Description
ATU SIDE
(Tech Mode Only)
—
The ATU uses a series inductance with a shunt capacitance on either the
source (TX) or antenna (ANT) side. Use the the
and
keys to
manually switch the shunt capacitance into the TX or ANT side of the L-
network inductance.
Normally, the ATU selects the correct side automatically.
ATU
STOP TUN SWR
(Per Band)
1.2:1
When an
ATU HiSWR RETUNE
is started, up to 31 stored ATU settings
and the current or near frequencies are examined.
ATU STOP TUNE
SWR
tells the ATU when an acceptable match has been found.
If an acceptable ATU setting is found, the search stops.
If SWR is not low enough, a NO MATCH fault may occur (see
ATU NO
MATCH SWR
menu item), and you should tap the KPA1500 front panel
ATU TUNE switch to start a Full Search Tune.
ATU XCVR KEY
(Tech Mode Only)
ON
Used when a K3
S
/K3 (MCU version 5.93 and later) is connected with an
AUX cable. When ON, the KPA1500 sends an AUXBUS message when
needed for TUNE POWER (carrier) for the ATU to complete tuning.
The KPA1500 sends another message to stop tuning.
Also used when performing an
ATU HiSWR RETUNE
or a Full Search
Tune (press of the front panel ATU TUNE switch).
BANDCHANGE->STBY
NO
Chooses whether to switch from OPER to STBY when changing bands.
YES
will switch the KPA1500 to STBY when changing bands. Useful if
you use a manually operated external antenna tuner.
DEMO MODE
(Tech Mode Only)
OFF
Used only for non-transmitting demonstrations where proper mains power
is not available. When keyed shows nominal SWR and full power output
even though no RF is being generated.
FAN SPEED MIN
0
Sets the minimum fan speed on the RF deck independent of heat sink
temperature
.
This setting does not affect the power supply fan.
FIRMWARE VERSION
—
Displays the KPA1500 firmware version.
LCD BACKLIGHT
7
Adjusts the brightness of the LCD backlight from 0 to 50.
LCD CONTRAST
23
Adjusts the contrast of LCD characters from 0 to 50.
LED BRIGHTNESS
22
Adjusts the brightness of the front-panel LEDs from 0 to 50.
NET GATEWAY
(Tech Mode Only)
—
Shows the IP address of the router as provided by a DHCP server when
the KPA1500 is connected to a TCP/IP network. Leading zeros are
removed from each octet.
NET IP ADDRESS
(Tech Mode Only)
—
The network IP address assigned to the KPA1500 by a DHCP server.
NET MAC
(Tech Mode Only)
MAC
Displays the unique media access control (MAC) address assigned by the
microcontroller manufacturer.
NET MASK
(Tech Mode Only)
—
DCHP-assigned Subnet Mask in dotted octet format.
NET WAKE on LAN
(Tech Mode Only)
ENABLED
KPA1500 will turn power on when a Wake on LAN “magic packet” with the
amplifier’s MAC address is received on its LAN Ethernet connector.
PEAK HOLD
(Tech Mode Only)
1.2 SEC
Power bargraph peak hold time, adjustable between 0.1 and 9.9 seconds.
POWER ON MODE
STBY
Selects whether the amplifier powers on in OPER or STBY mode.
RADIO POLL
OFF
ON
enables KPA1500 polling of the transceiver frequency via
XCVR
SERIAL
port. Applies only when
RADIO TYPE SERIAL
is selected.
