While the Mercator map aids navigation, it complicates radio signal analysis. Adjusting map visuals enhances understanding and facilitates the use of Beverage antennas, improving data readability and quick information absorption for users managing multiple antennas.
How we built a custom device to switch between our four Beverage antennas for longwave and lower shortwave work.
How we spec’d and simulated a low-frequency Beverage preamp covering 25 kHz to 3.5 MHz — covering everything from VLF to the 80m band with what was already on the shelf.
We stripped a neighbor’s dead AC unit and buried the condenser coil next to our lab. Here’s why a 7.5 m² copper plate beats a standard ground rod by 200:1 in decomposed granite, and how we achieve this massive ground with almost no budget and some elbow grease.
Most RF data is generated above HF. We work below it, in the long-wave bands where the data is sparse, the physics is weird, and the discovery potential is high. Here’s what we plan to do with the data.
See our cost-effective strategy for building an antenna setup. From neighbor’s discarded HughesNet dishes to a 67-foot tower scored on Facebook Marketplace, this is how we build an antenna arsenal without the red tape. The approach fosters rapid experimentation in RF research without waiting for ideal conditions or funding.
As far as we know, no one else operates an electrically steerable antenna on the 630m band. Here’s how we’re building ours and and what the data could reveal about soil, atmosphere, and seismic activity.
Our implementation of Beverage antennas for long-wave, low-frequency research. These antennas are effective for weak signal analysis but require specific site conditions and technical considerations. The project utilizes a 20-acre property. We discuss how we facilitate optimal placement and signal reception, paving the way for future research collaborations.
An overview of various antennas at our site: The Giga Loop, covering 15 acres, offers global reception. A fan dipole hangs about 75 feel over a canyon. Vertical antennas serve multiple bands, highlighting practical uses and improvisation with available materials.
This post details a WSPR beacon project, including a homebrew oscillator and microcontroller, achieving notable long-distance transmissions. Despite challenges like low power and drift, we’ve successfully transmitted signals on multiple bands with innovative antenna designs.
