Posted by: Eric / WA6HHQ Posted On: 09/05/03 Subject: New Elecraft Product: KX1 Ultra-portable HF QRP Transceiver Message Posted: The Elecraft KX1 is a very compact, multi-band CW transceiver optimized for backpacking and travel use. With internal battery, internal automatic antenna tuner, plug-in keyer paddle, and log-book lamp, it offers a high level of integration. 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). Unlike most transceivers, the KX1’s controls are located on the top of the cabinet, and the keyer paddle attaches at the front. This “trail-friendly” format is ideal for hand-held or lap-top operation, e.g. when sitting on the ground, using a camp chair, reclining, or even standing. The KX1 is also at home on a table, providing an optimal viewing angle without a tilt stand. The unique plug-in keyer paddle is angled at 45 degrees for ease of use and is both physically and electrically reversible for right- or left-handed operators. The transceiver covers the full 40 and 20 meter bands, and optionally 30 meters. The VFO uses a DDS (direct digital synthesis) IC, so it can also tune nearby SWL band segments. A variable-bandwidth crystal filter permits reception of SSB and AM as well as CW. This facilitates cross-mode contacts and reception of HF AM broadcast stations. The KX1’s internal six-cell battery pack can be changed in seconds with the removal of two thumb screws. The battery provides 1 to 2 watts power output. An external 12 V supply increases output to about 4 watts. Low receive-mode current drain (34 mA typ.) results in internal battery life of 20 hours or more during casual operation. The KX1 uses a highly-efficient 3-digit LED display that adds just 1 to 2 mA to total current drain in moderate lighting conditions. The operator can adjust both the display brightness and off-timeout (after last keypress). Operation without the display is possible if the CW feedback feature is turned on. This provides audible readout of the VFO frequency and other information. Additional features include frequency memories, three VFO tuning rates, RIT, and S-meter display. The built-in keyer offers Iambic modes A and B and two message buffers. In an emergency, two front panel switches can be used as a keyer paddle or manual key. The KX1 is suitable for first-time builders. The basic unit consists of a single printed circuit board, with no surface mount components to install (the three surface mount parts used are pre-installed). The KX1 kit sells for $279. First shipments will commence at at the Pacificon convention, Oct. 17-19th, and the week following.
