FRONT PANEL CONTROLS

AND

SWITCHES

(1)

Meter

The

meter

provides

indication

of

SWR or

power

level.

(2) SWR SET

This

control

sets

thé

sensitivity

of

thé

SWR

meter.

Function

Switches

REF/FWD

This switch sélects

forward

or re-

flected

power

indication

on

thé

meter.

sélects

indication

of

thé

output power

level

scales:

15 or

150

watts

full

scale.

(4)

TUNE

The

TUNE control drives

a

variable capacitor

which

provides capacitive adjustment

of

thé

coupl-

ing

between

thé

transmitter

and

thé

impédance

established

by

thé

BAND

switch

and

LOAD

control.

The

TUNE

and
