Introduction
The KAT500 Automatic Antenna Tuner is designed to be closely integrated with the Elecraft K3
transceiver and the Elecraft KPA500 amplifier although it may be easily used with other transceivers and
amplifiers. Features include:
 Automatic band switching, covering the spectrum from 1.8 through 54 MHz.
 Automatic antenna switching to connect one of three antennas according to the band selected.
 L and C settings for lowest SWR are stored in memory for extremely rapid frequency and band
changes.
 Robust self-protection circuits that guard against damage from switching high-power RF or trying
to match loads outside of its tuning range.
 Static bleed resistor built in to avoid damage from normal static buildup on antennas.
 Low profile enclosure that matches the footprint of the KPA500 and K3, allowing the KAT500 to
be placed on top or under either unit (the KAT500 is designed to support the weight of the
KPA500).
If you purchased your KAT500 as a kit, turn to page 23 for assembly instructions.

Customer Service and Support
Technical Assistance
You can send e-mail to [email protected] and we will respond quickly - typically the same day
Monday through Friday. Telephone assistance is available from 9 A.M. to 5 P.M. Pacific time (weekdays
only) at 831-763-4211. Please use e-mail rather than calling when possible since this gives us a written
record of the details of your problem and allows us to handle a larger number of requests each day.
Repair / Alignment Service (We want to make sure everyone succeeds!)
If necessary, you may return your Elecraft product to us for repair or alignment. (Note: We offer
unlimited email and phone support to get your kit running, so please try that route first as we can usually
help you find the problem quickly.)
IMPORTANT: You must contact Elecraft before mailing your product to obtain authorization for the
return, what address to ship it to and current information on repair fees and turnaround times. (Frequently
we can determine the cause of your problem and save you the trouble of shipping it back to us.) Our
repair location is different from our factory location in Aptos. We will give you the address to ship your
kit to at the time of repair authorization. Packages shipped to Aptos without authorization will incur an
additional shipping charge for reshipment from Aptos to our repair depot
.
