FRONT PANELS

Front Panels
KAM
The front panel has two switches, eight LEDs and a ten segment LED bargraph. There are seven
LEDs used as operating status indicators. The front panel is divided into two sections. The left
three LEDs are the indicators associated with HF operation, and the four right LEDs are the indica-
tors associated with VHF operation. The two segments are divided by a white color bar. Each LED
has the functions indicated below:
HF Section:
XMIT
– This LED will illuminate when the
KAM
is keying the PTT line on your HF radio OR when
HF packets are being received.
CON/LOCK
– This LED will illuminate when you have an HF Packet connection OR an AMTOR lock
condition.
STA/VAL
– This LED will illuminate when you have unacknowledged HF packets OR valid AMTOR
data.
VHF Section:
XMIT
– This LED will illuminate when the
KAM
is keying the PTT line on your VHF radio.
RCV
– This LED will illuminate when you are receiving a VHF packet.
CON
– This LED will illuminate when you have a VHF Packet connection. In addition, when operat-
ing non-Packet HF modes, this LED will blink ON/OFF for approximately 10 seconds if
KAM
receives
a VHF Packet connect request.
STA
– This LED will illuminate when you have unacknowledged VHF packets. Also, if the CON light
is OFF, the STA light is used to indicate PBBS status – ON steady indicates someone is connected
to the PBBS and blinking indicates mail in the Kantronics TNC for you.
POWER INDICATOR
POWER
- The single LED on the right end of the front panel illuminates when power is applied.
Switches
ON/OFF
– Provides power control of the
KAM
.
AM/FM
– Switches the limiters in or out of the demodulator circuits. This switch should be set to
AM for CW operation and FM for RTTY/ASCII/AMTOR. For Packet operation, either AM or FM can
be selected. Use the setting you prefer.
