1. 

INPUT

 Continuosly adjustable input capacitor. Min. 

  capacitance = 0. Max. = 100.

2. 

DIRECT-TUNED MODE SWITCH

 Six-position rotary switch selects an 

output coaxial connector.

 a. 

DIRECT BYPASS

 selects BYPASS COAX CONNECTOR bypassing the 

impedance matching circuit, but providing SWR, FORWARD, and 

REFLECTED power meter readings.

 

 b. 

DIRECT COAX 1

 selects COAX 1 CONNECTOR bypassing the tuner 

matching circuit, but providing SWR, FORWARD, and REFLECTED meter 

readings.

 c. 

DIRECT COAX 2

 selects COAX 2 CONNECTOR bypassing the tuner 

matching circuit, but providing SWR, FORWARD, and REFLECTED meter 

readings.

 d. 

TUNED COAX 1

 selects COAX 1 CONNECTOR through the impedance 

matching T circuit.

 e. 

TUNED COAX 2

 selects COAX 2 CONNECTOR through the impedance 

matching T circuit.
