DEM TIK2
Universal Transverter Interface for the Elecraft K2
CIRCUIT DESCRIPTION
The new DEM TIK2 transverter interface is designed to be installed in the Elecraft K2
transceiver. The kit comes complete with everything required to connect the interface to your
transverter utilizing the IN XVTR OUT and the AUX I/O pre-punched holes in the K2’s enclosure. All
wiring , connectors, and switches are included in the kit for any possible configuration you require. You
will not need to drill any extra holes in the case!
The TX drive level
delivered through the
XVTR OUT connector is
nom3 dBm . The
RX signal from a transverter
is connected to the XVTR
IN avoiding the use of the
ANTENNA port. Using these
IF connections (IN XVTR
OUT) for transverters has
many advantages. There is
no need for an attenuator
in the TX line to “Pad” the
drive level. This in turn
saves energy which can be very helpful if using the battery pack. It also eliminates stray 10 Meter RF
radiation that will occur with poor quality attenuators. It will also eliminate the need for a extra relay to
separate the TX and RX lines to by-pass the attenuation on receive or the need for the separate Elecraft
RCV.ANT option in the K2.
The TIK2 connects internally to
the J-13 connector and may be installed
with all other K2 options. It can provide
any possible IF or keying configuration
required by your transverter system. The
interface has a manual enable/disable
switch installed in the INT.BATTERY
position. When enabled, the interface
bypass’ and removes the bias from the
final amplifier in the K2, This prevents
the transceiver from transmitting on 10
Meters and wasting DC power when the
transverter is in use. This switch also
allows instant switching from transverter
operation to transceiver operation.
