Frank finds a Sony ICF-SW7600G/GR replacement antenna

Many thanks to SWLing Post contributor, Frank, who writes:

Thomas,

I have asked for and received help from your members a couple of times during the last year. I am sending this to you in an effort to “give something back” to your members.

I managed to stupidly break the built-in whip antenna on my Sony 7600GR and looked for a replacement. Several are on eBay for 5- 60 dollars which is a bit steep.

I eventually tried one (for $20) in the link below from eBay:

It arrived very quickly (under 2 weeks from China) and it simply went into the radio with no problems and it works very well.

I am not a radio HAM or electronics expert so it may not be perfect but to me the reception is at least as good as the original.

If anyone needs one, it would be well worth trying.

Regards,

Frank from England

Thanks so much for sharing this useful tip, Frank!

Playing music with computer-emitted interference

Here’s my Mac Book Pro (2010 model) playing Mary Had A Little Lamb over the radio, by modulating the RFI (Radio Frequency Interference) produced by it and other computers. As picked up on a Sony 7600G receiver. I found the best reception was on the long wave band, although I could continue to hear it well above the AM (medium wave) band, past 1700 kHz. The signal was pretty much everywhere, no matter where I tuned, in 1 kHz steps.

Picking up radio emissions from computers is one method that can be used to spy on them.

That is fascinating, Chris. While I was well aware that computers and mobile devices (of all stripes) produce RFI, I had no idea that it could be used for spying. I love how you’ve manipulated this interference to play a tune! What a creative hack!

Chris field records NHK while traveling in Peru

SWLing Post reader, Chris, has just shared a recording of NHK World he made while traveling in Peru on Monday (April 21st, 2014).

Yes, that’s his photo above taken in the picturesque coastal town of Máncora. Can you tell I’m envious?

Chris recorded this broadcast starting at 10:00 UTC on 9,625 kHz with a Sony ICF-SW7600G and using a Sangean ANT-60 antenna. The actual recording was made with Chris’ Sony ICD SX712 digital recorder and he uploaded it using a Dell Windows 8.1 (8 inch) tablet.

That, Chris, is a nice field recording combo!
