60-M AND TRANSVERTER ADAPTER

Assembly and Operating Instructions

Introduction

The K60XV adds 60-meter ham-band coverage to the K2 and K2/100 transceivers. In addition, it provides
a low-level (0 dBm) split-path interface for use with transverters such as the Elecraft XV Series.

60 Meters

60 meters is an interesting alternative to 40 and 80 meters. It's a useful band for field and emergency
communications, and has been adopted by the "HF Pack" group for nighttime calling. But the band has an
equally interesting set of limitations. In the U.S.: USB only, five fixed channels, and maximum power
equivalent to 50 watts into a dipole. Revision 2.04 K2 firmware allows the operator to quickly hop among
the five fixed channels, as well as do channel-based scanning. The KPA100 option can be also used on 60
meters, but units shipped prior to March, 2004 will require modification (see page 2).

Transverter Interface

The transverter interface allows the K2 to be used with VHF/UHF/microwave transverters that require
separate receive and transmit connectors. Such transverters generally require a low-level I.F. signal. The
K60XV's low-level output is nominally 0 dBm (1 milliwatt), adjustable using the K2's POWER control.
More importantly, the K60XV provides full closed-loop ALC that works in both SSB and CW modes.
Control outputs are provided for use with third-party transverters, including an open-drain keyline and three
band-select logic outputs (neither are required for use with Elecraft's XV Series transverters).

Revision 2.04 K2 firmware provides a number of transverter-related enhancements, including up to six
transverter bands, 0.1-mW increments on the bar graph, 0.01 mW units on the LCD in TUNE mode, and
user-programmable transverter addressing (to allow more than one band display to be used with each
transverter). With the K60XV installed, each transverter band display can be individually programmed to
use the low-power/split-path interface or the K2's normal high-power output.
