Menu
Holding M E N U enables the menu function to allow the following parameters to be set. With the menu
function enabled, the MENU, EDIT and switches next to the and symbols all respond to a simple tap. Use
them to scroll through the menu items. Tap
E D I T and then the and switches to select the parameter and
tap M E N U again to save the parameter. Tap M E N U to exit the menu.
To reset all the parameters to the default value, press and hold the E D I T switch while tapping the O N switch to
turn the KPA500 on.
Menu Entry Default Description
ALC THR 210 ALC Threshold Adjustment: 0 to 210. See Using ALC on pg 17.
ATTN REL 3 Attenuator Release Time: 1.4 – 5 seconds.
BAND CHG NOR
NOR: OPER/STBY status the same after band change.
STBY: Switches amp to standby after band change.
DEMO NOR Factory Use Only.
FAN CTL NOR
Sets minimum fan speed.
NOR: fan is off when not needed.
1 to 6: selects various minimum speeds. Fan speed increases automatically as needed for
cooling.
FW REV Displays firmware revision.
INHIB IN DISABLE
ENABLE allows the amplifier operation to be inhibited (won’t amplify) when a logic low is
applied to pin 11 of the AUX Connector (see pg 26). When amplification is inhibited, an
underscore instead of the asterisk appears on the left end of the LCD display.
LCD ADJ 30 LCD Contrast Adjustment.
LCD BRT 6 LCD Backlight Brightness. Use DAY in bright sunlight. 2 to 8 for indoor lighting.
LED BRT 6 LED Brightness.
PWR ADJ 100
Per-Band Wattmeter Calibration, range 80 to 120. These are percentages of the measured
value.See Wattmeter Calibration Procedure on page 22.
PWR ON STBY
STBY: Amp is in standby mode when first turned on.
OPER: Amp is in operate mode when first turned on.
RADIO K3
Specifies driving transceiver interface:
K3: Allows use of Auxbus interface which allows the KPA500 band switches to change bands
on the K3; sends KPA500 mode to the K3 so the K3 can automatically select correct drive
power when the KPA500 is in OPER (see 16); reports KPA500 faults to K3.
BCD: Signals provided by Yaesu transceivers.
ANALOG: Signals provided by Icom transceivers. Note that Icom transceivers do not identify
WARC bands, but KPA500 frequency sensing will switch the KPA500 to the correct band
upon transmit.
SERIAL: Kenwood/Elecraft compatible interface using RS232X port. If transceiver is in split
mode, the transmit frequency will select proper band at KPA500.
RS232 P 38400 PC Serial Port Speed: 4800, 9600, 19200, 38400 bps
RS232 X 4800 Transceiver Serial Port Speed: 4800, 9600, 19200, 38400 bps. Set RADIO to SERIAL.
SER NUM Displays the unit serial number.
SER POLL N/A
ON: Enables KPA500 polling of the transceiver for frequency band via RS232X port (e.g. for
Kenwood/Elecraft compatible interface). Note: RADIO menu entry must be set to SERIAL.
OFF: Other device (PC, etc.) polls transceiver for frequency band.
N/A: RADIO menu not set to SERIAL.
SPEAKER ON Speaker (fault annunciator) ON or OFF.
TR TIME 0
QSK Delay Time: 0 to 50 ms; Slows T/R release time for transceivers with poor transmit
timing characteristics.
