Using the Sony ICF-SW7600GR with external antennas

Many thanks to SWLing Post contributor, Steven Crawford, who writes:

As the 7600GR supplies 6v DC to the external antenna jack to power their active loop antennas there seems to be a great deal of confusion on the web about whether one can or cannot use an external antenna such as a random length of wire attached to the center tip of a barrel connector.

I have been unable to locate the blog entry but I seem to remember you discussing this in one of your posts. In it you mentioned you had built a widget that killed the voltage and allowed you to use the external antenna of your choice. I would appreciate your thoughts on a random wire to center tip antenna and details of the widget you built when you have time.

Thank you for your question, Steven.  I hope a reader can help point to the post you’ve mentioned.  I believe I recall reading this in a guest post–I know I’ve never used a device to kill the 6V phantom load in the antenna out jack.

 

I suppose I’ve (incorrectly?) assumed the Sony would only push voltage out if connected to the Sony AN-LP1 (see right).

I know I’ve used a number of antennas with the ICF-SW7600GR: long wires, the PK Loop, The EF-SWL, the NASA PA 30, and even a rather large multi-band dipole when I recorded the final broadcast of RNW. I’ve never experienced a problem, nor damaged the antenna/receiver as of yet.

Can anyone shed some light on this? Please comment!

Sony ICF-SW7600GR: New and open box units on sale via Blinq

SWLing Post readers know that I’m a big fan of the, now discontinued, Sony ICF-SW7600GR shortwave portable. I try to post ‘7600GR deals when I find them and they’re beginning to become more scarce as retailer inventory depletes.

This weekend, I found another deal via Blinq/Amazon.

They have a number of new ICF-SW7600GRs for $138.39 and about 3 (at time of posting) listed as “Open Box” for $108.39.

Click here to view on Amazon.

I’ve bought a number of items via Blinq (directly and through Amazon) in the past and found that the retailer is not only reliable but has a very generous return policy if you’re not satisfied. You can buy from them directly or through Amazon with confidence.

Mark spots shortwave radios in the series “Helix”

Many thanks to SWLing Post contributor, Mark Hirst, who writes:

I spotted a Sony ICF-SW7600GR in episode 5 of the Netflix bio-thriller ‘Helix‘:

On a roll, I spotted another shortwave radio [in a different scene].

You’ve got sharp eyes, Mark! Thank you for sharing.

Can anyone identify the solid-state receiver in the second screen shot?

I know I’ve seen this model before, but I can’t recall the make or manufacturer.

Now’s the time to grab longwave DX!

If you’ve been wanting to log France Inter as longwave DX, you’re running out of time. France Inter is shutting down their 162 kHz longwave service on December 31, 2016.

I’m grateful to SWLing Post contributor, Ron, who has persistently reminded me that these are some of the last days to catch France Inter as LW DX here in North America.  Indeed, he shared a bit of interesting and encouraging news a couple weeks ago:

On the Radiodiscussions DX forum, Jim Farmer over in San Antonio got and recorded France Inter on 162 khz using a PK loop and Sony 7600GR.

The PK Loop he’s referring to is this one and, of course, the Sony ICF-SW7600GR is one of my staple portables.

While I’d love to try to grab France Inter with my Sony, my schedule makes it very difficult to arrange. Fortunately, I have SDRs which allow me to record spectrum throughout the night, then review the recordings in the morning.

Throughout the month of December, I’ve been recording a small chunk of longwave spectrum–with my WinRadio Excalibur–during the night and reviewing it in the morning in hopes that I could grab an opening from France Inter.

I was rewarded on December 19, 2016 around 0300 UTC. Though there was atmospheric noise that night in the form of static crashes, I snagged France Inter on 162 kHz.

My spectrum display from the Excalibur.

The 162 kHz carrier was barely above the noise floor (see above), so it was certainly weak signal DX. Here’s an audio sample:

When that short LW opening happened, I was also able to snag Medi 1 from Morocco on 171 kHz. Again, not fantastic copy, but I’m happy:

Mind you, both France Inter and Medi 1 only transmit at 2,000 watts–that’s flea power compared to our shortwave broadcasters. It’s amazing those signals can even hop the Atlantic.

Correction…an SWLing Post reader, qwerty.am, comments:

Actually, the power of France Inter and Medi1 is 2000 kW and 1600 kW respectively. So the power of most SW broadcasters should be called a “flea power” in comparison to what is used on longwave. The smallest output on LW band in Europe is 50 kW, it’s used by Denmark and Czech Rep. The 162 kHz transmitter is closing on Dec 26th, according to the latest news.

Wow!

Again, if you’d like to grab  longwave stations before they disappear, now is the time! Our LW broadcasters are disappearing rapidly. Fortunately, winter (here in the northern hemisphere) is the best time to chase LW DX.

Thanks, again, Ron for your encouragement! I’ll keep listening and recording!

Holiday Deals: Open Box Sony ICF-SW7600GR for $113 via Amazon/Blinq

Traveling with my Sony ICF-SW7600GR in Taos, New Mexico

Regular SWLing Post readers know that I’m a big fan of the, now discontinued, Sony ICF-SW7600GR shortwave portable. Recently, I even wrote a post about finding some of the remaining units online.

This morning, I noticed that Amazon.com has some “Used – Like New” ‘7600GRs available via the seller Blinq for $113.39 shipped. At first, I didn’t notice the deal because it’s buried in the page: simply go to the Amazon product page, scroll down and click on “Used & new from $113.39 & FREE shipping” on the right side of the page. There, you’ll see the current offerings, if still available:

icf-7600gr-amazon

Since this offering is available via Blinq, I then searched the Blinq.com website and found the same deal:

blinq-sony-icf-sw7600gr

 

I’ve bought a number of items via Blinq (directly and through Amazon) in the past and found that the retailer is not only reliable but has a very generous return policy if you’re not satisfied. You can buy from them with confidence.

Each time a ‘7600GR deal pops up, I’m very tempted to bite the bullet. I have two working units already though–“Coals to Newcastle” as they say!
