INTRODUCTION

Your new Xiegu X5105 is an ultra-portable multi-mode HF transceiver that delivers an unusually wide range of operating features -- many normally only found on much larger base-station radios. For example, it comes with a 3.6-inch high-visibility LCD screen that displays a wide range of information covering virtually every aspect of the radio’s operation. And, even though the X5105 is physically small, its operating controls have been thoughtfully laid out with adult-sized fingers in mind!

The transmitter covers 160 through 6 Meters with power output adjustable from 0.5 to 5.0 Watts. Transmit and receive modes include USB/LSB, CW, FM, AM plus digital inputs (1.5-W carrier on AM). You also get a built-in SWR Bridge plus a highly effective Automatic Antenna Tuner (ATU) that allow you to operate almost anywhere using a wide range of portable and fixed antenna systems.

The X5105 receiver is general coverage, tuning from the AM broadcast band through 30 MHz (plus 50-54 MHz). VFO tuning is velvet-smooth with 1-Hz resolution, and DX splits are easy using the VFO A/B mode and receive incremental tuning (RIT). You’ll also notice that weak-signal reception and adjacent channel interference are well managed using a built-in Pre-Amp/Attenuator, pulse-type Noise Blanker, adjustable DNR (Digital Noise Reduction), Notch Filter, variable AGC-Rate, and adjustable-width Passband Filters. For serious CW operators, there’s a multi-mode Auto-Keyer complete with memory channels and CW-trainer. For voice modes, you get a built-in Speech Compression processor to add punch when working DX -- plus a sophisticated multi-function key-pad microphone that places many of the radio’s most advanced operating features right at your fingertips.

Also, you can say goodbye to tangled patch cables and the extra “boxes” that normally accompany QRP operation because all the accessories you’ll ever need are built right into the radio. There’s even a front-panel microphone and MOX switch for operating in “speaker-phone” mode. Best of all, with its powerful 3800-mAh on-board battery pack, you get up to 6-8 hours of energy-independent portable operation between charges (the X5105 also operates from any regulated 9-15 Volt 3-Amp dc supply).

Even though it’s loaded with features, the X5105 is still extremely compact and light, measuring 6-5/8” wide x 3-5/8” high x 1-7/8” deep, and weighing just 2.1 pounds. Positive proof that remarkable things come in small packages!
