Surprisingly Capable: Mario Checks Out the Raddy RF750 Plus

Many thanks to SWLing Post contributor Mario Filippi, who shares the following review:


Raddy RF750 Plus AM/FM/SW/NOAA Radio

by Mario Filippi

I purchased one of these tiny radios several months ago. It’s my daily go-to AM broadcast band  radio.  So far, it performs excellently on AM.  Using the rotatable ferrite antenna,  I’ve received stations as far away as Chicago and Detroit at night.  FM broadcast band capability is also excellent in my experience for such a small radio.  As for SW, the only luck I’ve had is with powerful broadcasters when the Raddy’s telescoping antenna is connected to an outdoor ham antenna.  It receives local NOAA WX as good as any other radio I’ve owned.

Raddy 750 Plus

The case is all metal, feels nice and hefty in the hand.  A shade under a half-pound in weight. 3 3/4 inches high (approx. 9 cm) with attached rotatable antenna.   The speaker size is exceptional for such a small radio and the audio’s very acceptable to the ear.  The speaker grill can be used to tune the radio manually by the way. The fit and finish are excellent.  Has a rechargeable battery with included USB charging cord.  Excellently-written 25-page owner’s manual in English.

?I use the Raddy app to control the radio.  You can opt not to use it though.  You’ll definitely need to read the manual then, due to the plethora of options.

Raddy’s SmartPhone App Works Great

All said, since I bought this radio mainly for daily AM broadcast reception and occasionally checking NOAA weather, I’m very pleased.  Price is very reasonable, mine was under $40 at the time.

Wonder if anyone else has one of these radios and what their opinion is?  Thanks for reading and 73’s.

You can purchase the Raddy RF750 on Amazon.com or at Radioddity.com (affiliate links).

Exploring the AM Graveyard Frequencies

Many thanks to SWLing Post contributor Dennis Dura for sharing this article from Radio World which delves into the legacy of AM broadcasting in “Digging Up the AM Radio Graveyard.”

This piece explores the so-called “graveyard frequencies”—those crowded AM channels where hundreds of local stations once operated at night, all competing in a sea of overlapping signals. It’s a great read for anyone interested in radio history, signal propagation, and the enduring mysteries of the medium wave band.

2026 Tesla Standard Model Y and Model 3 trims will eliminate AM and FM tuners

Many thanks to SWLing Post contributor Dennis?Dura for sharing this article from Radio?World, which reveals that Tesla will eliminate AM and FM tuners from its 2026 Standard Model Y and Model 3 trims—a move the National?Association?of?Broadcasters calls a “disservice to millions of drivers” who rely on broadcast radio for news, community and emergency alerts.

Radio World: John Kean Examines Modern AM Interference Challenges

Many thanks to SWLing Post contributors Dennis Dura and Frank Howell for sharing this article from Radio?World, which examines the persistent and growing problem of AM?band interference. In “John?Kean Explores AM Interference Issues,” Kean outlines how noise from switching power supplies, urban clutter and even future EV wireless-charging technology are threatening reception quality for AM broadcasters — and offers pathways for engineers and regulators to maintain AM viability.

Preserving Radio History in Your Community

Many thanks to SWLing Post contributor Dan Greenall, who writes:

I have lived in southern Ontario, Canada my entire life, have been DXing since the late 1960’s and have held the amateur radio call sign VE3HLC for over 50 years.  Most of this area’s AM broadcast stations had been considered “pests” over the years as I searched for more distant targets, until recently, when many of these began quietly slipping from the airwaves.  While this opened up some new frequencies to DX, I soon began to feel that I had lost some old friends, many that I had known since childhood.

When I retired in 2018, I decided to spend a little time trying to preserve some radio history of stations in southern Ontario communities that have played a part in my life. This might include audio clips, QSLs, station booklets, and other types of ephemera, and I would try to place this information where it could be easily accessed by future historians or anyone else who is interested.  In the end, I chose to use the Internet Archive (archive.org), where most uploaded information can be viewed (or heard) and downloaded for free.

CFPL, London, Ontario   980 kHz (still on the air)

“Communications in the Community” is a hardcover limited edition (2000 copies) souvenir book printed in 1966 by the Special Printing Unit of The London Free Press in London, Ontario, Canada.  It includes historical information about the London Free Press (newspaper) and CFPL radio and television.  I was lucky to find this item at a church rummage sale nearly 20 years ago.

CFPL began its life as CJGC in 1922. I acquired one of their QSL cards from 1925 through an eBay purchase a few years ago.

CKOC, Hamilton, Ontario 1150 kHz (still on the air)

CKOC radio in Hamilton also started up in 1922.  My parents met while working at the station in the late 1940’s.  My brother and I (both radio amateurs), along with a few friends were given permission to operate on “Field Day” weekend in 1985 from their old abandoned transmitter site at Elfrida, Ontario.

This area has long since been developed to build homes and shopping areas.

“This is Hamilton, Ontario and the story of broadcasting station CKOC” is an undated booklet (I am guessing circa 1950) that I was able to purchase on eBay.  Also found on eBay were two verifications, one from 1931 and the other from 1983.

You can find these scans and more by following this link.

CKNX, Wingham, Ontario 920 kHz (still on the air)

This station began in 1926 using the unusual call sign 10BP.  It would remain that way until 1935.  I managed to secure this QSL from 1932 through eBay, signed by its founder W.T. “Doc” Cruickshank.

Interesting stories of how the station began can be found at this link.

CKCR, Kitchener-Waterloo, Ontario 1510 kHz  (no longer on the air)

In 1924, this station began briefly in nearby Brantford, Ontario. It quickly moved to Kitchener-Waterloo and existed until 1965 when it became CKGL.  The CKCR call sign was picked up later in 1965 by a station in Revelstoke, BC.

Another eBay purchase, I found this QSL with a not-to-scale map of southern Ontario from 1934.

More Ontario QSL’s can be found in my broadcast band gallery at this link: https://archive.org/details/ckoc-hamilton-on-1983

I would encourage others to save parts of the local radio history in their city, state, province or country and give back to the hobby that we have enjoyed for so many years.   I would also be happy to hear about any efforts you have made!

Senate Report Flags Public Safety Risks in Removing AM Radios

A recent Radio World article summarizes a U.S. Senate Commerce Committee report raising concerns about the removal of AM radio from new vehicles. The report highlights AM radio’s role in national emergency alert systems and notes its low cost to manufacturers. It recommends Congress consider legislation to ensure AM capability remains standard in future vehicles.
