaker 
for  high  quality  voice  reproduct

on.  Other  optional 

equ ipment  includes  the  FV-1018/ 2 7 78  external  YFO 

and  mobi le mounting  br
