A 500-watt mobile antenna project details the conversion of an old 10m hamstick into a highly efficient, multiband "bugstick" for HF operation. The core modification involves replacing the original coil with 25 turns of 6 turns-per-inch, 1.5-inch diameter coil stock, fabricated from #14 wire. This design, intended for a 3-magnet mount on a vehicle cab, achieves resonance on multiple bands by shorting out specific turns on the coil, similar to a **bugcatcher** antenna. Measurements taken with an MFJ-259 analyzer on a GMC pickup show 0 turns shorted for 20 meters (14.2 MHz), 10 turns for 17 meters, 16 turns for 15 meters, 19 turns for 12 meters, and 23 turns for 10 meters. The construction emphasizes using UV-resistant tie-wraps and #14 solid wire with crimp lugs for robust RF connections, bypassing the fiberglass rod for current flow. A bonus section details a 40-meter version, utilizing 48 turns of 8 TPI, 2-inch diameter coil stock.

The **United States Islands (USI) Awards Program** is an amateur radio operating activity centered on activating and chasing islands located within the fifty states of the United States, its territories, and protectorates. These islands encompass coastal shores, lakes, rivers, ponds, and streams, offering a diverse range of operating environments. The program provides numerous achievement awards for both island activators and island chasers, encouraging portable operations and mini-DXpeditions. Participants engage in year-round activities, including the **One-Day-Getaway (1DG)**, a casual portable operation held on the second Saturday of May, and the U.S. Islands QSO Party (IQP), a 15-hour contest occurring on the last full weekend of August. USI encourages hams to discover and operate from islands in their local areas, providing an alternative to traditional Field Day operations for outdoor radio enjoyment. The program supports various operating styles, including portable, walk-on, paddle-to, motor-to, mobile, and drive-on activations. Recent activities include AC1RH activating MA064R Eagle Island daily, aiming for over 100 activations using 600 watts, and KD9ZAB and KD5YZY qualifying MO021R Tower Rock, which is also a POTA US-10147 location. The USI program maintains a clear distinction from the Islands On The Air (IOTA) awards program.

The information in this article has come from many amateur sources, the most notable was from WA6TEY (sk 1985) Ray Frost, who was a pioneer of VHF Quad designs and one of the best Southern California Transmitter Hunters. Ray built hundreds two meter quads in single and paired configurations as well as his famous mobile radio direction finding quad.

Examines the Icom IC-2100H 2-meter mobile transceiver, detailing its operational characteristics and user experience. The review highlights the clear, easy-to-read display with internal labels, the button-filled microphone's functionality, and the rig's physical construction, including its weighty heat-sink and lack of a cooling fan. It also discusses memory programming, the unique amber-to-green backlight color options, and the radio's performance against _intermodulation_ in urban environments, noting it performs "pretty darn good" compared to other rigs. The analysis delves into a significant low-voltage cutoff problem, where the microphone ceases to function below approximately **12.6 VDC**, rendering the radio receive-only or causing it to stick in transmit. The author describes testing the voltage cutoff, observing it fluctuate from _12.38 VDC_ to 12.69 VDC. An update from Icom involved a "factory update" to the CPU's control code, which is strongly recommended for early-serial number units to prevent operational failure in low-power emergency scenarios.
