Can you help George identify the mystery pip?

WWV format

WWV format

SWLing Post reader, George (NJ3H), writes:

I quite often see a spike in the evening on 4996 khz. From the listing, this is suppose to be RWM, in Moscow, a time signal station.

When I listen on remote receivers in Poland and Denmark, I do not hear time pips, but rather just hash.

On my Perseus, I can watch the spike go up and down each second. This makes me think it is caused by WWV. However, the 29th second seems to make the spike move up, even though WWV doesn’t have a pip at second 29. The remote receivers in Europe that I just mentioned do not have any time pips being broadcast. Does WWV cause a signal on 4996?

Can you shed any light on 4996? Should we be able to hear RWM in the Eastern US?

Good question, George, and I’m hoping a reader can shed some light on what you’re seeing on the spectrum display. I’m not sure what could be causing the 29th second spike unless it’s WWV transmitting a sub-audible tone.

Pete gives Kaito high marks for customer service

PL-880 (1)

SWLing Post reader, Pete Jernakoff (K3KMS), writes:

“I purchased two PL-880 radios from Amazon about a year ago and before the soft muting issue became a hot topic. Both of my radios (8819 firmware version) suffered from this most annoying problem but it wasn’t until I started reading your excellent blog that I learned of the cause.

About two weeks ago, I called Kaito Electronics USA and asked if they could upgrade the firmware on my two radios to the 8820 version. The person I spoke to said (paraphrasing) “Sure! Send them to us any we’ll perform the upgrade for free. All you do is pay for the return shipping.”

So off the radios went to Kaito. About 10 days later I had them back with the new firmware installed. The return shipping was $10. Weak MW and SW signals are now easy to listen to: no soft muting issues at all. Kudos to Kaito for agreeing to perform the upgrade for me. My dealings with them were thoroughly pleasurable.”

Thanks for sharing that great experience, Pete! You’re right–the 8820 upgrade is certainly worth the shipping costs and I’m happy to hear Kaito makes the process so easy.

Shortwave Shindig Rebroadcast: March 7, 2015

ShindigLogoWhiteI’ve just learned via @shortwaveology that the Shortwave Shindig will be rebroadcast on Saturday March 7, 2015 from 10:00-11:00 PM EST (that’s Sunday from 0300-0400 UTC) via WRMI on 7,570 khz.

Those of you who tuned into the live show last Friday noted that the audio dropped out at times–this was due to a flaky Internet connection at the hotel where the ‘Shindig was held. You will hear the full show, without interruption, in this rebroadcast.

I plan to record this show, but would certainly appreciate other recordings as well to add to the archive. On that note, a few of you have sent recordings of the original broadcast (thank you!)–I will post those as soon as I’ve caught up with work, post-‘Fest!

Sproutie hears the Shortwave Shindig

IMG_7321SWLing Post reader, Dave Richards (AA7EE), made a short video of his regen receiver “Sproutie” tuned to the Shortwave Shindig Friday evening.

Dave writes:

“I was quite pleased with the fidelity. Of course, the skirts on a regen are quite broad, even though the nose of the selectivity curve is fairly narrow.  The signal was a bit lower in level and noisier at the beginning of the show but by the time it got to this segment, it was a nice strong signal. Sorry – no S-meter here, so that is the best I can do!”

Dave, thanks for sharing this video! Sproutie did a brilliant job tuning in a program from across the continent. I’m also most impressed with Sproutie’s audio. Amazing!

A Photo Tour of the National Capital Radio and Television Museum

On Tuesday afternoon, I made a pilgrimage the to the National Capital Radio and Television Museum in Bowie, Maryland, USA.  The museum is located in a modest and beautiful historic house on the corner of Mt. Oak and Mitchellville Roads in Bowie.

Museum Curator and volunteer, Brian Belanger, kindly gave me a private tour of the museum collections (the museum is closed on Tuesdays). Brian

Many thanks to Brian for taking time out of his day for the tour, and for allowing me to take some photos for the SWLing Post!

The museum has a number of display rooms with radios broadly grouped by style and decade. The first room offers examples of some of the earliest radios produced–including the venerable crystal radio (below).

Like Brian, numerous volunteers work to keep the collections in working order. This isn’t a place where vintage radios come to die; they actually come to life here.

Speakers of the day were pretty amazing, too–check out this hand-painted 1927 Air Chrome Double Cone Speaker, below.

The museum also has an extensive collection of studio and off-air recordings that can be played over an AM carrier throughout the building.

By the late 1920s and early 1930s, radio manufactures built gorgeous console radios, features in the living rooms and parlors of many lucky homes.

This E.H. Scott All-Wave 23 console (above and below) sported not only twenty-threee vacuum tubes, but a large, robust internal speaker. Radio collectors consider the All-Wave 23 to be one of the finest performing radios of the vacuum-tube era. Scott-Console-Radio-Dial

Zenith-Shuttle

The museum also features the Zenith 12-S-232 tabletop radio with working shuttle dial–a futuristic band-switching mechanical wonder with a stunning dial.

A number of tabletop and portable radios that span the decades have found their homes in this museum.  No doubt many SWLing Post readers cut their teeth on these classics!

I love the design of the Garod Model 5A2–wow! And I’m sure many kids of the fifties wished they had an official Hopalong Cassidy AM radio (below).HopAlongCassidy-Radio

The museum, of course, also houses a large number of classic televisions.

Blinq sale: Sony ICF-SW7600GR $89.39 shipped

Sony-ICF-SW7600GR-RA-CO

The online retailer, Blinq.com, has posted a number of used Sony ICF-SW7600GR radios for $89.39 US, shipped. This is an excellent price for the ‘7600GR–even used.

As I’ve mentioned a number of times, the ICF-SW7600GR is one of my favorite shortwave portables. Click here to read a review that compares the Sony with three other benchmark portables.

Blinq states that the ‘7600GR is fully functional, but may show minor wear (scratches, etc), may come repackaged, but comes with a 90-day warranty.

Though I received a faulty radio from Blinq once, their return process was so effortless and efficient, I personally don’t mind taking my chances. I believe you can buy from Blinq with confidence.

Note that Blinq is also selling the Sony ICF-SW7600GR via Amazon for the same price–click here and search the “used” offer list to view.

Reception of the Shortwave Shindig

ShindigLogoWhiteThanks to so many of you who tweeted, commented and sent messages with live reception reports of the Shortwave Shindig! Despite a little technical difficulty with our Internet connection, which dropped the audio stream to WRMI for a few minutes, the show was quite a success.

And many thanks to SWLing Post reader, Chris Freitas, in Memphis, Tennessee, who writes:

This is audio from Shortwave Shindig at 9 pm Central time at the SWL Winterfest at Plymouth Meeting, PA on 2/27/15. It was transmitted via WRMI on 7570 khz & received in Memphis on Tecsun PL-660. As you can hear, it came in very well.

Reception reports from the east coast of the US, all the way to west coast were most positive. It’s amazing how well WRMI covers the continent.

Speaking of WRMI, we would like to extend a big thanks to Jeff White for extending the Shindig air time–what a great fellow you are, Jeff!
