VHF UHF Operating Modes and Resources
Find resources for VHF and UHF operating, including weak signal, DX, contesting, repeaters, and propagation.
VHF and UHF bands offer hams exciting opportunities for local QSOs, DX, and experimental work beyond the typical HF experience. Operators use these frequencies for everything from casual chats on repeaters to challenging weak-signal contacts via meteor scatter, aurora, or even Earth-Moon-Earth (EME) paths. These bands are also popular for contests, where stations often deploy large antenna arrays and specialized transceivers to maximize their range and score.
This category provides resources for VHF and UHF operators, including propagation forecasts and activity reports for regions like EI and the USA. Hams can find information on band plans, beacon lists, and tools for RF path planning. There are also guides for weak signal operation, EME basics, and software for antenna design and contest logging. Experimenters will find projects and tips for pushing the limits on bands up to 10 GHz, with insights from pioneers like K3PGP.

The 8m ISM band, a unique frequency range between 10m and 6m, holds potential for amateur radio enthusiasts, yet it remains largely unallocated. This spectrum offers fertile ground for research and self-training. The author's experience with low-power transmissions and WSPR testing highlights the band's capabilities and the need for a narrow, speech-free amateur allocation to encourage experimentation. Discover the world of 8m ISM radio exploration and its future possibilities. -
This PDF presentation explores using aircraft reflections for VHF communication. It explores the characteristics of reflected signals, including how they cause fading and vary in frequency due to aircraft movement. The feasibility of using such signals for communication is then examined. The presentation highlights challenges like requiring very narrow filters and strong frequency stability. It explores Slow-Feld, a slow version of Hellschreiber, as a potential modulation mode due to its tolerance for weak signals and frequency variations. While successful communication via aircraft reflections has been achieved, the data rate was slow and intermittent. The potential for communication over long distances, especially with busy air traffic, is discussed. -

When new to the 2-meter FM transceiver, securing a quiet frequency for chatter seems straightforward, but it's essential to navigate FCC rules and band plans effectively. Even though frequency allocations are consistent above 50 MHz for Technician licenses, adherence to specific segments within the 2m band—ranging from 144 MHz to 148 MHz—is crucial. This includes respecting designations for different modes like CW, SSB, and FM to prevent interference, particularly with satellites and exotic modes like EME. Understanding and following the structured band plans not only ensures legal compliance but also optimizes frequency use and minimizes disruptions in the amateur radio community.
