My Story With Radios

by Rawad Hamwi

My passion for the world of radios started 15 years ago when I “accidentally” got my hand on a vintage Sanyo U4SS radio/cassette player.

At that time, FM didn’t mean that much to me, and to make the long story short, it was anything but interesting! So let’s move on and discover that SW band.

I was totally shocked with the findings! Music of different genres, languages I heard for the first time ever, bizarre sounds, Morse broadcasts, etc.. However, the most chilling and exotic thing which caught my attention was that weird “presumably” number station, broadcasting an endless and never-ending loop of “Alpha, Bravo, Charlie”! I could never ever forget that! That SW “thing” was quite interesting, isn’t it?

Back in 2004, the shortwave band was HEAVILY crowded with so many stations from all over the globe, and the idea of being able to listen to all of that stuff without moving away from your couch was something interesting!

Over that period, I owned some portable shortwave receivers/antennas, starting with the Grundig G3, Tecsun PL-660, and last but not least, the trust-worthy Sony ICF-SW7600GR with Sony AN-LP1 active antenna and the Terk Advantage AM antenna, that’s just to name but a few.

And now, drum roll, please!! May I proudly present the legendary Zenith Solid State Trans-Oceanic Radio Receiver. That armored tank is far from anything portable in today’s terms! But still, its reputation can’t be questioned.

Last Christmas (Dec – 2018), my uncle gave me his Sony ICF-7600D which was in a perfect cosmetic/working condition. It was sitting in his drawer for almost 20 years without being used! Operating that “piece of history” is satisfying!

A year before, my grandparents gave me their “Made in Japan” Sony ICF-SW11. You may notice that screen protector over its display, it did a good job in disguising some fine scratches. This radio had been used occasionally, though it’s a solid performer.

Whoa, lots of radios to choose from! A decision was made by giving the Grundig G3, Tecsun PL-660, and the Sony ICF-7600GR/AN-LP1+Terk Advantage a short break and keeping them in my hometown (Lebanon). Both the 7600D and SW11 will join me in Saudi Arabia for at least 6 months until I return back.

Here comes the turning point! Last month, there was a great deal on eBay. A decent Sony ICF-2010 with an above-average condition. I didn’t think twice before buying it, I wanted that radio a long time back and at last, at last, it’s here..sitting on my desk!

To add some nostalgia to the scene, a brand-new vintage “Made in Japan” Seiko World Time Rate Exchanger was listed on eBay, and you can predict what happened next! It was a beautiful add-on.

It joined my vintage Casio DQ-580 alarm clock that was set to display UTC time

Unfortunately, Sony ICF-2010s had some issues with their front-end FET if they were hit by a strong static charge. The solution was by building a DIY protection circuit, based on a schematic available online.

The random wire antenna I use is connected to a 9:1 impedance transformer for the purpose of impedance matching, and to add more protection, a lightning arrester joined the setup. Furthermore, some folks said that winding the 50-ohm coaxial feed cable to a toroid could improve the reception, so..why don’t I give it a try?!

Finally, the BNC male plug coming out of my protection black box is coupled with a female BNC to male 3.5 mm mono adapter which goes towards radio’s external AM antenna socket.

Now, why don’t I utilize the FM band too? I have two in-car FM transmitters. The first one is connected to a satellite receiver to transmits its audio feed via a RCA to 3.5 mm stereo cable, and the second one is attached to a Chromecast Audio device.

-1-Turn on the transmitter
-2- Go to TuneIn
-3- Look after “Conyers Old Time Radio”
-4- Pipe that audio stream throughout Chromecast
-5- Set your radio’s sleep timer to 30 minutes and…I wish you a very good night!!


iCluster ($2.99 for iPhone and iPad) is a useful tool I regularly use when listening to amateur bands over shortwave DXWatch.com and DXMaps.com can be helpful too.

Google’s Play Store contains much more radio-related apps than Apple’s App Store. Below are my main drivers for decoding digital transmissions.

When it comes to rechargeables, my choice for AA size is Eneloop and Energizer for D size

The Internet contains enormous easy-accessible resources but having a hard copy isn’t a bad idea I guess!

That’s all folks, thanks for reading and if you think there are some rooms for improvements, sharing your ideas will be much appreciated.


Thank you for sharing this, Rawad!  You’ve amassed a fantastic collection of portable radio gear and all of it seems to be in excellent shape! I think it’s brilliant that you took the time to build antenna protection for your Sony portables–so many people don’t think of this and end up using an antenna that’s too long and static zaps their FET. 

Again, many thanks for sharing your story with us.

Rawad takes a peek inside the Sony ICF-SW11

Many thanks to SWLing Post contributor, Rawad Hamwi, who writes:

Recently, I’d acquired a vintage Sony ICF-SW11 from my grandparents and it was in a good shape. After removing its back cover, I did some housekeeping inside and took couple of photos:

I know that this radio is somehow a basic shortwave receiver, lacking some features such as a dedicated external antenna jack.

While waiting this radio to be delivered, I was searching the internet for a hack or trick in which I can utilize my existing long wire antenna and use it on this radio for MW specially. Usually, I depend heavily on my 30 m long wire antenna since the noise level inside my room is somehow high. But I found nothing.

I was amazed when I plugged my 3.5 mm external antenna jack only half way through the Sony’s audio jack. At this moment, the reception was enhanced dramatically on all the bands (FM/LW/MW/SW). I’m not sure how and why but this trick seems to be working! No more noise, the device was pulling signals out of the long wire directly

I found that quite cool. This simple hack had solved my noise problems and I would recommend it to all Sony ICF-SW11 owners. I hope that this wouldn’t affect my device badly on the long run!

One final [note], as far as I know, the telescopic antenna is designed for the FM and SW on this radio. However, whenever I touch that antenna while tuning in to MW, I notice some changes in the signal strengths. Maybe the telescopic antenna works alongside with the ferrite antenna? Or there may be some sort of a short circuit inside?

Thanks for sharing your notes and photos, Rawad. The ICF-SW11 is a great little analog radio–I have one here at SWLing Post HQ and plan to give it to an elderly friend when I next see him. It’s such a simple radio to operate.

In terms of improved performance on MW when you touch the telescoping antenna, I suspect you’re grounding the radio and that’s giving reception a boost. Maybe that’s what’s also happening when you add the longwire to the audio jack?  Comments, anyone?

Francis loves the Sony ICF-SW11

Many thanks to SWLing Post reader, Francis, who left the following reply on our Battery Endurance Contest Results post:

Dear Thomas,

I have been using a Sony ICF-11 for 5-6 years now, still sold new at 50-70 euro. It’s analog and rather well featured: FM (stereo on earbuds), LW, AM, and 9 SW bands. It runs on 2 cheap AA batteries I get in low-cost supermarket, for sure not the best ones.

Using it at least one hour a day on the speaker, I have to change the batteries after 9-12 months. I am convinced a set of good Duracell or Energizer batteries would last some more months.

Sony_ICF-SW11
I am not a radio expert, but I am quite pleased with its audio performances, specially on LW (used most of the time ) and AM, where it is vastly superior to my Tecsun PL-660. SW looks OK for what I can say from listening quite occasionally these bands. I would be curious to see a serious review of this Sony to know how it compares with others, but I didn’t find any on the web so far (hint?). [Yes, Francis, hint taken!]

Sony_ICF-SW11_2
I am so pleased with this small radio that I recently bought a second one as a spare.
Thanks for your very interesting blog and reviews.
Francis

Thank you, Francis, for sharing your thoughts on the Sony ICF-SW11 and your photos as well!

It appears Amazon.com (US) has a few options for ordering a Sony ICF-SW11–click here to show search results. Prices vary between $50-$55; Amazon even has replacement telescopic whips available.

Of course, an eBay search will also uncover a number of SW11’s.

I searched the web, but couldn’t find many other retailers selling new ICF-SW11’s. It appears many of the ones on Amazon are imports from Japan.

At $50 shipped, it seems like a bargain to me, so I just pulled the trigger on one.
