Constructing a **2-meter** J-pole antenna from readily available copper plumbing components offers a robust and cost-effective solution for VHF operation. This design, dubbed the "Plumber's Delight," functions essentially as a half-wave dipole fed by 50-ohm coax via a **gamma match**. It incorporates a quarter-wave copper tubing support, which, when affixed to a metal mast or tower, enhances forward power in the direction of the radiating elements. The original configuration utilized a small ceramic trimmer capacitor for the gamma match, suitable for up to 10 watts. A subsequent modification replaced this with a 50 pF variable capacitor housed in a plastic enclosure, accommodating higher RF power and improving weather resistance. The antenna elements are secured using a copper "T" fitting, and an SO-239 connector mounts directly to this fitting. Performance includes gain away from the support mast, and tuning is straightforward by adjusting the gamma match capacitor for a 1:1 SWR. The total cost for materials, excluding the capacitor and coax, can be under $10. -

Unified Microsystems presents a range of amateur radio products, notably the **XT-4 MK2 CW Memory Keyer**, a battery-powered iambic keyer designed for portable operations like Field Day, POTA, SOTA, and DXpeditions. It features four non-volatile memories, each storing approximately 240 Morse characters, and operates at speeds from 8-45 WPM. The XT-4 MK2 also includes an auto power save function and paddle reverse, making it adaptable for multi-operator setups. Beyond the XT-4 MK2, the site details the **W9XT Contest Card**, a PC plug-in board offering DVK and CW interface capabilities, allowing operators to record and playback CQs and contest exchanges. Other offerings include the BevFlex-4X RX Antenna System, RAS-4 RX Antenna Switch, VK-64 Voice CW Keyer, and various USB interfaces. Additional products cover electronic development, such as the ATS-1 Terminal Shield for Arduino™ and VR-X Power Supply Voltage Regulators, demonstrating a broader scope beyond just operating accessories. The XT-4Beacon MK2 / CW IDer is also highlighted for beacon projects, capable of storing messages up to 5 minutes at 25 WPM.
