This  switch  will  be  used  to  check  the  SWR  (Standing  Wave  Ratio)  of  your  antenna  system.

SW R   C H E C K

1. 

Connect  your  antenna  system  to  the  antenna  conneetor  on  the  rear  panel.

2

.

 

Place  the  mode  switch  in  the  AM  position  and  the  CB/РА  switch  in  the  CB  position.

3. 

Place  the  CAL/SWR  switch  in  the  released  out  position.

4. 

Press  the  push-to-talk  button  on  the  microphone  and  rotate  the  RF-CALIBRATE  knob  so  that 
the SWR  meter pointer reads maximum or SET.  Release the push-to-talk  switch.

5. 

Depress  the  CAL/SWR  push  switch  and  agam  press  the  push-to-talk  button.  The  SWR  of  your 

antenna system  will  be  indicated  on  the  lower  scale.

SWR  readings  of  less  than  1.5  are  désirable,  and  usually  obtainable  with  modern  factory-made 

anten nas  in  good  condition.

Readings  up  to  2.5  may  be  acceptable,  but  readings  over  3.5  should  definitely  be  reduced  by adjust- 
ment o f the antenna system.

NOTE: 

After  completion  of  SWR  CHECK,  always  place  the  RF-CALIBRATE  Knob  in  the  RF
(full  со unter-clockwise  position)  position.
