Introduction
This is the assembly manual for the Elecraft XV50, XV144 or XV222
transverter kits. A separate manual covers the assembly of the Elecraft
XV432 transverter.
Full details of the Elecraft transverters including specifications,
installation, operation, circuit descriptions, options and modifications
available, troubleshooting and maintenance instructions are included in
the Owner’s Manual which accompanies this kit.
This is an intermediate to advanced kit, yet you'll be surprised at how
uncomplicated it is to build. All of the radio frequency (RF) circuits are on
one printed circuit board (PCB). A second smaller PCB holds the
microcontroller and front-panel LEDs. High-quality, double-sided PCBs
are used, with plated-through holes for optimal RF performance. Point-topoint wiring is minimal. All components to be installed have wire leads;
the few surface-mount devices required are pre-installed on the PCB.
This kit uses just one toroidal inductor, which is easy to wind. However, if
you prefer not to wind this inductor yourself, you can order one prewound with the leads tinned and ready to install from an Elecraft-qualified
source. Ordering information is on our web site at
www.elecraft.com.

Preparing for Assembly
Overview of the Kit
The Elecraft XV transverters use modular construction, both physically
and electrically. This concept extends to the chassis (Figure 1). Any
chassis element can be removed to provide access.
Figure 1. XV Transverter Modular Cabinet Parts.
There are two printed circuit boards (PCBs) in the transverter: the front
panel PCB, which sits vertically behind the front panel, and the large RF
PCB visible in the cover photograph.
The PCBs are interconnected using board-to-board connectors which
eliminates the need for a wiring harness. Gold-plated contacts are used on
these connectors for reliability.
Tools Required
You will need the following tools to build this kit1:
Fine-tip temperature-controlled soldering station with 700 or
800F tip (370-430C). Do not use a high-wattage iron or gun
since this can damage pads, traces, or the parts themselves.
IC grade, small-diameter (.031”) solder (Kester #44 or equivalent).
Desoldering tools and supplies are invaluable if you make any
modifications or need to do any repairs. Narrow solder wick or a
good vacuum desoldering tool such as the Soldapullt® model
DS017LS are recommended. See Soldering, Desoldering and
Plated-Through Holes, on page 6 for more information.
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.
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
resistor values. A DMM with capacitance measurement capability
is desirable, but not required.
Noise generator (Elecraft N-Gen or equivalent) or signal generator
with output in the RF frequency range of the transverter.
RF power meter capable of measuring RF power levels up to 25
watts at the frequency used by the transverter.
50-ohm dummy load capable of handling 25 watts, minimum.

Preventing Electrostatic Discharge Damage
Your XV transverter uses integrated circuits and transistors that can be
damaged by electrostatic discharge (ESD). Problems caused by ESD can
be difficult to troubleshoot because components may be degraded but still
operating, rather than fail completely.
To avoid such problems, touch an unpainted, grounded metal surface
before handling any such components and occasionally as you build,
especially after moving about.
For maximum protection, we recommend you take the following antistatic
precautions (listed in order of importance):
1. Leave ESD-sensitive parts in their antistatic packaging until you
install them. The packaging may be a special bag, other container
or the leads may be inserted in conductive foam (Figure 2). Parts
which are especially ESD-sensitive are identified in the parts list.
2. Wear a conductive wrist strap with a series 1 megohm resistor.
DO NOT ground yourself directly as this poses a serious
shock hazard.
3. Make sure your soldering iron has a grounded tip.
4. Use an antistatic mat on your work bench.
Figure 2. A common antistatic packaging is conductive foam which
keeps all of the terminals of a device at the same potential.
Unpacking and Inventory
We strongly recommend that you do an inventory of the parts before
beginning to assemble the kit. Even if you don’t count all the parts, an
inventory is helpful to familiarize yourself with them. A complete parts list
is included in the next section.
Identifying Parts
The parts list contains illustrations of the parts to help you identify them.
Identifying marks on the individual parts are shown in the text in
parenthesis. For example, “Transistor Q4 (PN2222)…” indicates a
transistor, Q4, which may be located in the parts list that has the characters
shown in parenthesis printed on it. Sometimes these letters are not
obvious. For example, they may be printed in light gray on a black body.
Also, there may be other marks on the device in addition to the letters
listed.
Identifying Resistors
Resistors are identified by their power capacity and their resistance value.
The power rating in watts determines the physical size of a resistor. The
most common resistors are 1/4 watt. Higher wattage resistors are
proportionately larger. The resistance value and wattage of each resistor is
shown in the Parts Lists and in the individual steps of the assembly
procedures. The silk-screened outlines on the PCBs indicate the relative
physical size of the resistors as well.
Most resistors use a color code. The color bands are listed in the text along
with the values of each resistor. For example, “R4, 100k (brn-blk-yel)…”
indicates a 100k ohm resistor and the colors to look for are brown, black
and yellow, starting with the band nearest the end of the resistor.
Some resistors use numbers instead of color bands. For example, an 820
ohm resistor might be stamped with the digits 821 instead of having gray,
red and brown color bands. Some larger resistors have their value in ohms
stamped on the body using numbers. For, example the 820 ohm resistor
would be stamped with 820 instead of 821 as described above. Normally,
when the value is shown in ohms it will be followed with the word “ohms”
or the Greek letter omega: Ω
- 4 -
Reading Resistor Color Codes
It is very helpful if you learn to read the color codes. A color-code chart
showing how to read the four-color bands on resistors with a 5% or 10%
tolerance is shown in Figure 3. 1% resistors are similar except that they
use a fifth band to provide a way of showing another significant digit. For
example, a 1,500 ohm (1.5 k-ohm) 5% resistor has the color bands brown,
green and red signifying one, five and two zeros. A 1,500 ohm (1.5 k-ohm)
1% tolerance resistor has the color bands brown, green, black and brown
signifying one, five, zero, and one zero.
The optional band shown in Figure 3 indicates other performance
specifications for the resistor. When used, it is separated from the other
color bands by a wider space.
i
If in doubt of a resistor’s value, use a DMM. It may be difficult
to see the colors on some resistors, particularly 1% tolerance resistors with
a dark blue body. Do not be concerned with minor deviations of your
DMM reading from the expected value. Typical errors in most DMMs and
the tolerances of the resistors normally produce readings that are slightly
different from the value indicated by the color bands
.
Identifying Molded Inductors
Small molded inductors have color bands that use the same numeric values
as resistors but they start near the center of the inductor and work toward
the end. These colors are listed in the text after the value of the inductor,
for example: 27H (red-vio-blk). The red stripe would be near the center
of the inductor and the black stripe would be closer to the end. On very
small chokes, the first color will be only slightly farther from one end than
the last color. There may be a variety of other stripes on inductors as well,
indicating their tolerance, conformance to certain specifications and other
data.

Identifying Capacitors
Capacitors are identified by their value and the spacing of their leads.
Small-value fixed capacitors usually are marked with one, two or three
digits and no decimal point. The significant digits are shown in parenthesis
in the text. For example: “C2, .01 (103)”.
If one or two digits are used, that is always the value in picofarads (pF). If
there are three digits, the third digit is the multiplier. For example, a
capacitor marked “151” would be 150 pF (15 multiplied by 10
1
).
Similarly, “330” is 33 pF and “102” is 1000 pF (or .001 F). You may
think of the multiplier value as the number of zeros you need to add on to
the end of the value.
- 5 -
Note: In rare cases, a capacitor manufacturer may use “0” as a
decimal placeholder. For example, “820” might mean 820 pF rather
than 82 pF. Such exceptions are usually covered in the parts list. If
possible, measure the values of all capacitors below .001 F. Most DMMs
include capacitance measurement capability.
Fixed capacitors with values of 1000 pF or higher generally use a decimal
point in the value, such as .001 or .002. This is the value in microfarads
(F). Capacitors also may have a suffix after the value, such as “.001J”.
The lead spacing is noted in the Parts Lists for most capacitors. If two
different types of capacitors have the same value, the lead spacing will
indicate which one to use. When the lead spacing is important, both the
value and the lead spacing is shown in the assembly procedure. For
example, “LS 0.1” means that the Lead Spacing is 0.1 in.
Hard-to-Identify Capacitor Values
2.2 pF: These are “disc ceramic” capacitors with round, pillow-shaped
bodies about 1/8” (3 mm) in diameter and a black mark on the top. The
capacitor should be labeled “2.2” but the marking sometimes requires a
magnifying glass to see clearly.
150 pF: These capacitors are marked “151” on one side, but the other side
may be marked #21ASD. The “#21” may look like “821”.
Assembly Process
There are seven steps in the transverter assembly process:
1. Front panel PCB assembly.
2. RF PCB assembly, part I: Parts common to all models.
3. RF PCB assembly, part II: Band-specific parts.
4. RF PCB assembly, part III: Installing the RF power module.
5. Final assembly.
6. Interconnect cabling.
7. Test and alignment.
Follow the assembly process in the order given. Each part builds on what
has been completed before it. For example, the front panel assembly
procedure contains details about installing certain parts that are not
repeated when similar parts are installed later.
Forming Component Leads
Sometimes the space provided for a component on the PCB is larger than
the distance between the leads on the part itself. In such cases, you’ll need
to carefully bend the leads out and then down to fit the given space.
Always use long-nose pliers to accomplish this task, and bend the leads –
don’t tug on them. This is especially important with capacitor leads, which
are fragile.
Step-By-Step Procedures
Perform the assembly steps in each procedure in the order given, and
do not skip any steps. Otherwise you may find that you’ve installed
one component that hinders the installation of another. When groups
of components are installed, they are listed in a logical order as you work
around the PCB to reduce the time needed to find where each part goes.
Each step in the assembly procedures has a check box.
Some steps have more than one task. For example, you may be installing a
number of components listed. When a step has a number of tasks, each
task is indented with space for a check mark:
Check off each task as you complete it.

Soldering, Desoldering and Plated-Through Holes
CAUTION: Solder contains lead, and its residue can be toxic. Always
wash your hands after handling solder.
The printed circuit boards have circuitry on both sides (“double sided”).
PCBs of this type require plated-through holes to complete the electrical
connections between the two sides.
When you solder components on these PCBs the solder fills the plated
holes making excellent contact. This means that you do not need to leave a
large “fillet” or buildup of solder on top of the pads themselves. A small
amount of solder will do for all connections.
Unfortunately, removing components from double-sided PCBs can be
difficult. To remove a multi-pin component you’ll need to get all of the
solder out of every hole to free the leads. You will need to use solder wick
or a vacuum desoldering tool (see Techniques below).
The best strategy for avoiding desoldering is to place all components
properly the first time. Double-check values, component placement and
orientation. Take care to avoid ESD damage to components.
Techniques to Avoid Damaging the PCB when Desoldering
Don’t pull a lead or pin out of a hole unless the solder has been
removed completely, or you are applying sufficient heat melt the
solder. Otherwise you can pull the entire plating out of the hole.
Limit soldering iron contact to a few seconds at a time.
Use small-size solder wick, about 0.1” (2.5 mm) wide. Use wick
on both the top and bottom solder pads when possible. This helps
get all of the solder out of the hole.
Buy and learn to use a large hand-operated vacuum desoldering
tool such as the Soldapullt® model DS017LS. Small solder
suckers are not effective.
When removing ICs and connectors, clip all of the pins at the body
first, then remove each pin one at a time, working slowly. You
may damage pads and traces by trying to remove a component
intact, possibly leaving a PCB very difficult to repair.
Invest in a PCB vise with a heavy base if possible. This makes
removing parts easier because it frees up both hands.
If in doubt about a particular repair, ask for advice from Elecraft
or someone with PCB repair experience. Our e-mail reflector is an
excellent source of help.
