Radio Waves: Stories Making Waves in the World of Radio
Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers. To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!
This issue concerns High-Frequency Trading (HFT) transmissions, and three prospective stations seeking entry into the International Broadcast service.
Several stations licensed in the Experimental Radio Service (ERS) transmit data for automated trading to foreign exchanges in the shortwave or high-frequency (HF, 3-30 MHz) spectrum.
High-Frequency Trading (HFT) is a form of automated trading that employs low-latency, high-speed telecommunications to minimize response times. The term is not related to the shortwave or HF spectrum, but this article concerns transmission of HFT messages on HF frequencies.
HF signals can traverse great distances by refraction from ionized layers of the atmosphere, a phenomenon known as ionospheric propagation. Several ERS HFT stations have operated in the HF bands for years out of the public view. Bob Van Valzah blogged extensively about these stations starting in 2018.
These ERS stations’ licenses are public records, but the licensees typically ask the FCC to withhold access to station details and experimental plans. The Commission’s routine acceptance of these confidentiality requests makes public oversight difficult. [Continue reading at Experimental Radio…]
Radio Bulgaria back on shortwave
Many thanks to SWLing Post contributor, Richard Langley, who writes:
As I reported to Glenn Hauser’s group today, Bulgarian National Radio’s Radio Bulgaria is back on shortwave.
Their weekday roughly 22-minute podcast in English, called “Bulgaria Today,” is being aired by ShortwaveService from Kall, Germany, on 3985 kHz from 18:30 until about 18:52 UTC.
Today (30 January), the podcast dated Thursday, 27 January, was broadcast. The program consisted of news, COVID-19 information, weather, travel, and the “Music Slot.” Reception using the U. Twente SDR receiver was fairly good.
There is also a German broadcast before the English one beginning at 18:00 UTC. The ShortwaveService tuning signal is used to fill out the half-hour slot in each case.
All the best

NEW YORK — Howard Hesseman, who played the radio disc jockey Johnny Fever on the sitcom “WKRP in Cincinnati” and the actor-turned-history teacher Charlie Moore on “Head of the Class,” has died. He was 81.
Hesseman died Saturday in Los Angeles due to complications from colon surgery, his manager Robbie Kass said Sunday.
Hesseman, who had himself been a radio DJ in the ’60s, earned two Emmy nominations for playing Johnny Fever on CBS’ “WKRP in Cincinnati,” which ran for four seasons from 1978-1982. The role made Hesseman a counterculture icon at a time when few hippie characters made it onto network television. [Continue reading…]
