Bill’s simple Sony SRF-59 passive loop antenna modification

Sony-SRF-59-AM-Loop-Antenna

In reference to our previous posts about the Sony SRF-59 ultralight receiver, SWLing Post reader, Bill Mead, writes:

“As someone who doesn’t normally open the backs of radios, this is my mod on my ultralight. All it takes is a bit of electrical tape to hold the belt clip on the loop.”

That is, indeed, a brilliant and simple mod. The SRF-59 inductively couples to the loop antenna, so no soldering is needed; simply tape the belt clip to the loop, making sure the position is convenient for tuning the SRF-59 and the loop’s capacitor.

You can find passive loop antennas ranging from $19 to $50 US. The Grundig AN-200 and the Terk AM Advantage are two models currently on the market. Here are a few places you can check prices:

As usual a very interesting post.

I sold most of my collection of receivers some years ago but I’m still interested in AM DXing and especially ultralight DXing (thats why I have three SRF59).

May I draw your attention to other receivers as well?

The famous CXA1129N chip has been built into the SRF-S84 and into the SRF-18 as well. I use the SRF-S84 during sports. As the ferrite rod is even smaller than in the SRF-59 AM reception is a little bit less sensible but FM shines with mega sound.

The SRF-18 is my favorite travel radio!! It runs endlessly on two AA-cells, has built in stereo speakers, audio-in and audio-out, a rather large dial which is easy to use and due to a larger ferrite rod it is very very sensitive on medium wave.

Thank you, Peter! Perhaps the SRF-18 can take the place of the SRF-59 as an affordable MW ultralight that is still in production. The Amazon price for the SRF-18 is $32 US–quite affordable. While I don’t need another ultralight, that price makes it very tempting.

The SRF-S84 reminds me of a super compact radio I used to sneak into my fifth grade class. I would listen to the radio during class by concealing the receiver in an interior jacket pocket and snaking the earphone cord through my sleeve. I would then rest my head on my left hand where the earphone was conveniently located.  Somehow I never managed to get caught.

While I’m sure my education suffered a little that year, it still makes for good memories!

Robert’s modified version of the Sony SRF-39FP

srf-39fp

Many thanks to Robert who comments on our post about the Sony SRF-39FP:

Here’s a Suped-up Version of the SRF-39FP made for me by Gary DeBock. [see above]

As if the Prison Radio wasn’t already good enough…this 7 Inch loopstick gives it even more bang four the Buck!!

I call this Prison Radio the “Frankensteiner Prisoner” thus the 39FP monicker.

Robert, that’s a great SRF-39FP modification indeed and I bet it improves reception (and nulling abilities) quite dramatically. Plus, it was built by Gary DeBock–no doubt, a quality mod! Thanks for sharing!

Pocket DX: Finding the Sony SRF-59 and SRF-39FP

Sony-SRF-59-and-Sony-SRF-39FP

I have two of the Sony SRF series pocket AM/FM radios: the grey SRF-59 and the clear SRF-39FP.

The venerable SRF-59 has long been one of the least expensive, quality analog AM/FM receivers on the market. I originally purchased one new for $14.95 US including shipping. Here’s a short review I made of the ’59 several years ago.

The SRF-39FP–the model with the clear case–was specifically designed by Sony radio for the prison market.

A couple years ago, someone on eBay had a lot of Sony SRF-39FP units on sale–I jumped at the opportunity to buy one new-in-box for $20 US. The entire lot of SRF-39FPs sold in a matter of hours. Indeed, the ’39FPs were so popular, by the time I prepared a post for the SWLing Post, the seller had already sold out. (I’m kicking myself for not buying at least one extra–!)

While most ultralight radio enthusiasts would give the SRF-39FP a performance edge over the SRF-59, they’re essentially the same radio–especially if you tweak the SRF-59 like my buddy Dave Richards did.

Several weeks ago, while Steve researched the reason he was hearing shortwave broadcasters on his SRF-59, he also discovered that the SRF-59 had been discontinued and selling in many places for three or four times the original price.

He found one vendor still selling the SRF-59 for $14.99 plus shipping. I placed an order with this vendor over a month ago, but still haven’t received the product because the vendor hasn’t taken delivery of the final batch of units from Sony. I’m in contact with this vendor and when/if the units are received in stock next week, I’ll post an update here on the SWLing Post (if interested, follow this tag).

If you’re in the market for a Sony SRF-59, here are a few places you may find one new or used:

(If you know of other good suppliers, please comment!)

The SRF-39FP has a clear housing which is meant to prevent prison inmates from using it to smuggle contraband.

If you would prefer the Sony SRF-39FP, the only source I know of is eBay. When one becomes available, it typically sells for $45-50 US.

Click here to search eBay.

To be clear: while the SRF-59 is an exceptional ultralight receiver, $45-50 US would certainly place it in a price class with other excellent ultralights.

Mini DXpedition: Oxford Shortwave Log and the Sony ICF-SW55

Sony-ICF-SW55

SWLing Post reader, “Oxford Shortwave Log” recently noted the following on our Facebook page:

“Hi there, I received some very nice feedback regarding almost perfect reception of Radio Australia during a mini DX-pedition into the Oxfordshire countryside and thought I would share it.”

“I use a (now vintage I guess!) Sony ICF-SW55 and a 25 metre long-wire. There are lots more videos at on YouTube channel: Oxford Shortwave Log

Great proof that Mini DXpeditions can pay off!

Sounds like that Sony ICF-SW55 performs admirably–it is certainly a classic portable.

I remember when the ICF-SW55 was introduced in 1993-1994; back when I was doing my undergraduate studies and had no funds for it. In the 1990s, Sony’s portables almost seemed to be sent to us from the future–large informative displays, advanced memories, and incredible portable performance were the hallmarks.

On eBay, you’ll find that the ICF-SW55 still fetches a high price.

OSL: thanks for sharing the videos!
