Sporadic E Propagation

Sporadic E propagation is a result of highly ionized patches or “clouds” that occasionally form in the E region of the ionosphere at altitudes between approximately 80 and 150 kilometres.

Communication distances of 800–2000 km can occur using a single Es cloud. This variability in distance depends on a number of factors, including cloud height and density. MUF also varies widely, but most commonly falls in the 25 – 150 MHz range which includes the amateur radio 2-meter, 6-meter, and even the 10-meter bands. Strong events have allowed propagation at frequencies as high as 250 MHz.

One Megawatt of Peak AM Power - Saving the Voice of America Delano Relay DL-8

In 2007, the Voice of America ceased operations at the Delano Relay site in Central California.  The site is destined to be bulldozed along with several relics of Collins Radio Company's Broadcast Communications Division.  The Collins Collectors Association, with assistance from the Antique Wireless Association, hatched a plan to retrieve one of the Collins 821A-1 250 KW Shortwave Transmitters from the site and place it on display for all to see.  This presentation gives some history of VoA and the Delano site and follows the disassembly and relocation of Delano Relay DL-8.

ARKnet Wireless Emergency Intranet - QSO Today Virtual Ham Expo 2020

ARKnet is the first step toward building a Wireless Emergency Intranet for the City of Cupertino that will support our emergency responders with a high-speed data network. This multi-site network uses a 5.8GHz ISM backbone and includes off-grid solar sites throughout the city. This forum will provide an overview of the system including design considerations, initial deployment of the primary sector and client sites, and operational analysis of the system functionality.

Salt Water Effect Fact Or Fiction for Ham Radio Operators

Greg N4KGL has taken advantage of the so-called saltwater effect for vertical antennas while operating QRP portable right on the shoreline around his home area in Northwest Florida. His presentation will discuss an attempt to quantify the saltwater effect using the Weak Signal Propagation Reporter WSPR beacons. The initial data shows the advantage of operating on the saltwater shore. Greg uses a Microsoft Access database to provide data analysis. Greg is looking for collaborators to continue his experiments and make them more rigorous. This talk was prepared for the QSO Today Virtual Ham Expo and played on August 9th, 2020.

Everything you need to know about Lithium Batteries- Marcel Stieber AI6MS

Batteries are a necessity for almost all portable radio operations. With the advent of modern battery chemistries, the choices available to the radio amateur are plentiful. This presentation will focus on the three common battery types: Lead-Acid (SLA/AGM), Lithium (Lion/Lipo), and Lithium Iron Phosphate (LFP/LiFePO4). We'll discuss the pros and cons of each chemistry, common uses and misuses, and everyday application tips for your latest amateur radio project.

AT&T Archives: Similiarities of Wave Behavior (Bonus Edition)

On an elementary conceptual level, this film reflects the multifaceted scientific hyperthinking that was typical of a Bell Labs approach. Host Dr. J.N. Shive's presence as a lecturer is excellent - it's understandable by a layperson even when he branches into equations, because he uses copious amounts of real-world examples to bolster the material.

FT5XO Kerguelen DXpedition

Located halfway between Africa and Australia, and just about as far away from North America as possible, this icy, windswept island has always held a top spot on the DX world's most wanted lists. But just what kind of DXer does it take to leave home for six weeks and travel to such a faraway place?
