The 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.

A strong signal with a clear ID from Conakry, Guinea, heard in Oxford UK on 08/08/16 at 18:04 hrs UTC using my trusty Panasonic RF-B65 and a 50 metre longwire. No SYNC of course, but once again, the vintage Panasonic performs very well for this personal-first reception. I do have another recording of this station using the Sony ICF-2001D, from which a performance comparison can be made at a later date. Great to hear Radio Guinée by the way; I believe they had been off-air for around 5 years, until earlier this year. Click the image below to watch the reception video on Oxford Shortwave log.

As is my typical style, I’ll do some DX’ing for weeks, if not a month or more before I sit down and write out logs. I focus on logging and recording first, then writing reports later as I’m worried i’ll miss something on the dials.
I have a few good ones this time around, like usual. Lets get on with the logs!
There are a few good ones here, including The Voice of Mongolia 12035 kHz, Vivdh Bharati on 9870 kHz and others along with some usuals.
2850 kHz, 3250 kHz & 3320 kHz, The Voice of Korea via Pyongyang to North Korea and the Far East in Korean on August 2, 2016 from 1623 to 1627UTC. The tropical band signals of VoK are somewhat rare and kind of weak during the summer but much more regular and stronger in the winter. This time around, 2850 kHz is the strongest with a woman singing in Korean. The signal is weak but easy to understand despite the noise. 3250 kHz and 3320 kHz both featured a man talking, 3250 had a song shortly after my recording began. 3560 kHz wasn’t heard on this date, but it was heard back on July 23, 2016 at 1502UTC with a pretty weak signal, full of noise, yet music was definately heard above the buzzing!
4885 kHz, Echo of Hope to North Korea in Korean on July 28, 2016 at 1623UTC. Their other frequencies always seem to be jammed but I’ve not heard this Anti North Korean station have it’s 4885 kHz signal jammed. It’s a pretty good signal, clean, clear, fairly steady with only some light fading. Audio here: https://www.youtube.com/watch?v=sgZUOjZaQPE
5020 kHz, Solomon Islands Broadcasting Corporation via Honiara to the Solomon Islands on August 1, 2016 at 0953UTC. The SIBC is here just about nightly and at least very poor levels. The signal on this night with local music is fair but with a good amount of fading and noise. Audio here: https://www.youtube.com/watch?v=A67vQd04Uj0
5857 kHz “HLL Seoul” on July 28, 2016 at 1634UTC. A weather broadcasting station from Seoul, South Korea often with digital data but does have voice from time to time, I’ve heard both but never this clear. The voice isn’t usually this clear or loud. Audio here: https://www.youtube.com/watch?v=a5eICMqMCaQ
7280 kHz, The Voice of Vietnam in Russian via Hanoi to Europe on July 26, 2016 at 1639UTC. A poor signal with lots of fading, static and noise and possibly some interference as well. A man was heard talking in Russian. Audio here: https://www.youtube.com/watch?v=h7nt1J0QGWQ
9390 kHz, Radio Thailand World Service in English via Udon Thani on July 23, 2016 at 1955UTC. Radio Thailand is here from time to time and while it may be strong sometimes, it’s usually a pretty fade-y signal. This signal would be on the high side of fair if it wasn’t for all the noise and fading. The recording starts off with what sounds like ad’s for a business marketed to english speaking ex pats and tourists. A sign off message then airs but the carrier doesn’t drop as far as I can tell before the German service starts at 2000UTC. Audio here: https://soundcloud.com/onairdjpaulwalker/radio-thailand-9390-july-23
9420 kHz, The Voice of Greece via Avlis to Europe. on August 1, 2016 at 2326UTC. The Voice of Greece is not heard here too often and when it is, it’s often a noise, static and fade-y ridden signal like this is with a woman talking, but about what, I don’t know. Audio here: https://www.youtube.com/watch?v=ul6kf5cdvho
9635 kHz, The Voice of Turkey in French via Emirler to Western Europe on July 23, 2016 at 2021UTC. The Voice of Turkey is pretty rare here, I can’t recall it paying a visit very often. The is about as good as I can recall hearing them here Despite the extreme noise, It is still a steady signal with a musical selection, a man talking and then a musical selection before the carrier is turned off. Audio here: https://www.youtube.com/watch?v=MMXlIHiDl7U
9735 kHz, Radio Taiwan International in Japanese via Paochung/Baujong to Japan on July 31, 2016 at 2258UTC. A man in Japanese mentioning Tapei, a short musical selection plays before a few beep tones and a carrier being cut. The signal is pretty steady and strong with some light fading, but still a listenable signal. Audio here: https://www.youtube.com/watch?v=-K6NVvrriwY
9790 kHz, Radio Romania International in English via Tiganesti to the Far East. The English service broadcast with a lady talking about a contest with the giveaway being a CD. Details are given how to enter the contest. The signal was somewhat weak but there was a moderate amount of nosie with some fading on the channel. I detected the 9760 kHz in english to Western Europe and I could hear audio, but nothing worthy of recording or logging it “officially”. 9790 kHz audio here: https://www.youtube.com/watch?v=BGiD1OHVWKw
9870 kHz, All India Radio Vividh Bharati Service in Hindi via Bangalore to South Asia on July 27, 2016 at 1700UTC. They are here just about everyday, sometimes at poor levels but usually at least fair. However, some days like this time, they are good to excellent with great audio, steady signal and no real noise or fading. I love hearing the music they play! Audio here: https://soundcloud.com/onairdjpaulwalker/air-9870-july-27-2016-8-59-1
9997 kHz LSB, RWM Moscow Russia on July 27, 2016 at 1643UTC. Every source I’ve seen places them on 3 frequencies, including 9996 kHz. I swear each time I’ve heard them, it is clearer on LSB and 9997 kHz then 9996 kHz! They are a fairly regular visitor here, not every day, but at least weekly but usually, they are buried in the noise between slop from WWV/H and atmospheric crud. Well, this today the beep from RWM was very very much in the clear. Audio here: https://soundcloud.com/onairdjpaulwalker/rwm-9997lsb-july-27-2016-8
11800 kHz, Radio Romania International in Romanian via Tiganesti to the Middle East on July 27, 2016 at 1647UTC. The signal was fair with a moderate amount of fading and atmospheric noise. I heard a romanian language tune followed by a man then a woman talking. Later on, I heard what may have sounded like feature report of some kind, I don’t think it was a news broadcast. Audio here: https://soundcloud.com/onairdjpaulwalker/rri-11800-july-27-2016-8-47-16
11735 kHz, Zanzibar Broadcasting Corporation in Swahili via Dole, Zanzibar on July 28 at 1659UTC. They are only 50KW and while some sites list them as non directional, they aren’t. A directional curtain antenna has been spotted on Google maps, but I don’t know what their beam is. That being said, I can count on them being here daily. Somedays it’s poor, some days it’s fair and other days it’s somewhat good like this. There are even days when it’s near excellent with a clear, steady signal and good audio. In this clip, the audio sounds like a cross between being full of digital artifacts and some propagation issues. The audio is not as good as usual, but still pretty listenable with not much fading and little noise or interference. There was a song, followed by a little dead air then a station promotional announcement and another song. ZBC, when playing music, is an enjoyable listen! Audio here: https://www.youtube.com/watch?v=SSvyT-Do1cE
11950 kHz, Radio Romania International in French via Galbeni to Southern Europe on August 1, 2016 at 1640UTC. The signal was fair but with a moderate amount of fading. Thankfully, no interference or too much atmospheric noise. A woman talking in french, presumably reading the news. Audio is here: https://www.youtube.com/watch?v=PioNenuF358
12019 kHz, The Voice of Vietnam in Chinese(?) via Hanoi to Indonesia on July 31, 2016 at 2236UTC. I can usually hear the Voice of Vietnam shortwave broadcasts in multiple languages from their Vietnam based transmitter sites across very frequencies. This signal is fairly weak with some nooise and fading. It sounds like a news broadcast or feature report to me. Audio here: https://www.youtube.com/watch?v=L5GRlWGQbBg
12035 kHz, Voice of Mongolia via Ulaanbatar with 180 degree beam south from Mongolia On August 1, 2016 at 0900UTC, I had the best signal ever from time. If it wasn’t for all the atmospheric noise and fading present, the signal would’ve been an incredibly pleasant listen. During this time, I happened to catch the DX’ers mailbox program in which they read out a letter from me. However, this is the second time the July 4th broadcast has been replayed. Still great to get them so well here, usually they are weak and barely above the noise floor. My Wellbrook ALA1530LNP was used here instead of the 225 foot longwire. The loop provided noise reduction and nulling/directional capabilities that really helped out! Audio here: https://www.youtube.com/watch?v=bqTox0j8P3k (Here’s a tip when looking for VOM on 12035 and trying to log in: I think the carrier is turned on several minutes before the 0900UTC broadcast in english. The interval tune starts just a little before 0859UTC and I think the program runs the entire 30 minutes till 0930UTC, unlike what I think some sites suggest)
12060 kHz, Radio Algerienne via Issoudun to West Africa in French on July 26, 2016 at 2038UTC. none of Radio Algerienne’s signals are regular visitors and pretty weak as I recall, like this one with lots of noise and buzzing. Music and chat barely detectable above the noise floor. Audio here: https://www.youtube.com/watch?v=2pqdQKRrG0E
12095 kHz, BBC World Service in English to East Africa via Meyerton on July 23, 2016 at 1625UTC. A news broadcast in english, two men are discussing sports then a news anchor comes on to read the top stories. Audio here: https://soundcloud.com/onairdjpaulwalker/12095-bbc-english-to-east
13660 kHz, Radio Romania International in Romanian via Tiganesti to the Middle East on July 28, 2016 at 1655UTC. This was a GOOD signal with only a light amount of fading and very little noise. There was a woman talking for a bit then a man came on and mentioned the name of the station. A song played and the carrier was cut mid song without their usual interval tune. Audio is here: https://www.youtube.com/watch?v=WR7p0537mbc
15170 kHz, Radio Romania International in Spanish via Tiganesti to South America on August 1st, 2016 at 2101UTC. This signal was pretty weak with only a light amount of fading but plenty of atmospheric noise. It was hard to understand the woman talking, but you could clear make out the RRI news sounder noise part of the way through my recording. Audio here: https://www.youtube.com/watch?v=jzYQ3l4iPWE
15235 kHz, Channel Africa in English via Meyerton to Western South Africa on August 2, 2016 at 1708UTC. Channel Africa is somewhat of a regular visitor up here as of late when conditions are good. They broadcast an hour long news segment in French from 1600 to 1700UTC followed by an hour long english broadcast. The signal this time around is fair but there’s alot of fading. The signal can be weak at times, but is usually steadier then this. Audio here: https://www.youtube.com/watch?v=7k0-lx8aLXM
15275 kHz & 11740 kHz, Deutsche Welle via Issoudun in French to Africa (17740 kHz) and West Africa (15275 kHz)on July 31, 2016 and August 2, 2016 bewteen 1700 and 1730UTC. 15275 kHz french service to Africa was heard on July 31 and August 1st. July 31st produced a fair to good signal with moderate fading but still very listenable. The August 1st broadcast proved a bit harder, it was weaker and with a fairly high amount of fading and noise. The 17740 kHz was heard on July 31st and was fair but with LOTS of noise and fading which made it hard to understand. 15275 kHz audio here: https://www.youtube.com/watch?v=eNBfkK4-UT4 (July 31) and https://www.youtube.com/watch?v=zhcZ6ZLLDP8 (August 2). 17740 kHz audio here: https://www.youtube.com/watch?v=4fdirw8RxKs
15400 kHz, Radio Romania International in Spanish via Tiganesti to South America on August 1, 2016 at 2259UTC. There is a fair amount of noise in the signal and it’s somewhat weak, but still fairly listenable. The signal starts off with the usual and easily identified interval signal followed the opening of the broadcast, introducing it in spanish and continuing on with the news. Audio here: https://www.youtube.com/watch?v=jzYQ3l4iPWE
15770 kHz, DigiDX via WRMI Okeechobee, Florida on July 31, 2016 at 2149UTC. It is a very weak signal plagued with lots of noise and fading but I did get plenty of MFSK32 text to decode and a picture to come through on FLDigi. It wasn’t error free, but it was pretty good considering what the signal sounded like. Audio is here: https://www.youtube.com/watch?v=tFMxYTrGA6Q (Bring up FLDigi on your computer and play this video in the background, and you’ll see, stuff DOES decode!)
Yesterday, an SWLing Post reader contacted me with questions regarding budget antenna choices for an urban apartment. He’s about to purchase an SDR, but knows that a decent antenna capable of coping with urban radio interference is a critical component.
I suggested that, since I’m no expert with urban interference, he pose his question to the SWLing Post community. Here’s his reply and request:
I know I’m a little behind some of my other radio friends, but I’m finally moving up to a software defined radio. Specifically the affordability of the SDRplay RSP and all good reviews for it have encouraged me to make the leap.
The SDRplay RSP software defined radio
I suppose it should go without saying that once I purchase an SDRplay I would like to use it, which might not be so easy. I live in a big city full of RF pollution, and most of my listening will be in a room where there’s a fair amount of electronic gadgetry.
So, without spending a lot of money, I’m curious if any of your readers might have suggestions about what I might purchase as a “starter kit” for a new SDR user in such a scenario. I also plan to take the SDRplay with me when I have forays out of the city, but I envision that some sort of long wire might be sufficient for listening out in the countryside.
I live on the second floor in an urban apartment, and have two windows in the room where I’ll be listening. There is zero chance that I can hang or attach anything on the outside of the house here. So, my most pressing question is about antenna ideas. I’ll need something inexpensive, as I mentioned, and something “off the shelf.” I don’t have the skills or tools to really “build” anything, unfortunately. So is there some less than pricy antenna or antennas I should look at? Or is there some hope of doing something with a long wire indoors?
Tecsun AN-100 portable loop antenna
And will my little Tecsun AN-100 AM loop antenna going to help me at all? I mostly plan to listen to MW and the HF bands, but I will inevitably check out signals far up the bands as well. So advise about listening to these bands is also of interest to me.
Other than that, I understand it’s important to attach the SDR to the laptop with a USB cable with ferrite chokes. And it probably wouldn’t hurt to buy some extra ferrite chokes to attach to other cables I might be using. I also plan to buy a NooElec mini-balun for use with a long wire antenna, and I already purchased a PowerMate USB knob because I still prefer to do my “tuning” that way.
So other than those basics my questions would be regarding connecting cables and adapters, and the best lengths of cable to use. Should I have some cable between the balun and SDR? I believe I’ve read that it’s better to have a longer USB cable and a shorter coax to the antenna, correct? And when it comes to using a wire antenna, are there preferences as far as what type or gauge of wire to use?
I am also interested in any general suggestions or tips from SDR users on getting started. In general, I’m pretty good with navigating through software, it’s usually the hardware issues that stump me. I’m looking to spend between $100 to $150 tops on everything besides the SDR, and I’d like to hear about peripherals, cables, adapters and connectors which when added all together won’t bust my bank.
I’m sure there’s plenty of people who read this wonderful blog who have plenty of useful knowledge regarding SDR listening on a budget. And I hope a few could share a little of their experience and collected wisdom on this topic here, for me and for others considering turning their computers into receivers…
Indeed. I appreciate this reader’s question, since many listeners live in environments with heavy radio interference. While we’ve published a number of posts touting the virtues of magnetic loop antennas, I don’t think we’ve ever looked for solutions at or below $150 US. While this may be a challenge, I’m also certain there are a number of readers who’ve found solutions to this problem.
So, Post readers, what might you do–or have you done–in similar circs? Please feel free to comment, and let’s explore inventive and affordable solutions for this reader!
Many thanks to SWLing Post contributor, Clint Gouveia, who writes:
As the designated driver, I found myself waiting for friends at the Beyonce concert at Wembley Stadium last Sunday [July 3rd], Not wishing to miss an opportunity and taking advantage of 8 stories of elevation (top floor of the car park!) I spent about 3 hours DXing with the legendary Panasonic RF-B65 and a Wellbrook ALA1530 active loop, running on my home-brew battery pack.
Rather counter-ituitively, I quickly discovered there was basically zero QRM and recorded wonderful signals from Zanzibar BC, Radio Bangladesh Betar and Radio Oromiya. Links to the reception videos on my youtube channel ‘Oxford Shortwave Log’ follow below. I thought readers of your excellent website/blog might be interested to learn that sometimes the most unlikely of places can provide just about optimum conditions for DX! There are more reception videos for this particular session to upload,including Radio Fana, Voice of Tigray Revolution and Radio CANDIP.
Wow! What amazing reception, Clint! I would have never guessed that a car park next to the largest stadium in the UK would offer up such excellent listening conditions. Honestly–that Bangladesh Betar broadcast sounds like a local station.
You also have a great receiver there in the Panasonic RF-B65. If memory serves, the RF-B65 is also a favorite of SWLing Post contributor/DXer, Dan Robinson.
Post readers: Follow Clint’s many DX catches on his YouTube channel: Oxford Shortwave Log.
Thanks again for sharing, Clint, and reminding us that DXing locations aren’t always remote and exotic.
Conditions haven’t been so great lately and combine that with just being a bit tired and worn out means I haven’t DX’ed as much as I’d like. But I have spent a little time at the radio dials and when I do, I usually pull out a few good logs, so here we go:
3325 kHz, July 12 at 1025UTC. NBC Radio Bouganville with an absolutely LOUD, STELLAR signal. Audio was excellent and there was only light fading with no interference or noise. Survivor’s 1984 hit, “High On You” was playing during my recording. They seem to favor 80s and 90s rock or adult contemporary music when they play tunes. Audio of 3325kHz here:
5835 kHz AM (July 15, 1621UTC, 10871.70kHz USB (July 12 2049UTC) & 10861.90kHz USB(2052UTC). Russian Channel Marker. I’m not really sure where in Russia these come from or what their purpose is, as i am not very “up” on the utility type broadcasts on HF. The 5835 kHz beeping is pretty clear and evident, but it sounds like there’s a little interference coming from somewhere or someone else. The signal from the 10871kHz signals is pretty weak but the beeps do make it above the fading/noise, 5835kHz audio
5857kHz, July 15 at 1626UTC. “HLL Seoul” with a weather broadcast by a woman speaking Korean. Poor to fair signal with some noise and interference. Audio here: https://www.youtube.com/watch?v=jBNmrdyDDI4
7260 kHz, July 12 at 1001UTC. Radio Vanuatu in their local language with talk in the local language, a little preaching and some Christian music. The audio quality isn’t too great (sounds like it’s full of digital artifacts) but the modulation level is better then usual. Around 14 minutes and 35 seconds in, a female announcer comes on and talks for a bit then begins reading a sign off message then plays the Vanuatu national anthem. The carrier is left on for 10-15 minutes before being shut off. 7260 audio here: https://www.youtube.com/watch?v=jTnudTRmduk
7485 kHz, July 13 at 1636UTC. BBC Bengla service in Bengali language with a news broadcast. An absolutely stellar, steady signal with almost no noise whatsoever and no fading or interference. 7485kHz audio here: https://www.youtube.com/watch?v=hRDZKSDkSMk
7210 kHz & 9730 kHz, July 13 at 1628UTC and July 15 at 1643 UTC respectively. 7201 kHz is their broadcast in Vietnamese with 20kw via Daclac, Vietnam. Vietnamese music is heard at fair levels but with lots of noise and fading. Pretty decent considering what and where it is. As for 9730kHz, it’s The Voice of Vietnam in what appears to be the Russian language. A poor to fair signal with fading/noise and what appears to be interference from another station. 7210kHz audio here: https://www.youtube.com/watch?v=_xUpmAbpOW4 and 9730kHz audio here: https://www.youtube.com/watch?v=x2CE2QCgiD0
9515 kHz & 9640 kHz, July 11 1644UTC to 1652UTC. The 9515 signal is a bit stronger with slightly fess fading and noise. both are broadcasting the KBS World Radio english service with talk about travelers and tourists. 9515kHz audio here: https://www.youtube.com/watch?v=V0k77cY4DLA and 9640kHz audio here: https://www.youtube.com/watch?v=KhBxIPGHMh8
9526kHz, July 15 at 1645UTC. Voice of Indonesia with Arabic language speech and music. Fair to good signal with low modulation and some noise/fading but comparatively speaking, this is a VERY GOOD signal for what is usually heard on 9526 kHz! And yes, they are about as close to 9526 as can be. Zero beating them in USB with my PL880 produces a whine/noise till I’m right at 9526 kHz. One website, Eibi’s schedule says that are at 9525.9.. I suspect they may be even closer then that! 9526 kHz audio here: https://www.youtube.com/watch?v=U4WdKewnyWM
9665kHz, July 16 at 1715UTC. The Voice of Korea is heard here all day everyday but the audio is usually noisy and fairly poor(usually overmodulated) but this is a case of not only good audio but a pretty solid signal! 9665kHz audio here: https://www.youtube.com/watch?v=cMBLYV4icBQ
9770 kHz, July 11 at 1653UTC. KBS World Radio in Korean with men talking and a pretty steady, GOOD signal. Fair amount of noise and light fading. Audio of 9770kHz here: https://www.youtube.com/watch?v=tyXb3sg-1-o
9890 kHz, July 11 at 1729UTC. The Voice of Korea signing on in Arabic. Starts off as usual with a dead carrier, the interval signal and announcers mentioning the name of the signal. Noisy signal, but a much better signal then I’ve ever had from VoK on 9890kHz and the first time I’ve heard them here with log worthy audio! You can somewhat hear another station under them in this recording, and normally, that staion is usually on top VoK on this frequency. 9890 kHz audio here: https://www.youtube.com/watch?v=ftVaztXipTg
10005 kHz, July 12 at 1705UTC and July 16 at 1718UTC. For the 2nd and 3rd time in 6 months, I’ve heard the Chinese Firedrake jammer on 10005 kHz. The first time several months ago, it was so strong it was interfering with WWV & WWVH. These last two times it was fairly weak but what made it even more interesting both times is I heard time pips underneath the jammer. If you listen closely in the two following clips, you can hear the tips and you can clearly hear a longer louder tone signifying the minute mark. July 12th clip: https://www.youtube.com/watch?v=t3X3iIs41PE. July 16th clip: https://www.youtube.com/watch?v=dClTJkpat30
11665 kHz, July 13 at 1647UTC. RTM Wai FM with an overall very good reception, good audio and steady signal. Only a slight bit of fading. This is by far the best I’ve ever heard this frequency here! 11665kHz audio here: https://www.youtube.com/watch?v=iw4oVv1hzOI
11735 kHz, July 11 at 2033UTC. Zanzibar Broadcasting Corporation with music and talk in Swahili. This is about the usual kind of signal I get from them, fair to the low side of good with some fading and noise. At times, there signal is even steadier, stronger and less noisy then this. They are listed as being on till 2100UTC but I’ve heard them sign off anywhere between about 2045 and 2058UTC in mid song with no announcement of any kind. In this nearly 19 minute recording, they sign off at 17 minutes and 33 seconds in. Some type of RTTY/data broadcast has recently appear in the last few months on 11735kHz causing interference, severe at times, with Zanzibar on 11735kHz. Audio here: https://www.youtube.com/watch?v=gZiG_nslSi0
12015 kHz, July 11 at 1703UTC & July 13 at 1652UTC. In the July 11th clip, you can hear CRI & VOK fighting it out together, with the two trading places back and forth. If either has a silent carrier, you can clearly here one of them. In the Jul 13th clip, Voice of Korea is on the frequency alone. 12015kHz audio here: https://www.youtube.com/watch?v=OyKCnQ8DLCQ and https://www.youtube.com/watch?v=LF3PNWT69Fw
12035, July 12 at 0859UTC. The Voice of Mongolia. The signal is incredibly weak and this is a good catch if their beam is headed straight south from the transmitter site in Mongolia. Their interval signal pops up out of the noise a few times and you can hear a male announcer say the name of the station in Mongolia before the English language service begins at 0900UTC.

13605kHz, June 25h, 1058UTc. All India Radio with fair signal but lots of fading and noise, this is better then what I usually get from AIR. 13605 audio here: https://www.youtube.com/watch?v=d03wQHXB-dA
13710kHz & 15435kHz, 1705UTC & 1705UTC. Radio Saudia/BSKSA. The 13710 signal was a bit better strength wise with chanting/Arabic music. The 15435 signal had men talking, like a news or interview program and was a bit weaker. 13710 audio here: https://www.youtube.com/watch?v=0t3YP8RCZY8 and 15435 audio here: https://www.youtube.com/watch?v=xr3tgnRBSn4
15275 kHz, July 16 at 1724UTC. Deutsche Welle in French, a very noisy signal with lots of fading. Sounds like a news or interview program with a man and woman speaking. Any DW signal is pretty rare here! Audio here: https://www.youtube.com/watch?v=lChqqJH2crc
17730 kHz, July 13 at 1658UTC. Eye Radio, broadcasting to South Sudan. A very very weak signal with tons of noise and fading. I can barely make out a man speaking before the carrier drops at 1700UTC, which is Eye Radio’s sign off time. Audio here: https://www.youtube.com/watch?v=W-CphVmuJSA
17740 kHz, July 16 at 1732UTC. Deutsche Welle in French with a signal even noisier and worse than 15275kHz. It very well may have been the same broadcast as what was on 15275kHz that I heard minutes earlier. Any DW signal is pretty rare here! Audio here: https://www.youtube.com/watch?v=lChqqJH2crc
17775 kHz, July 13 at 1706UTC. KVOH which a preacher speaking in Spanish. Weak and noisy but steady signal. This may be the first time I’ve heard KVOH here and I consider this a good catch since they beam to Mexico and Central/South America. Audio here: https://www.youtube.com/watch?v=aqegTkffahA
17850 kHz, July 13 at 1702UTC. Radio France Internationale with a weak, noisy, fading signal. Women talking in French during a news broadcast. Audio here: https://www.youtube.com/watch?v=ujnbGMo8Tww

The 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.
