Directional antennas do have their strengths such as power over distance but sometimes you may need to use a good omnidirectional antenna to produce 360 degrees of coverage over a smaller area.
So this video is a different take on the traditional biquad antenna and I will show you how to make an omnidirectional biquad for 2.4 GHz.
Tad Cook, K7RA, Seattle, reports: We saw one day during the February 25 – March 3 reporting week — Monday, March 1 — with no sunspots, so the average daily sunspot number declined slightly from 19.6 to 18.9. Two new sunspot groups (2806 and 2807) appeared on Tuesday, March 2. Average daily solar flux increased […] Read more

Icom will be releasing new firmware for our IC-705, IC-7300 and IC-9700 transceivers. The updates are planned to improve the user experience and incorporate communication modes such as FT8. The firmware is due to be released around the end of January 2021 starting with the IC-705 (Version 1.20 added 22/01/21) and followed shortly by versions for the […] Read more
US Army researchers have built a so-called “quantum sensor,” which can analyze the full RF spectrum and real-world signals, a report on Physics.org says. The quantum sensor — technically a Rydberg sensor — can sample the RF spectrum from 0 to 20 GHz and is able to detect AM and FM radio signals, as well as Bluetooth, […] Read more
RF noise is a frequent discussion topic among radio amateurs. A proliferation of electronics has cluttered and complicated the noise environment; it’s not just power lines anymore. Unless isolated from civilization, most hams experience RF interference (RFI) — sometimes without even realizing it, although spectrum scopes on modern transceivers make RF noise much more apparent. […] Read more
Amateur Radio on the International Space Station (ARISS) International Chair Frank Bauer, KA3HDO, reports that the ARISS team has been working closely with NASA and the European Space Agency (ESA) to identify what may have caused what ARISS is calling a “radio anomaly” on January 27. The net result has been an inability to use […] Read more
We take a look at one of the most recent HF transceivers to come onto the ham radio market. Could this be the new FT-101E that was one of the best sellers of the 1960s? Peter Waters G3OJV, takes a look and reports on his three weeks of using this radio. Read more
William Noble asks about the base used to hold up my MFJ-1846 Hex Beam antenna. The actual base that allows for a fold-over mast was designed by friend Mike Bergman and welded by his son Carson. It’s held to the ground by four 3-foot stakes and is exceptionally sturdy. Many thanks to Mike and son! Read more
Responding to comments and recent videos here on Youtube. Is there a big threat to amatuer radio operators fourth amendment rights? Are we opening outselve sup to “Warrantless Searched”? Well, its complicated, but I will try to walk through it. Read more
