The GP5/SSB receiver I got as prize from your SWLIing Post Virtual Radio Challenge is great. My friends envy the cute Monster 🙂
Well with this radio I am monitoring 40m and 20m HAM bands regularly. Since January till date I have received several stations. Most interesting stations till date are VK6HCF/portable, RW9JZ and EA3JE (from India).
Here’s a screen shot of the log book if you like to see. 🙂
This is excellent news, Ashok! Many thanks again to CountyComm who sponsored our Virtual Radio Challenge IV.
I hope to have another sponsored challenge posted within the next month or two. Frankly, I have multiple projects on my table, so free time has been almost non-existent the past few weeks. Indeed, I’m still catching up on a back log of correspondence I received during my travels last month! (I appreciate your patience and understanding!)
Happy listening, Ashok!

Many thanks to SWLing Post reader, Danny Garris (KJ4FH), for the following guest post which originally appeared on his blog, Up In This Brain:
How I cleaned the sticky coating off of my Grundig G6 radio with guidance from KJ4FH
A few weeks ago, I reached out to Danny Garris, KJ4FH, for help on getting the sticky coating off of my Eton E5 radio. I noticed on eBay that he was selling Eton radios with the gunk cleaned off and I was wondering how he did it.
Where does the sticky gunk come from? Well, for some reason the “geniuses” up at Eton/Grundig put a rubberized, chemical coating on a series of radios they released. They looked great new but over time, them coating seems to get adhesive-like properties, almost like it is melting off. It apparently has something to do with humidity and over time it makes everything stick to the radios – dust, dirt, you name it. It’s terribly annoying and just plain nasty. Shame on Eton/Grundig for doing this because a whole generation of good radios are impacted.
This leads me back to Danny and the instructions I have posted below in my Dropbox with his permission.
I used rubbing alcohol at first on my Eton E5 based on some back and forth emails I had with Danny and it did remove a ton of the gunk but I also ended up with places in the finish where the paint was removed, as he warned. Still, my concern was getting rid of the gunk more than appearances since my Eton E5 is a radio I use almost daily that I have no intention of selling. In fact, I am keeping an eye on eBay for a spare unit to purchase just in case because the E5(also Grundig G5) is an amazing radio.
Not long after getting his full instructions with oven cleaner as a new ingredient to try, I noticed a Grundig G6 for sale on eBay for just $19.99 as a buy it now price. I briefly had a G6 years ago and I have always missed it but good units are typically somewhat expensive and rare. This G6 was advertised as working perfectly but completely sticky. The seller posted pictures showing it was one of the stickiest and nastiest radios I had ever seen. But, armed with Danny’s method for cleaning the radios, I grabbed it, knowing I probably would not get another chance at a G6 for such a cheap price.
Below are before and after pictures. The before pictures are from the eBay auction and the radio did in fact arrive that nasty but it does work perfectly! In fact, it is a fantastic performer for the size. I love the tuning knob and the tuning method alone makes it much easier and more fun to use than my Tecsun radios and my recently purchased Eton Traveller III. The G6 is a worthy companion for my Eton E5 and I am very pleased with this purchase.
The after pictures are from the hour of work I did cleaning the radio last night. So far I have cleaned the radio with oven cleaner only. I took about 45 minutes using the Q-tip method and then about 15 minutes “polishing” with a clean white cloth dipped in oven cleaner as I went. I still have some additional detail cleaning to do but the results so far are like night and day.
I owe Danny a big thank you as you can see in the images below and, keep in mind, I still have a bit more work to do so this radio is going to look even better shortly!
Here is the front as shown in the auction. Gross! According to the description, the seller bought it at an estate sale.
What a difference some over cleaner makes! I need to blow out the speaker with compressed air to get the Q-tip remnants out and do some minor detail work but the front is almost in new condition now.
As shown in the auction listing, yuk!
I may do a little work with rubbing alcohol or WD-40 to get the shine back on this side but wow – what a difference!
I wonder if this radio was laying in the grass or something. It was nasty to even pick up and touch!
After oven cleaner, it’s like new again. I need to do a little more detail work but that’s it!
This picture in the auction made me wonder if I was biting off a bit more than I could chew!
I still have a bit of work to do on the back but WOW! What a difference!
What a difference, indeed! Thanks for sharing your experience and results, Danny!
I love my little Grundig G6 and, for some reason, the coating has yet to become properly sticky. I know it’s only a matter of time, though, so I’ll keep this procedure in mind.
This has actually been a fairly popular topic on the SWLing Post, no doubt because so many SWLs have radios with tacky coatings. Click here to read previous posts with cleaning techniques.
If you’re interested in the now discontinued Grundig G6, check eBay for listings. Perhaps you too can find a “sticky” radio special!
Interest in shortwave numbers stations seems to wax and wane. We’re currently going through a period of increased interest (again) as I’ve been receiving quite a few messages from new readers asking where to find spy numbers and what type of shortwave radio is needed. Truth is, there are fewer and fewer numbers stations still on the air, though some are still quite reliable (like HM01).
The following article by Shane Harris at The Daily Beast is one of the better, more detailed, articles I’ve read in the popular press.

The Stupidly Simple Spy Messages No Computer Could Decode
by Shane Harris
When I was 10 years old, I found a shortwave radio in a crumbling old leather trunk where we kept family photos and other memorabilia.
As I spun the dial, tinny, modulating noises, like the song of an electronic slide whistle, emanated from the radio’s small speaker. Staticky cracks and pops competed for airtime. The sounds swished and swirled, unintelligible and unremarkable. But then, emerging through the clamor, was a voice.
I might have run right over it with the dial, but the voice’s rhythmic, steady pacing caught me up short. It wasn’t a deejay. Nor a commercial. And he wasn’t singing. He was just speaking. The same line, over and over again.
“7…6…7…4…3.” Pause. “7…6…7…4…3.”
I don’t remember if those were the exact numbers. But they were numbers. A repeated sequence which had no obvious meaning, and was entirely devoid of context. To find him here, amidst the screeches and howls of the shortwave frequencies, was like coming upon a man standing in the middle of a forest, talking out loud to no one.
How long had he been here? Who was he talking to? He had that officious tone of the recorded telephone operators who chastised you for dialing a wrong number. “Please hang up, check the number, and dial again.” And the same distracting static I’d heard in those messages filled the background. I wasn’t sure if he was speaking live, or if he’d been recorded and set loose to play into the air.
But there was an urgency to his tone. And a purpose. As if he were talking to me. Imploring. Listen. Hear me now. 7…6…7…4…3. Did you get that? 7…6…7…4…3.
I was simultaneously terrified and captivated.[…]

Shortwave Radio 1974: Canada, Argentina, Spain, West Germany, Albania, utility stations
Want to know what shortwave radio sounded like in 1974?
This 55-minute recording, recovered from a cassette, was never intended to be anything but “audio notes”: I was an 18-year-old shortwave listener who collected QSL cards from international stations, and I was tired of using a pen and a notepad to copy down details of the broadcasts. I wanted an easier way to record what I heard, and my cassette tape recorder seemed like the perfect means to accomplish that goal.
But it wasn’t. I soon discovered that it was simpler to just edit my notes as I was jotting them down — not spend time on endless searches for specific information located all over the tape. To make a long story shorter, I abandoned my “audio notes” plan after a single shortwave recording: This one.
Hallicrafters S-108 (Image: DXing.com)
Still, for those who want to experience the feel of sitting at a shortwave radio in the mid-1970s and slowly spinning the dial, this tape delivers. Nothing great in terms of sound quality; I was using a Hallicrafters S-108 that was outdated even at the time. And my recording “technique” involved placing the cassette microphone next to the radio speaker.
Thus, what you’ll hear is a grab bag of randomness: Major shortwave broadcasting stations from Canada, Argentina, Spain, Germany and Albania; maritime CW and other utility stations; and even a one-sided conversation involving a mobile phone, apparently located at sea. There are lengthy (even boring) programs, theme songs and interval signals, and brief IDs, one in Morse code from an Italian Navy station and another from a Department of Energy station used to track shipments of nuclear materials. And I can’t even identify the station behind every recording, including several Spanish broadcasts (I don’t speak the language) and an interview in English with a UFO book author.
The following is a guide, with approximate Windows Media Player starting times, of the signals on this recording. (Incidentally, the CBC recording was from July 11, 1974 — a date I deduced by researching the Major League Baseball scores of the previous day.)
Guide to the Recording
0:00 — CBC (Radio Canada) Northern and Armed Forces Service: News and sports.
7:51 — RAE (Radio Argentina): Sign-off with closing theme
9:14 — Department of Energy station in Belton, Missouri: “This is KRF-265 clear.”
9:17 — Interval signal: Radio Spain.
9:40 — New York Radio, WSY-70 (aviation weather broadcast)
10:22 — Unidentified station (Spanish?): Music.
10:51— Unidentified station (English): Historic drama with mention of Vice President John Adams, plus bell-heavy closing theme.
14:12 — RAI (Italy), male announcer, poor signal strength.
14:20 — Unidentified station (Spanish): Theme music and apparent ID, good signal strength.
15:16 — Unidentified station (foreign-speaking, possibly Spanish): Song, “Chirpy Chirpy Cheep Cheep.”
17:00 — Deutsche Welle (The Voice of West Germany): Announcement of frequencies, theme song.
17:39 — Unidentified station (English): Interview with the Rev. Barry Downing, author of “The Bible and Flying Saucers.”
24:36 — One side of mobile telephone conversation in SSB, possibly from maritime location.
30:37 — Radio Tirana (Albania): Lengthy economic and geopolitical talk (female announcer); bad audio. Theme and ID at 36:23, sign-off at 55:03.
55:11 — Italian Navy, Rome: “VVV IDR3 (and long tone)” in Morse code.

I just received the following notification on The Mighty KBC’s Facebook page:
Due to the lack of new sponsors,
The Mighty KBC will close down on 6095 on March 27th.
We will soon announce if we continue on shortwave on 6040 to the USA.
We will improve our 1602AM /DAB+ service.
This will happen on April 1st.

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!
