Let the conspiracy theories resume! Alaska’s High-Frequency Active Auroral Research Program (HAARP) facility will reopen in 2017. The sprawling facility now is under the ownership of the University of Alaska Fairbanks (UAF), and the UAF Geophysical Institute is preparing HAARP for a new sponsored research campaign that’s set to begin early next year, UAF Researcher Chris Fallen, KL3WX, told ARRL.

“This involves, for example, reinstalling the vacuum tubes in each of the 10 kW amplifiers — eventually 360 in total — that were removed by the US Air Force [the facility’s former owner] for warm storage in the main facility,” Fallen said. He later clarified that’s just one-half of the 720 tubes required to equip all of HAARP’s transmitters. “For the first campaign we will only be bringing half of the array online, as we will only have half the tubes installed,” he explained. “It’s a long process and we have limited resources.” He noted that the transmitter shelters have been unheated since the previous campaign in the summer of 2014. “The five generators — approximately 3 MW each — have recently been tested individually and are verified operational.”

The Sony ICF-5500W: My morning companion

8 Replies

I spent this morning doing a lot of work around our property. When it was time for a break, I turned on my trust Sony ICF-5500W and tuned to WTZQ: one of my favorite regional AM braodcasters. Though WTZQ is over 30 miles from my home, any good AM radio, like the ICF-5500W, can receive their 1,000 watt signal with ease.

As luck would have it, when I turned on my 5500W, WTZQ started playing Love Me Do by The Beatles. It sounded absolutely amazing via the 5500W’s internal speaker: full-on, rich AM audio fidelity! Absolutely brilliant!

I cranked up the volume so our local black bears could enjoy.

I relaxed a good half hour, and caught up on reading the latest two issues of RadCom with my ICF-5500W playing WTZQ in the background.

Sometimes it’s the simple stuff that starts one’s morning off the right way.

That and plenty of good coffee.

Radio Australia off the air this week

Many thanks to SWLing Post contributor, Mike Nikolich (N9OVQ), who writes:

Radio Australia has been off the air all week. My buddy Ron Howard in California contacted reception.advice@abc.net.au regarding this issue, and received this response:

“Thank you for your recent correspondence with regards to the Radio Australia Broadcasts on Shortwave Radio in the SW Pacific. We are currently working with our transmission provider on a number of shut downs over the past week and again over the next week to investigate a range of technical and commercial issues for the service.

In the meantime the services are still on air via our satellite services on Intelsat IS18 and IS22 as well as our FM network across the targeted markets in the SW Pacific (for detailed information please see http://goo.gl/2Y7xS3 ) and of course Radio Australia is online at http://www.radioaustralia.net.au/listen.

Thank you also for your audio clip of ABC Alice Springs NT!

Kind Regards,

ABC Reception Advice (Communications Networks)”

Tom, you have more than 10,000 people regularly following your blog. Can you encourage your readers to contact Radio Australia and tell them how important their shortwave transmissions are to them? I have been listening to this station continuously since 1972 and I would be crushed if they left the air. I begin most mornings by listening to their loud, clear English language shortwave signal on 9,580 kHz.

Thanks, Mike. Like many other SWLs, I too have noted that Radio Australia has been off the air this week. Without a doubt, Radio Australia is my staple source of news on shortwave these days and a part of my morning ritual (cup of coffee and RA–!).

I will send them an email immediately.

Post readers: if you enjoy Radio Australia, please take Mike’s advice and contact them at your earliest convenience.

BHI Summer Sale

Many thanks to SWLing Post reader, TomL, who notes:

Not sure if you had anything posted for this but I stumbled on BHI having a summer sale until August 16. So, I went onto YouTube and listened to a number of user demos and chose to buy the Compact Inline model. So, I get 10% off using the special code plus the British Pound has gone down against the US Dollar over the last few months by about 15% or more. Shipping is a bit more expensive but overall seems worth it. Just thought I would pass it along!

TomL from noisy Illinois

Thank you, Tom! I know DX Engineering also stocks BHI products here in the States, but I imagine with the currency conversion and summer sale, it might even be less expensive to order directly from BHI.

I hope you report back and let us know how well the Compact Inline filter works for you!

Bruce believes the CC Skywave is an ideal travel radio

The C.Crane CC Skywave

Many thanks to SWLing Post reader, Bruce Atchison, who recently shared his positive comments about the CC Skywave. Bruce writes::

This is a lot of radio for such a small size. The CC Skywave is a great travel companion because of its portability and price.

Moreover, it’s rich with features. The receiver tunes in AM and FM as well as all the shortwave bands, NOAA weather channels, and the aircraft band. The latter comes in handy while you’re waiting for flights so you can find out immediately and directly what is delaying them.

It also has a built-in alarm clock so you needn’t miss the next morning’s activities.

The Skywave runs on 2 AA cells and can be set to charge NiMH rechargeable batteries. Its mini-USB port lets you use the AC adaptor or 12 volt cigarette lighter adapter. You can even use one of those cell phone solar panels to power the set.

This radio’s reception is excellent and its filters allow for eliminating adjacent channel interference. Apart from its rather high noise floor on AM, the receiver pulls in stations at night very well.

The Skywave can also add local stations to its memory pages automatically. This comes in handy in foreign cities when you don’t have time to manually scan the AM and FM dial.

This is truly a globe trotter’s accessory. You can set it to European AM channel spacing and the Japanese FM band. The radio even has a fine tuning setting for oddly-spaced stations.

The three amber LEDs light up the dial nicely and they turn off automatically after about ten seconds to conserve battery life. In fact, the Skywave is amazingly energy efficient.

Whenever I travel, this radio is one thing I’ll be sure to pack. It’s all I need when I travel away from home.

Thanks for sharing your thoughts, Bruce. Yes, I believe the Skywave is a great little travel radio, too. One of the Skywave features I used extensively while off-grid in Canada this summer, was the weather radio function (Environment Canada and NOAA frequencies are the same). Without Internet, it was an excellent, handy source of weather information.

WRMI to showcase digital modes via analog radio

WRMI, Radio Miami International, will showcase digital text and images via analog radio in a half-hour special broadcast to be transmitted nine times (at least), beginning Saturday, 13 August.

The broadcast will mostly be in MFSK32 centered on 1500 Hz. There will also be segments in MFSK64, MFSK32 centered on 2200 Hz, and Olivia 64-2000. The program will include MFSK images, examples of non-Latin alphabets, and an Flmsg transmission. You will also hear “co-channel” music.

To decode the modes on the WRMI broadcast, Fldigi software is recommended. Download it fromhttps://sourceforge.net/projects/fldigi/files/fldigi/ . The main Fldigi website is http://www.w1hkj.com.

And you will use the companion program Flmsg. Download it fromhttps://sourceforge.net/projects/fldigi/files/flmsg/ .

To make Flmsg work with Fldigi, in Fldigi: Configure > Misc > NBEMS > under Reception of flmsg files, select Open with flmsg and Open in browser, and below that indicate where your Flmsg.exe file is located – probably somewhere in Program Files(x86).

For correct decoding of the languages with diacritics, or using non-Latin alphabets, in Fldigi: Configure > Colors & Fonts > RxTx > in the Rx/Tx Character set menu, select UTF-8.

For Fldigi to automatically select the mode and the center audio frequency of the mode, select RxID (upper right of the interface) by left clicking. In newer versions of Fldigi, also right click on RxID and select Passband.

You can decode this WRMI special broadcast as it is broadcast, or from your recording.

USAF wants to release ionized gas in the upper atmosphere to improve HF

6 Replies

(Source: Southgate ARC)

New Scientist magazine reports the US Air Force is working on plans to improve HF radio propagation by releasing ionised gas in the upper atmosphere using a fleet of micro satellites

As well as increasing the range of radio signals, the USAF says it wants to smooth out the effects of solar winds, which can knock out GPS, and also investigate the possibility of blocking communication from enemy satellites.

The story says there are at least two major challenges. One is building a plasma generator small enough to fit on a CubeSat – roughly 10 centimetres cubed. Then there’s the problem of controlling exactly how the plasma will disperse once it is released.
