Would a Sony ICF-SW07 outperform a modern DSP radio?

Many thanks to SWLing Post contributor, William, who asks:

Hello,

Firstly thank you for the blog – I have been reading occasionally for several years – it’s really interesting.

I live in the UK. I own (was given as a gift many years ago) a Sony ICF-SW07 and have been playing with it for the first time in the while.

I’m wondering if you remember it or ever used it, and if you can give me a rough idea if a new radio, such as the latest Tecsun, have considerably better sensitivity – for SW and MW – or not?

Many thanks.
William

Thank you for your question, William!

To my knowledge, I’ve only used a Sony ICF-SW07 once and it was from a hotel room at a radio convention, so not ideal for really gauging anything other than economics and superficial qualities. I do know that my friend held it in high regard.  My inclination would be to say that the ICF-SW07 should hold its own and potentially even outperform many modern (late-model) portable receivers.

I do know this, William: in good condition, that ‘SW07 will fetch top dollar. I’m not sure I’d ever let go of it!

Sony ICF-SW07 owner comments and feedback?

SWLing Post readers: If you own the ‘SW07 and would like to share your thoughts with William, please comment!

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!

Many thanks to SWLing Post contributors Kris (G8AUU), Tracy Wood, and Dan Robinson for the following tips:


Aging brothers in Hyderabad run last radio repair shop in southern Indian state (Arab News)

NEW DELHI: “Mahboob Radio Service,” reads the faded panel on a small repair shop near the 16th-century Charminar mosque in the heart of the old town of Hyderabad.

The shop, which has been open since 1948, is filled with thousands of radio sets stacked in the small space where two aging brothers have been repairing radios for as long as they can remember.

The brothers, Mohammed Mujeebudin, 82, and Mohammed Moinuddin, 71, learned the craft from their father, who started selling and repairing radios in the 1920s after a trip to Bombay, where he bought his first set.

“My father started Mahboob Radio Service from Dabeerpura in Hyderabad before moving to the present location in Chatta Bazar in 1948,” Moinuddin said.

He remembered his father’s most prominent customers, such as Viceroy Mir Osman Ali Khan, who ruled Hyderabad until the princely state’s merger with India.

“He was our client, and we would repair his radios. Once the work was done, we would deliver the radio to the palace and receive some 20 or 30 rupees,” Moinuddin recalled.[]

TV station owner AméricaTeVé owner exits Chapter 11, to buy radio station (Bizjournals.com)

The companies that own the AméricaTeVé and Teveo television stations have exited U.S. Bankruptcy Court and are preparing to make an acquisition.

America-CV Station Group, Caribevision Holdings, America-CV Network and Caribevision TV Network all filed Chapter 11 reorganization in 2019. The Hialeah-based companies own local stations WJAN (Channel 33 AméricaTeVé) and WFUN (Channel 48 Teveo), along with WJPX (AméricaTeVé Puerto Rico) in San Juan, Puerto Rico, and WPXO in New York.

[…]”América Teve has exited its Chapter 11 reorganization ahead of schedule and has paid off all of its debtors,” said attorney Marcell Felipe, who represents the company. “The company was recapitalized with new equity funded by Carlos Vasallo and the refinancing with Abanca of its valuable real estate holdings.”

Felipe confirmed that the company signed an agreement to purchase Radio Caracol 1260 AM in Miami to create a synergy between the radio station and its TV stations. The Spanish news/talk radio station was being sold by Grupo Latino de Radio, a subsidiary of Spanish media conglomerate PRISA.[]

SWLing Post contributor, Tracy Wood, notes: “An interesting medium wave note for SWLing Post readers. AM 1260 WSUA in Miami (50kw day / 20kw night) has been used in the past to relay Radio Martí for a few hours at night.”

GBT Completed Prototype Design of its Long-Range Radio Mobile System (Intrado GlobeNewswire)

SAN DIEGO, April 08, 2021 (GLOBE NEWSWIRE) — GBT Technologies Inc. ( OTC PINK: GTCH ) (“GBT” or the “Company”), completed its prototype design of its long range radio mobile system. The prototype mobile unit will be a high-performance radio transceiver system that is designed for data and voice applications. It is expected to enable data and voice communication for long range applications targeting telemedicine support for the Company’s qTerm vital device including audio.

The design of the prototype mobile unit includes a transceiver targeted for systems to operate under licensed/unlicensed radio frequency bands, enabling ultra-long-range applications. The unit is designed to communicate in the HF (High Frequencies) frequencies bands to establish connection with a base unit transceiver through repeater unit(s) to reach ultra-long range. High clarity, signal reliability and security is expected to be achieved through the implementation of advanced circuitry within the system’s components. The design includes embedded software to manage the data and audio communication including data transfer to a backend server to process data. The design also provided for the mobile unit’s design, size and interface, taking into consideration performance and mobility. The operation of the mobile unit is expected to be done via an LCD touch screen providing user’s friendly interface and ease of use. Upon getting team’s FCC certification, an extensive mobile unit’s testing will start. GBT plans to test the entire system within a large city limits and national ranges.

“We are glad to announce that we completed the design of our prototype long range radio mobile unit. The prototype mobile unit is a key component since it is targeted to be portable aiming to bring modern life services around the globe. The design contemplates an acceptable physical size to be carried coupled with a high-power energy source and long range capability. As the system is targeted to work with the qTerm vital device, the design contemplates users being able to send vital information to professional health authorities for quick review and recommendations. In addition, the design has incorporated a voice communication will be available to discuss further steps and actions. We believe that in our days and age everyone should have access to modern amenities and the key is global communication. For us, the most important contribution of such system is the capability to save lives by enabling health and emergency services anywhere on earth” stated Danny Rittman, the Company’s CTO.

There is no guarantee that the Company will be successful in researching, developing or implementing this system. In order to successfully implement this concept, the Company will need to raise adequate capital to support its research and, if successfully researched, developed and granted regulatory approval, the Company would need to enter into a strategic relationship with a third party that has experience in manufacturing, selling and distributing this product. There is no guarantee that the Company will be successful in any or all of these critical steps.

New Zealand auction includes collection of 400 vintage radios

Many thanks to SWLing Post contributor, Jason Walker, who writes:

Dear Thomas,

I noticed a New Zealand news article that may be of interest to SWLing Post readers.

Approximately 400 vintage radios are to be auctioned in Nelson, New Zealand. Whilst I use more modern Tecsun radios, the article will be of interest for vintage collectors. Many of the Radios are New Zealand made and rare.

Links below include a video and news article.

Radio and Collectables Auction
17 Hereford Street (off Songer St)
Stoke, Nelson
Saturday 10 April, 2021

AUCTION STARTS AT 11am
Viewing from 9am day of auction
and, Friday 11am – 3pm

More information: https://jwauctions.co.nz/upcomingauctions.html

Thank you, Jason. Even though this auction has been widely publicized in New Zealand, the collection is so massive, I imagine bidders will be walking away with some excellent bargains. If I lived in NZ, I would certainly be a part of the bidding. I’d love to have an NZ-made receiver.

I really like the following quote from the Stuff.co.nz article:

The widower of the man who stockpiled the radios told Walker her husband had collected the stash from all over the country.

“His wife was a wee bit disappointed she didn’t know he had half the radios because he used to keep hiding them.[“]

How many of us can relate to that last statement? Let’s face it: par for course, right!? 🙂

Printed circuit board information for Sony CRF-320 panel light mod?

Many thanks to SWLing Post contributor, Brian, who writes with the following inquiry:

I found a pic of a printed circuit board, based on Mr. Carlson’s Sony CRF-320 panel light mod, on the Yahoo 320/330 fan page but no board dimensions or component values.

I plan to order a bunch of these so if anyone can sort out some measurements on this board or are interested in obtaining a board, please comment. I am a novice in this and am unsure of the component values. I have wired up an electric guitar, so this I anticipate will be less complicated.

Post readers: If you can help Brian with this info, please feel free to comment!

Dan spots a rare Collins 51S1 LTV G133 F military receiver on eBay

Many thanks to SWLing Post contributor, Dan Robinson, who notes:

This military version of the 51S-1 receiver is almost never seen on the used market.

Click here to view on eBay.

Thank you, Dan! The seller claims that this radio is fully working with tubes replaced and has undergone a complete alignment. Hopefully, caps have been replaced as well.

I’ll admit: if I had the space, I would add this rig to my collection in a heartbeat, although I expect the price of this unit will far exceed my budget!  It is a beauty, though.

Video: This radio enthusiast has quite the collection of vintage radios

Many thanks to SWLing Post contributor, Tom Daly, who shares the following:

Thomas,

If you want to drool over some old SW radios take a look at this guys
incredible collection:

He’s going to be selling a bunch of them but unfortunately he’s in
Australia. Or maybe it’s fortunate that he’s in Australia because it’ll
prevent me from spending way too much money loading up on some of these
oldies.

Tom Daly

Ha ha! Yes, I’m happy he’s on the other side of the planet from me, but this is a great opportunity for our readers in Australia! That’s an amazing collection.

Dan notes a spike in Zenith Trans-Oceanic prices

Many thanks to SWLing Post contributor, Dan Robinson, who notes:

There appears to be a spike in Zenith Trans-Oceanic sales. The recent eBay sale of a D7000Y for $900 sparked a number of new auctions by sellers seeking to take advantage of this apparent
trend.

The following D7000Y was listed with a $900 Buy It Now price by someone obviously
cashed in.

Click here to view on eBay.

Wow! I’m curious what could have encouraged this spike in prices. I have a Trans-Oceanic but will not sell it because it was my first portable radio. With that said, if there are readers who’ve considered parting with theirs, this might be the right time. Thanks for the tip, Dan!
