OPERATION 

The  tuning  procedure  for  the  FTV-901R  trans­

ver ter  is  no t complica ted.  Howe ver, c are should be 

exercised  in  tuning  so  as  no t  to exceed  the ra tings 
of  the  transver ter and HF  transceiver. I t  is assumed 

tha t  the  proper  in terconnec tions  have  been 

performed, as described on  page 7. 

INITIAL CHECK 

Before  connec ting  the  FTV-901 R  to  the  power 

source,  confirm  tha t  the  AC  power specifi ca tion is 

correc t  for  the  supply  voltage  used, and  th a t  a fuse 
of  the  proper  ra ting  is  installed. Check all swi tches 
for 

normal 

operation.  Recheck 

the 

in ter­

connec tions  be tween  the  HF  equipmen t  and  the 

transver ter. 

The  following  discussion  is  tailored  to  a  fully­
equipped  FTV-901 R,  including  the  50  and 

430  MHz  uni ts.  The  reader  should  no te  tha t  these 

are  op tional  uni ts  on  the s tandard FTV-901 R. The 

word  "op tion"  will  hereafter  be  omi tted  in  the 

in teres t of brevi ty. 

F REQUENCY  SELECTION 

The  opera ting  frequency  is  de termined  by  the 
posi tion  of  the  main  tuning dial and  bandswi tch of 

the  HF  transceiver,  as  well  as  the  posi tion  of  the 
transver ter  band  swi tch.  Please  refer  to  the 

frequency char t below.
