Many thanks to SWLing Post reader, Rick Slobodian, who writes to request help with the following:

I was on the beach at our lake, [where I was listening to my] Tecsun PL-606 receiver.

[On Friday, August 19, 2016 at 1800 UTC, I noted a] “beeper”: beeps at Hz repetition rate , does not appear to be data, it beeps for about a minute then there is a short data burst then beeping again for a minute or two.

This went on for over an hour.

Location of Vernon, British Columbia, Canada (click to enlarge).

[The beeping covered] all frequencies between 13400-13800 kHz. [Then on August 20, it started at] start 1745 UTC and was no longer on 3400-13800 but now on
all frequencies between 12120 -12250.

What is it? [Take a listen:]

My ham radio friend says there are a network of stations that send out pings that everyone in the group transmits and everyone receives. The signal strength and phase of the rx signal is correlated at each receiver station, to direction find some unknown station.

Was there such a thing during the cold war, and is it still around? What is this system and where can I find out more about it?

Thanks for your inquiry, Rick. This is outside the scope of what I understand on the HF bands, so I hope SWLing Post readers can chime in and offer suggestions.

Please comment if you can help Rick ID this transmission!

Dan offers services to digitally preserve off-air recordings on legacy formats

Many thanks to SWLing Post contributor, Dan Robinson, who writes:

Some years ago, I urged those of us survivors in the shortwave listening community to transfer any reel or cassette tapes to digital format. In recent years we have lost many top DX’ers to illness. Collections of recordings have unfortunately also been lost because family members are not able to preserve them or have no interest in doing so.

If any SWLing Post readers have such recordings, I am able to transfer them from/to to any format — including MD, SONY Microcassette (both of these are obviously still legacy formats but many still use MD for example), and straight to solid state media such as SD, MicroSD, etc

While I realize that most people do have the knowledge and capabilities to transfer old recordings, I know many lack the time and patience to do so. So I am offering my services here, for reasonable fees to compensate for time invested. You can reach me at: [email protected]

Those who wish to simply donate recordings can send them to me (please get in touch first). Anyone who does wish to have their recording collection(s) transferred in full and to have original tapes or cassettes returned, I ask to be compensated for postage costs. If you wish to provide solid state media for the transfers that is fine, but please make sure that thumb drives or memory cards are of sufficient size. Otherwise I will obtain memory cards/sticks and add this to the cost.

In recent years I have transferred recordings of about a dozen DX’ers who have passed, and for a few who left the hobby. All of these recordings are valuable as they represent snapshots of the SW broadcasting era and of history — they should be preserved.

I can certainly vouch for Dan and his integrity, so if you would like to have your recordings transferred, he’s the guy to do it. Thanks, Dan!

Gospell announces the imminent release of GR-216 DRM/AM/FM digital radio

Chengdu, China, September 05, 2016

Gospell, a leading supplier of pay TV system and equipment, satellite TV receiving products and microwave products, is delighted to announce the imminent release of GR-216 DRM/AM/FM digital radio, the first model in its Global Radio series range of tabletop radio. The product is designed to meet the demands of easy access to high quality information for cost-sensitive market at an affordable price.
GR-216 is equipped to receive DRM broadcast, as well as traditional FM with RDS and AM in medium wave band and shortwave band. Featuring a high performance DRM/AM/FM tuner, GR-216 provides noise-free reception of even the weakest stations. It supports the latest audio compression standard xHE-AAC and traditional HE-AAC as well as SBR and parametric stereo.
Besides the built-in whip antenna and ferrite bar antenna, dedicated AM/FM external antenna terminals with switch are located on the rear side of the radio, this will help those who live or work in a metal or concrete building and enjoy listening to a radio.
This unique radio will automatically turn itself on and initiate its emergency-tuning process when the Emergency Warning Broadcasting is engaged. The radio will enlarge its volume, flash the backlight, play siren sound and tune itself to the emergency program.
In addition to DRM program recording, AM/FM are also supported. Recorded program will be stored on the attached USB pen drive and can be played back on other devices such as a phone or a tablet. The GR216 also includes a scheduler which allows the user to schedule regular and unattended recordings for their favorite radio programme.
The built-in high-quality 3 inch full-range speaker with enlarged magnet provides outstanding audio performance and room filling sound. With the help of state-of-the-art audio processing technology, GR-216 includes separate bass, mid and treble tone controls and a graphics equalizer, users can tailor the sound to their taste. We’ve provided an output for headphones along with an audio output on the rear side of the radio for line recording or to connect GR-216 as a radio tuner to a home audio system.
As a tabletop radio, GR-216 features dual independent alarm clocks with sleep timer. The alarm clock allows for once, daily, weekday and weekend settings. The alarm can be adjusted to the volume you prefer with buzzer or radio stations.
All aspects of set-up, time and program information are clearly shown through an easy to read large LCD display with white backlight, which is paired with an intuitive rotary control, enabling quick and easy navigation.

Dave repairs a Sony ICF-6500W

6 Replies

Many thanks to SWLing Post contributor, Dave Zantow, who noticed my comments about the Sony ICF-6500W in the Shelby Hamfest photos and replies:

Speaking of the Sony ICF-6500W, I just brought one back from the dead. Have a few comments I just added to the bottom of my Sony page.

http://webpages.charter.net/n9ewo2/sony.html

The good old long band selector switches were extremely dirty in my case (it has 2). Not sure if the 6500W has the nasty “well known” bug that plagues ALL similar designed Panasonic sets from that era (RF- 2600 / 2800 / 2900 / 4800 / 4900 etc..) , where those switches TOTALLY fail in time. In the case of this Sony it was just the extremely dirty switches (at least for now).

Very cool, Dave. Honestly, I don’t think I had ever seen the ICF-6500W in person until Saturday. The seller had noted that the pots were “scratchy.” I suspect it needed some healthy, strategic doses of DeOxit!

Thanks for sharing your experience!

AIR to recruit Balochi speakers with money saved from shortwave broadcasts

All India Radio (AIR) Headquarters in Dehli, India. Photo courtesy of Wikipedia.

Many thanks to SWLing Post contributor, Mike Barraclough, who shares the following link from The Sunday Guardian Live via Facebook:

At present, AIR has only two Balochi speaking people who have been helping with the daily one-hour programme transmitted to Balochistan. A senior AIR official, on the condition of anonymity, said, “There has always been a dearth of Balochi speaking people here. Even before Balochistan got attention in mainstream Indian media, we had been working to improve our Balochi show. For years, we had been writing to the Ministry of Home Affairs and Ministry of External Affairs to help us get some talented people from Balochistan who can work with us on improving content in our Balochi shows. ”

[…]”Since we are gradually switching from short-wave to a web-based service now, all our overseas shows in various languages are already starting to get more human resource. We have more funds to invest on quality of our programmes. Earlier, such funds were largely spent on the maintenance of short-wave machinery.”[…]

A photo tour of the 2016 Shelby Hamfest

IMG_20160903_093439923

My Labor Day weekend was free of travel again this year, so I was able to make another pilgrimage to the Shelby (North Carolina) hamfest with my good buddies, Vlado (N3CZ), Dave (K4SV) and Phil (W9IXX). This year, all four of us brought things to sell in the flea market.

The Shelby Hamfest–referred to, locally, as “The Grand-Daddy of them All”–has long been regarded as one of the largest hamfests in the southeast US. Last year, I posted photos from the hamfest and many of you sent notes of thanks for that.

We arrived very early yesterday, prior to the gates opening for general admission. We set up our tables and almost immediately had customers in front of us. This year, I was in selling mode, not buying mode, as I desperately need to downsize some of my collection and use the money to offset costs of review radios, and some of the conferences I’m attending this year.

The seller of this Grundig Satellit 500 only wanted $75–an exceptional bargain. I turned it on, though, and quickly discovered the LCD screen worked intermittently after having only been on for a few seconds. It was a little scuffed up too. Still–it produced great audio.

Someone had done a spectacular job restoring this Super-Pro. It would make a fine addition to any shack.

The same seller who had the Grundig Satellit 500 was also selling this Sony ICF-6500W for $75. Other than scratchy pots, it seemed to work well. It was very tempting to purchase, but I passed in the end. IMG_20160903_093525866_TOP

He was selling this Panasonic for $150. I passed because I had a hunch it needed a little work.

One of the finest R-274-As I’ve ever seen. Again: someone spent a great deal of time restoring this beauty. By the time I found it in the flea market, it had already been sold. Thank goodness!

I must have spotted at least six or seven Hallicrafters SX-100s this year at Shelby.

I managed to come home with only $40 worth of parts: connectors, cables, plugs and a 17 meter band MFJ whip antenna (to try on my recently-acquired Elecraft KX2). I was pretty proud of myself as there were an exceptional number of vintage radios I would have loved to have taken home (like the console radio below–!).

NPOTA activation on the Blue Ridge Parkway

3 Replies

A crowd gathers as Vlado (N3CZ) works station after station in CW!

I’m not sure what I’m going to do after the National Parks On The Air event is over at the end of this year. I hope the ARRL organizes something equally as fun for 2017.

Truth is, I love playing radio outdoors and I love National Parks. The two are a perfect combo.

Vlado (N3CZ) on left, and me (K4SWL) on right.

My buddy, Vlado (N3CZ), and I decided to do an NPOTA activation on Sunday. The weather was fantastic–a little foggy with mild temperatures and the HF bands were open!

We arrived at our site–the Craggy Gardens Picnic Area (PK01)–at 14:30 UTC or so.

We brought the following antennas and supports:

a self-contained 20 meter band telescopic fiberglass vertical (I recently purchased at the WCARS Hamfest for $40–!) and
a 31 foot fiberglass Jackite pole (the fluorescent orange on in the photos) which we used to suspend a homemade 40 meter doublet Vlado built the day before.

Setup was quick. We were both especially pleased the 20 meter vertical. It was so easy to install, even considering it was the first time either of us had used it.

I powered the LD-11 and the KX3 with my QRP Ranger.

The 20 meter vertical antenna (in foreground).

I operated SSB from a picnic table using the LnR Precision LD-11 transceiver, connected to the doublet on 40 meters, and the mono-band vertical on 20 meters.

Vlado started by operating CW with his Icom IC-7000 which was installed in his car, but later moved to the picnic table and logged a number of contacts with the Elecraft KX3.

We easily logged the number of stations needed to activate the site.

The 40 meter band was hopping and a good path was open into Ohio, Virginia and other surrounding states. The 20 meter band was serving up some excellent QRP DX.

Vlado operating CW on the 40 meter band.

When I moved to the 20 meter band, the noise floor was so low on the LD-11, I thought perhaps the band was dead. Not so!

It’s hard to believe that with a mere eight watts in SSB I worked Rhode Island, Texas, Montana, Manitoba, Washington, California and Slovenia from a picnic table on the Blue Ridge Parkway.

Reports on the LD-11 audio were all very positive. I’ve used the LD-11 for eight NPOTA activations this year and can say with confidence that it’s a brilliant & fun little field radio. (FYI: I’ll be publishing a full review of the LD-11 in the October 2016 issue of The Spectrum Monitor magazine.)

Vlado and I are planning on several more activations together this year. Our next one will most likely be at the Carl Sandburg Home-. I can’t wait!

Any other post readers participating as an activator or chaser in the National Parks on the Air event?
