For  usual  operation  place  this  control  in  the  “ R F ”   position  (füll  counterclockwise  position).

This  control,  placed  in  the  RF  position,  switches  in  the  “ RF  meter”  and  your transmitting  power 
will  be  indicated  on  the  RF  meter  scalę  (1  .  .  .  .  10),  while  the  push-to-talk  switch  is  depressed.

Another  use  of this  control  is  to  check  for  SWR  (Standing Wave Ratio) of your antenna system.  See 
“ SWR  Check”   in  this  manuał.

M O D E   SW ITCH  (USB,  USB  &  A M )

Controls  the  mode  of operation  for  the  transmitter  and  receiver  simultaneously  and  allows  sélection 

of  conventional AM  operation  or  SSB  operation on either upper or lower side band.  In order to com- 

municate. with  another  transceiver,  you  must  use  the  same  operating mode.

When  receiving  SSB  signais,  adjust  the  FINE  TUNE  knob carefully and fix it at such a position where 
the  incoming  signal  сап  be  heard  most  clearly.  Because  of  the  characteristics  of  an  SSB  signal,  it  is 
extremely  important  to  adjust  this  control.  With improper  FINE TUNING  adjustment, the  signal will 

not  be  intelligible.  The  sound  will  be  distorted.  SSB  tuning  will  become  easy  as  you  acquaint 
yourself with  the  operation  of this control.  After adjusting it to  clarify once, no adjustment is needed 
if you  stay  on  the  same  mode  and  channel,  receiving  the  same  station.
