Tune in now to learn everything you need to know about installing a radio tower! In amateur radio, QRP operation refers to transmitting at reduced power while attempting to maximize one's effective range. QRP operation is a specialized pursuit within the hobby that was first popularized in the early 1920s. QRP operators generally limit their transmitted RF output power to 5 watts or less for CW operation and 10 watts or less for SSB operation.[1] Reliable two-way communication at such low power levels can be challenging due to changing radio propagation and the difficulty of receiving the relatively weak transmitted signals. QRP enthusiasts may employ optimized antenna systems, enhanced operating skills, and a variety of special modes, in order to maximize their ability to make and maintain radio contact. Since the late 1960s, commercial transceivers specially designed for QRP operation have evolved from vacuum tube to solid state technology. A number of organizations dedicated to QRP operation exist, and aficionados participate in various contests designed to test their skill in making long-distance contacts at low power levels. Elecraft KX2 with an ATU eliminates tedious length adjustments. Just select a band, tap the antenna tune switch, and go for it. The AX1 is resonant on 20 meters in one switch position, while the other is designed for efficient 17 and 15 meter matching using an ATU. Whether you use the AX1 as a ‘stealth’ field antenna, for pedestrian mobile, or as a versatile backup, it’ll be ready when you are. Resonant Frequencies 20 m (~14 MHz) and 17/15 m (~19 MHz). Resonant frequencies may vary +/- 300 kHz or more due to changes in terrain, body capacitance, and antenna height. Supplied Radial Wire 13 feet (4.0 m) long. Wire has pre-installed lug for attachment to the transceiver’s ground screw. Max. Power 30 Watts. If RFI symptoms are observed, reduce power or move antenna farther from the transceiver. Construction Corrosion-resistant whip and hardware; Lexan outer tube; high-Q inductors wound with 20 AWG, high-temp enamel wire. Dimensions Whip: 6” (15 cm) collapsed, 45” (115 cm) extended. Base: 6” (15 cm) long x 0.75” (19 mm) diameter. Weight Antenna: 3.2 oz. (90 g); supplied radial wire: 0.6 oz. (17 g).
