DX Engineering is excited to announce another valuable addition to its lineup of more than 175 amateur radio providers from around the world: 4O3A. You can find 30,000-plus ham radio products from these leading manufacturers—including 4O3A and DX Engineering branded equipment—at DXEngineering.com.
About 4O3A
The 4O3A call sign belongs to accomplished contester Ranko Boca, who earned his first license in 1980 and went on to participate in multiple World Radiosport Team Championships (WRTC). The 4O3A superstation is located on the Lustica peninsula at the entrance of the Bay of Kotor in southwestern Montenegro. The station—“Ham Radio Paradise,” as it’s called on the 4O3A website—offers a spectacular view from its position on Obosnik Hill, the highest point in the peninsula.
As a company, the innovators and world-class contesters at 4O3A design and manufacture high-quality products that help hams operate more efficiently and push contest scores higher. DX Engineering carries several products from 4O3A’s flagship line of Genius Solutions products that work with FlexRadio transceivers and other modern HF rigs: the Power Genius XL Amplifier, Tuner Genius XL Antenna Tuners, and Antenna Genius 8X2 Plus Antenna Switch.
Also look out for 4O3A band pass filters available soon from DX Engineering.
A Sound Choice for Better Audio
Understanding the competitive edge that crisp and clear audio delivers in a contesting environment, the 4O3A team developed the NC-1 Noise-Canceling Bluetooth Boom Mic Headset. This multipurpose combo features light and comfortable over-the-ear headphones that provide excellent ambient noise canceling and crystal-clear sound—perfect for long hours of contesting as well as enjoyment of music, podcasts, and more.
The headset includes a top-of-the-line noise-canceling system with up to 25 dB of noise reduction; 40mm size neodymium drivers that allow you to hear the slightest details during a contest or while listening to a Beethoven sonata; Bluetooth 5.0 for Android and Apple mobile devices, laptops, tablets, PC, and interfaced radios; and up to 30 hours of worry-free operation on a single charge of the provided 750mA rechargeable Li-Ion battery.
The plug-in omnidirectional condenser boom mic set provides superior vocal clarity with a wide, flat frequency response. The MC-1 boom mic set works for all transceivers (with optional adapters) and plugs into laptops, tablets, and PCs. It comes with universal 3.5mm mic and headphone cables (detachable from the NC-1 Headphones for use without the boom mic) and includes soft case, 3.5mm to 6.35mm adapter, and two boom mic windscreens. Headphones and a boom mic also available separately.
