Elecraft KX3 Amateur Radio Transceiver - electronics - by owner - sale - craigslist (2024)

Current MSRP of all components is over $2000 before tax and shipping.

Photos are all of the actual items for sale, taken June 7, 2024. The Elecraft PX3 panadapter shown in the photos was sold separately.

I have ceased operating portable and do not have a workable location for indoor operation, so this equipment is no longer of use to me any more. Everything is in top working order - non-smoking operator/home.

Pricing is for local pickup. Shipping to neighbor islands or mainland can be arranged for actual shipping cost.

Transceiver has the following options factory installed:
-KXFL3 Roofing Dual Bandwidth Filter for SSB/CW/DATA
-KXAT3 Internal, Wide-Range 20-W Automatic Antenna Tuner

Included accessories:
-MH3 Hand Microphone with UP/DN Controls
-KXUSB - USB RS232 to 3.5mm cable
-2 power plugs/cables (5.5mm OD / 2.1mm ID) and PowerPole-terminated leads to 12V batteries with F2 terminals.

--ACC2 Module: 2.5mm stereo right-angle to KEY OUT and PTT IN (or Transmit Inhibit, or AuxBus) molded module.

WindCamp optional side panels, canvas tote bag, and acrylic cover plate are included. A removable adapter providing an extra 3.5mm CW/Morse key jack is installed on the radio's keyer port.

Also included is a 3-piece wooden desk stand for the KX3 and PX3 produced by the North Georgia QRP Club (www.nogaqrp.org).

Instruction/operating manuals are included.
___________

The KX3's unique form-factor allows you to operate from anywhere. Fold out the rear tilt-feet for use on a desktop or picnic table. For extreme portability, you can add the internal wide-range ATU, 8-AA cell battery pack with NiMH charger, and adjustable KXPD3 keyer paddle. With a whip antenna, you can even operate hand-held.

In receive mode, current drain can be as low as 150 mA - about one-half to one-third that of competing all-band portables. Transmit efficiency is also excellent, further improving battery life.

Full-Featured, Yet Easy to Use

The KX3 features a large front panel with all controls optimized for convenient use. You won't have to dig through menus to set the power level, adjust the keyer speed, or change filter settings. And the KX3 has the same full-size display as the Elecraft K3S, so all operating information is available at a glance.

The KX3's tutorial-style manual explains how and why controls are used, so new Hams will be experts in no time. Of course, you'll also have Elecraft's legendary customer support and free firmware upgrades via the internet.
