⑥
BAND-AUTO/MANUAL
To select band switching methods AUTO or MANUAL. When
using AUTO, the manufacturer for the transceiver in use should be
selected. When the band data cable is not used, MANUAL should be
selected. (See page 19, 10 Operation / Setting)
⑦
BAND-MANUAL
Rotary switch for band change in the manual mode. While the
transceiver is on Receive (RX) mode, turn to select the desired
frequency band operate. The switches will not work when the
transceiver and the amplifier are in Transmit (TX) mode.
⑧
METER (PF) Meter to read forward output power, PF. Full scale
is 2.5 kW, and it reads average power.
⑨
MULTIMETER
Pr (Reflected power from antenna), VD (FET drain voltage), ID
(FET drain current) and ALC voltage are shown on the scale as
selected by
④
MANUAL select switch. Full scales are; PR: 250W,
VD: 60V, Id: 80A, ALC: -10V.
⑩
ONAIR, FAN, ID, PROT (LED)
ON AIR : Lights when the amplifier is in transmit (TX) mode.
FAN : Lights when cooling fan is running at high speed.
When the heat sink temperature reaches 35
℃
, cooling
fan speed will continuously increase to enhance cooling
capacity.
ID : Excessive ID Indicator (55A). Depending on the
band and antenna situation, high drain currency may flow into FET’s.
If 55A is exceeded, this LED lights to indicate that high ID is being
drawn (This light does not necessarily mean a failure of the amplifier.
However, if it lights too often, or too long, it is possible the drive
power should be reduced and the antenna should be checked for
SWR, to avoid stress to the FET’s)
PROT : Lights when protection circuit shuts down the
amplifier. Various protection circuits are built in such as Over-drive,
Band mis-set, high Ant-SWR, Over-temperature etc. Detailed
explanations will follow.
⑪
LCD PANEL Displays modes of operation and protection circuit.
Detailed explanation will follow.
