Great catch, Dan! If I ever find an XCR-30 in great shape, I think I’ll snag one. I’ve always loved their simple, all-business front panel and legendary–once benchmark–performance.

Dear Thomas,
Thank you for all good articles on the SWLing Post.
After the passing of Top 40 radio disc jockey Dan Ingram of WABC 770 AM and later WCBS 101.1 FM, the golden days of Top 40 radio in New York City, the biggest radio market in the United States has been observed in TV and articles. Since 1988, no major AM station in the New York market plays pop music.
In 1960 WABC 770 AM changed format top Top 40 with upbeat disc jockeys, taking advantage of its 50,000 Watts clear-channel undirectional transmitter with the possibility to reach distant suburbs even 100 miles away during daytime and large portions of eastern United States and Canada after sunset. Its competitors at time were Top 40 stations 1010 WINS, 570 WMCA and 1050 WMGM but with directional transmitters.

In the mid-1960s and on to the 1970s WABC had a long line of radio personalities like Dan Ingram, Harry Harrison, Ron Lundy, “Cousin Bruce” Bruce Morrow, and Chuck Leonard to name a few. Teenagers would enjoy listening to WABC with their transistor radios being popular. In the 1970s WABC was often No 1 or 2 in the New York radio ratings.
However, the Top 40 format was to become less popular in AM with FM stations starting to play hits. WMCA dropped its Top 40 format in the fall of 1970. Despite rivals from FM stations like WXLO 99X, soul station WBLS, album-oriented rock stations like WPLJ and WNEW-FM, WABC stayed on top until 1978 with the only notable AM competitor being 660 WNBC with an adult-leaning Top 40.
But when FM-station Mellow WKTU 92 changed format to disco and became Disco 92, an FM became the No 1 station in New York City putting down WABC to No 2 in December 1978. WABC started to play more disco but the audience became confused. With new management WABC started to aim for an older audience playing more adult contemporary songs. By 1981 WABC played more oldies and started to promote talk shows. In May 1982 it was announced that WABC would become a talk radio station. On May 10, the music ended on WABC and it was in radio called the day music died.

1010 WINS dropped rock and roll music in 1965 and became an all-news station. 1050 WMGM (WHN from 1962) had various music formats until 1987 when it became all-sports.
660 WNBC was the last of the major Top 40-stations to drop music. It had various pop music formats until 1988 when it became all-sports 660 WFAN since WHN/WFAN changed to that frequency. 660 WNBC introduced shock jock Don Imus and afternoon jock Howard Stern.
Many of the disc jockeys, including Dan Ingram, would join 101.1 WCBS-FM, playing oldies with the Top 40 disc jockey upbeat. The classic Top 40 era with double-digit ratings and the nighttime signal reaching hundreds of miles away was gone.
The website Musicradio 77 has a lot of resources and memorial about WABC but also WMCA: https://musicradio77.com

Thank you, Patrick, for the stroll down Memory Lane–and thanks for sharing the informative links and videos!
I truly appreciate honoring Dan Ingram as well–no doubt, there are many SWLing Post readers who remember him from WABC. He was and will always be a radio legend.

LED lights jam shipping Automatic Identification System
VERON report investigators from the Netherlands Radiocommunications Agency have discovered RF Pollution emitted by LED lights caused the loss of AIS shipping signals around 162 MHz
A Google English translation of the Radiocommunications Agency article reads:
In the mouth of the Waalhaven in the Nieuwe Maas in Rotterdam, ships from the electronic map have been missing for some time. The Port of Rotterdam Authority and skippers were completely in the dark about the cause of this.
In the busy Rotterdam port area, of which the Waalhaven is a part, it is important that you know where everyone is. A ship that automatically sends its position and data via AIS – and is therefore visible on the electronic navigation chart – not only increases safety, but also shortens the waiting times for the berths and waiting areas. And what about ships loading and unloading dangerous goods or passenger ships? These are continuously monitored. If such a ship is dropped, dangerous situations can arise.
During an investigation the inspectors of the Radiocommunications Agency quickly discovered that the frequency band for AIS signals was disturbed. And after several polls in the surroundings of the Waalhaven they came to a work of art. In an atelier near the mouth of the Waalhaven, an artist had made a work of art with the help of LED lights. All these lights appeared to be the key to the solution together with the power supply.
Because LED lights are indeed economical, but if you do not buy the right one or install them incorrectly, they cause a lot of problems. In this case, the frequencies of the AIS band were therefore disturbed. After the power of the lighting was switched off, the disruption was resolved. In retrospect, it appeared that the lighting and the power supply exceeded the interference limits. To prevent new failures, a solution is sought for the artist together with the business community.
The agency also regularly receives reports of disruptions of AIS reception from the Amsterdam port area. Here, too, we conduct an investigation. If something interesting comes out of this, you may read more about this in the next newsletter. To prevent disruptions, we regularly monitor frequency use (preventively). Especially in areas with busy shipping traffic.
Thank you for your website it gives me taste on the radio.73’s Olivier F4BXV
Many thanks, Olivier! I’ve always loved this über-compact AM/FM radios. They remind me of the small radios I used to sneak into school when I was a kid! Sounds like the SRF-M95 is a capable little receiver as well–thanks for sharing the photos.
Starting on Wednesday 25th of July 2018 at 1830 UTC, there will be a new 30 minute programme featuring various datamodes, such as SSTV and some of the more complex and interesting PSK modes.
The programme is called ‘SLOW SCAN RADIO’, and will go out on 6070 kHz AM via the transmitter of German based relay station Channel 292, and should be audible throughout many parts of Europe.
It’s easy to dismiss radio as little more than background noise while we drive. At worst you might even think it’s just another method for advertisers to peddle their wares. But in reality it’s a snapshot of the culture of a particular time and place; a record of what was in the news, what music was popular, what the weather was like, basically what life was like. If it was important enough to be worth the expense and complexity of broadcasting it on the radio, it’s probably worth keeping for future reference.
But radio is fleeting, a 24/7 stream of content that’s never exactly the same twice. Yet while we obsessively document music and video, nobody’s bothering to record radio. You can easily hop online and watch a TV show that originally aired 50 years ago, but good luck finding a recording of what your local radio station was broadcasting last week. All that information, that rich tapestry of life, is gone and there’s nothing we can do about it.
Or can we? At HOPE XII, Thomas Witherspoon gave a talk called “Creating a Radio Time Machine: Software-Defined Radios and Time-Shifted Recordings”, an overview of the work he’s been doing recording and cataloging the broadcast radio spectrum. He demonstrated how anyone can use low cost SDR hardware to record, and later play back, whole chunks of the AM and shortwave bands. Rather than an audio file containing a single radio station, the method he describes allows you to interactively tune in to different stations and explore the airwaves as if it were live.[…]

Thomas, I’m sending you a short clip from WWFD 820 kHz in Frederick, MD. It’s America’s only all-digital station, apparently. They are HD only with a relatively eclectic music format. I’m hearing them at my QTH in Harrisburg, PA, about 80 miles or so north of their transmitter which is 4.3 Kw daytime. I sort of doubt they’ll come in at night when they drop down to 430 watts, but who knows.
My experience with HD on MW is that it can be heard at pretty decent distances under ideal conditions but the slightest bit of interference, a lightning strike or someone switching on the lights for example, and it’ll lose the HD lock.
My HD receiver is a Sony XDR-F1HD. It’s well-known as an excellent FM DX machine. What’s not as well-publicized is that it’s a very decent MW receiver as well. All it needs is a good MW loop antenna directly connected to the AM ANT terminals on the back of the radio.
Excellent! Thanks for sharing, Bill. I’m passing by Frederick, MD in a couple of weeks and plan to tune to WWFD in both my car and with the Sangean HDR-14.
