CONTROLS AND INDICATORS
The front panel has two switches, eight LEDs and a ten segment LED bargraph. There are sev-
en 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 a valid
AMTOR data link.
STA/VAL - This LED will illuminate when you have unacknowledged HF packets OR a valid
AMTOR data link.
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
operating 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.
POWER INDICATOR - 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.
Ten Segment LED Bargraph:
The bargraph provides a visual indication of the received HF signal. The end segments, la-
beled MARK and SPACE, blink alternately on a properly tuned RTTY/ASCII/AMTOR or Packet signal.
In CW mode the bargraph illuminates from left to right. In addition, when your PTT line is being
keyed to transmit on the HF port, the LED bargraph will be blanked out.
