Tropical Band DXing at home with Elad FDM DUO and Wellbrook ALA1530 active loop

2-jungleRecently I have spent a little more time listening out for Tropical Band stations from my shack in Oxford UK, attempting to emulate some of the very nice signals I have previously recorded out on DX’peditions. The obvious problems with this (and they are numerous) include the relatively weak signal strength of many tropical band stations, the ubiquitous blanket of QRM, resulting in generally poor SNR, lack of space for a large antenna……need I go on?! Fortunately, the Elad FDM DUO has proven to be a very senstive and selective receiver, capable of, at times, incredible SNR, coupled with almost limitless signal conditioning options and SSB, SYNC, ECSS etc. Throw the Wellbrook ALA1530 active loop into the mix (not literally!) and you have a very powerful Tropical Band receive set-up. The Wellbrook is able to null most (although not all) QRM in my shack and that really can make the difference between simply observing a carrier and actually hearing audio. Clearly one cannot expect to hear DX at home under heavy QRM as well as you might outdoors, however, the following stations were logged in the past month or so, with respectable signals, with the ALA1530 indoors:

John takes the Elecraft KX2 on the shortwaves

I just noticed that John (AE5X) has updated the firmware on his KX2 and made a short video of a shortwave band scan. On his blog, he notes:

Before getting my ham ticket, I was a SWL and am very happy that AM capability has been added to the KX2, making a fantastic radio even better.

[…]We have a very powerful AM broadcast station near my QTH on 740 kHz. I was not able to receive it at all with the KX2. Unlike some, I see this as beneficial – it tells me the 80m filters (the KX2 doesn’t operate on 160m) are doing what they were designed to do.[…]

Update: I’ve had my KX2 for 24 hours now! I’ve already updated the firmware and will post a couple AM audio samples soon.

Radio Fana 6110 kHz Ethiopia; excellent SNR with Elad FDM DUO

FanazaThe Elad FDM DUO makes for a fantastic receiver, in both standalone mode and via the FDM-SW2 software. Thus far it has been demonstrating this by outperforming the Sony ICF-2001D in many of my reception tests using an experimental longwire antenna. Bear in mind that whilst this might not be such a surprise, the Elad without the FDM-SW2 software driving it has no SYNC, which is often invaluable for Tropical Band DXing. To make the point further, here is a wonderfully clear signal from Ethiopia, with, in my experience at least, exceptional signal-to-noise.

My 200 metre longwire is still very much a work in progress. I am in the process of building a termination resistance box, receiver-end termination suitable for high and low impedance inputs and earthing straps for metre-long copper pipes that will remain in-situ. When I have completed these tasks, I will record a video because I know some of you are interested in the details. For now though, it just remains an experiment – 200 metres of wire and very late nights/ early mornings!  Recorded at the ‘DX woods’ in Oxford UK at 03:23 hrs UTC on 31/07/16. Thanks for watching.

Reminder: The Classics Experience with Paul Walker

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.

Latest Update regarding Radio Australia outage

Many thanks to SWLing Post contributor, David Goren, who shares this latest update from ABC Reception advice:

Thank you for your email.

We are working towards restoring the services this coming Friday at 9am Sydney time.

Kind Regards,

ABC Reception Advice

A number of Post readers received this same message (thanks to you all for sharing).  I, for one, hope to hear my staple broadcaster back on the air Friday morning.  I’ll certainly be listening!
