    January 26 2026 #288 - Winter Field Day Debrief + Vertical Antennas and Ground Planes | W3GMS Workbench

    Harvey (KC3NZT) hosts the W3GMS Monday Night Workbench with a Winter Field Day wrap-up and a solid technical discussion focused on vertical HF antennas and “ground plane kits” for antennas like the Antron 99 and IMAX 2000. The group digs into what a ground plane is really doing (and what happens when the antenna “finds” one through your coax or tower), shares real-world results with and without radials, and connects it to practical RF-in-the-shack symptoms like USB glitches and RFI. There’s also troubleshooting from Winter Field Day—including a radio that kept rebooting (cold + battery/power sag), dipole layout considerations (flat vs inverted-V for multi-station setups), and how to track down suspected power-line noise.

    December 29 2025 #284 - Band Plans and Real World Decisions | W3GMS Workbench

    In this episode of the W3GMS Workbench, Ron, WA3VEE, pinch-hits as host on the W3GMS 146.985 MHz repeater, guiding an in-depth technical discussion packed with practical experience and hard-earned wisdom from seasoned amateur radio operators. The centerpiece of the evening is a deep-dive comparison of modern HF transceivers, sparked by a listener question weighing the ICOM IC-7300 against the Yaesu FT-DX10. The group explores real-world receiver performance, Sherwood Engineering rankings, spectrum scopes, hybrid vs full SDR architectures, transmit audio quality, ergonomics, and why raw specifications rarely tell the whole story. Operators share hands-on experience, contesting vs ragchew priorities, and why actually operating the radio matters more than datasheets. The discussion then shifts to amateur radio band plans, focusing on the often-overlooked ultra-high-frequency allocations above 10 GHz. Participants explain why these bands exist, how they’re used for experimentation, microwave links, satellites, EME, and high-speed data—and why the FCC allows broad operating privileges there. Later, the Workbench tackles a practical real-world communications problem: replacing FRS radios for church operations. The group compares DMR, MURS, GMRS, and commercial Part 90 systems, covering licensing, security, cost, antennas, and vendor options—offering clear guidance for organizations needing reliable, non-ham communications. As always, the episode blends technical insight, real operating experience, and friendly collaboration, making it a standout example of what the W3GMS Workbench does best: helping operators make smart decisions with confidence.   📡 Mondays at 8:00 PM on the W3GMS Parksburg Repeater – 146.985 MHz 🎙️ Technical Q&A, real stations, real answers 🛠️ Newcomers welcome — questions encouraged

    December 15 2025 #282 - Solar Numbers, Signal Quality, and Real-World Operating Choices | W3GMS Workbench

    This episode of the W3GMS 985 Workbench blends technical troubleshooting with on-air operating strategy, focusing on two topics every ham eventually wrestles with: signal quality and solar conditions. Hosted by W3MOW, the discussion moves from microphone levels and deviation control into a deeper look at how solar data actually affects HF operation. The group breaks down practical use of propagation indicators including K-index, A-index, sunspot numbers, MUF, and real-time band condition tools. Operators share how they interpret solar data—or deliberately ignore it—choosing instead to tune the bands, call CQ, and let experience drive decisions. The conversation highlights why charts don’t tell the whole story and how “poor conditions” often just mean fewer people calling. Additional discussion covers audio setup and mic gain control, repeater etiquette, equipment setup realities, and why longer CQs matter in the era of band scopes and waterfalls. Real-world experience takes precedence over theory, reinforcing the Workbench’s hands-on, practical approach to amateur radio. If you’ve ever wondered how much stock to put in propagation numbers—or why calling CQ still works when charts say it shouldn’t—this episode delivers grounded insight from operators who’ve tested it on the air. Recorded live on the W3GMS 146.985 MHz repeater Weekly Workbench – Mondays at 8 PM Eastern Topics include: solar indices, MUF, HF propagation, mic audio setup, repeater operation, and practical band selection

    December 8 2028 #281 - Antenna Matching, Solar Conditions, and Practical HF Decisions | W3GMS Workbench

    This episode of the W3GMS 985 Workbench centers on two core skills every HF operator eventually has to master: antenna matching and understanding propagation. Hosted by KC3NZT, the group works through real-world antenna questions and demystifies solar data that directly affects on-the-air results. The first half of the discussion focuses on non-resonant vertical antennas, including the Eagle One design, and when un-uns, choke baluns, radials, and remote tuners actually matter. Operators break down impedance behavior by band, explain why some verticals demand transformers while others don’t, and highlight practical strategies to reduce feedline loss and RF problems in multi-band setups. The second major topic dives into Solar Flux Index (SFI), sunspot cycles, and space weather. The group explains what SFI actually measures, how it impacts HF propagation, why geomagnetic indices matter, and where to find reliable solar data. Recommended resources and real operating experiences help connect abstract numbers to real band openings and closures. As always, the Workbench blends theory with hands-on experience, offering clear explanations without marketing hype. If you’ve ever wondered why an antenna “should work” but doesn’t—or why the bands suddenly light up or die—this episode delivers answers grounded in practice. Recorded live on the W3GMS 146.985 MHz repeater Weekly Workbench – Mondays at 8 PM Eastern Topics include: vertical antennas, baluns and un-uns, radials, feedline loss, SFI, space weather, and HF propagation
