The operating mode is selected
using the [MODE] buttons to the

which the selection is applied is
selected by the [A] or [B] button
above the [MODE] buttons. Usu-

If you reduce power using the [RF PWR] knob, the
ALC meter reading will increase; this is normal and
does not indicate any problem whatsoever (because
increased ALC voltage is being used to lower the

ERMINOLOGY
:
Semi-break-in
This is a pseudo- “VOX” mode used on CW, whereby
the closure of the CW key will engage the transmitter,
and release of the key will allow the receiver to re-
cover after a short delay. No signals will be heard be-
tween the spaces between dots and dashes (unless the
sending speed is extremely slow).

cover after a short delay. No signals will be heard be-
tween the spaces between dots and dashes (unless the

Full break-in
Full break-in (Also known as “Full QSK”) involves
very fast switching between transmit and receive, such
that incoming signals may be heard between the dots
and dashes as you send them. This allows you to hear a
station that suddenly starts transmitting on your fre-
quency, while you are in the midst of a transmission.
