In-line AT while receiving

The internal antenna tuner can also be

 

 

 

used during RX. Depending on

 

 

 

conditions, sensitivity can vary by

 

 

 

enough to see a change in the

 

 

 

S-meter. It can also reduce

 

 

 

low-frequency interference.

External AT control method

If you own an AT-300, you can connect

 

 

 

it to the TS-480; however, operation is

 

 

 

limited by the capabilities of the

 

 

 

AT-300.
