Options and Modifications
The transverter is designed for the greatest possible flexibility when
integrating it with other equipment in a high-performance station.
It is Elecraft’s policy to encourage owners to experiment with their own
(careful) modifications. You can build-in accessories and make changes
to the circuitry if desired. However, this policy has one firm limitation: If
you make a modification other than those described below that damages
or alters normal operation, it may not be repairable by Elecraft.
Any personal modifications that you create should be installed in such a
way that they can be easily disabled (turned off, unplugged, etc.). This
will allow us to test and repair your kit if it becomes necessary. Repair
charges will be higher if our technician has to un-modify your
modification for any reason. Of course, any Elecraft-approved
modification, such as those described below, may be left in place should
you need to send in your transverter for repair. There will be no additional
charges caused by the transverter having any of these modifications. They
will not be removed by the Elecraft technician.
In addition to the options and modifications described here, check the
Elecraft web site at www.elecraft.com for the latest information about
using your transverter with the latest systems and station equipment.
 Optional Crystal Oven. Improves the stability of the local
oscillator by maintaining the crystal at a constant temperature.
 Changing Between Split and Common Antennas. Allows you
to configure your transverter for use with a common transmit and
receive antenna or with separate transmit and receive antennas.
 Reducing Receive Gain to Preserve System Dynamic Range.
Reduces the gain of the transverter receive circuitry to help
preserve the system dynamic range when an external preamplifier
is used.
 Optional Feet and Bail. Elevates the front of the transverter to a
convenient viewing angle.
Tools Required
Some of these options and modifications require soldering. We
recommend you use the following:
 Fine-tip temperature-controlled soldering station with 700 or
800
F tip (370-430C). Do not use a high-wattage iron or gun to
avoid damaging printed circuit board (PCB) pads, traces, or the
parts themselves.
 IC-grade, small-diameter (.031”) solder (Kester #44 or
equivalent).
 A good vacuum desoldering tool such as the Soldapullt® model
DS017LS.
i
DO NOT use acid-core solder, water-soluble flux solder,
additional flux or solvents of any kind. Use of any of these will void
your warranty.
In addition, you will need small hand tools including the following:
 Screwdrivers: a small, #2 Phillips and a small flat-blade for
slotted screws.
 Needle-nose pliers.
 Small-point diagonal cutters, preferably flush-cutting.
 Digital Multimeter (DMM) for voltage checks and confirming
resistance values.
