Assembly Manual

Introduction

This manual covers assembly of the Elecraft T1 automatic antenna tuner. Operating instructions,
troubleshooting procedures, schematic diagram and customer service information can be found in your T1
Owner’s Manual.

Tools Required

You will need the following tools to build this kit:

 Fine-tip temperature-controlled ESD-safe soldering station with 700 to 800F tip (370-430C).

Recommend a spade tip no greater than 0.05” (1.3 mm) wide.

 High wattage (approx. 100 watt) soldering gun to solder the BNC connectors. Use this iron only

where directed in the procedure. Use the temperature-controlled station for all other soldering.

 IC-grade, small-diameter (.031”) solder (Kester #44 or equivalent). Small diameter solder is

important to avoid filling adjacent solder pads and creating solder bridges.

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.

 Small, #2 Phillips screwdriver.
 Needle-nose pliers.
 Small wrench or driver for 6-32 nut.
 Small-point diagonal cutters. Flush-cutting type required (Xcelite MS54-5J or equivalent).
 Digital Multimeter (DMM) with voltage, resistance and diode-checking functions. A DMM with

capacitance measurement capability is desirable, but not required.

 Magnifying visor or magnifying glass with a hands-free stand.
 Desoldering tools and supplies are invaluable. Narrow solder wick or a good vacuum desoldering

tool such as the Soldapullt® model DS017LS are recommended.

 Small, #2 (1.4 mm wide) blade screwdriver may be required.
