LuvMe
Thank you for an enclelext article. Currently, I’m in the process of changing my antenna configuration from a random wire to a dipole, inverted-vee or sloper. As mentioned in your article, defining your type-of-contest is important then, matching your antenna system. My contest focus is domestic and budget friendly wire antennas can compete against yagis. I’m looking forward to adding a little more gain into the KA3DRR signal from the central coast of California.

Elecraft K3
In a first for the industry, the K3’s identical main receiver and subreceiver each feature a high-dynamic-range, down-conversion analog architecture. This allows Elecraft to provide roofing filters with bandwidths as narrow as 200 Hz, while up-conversion designs have roofing filters typically 3,000 to 15,000 Hz in width. Unlike some competing down-conversion designs, the K3 also provides 6-meter coverage, as well as continuous tuning from 0.5 to 30 MHz. Each receiver has its own bus-switching mixer, narrow ham-band front-end filters, 32-bit I.F. DSP, low-noise synthesizer, and up to five crystal roofing filters.

Elecraft KX1 Ultra Portable CW Transceiver
The Elecraft KX1 is a backpacker's dream: an ultra-light, multi-band CW station with internal battery and automatic antenna tuner. But it's also the perfect rig for shorter hikes, emergency use, and just plain fun.
The enclosure measures just 1.2 x 3 x 5.3 inches (3 x 7.5 x 13 cm), and the transceiver weighs just 9 ounces (11 ounces with both the optional ATU and keyer paddle installed).

KX3
Ultra-Compact Home/Portable/Mobile Station
The revolutionary Elecraft KX3 puts the world in the palm of your hand! Despite its small size, it covers all amateur bands from 160-6 meters, operates in all modes, and has DSP-based features usually found only on larger radios.
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, or add our rugged mobile mount bracket for vehicle use. 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 K3, 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.
KXPA100 External 100-Watt Amplifier
Our high-performance KXPA100 home/mobile amplifier seamlessly integrates with the KX3 as well as other popular 5- to 10-W transceivers. It has its own internal ATU option (KXAT100) with dual antenna jacks.
