DX’pedition: first test of deployable 200 metre longwire antenna by Oxford Shortwave Log

A view looking toward  Oxford Shortwave Log DX’pedition territory; a wood in rural Oxfordshire

Regular viewers of my youtube channel will know that I spend much of my shortwave listening time out in an Oxfordshire wood where QRM is negligable and Tropical Band stations can be heard with, at times, unprecidented signal-to-noise. Regular viewers will also be aware that I enjoy experimenting with different antenna set-ups, particularly pushing the boundaries with longwires coupled to portables. Having applied my rather modest practical skills, I constructed a 200 metre deployable 200 metre longwire antenna and finally got around to testing it, with my Elad FDM DUO and Sony ICF-2001D. There are a number of reception videos still to be uploaded to the Oxford Shortwave Log youtube channel, howvever, the immediate information and entertainment of SWLing Post readers, I have included two here. 🙂

The first is the more commonly heard Emisoras Pio XII from Boliva on 5952.5 kHz using the Sony and the second, the much more rarely reported Radio Chaski from Peru on 5979.9 kHz using the Elad. Both reception videos were very encouraging. In fact, I would go so far as to say they demonstrated excellent reception witihin the framework of their respective contexts. Emisoras Pio XII was almost booming with unprecidented signal strength and clarity, whilst Radio Chaski was heard with discernible audio. Neither station had been received as well at my QTH or the woods, previously.

I hope this gives other DXers ‘food for thought’ with regard to experimenting with antennas and perhaps more importantly, making significant improvements to SNR by removing themselves from the ubiquitous blanket of QRM generated by all of those devices at home that are intrinsic to modern life. Thanks for watching. 73.

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

Earth

(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.

The Classics Experience with Paul Walker: August 26 and 27

SX-99-Dial-Nar

Many thanks to SWLing Post contributor, Paul Walker, who announces his next show:

The next broadcast of The Classics Experience with Paul Walker is going to be the biggest yet. It’ll all take place in late August with 2 hours of rock n roll music with maybe a few country songs thrown in for good measure. The show is ALL about the music and providing something different on the shortwave bands, so all you’ll get from the show is MUSIC. There will be NO rants, raves, personal opinions or political and religious rants. No commercials or sponsors either. I fund the broadcast out of my own pocket so I can pick whatever music I want and not have to answer to anyone but George D. Beagle!

WRMI 7570kHz Saturday August 27th 0400 to 0600UTC. Beaming at 315 degrees towards Vancouver. It should provide a good signal to the West Coast of the US and Canada and probably parts of the midwest and upper midwest along the way.

WRMI 11580kHz Friday August 26th 2100 UTC to 2300UTC., This signal target area is Eastern North America and Western Europe.

WRMI 11530kHz Saturday August 27th, 0200UTC to 0400UTC targetting South America with maybe a little spill over to extreme Western Africa.

WINB 9265kHz Saturday August 27th 0330 to 0530UTC. This should provide good coverage into the Midwest, parts of southern Canada, into Mexico along with parts of Central & Southern Europe it seemed.. It was weakly heard in Australia and New Zealand during my last broadcast.

Channel 292 6070kHz Friday August 26th 2200 to 2400UTC. This should provide good coverage of central and parts of Western Europe.

Shortwave Services 15195khz via Armenia Saturday August 27th 1200 to 1400UTC. Beaming at 65 degrees towards Japan.

I am going to suspend my request for $ to cover postage and QSL costs. I’ve been so lax in sending out QSL cards, I haven’t gotten around to any of them from previous broadcasts and have gotten a few nastygrams about it. I feel bad, so I won’t ask for any money to cover costs this time around.

Contact information for reception reports:
Paul B. Walker, Jr.
PO Box 353
Galena, Alaska 99741-0353 USA

There may be MFSK32 data and pictures during the broadcast. I will announce during the broadcast if and when that happens.
