Introduction

The K3 transceiver can accommodate up to five high-performance crystal I.F. filters of different bandwidths.
This manual covers the installation of additional filters to your transceiver.

Only a few basic hand tools are needed (see page 5) to perform the installation. No soldering or wiring is
required.

Customer Service and Support

Technical Assistance

You can send e-mail to [e-mail] 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 831­662-8345. 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 turn around 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
