Band Switching
The KXPA100 automatically measures the frequency of the RF drive and selects the proper band.
The
PA KEY
input must be connected to the driving transmitter.
Important: The automatic band selection function is active whenever PA KEY is low (in transmit
mode) and overrides band selection made by any other means to protect the KXPA100 from damage
by wrong-band operation.
Transmitting
1. Apply a watt of RF drive and note that the
POWER (W)
LEDs {8} illuminate to indicate the RF
output power.
2. Increase the drive power and confirm that the SWR LEDs indicate less than 1.5 while the output
indicated by the
POWER (W)
LEDs increases. Up to 5 watts of drive is required to produce the
full 100 watts output from the KXPA100. If more than 5 watts is applied, enable the input
attenuator (3 dB ATTEN) {17} by sliding its switch to the ON position.
Important: Never exceed 10 watts of drive to the KXPA100 at any time.
