Many thanks to SWLing Post contributor, Mike S, who comments with his short review of the Sangean HDR-14. Mike writes:

Well, I did something I said i would not do, triggered by Amazon’s tendency to introduce impossibly low prices on things for a couple of days, I sprang for the HDR-14. I have used it side by side with its direct competitor (the Nicetex “SPARC” SHD-TX2) for a few nights and a couple of days. Interesting little device.

As has been pointed out by those that read the specs, it is barely larger than the CC Skywave overall. It is made of the same soft, shiny black plastic as the larger Sangean portables (it is alternately a fingerprint magnet or a scuff magnet) but has a much less solid feel. The swivel-out foot on the bottom is a welcome addition and works well.

I have not yet played with other features (memories, etc) except to note that somebody has finally gotten it right in that memory locations store the chosen FM multicast channel instead of just the frequency.

Performance is a mixed bag. This is NOT an HDR-16 crammed into a smaller cabinet; not surprising, really, considering the amount of real estate available for circuitry. Analog FM and HD capture are right up there with the the larger sets and similar to the SPARC. I am unable to reproduce the spurious FM image problem noted by a lone Amazon reviewer. Audio is “just OK” out of the speaker with a harsh emphasis on treble – the SPARC portable is MUCH better with its passive radiator – but just fine for headphones or an external speaker.

However, for AM, that reviewer was spot on. The noise floor on AM is a tad too high and the native sensitivity a tad too low; resulting in “just OK” useable sensitivity on the band especially compared to the SPARC. I had no trouble with AM-HD on the only two stations in NYC metro (WCBS and WINS); however, it was unable to even detect the HD carrier from known stations in nearby cities that I was able to get >50% on the HDR-16 and HDR-18. The selectivity is better than the SPARC due to the DSP active for bandwidth adjustment; witness that I was able to clearly separate stations in Connecticut (600) and Philadelphia (610) from the splatter of local powerhouses at 570 and 620. Unfortunately too, analog AM reception is plagued with DSP artifacts reminiscent of earlier Tecsun sets which can even manifest in odd distortion in adjacent-channel splatter that bleeds into the tuned signal. The fact that the audio circuit/speaker accentuate the treble, make this even more annoying – the “ticks” from adjacent channel splatter are so harsh that you might think the speaker cone is damaged and vibrating.

I’m still waffling on whether to keep this one. It’s a nice little set which is sure to become a collector’s item, and its FM performance really is exemplary. But I kinda view the inclusion of the AM band as its raison d’être and in that regard it could certainly do better.

Thanks for your review, Mark!

It’s interesting that you couldn’t reproduce FM overloading or imaging. I have noted images on the FM band and it hasn’t been in a market as congested as that of NYC. It’s only noticeable when listening to stations adjacent to strong signals, however. It’s almost as if the FM filter is a little too wide.

I also agree about analog AM reception.

My HDR-14 review has been delayed due to a very hectic schedule, but I plan to complete it in the next couple of weeks! Thanks again, Mike!

Impressive Transatlantic FM DX: Newfoundland to Northern Ireland on 88.5 MHz

88 MHz Trans-Atlantic signals heard in Ireland

On Sunday the 8th of July 2018, there was a remarkable opening on the VHF bands across the North Atlantic. While there were plenty of strong multi-hop Sporadic-E signals on the 28 MHz and 50 MHz bands, the maximum qusable frequency did reach as high as 88 MHz at one stage.

Paul Logan in Lisnaskea, Fermanagh, Northern Ireland managed to catch CBC radio 1 on 88.5 MHz from Newfoundland, Canada at 22:35 local time (21:35 UTC). It is very rare for openings on Band 2 across the Atlantic and to date, only two people have managed to succeed in hearing North American radio stations.

Jeff discovers that the Sangean WR-2 loses time when playing radio

Many thanks to SWLing Post contributor, Jeff McMahon, who writes:

I wanted you to know that my Sangean WR-2 keeps perfect time when I don’t play the radio, but when I do play the radio I lose 25 minutes; the clock is 25 minutes slow in other words. I’ve read other complaints from Sangean owners, including from those who own the Sangean HDR-18. Some say it has something to do with RDS. Have you heard of this problem? It’s annoying because I have to reset my clock every morning.

Wow–an otherwise excellent radio that prominently features a clock should never have this problem. This problem essentially renders the clock useless. I’m not sure what would cause this unless it’s incorrectly pulling time data from the RDS function?

Post readers: Have you noticed this fault in the WR-2, WR-18 or other similar models? Please comment.

Chris’ review of the Sangean WR-7 FM radio and Bluetooth speaker

Many thanks to SWLing Post contributor, Chris Freitas, who writes:

I recently came across a post on the SWLing Post after I saw Sangean released the WR-7. It recently became available on Amazon and decided to purchase one after seeing your review and Radio Jay Allan’s review.

As I am writing this, I am pleased with the overall quality of this radio. The dark walnut wood is a nice solid build and the light-up dial is a nice touch.

The sound quality is fantastic and beats the pants of my larger iHome “Orb” Bluetooth speaker and sounds a bit better than the Jambox Mini.

I have not done a lot of FM listening yet, but this little radio is pretty sensitive without the wire antenna. It picks up all of the Memphis FM stations with little or no static. With the included wire antenna, I can receive WMAV 90.3 FM in Oxford, MS…about 80 miles away with ease.
The WR-7 is definitely a keeper and will be using it on trips and between rooms in my apartment or outside while sipping on some coffee.

Anywho, I wanted to tell you about my experience with the radio and I have included some pictures of it too.

Thank you for sharing your report, Chris! You’re right: the Sangean WR-7 is a fine little FM radio and Bluetooth speaker. I’m happy to hear how well it’s serving you and even snagging distant FM stations. Later this year, I’m going on an extended trip and will take the WR-7 with me to provide a nice source of local FM music and WiFi radio while paired with my iPad running TuneIn.

The Brooklyn Pirate Radio Sound Map is live!

3 Replies

I’m happy to announce that my friend and radio producer David Goren has released the Brooklyn Pirate Radio Sound Map: a detailed interactive website exploring the dynamic pirate radio scene in Brooklyn, New York:

“In Brooklyn, when the sun goes down, pirate radio stations fire up their transmitters and take to the air, beaming transgressive, culture-bearing signals into Caribbean, Jewish and Latino neighborhoods. The Brooklyn Pirate Radio Sound Map is an archival home for the sounds of renegade community radio at a crucial turning point in its history.”

The site includes a map and virtual radio pre-loaded with off-air recordings of dozens of pirate radio broadcasters.

Over the past few years, David has put a lot of time and research into this project and I’m pleased to see it come to fruition in such a rich format. You could spend hours exploring the sound map.

Brilliant job, David!

Aeronautical RDS: Ivan’s impressive collection of in-flight FM stations

Many thanks to SWLing Post contributor, Ivan Cholakov (NO2CW), who writes:

Last week I took an Eton Satellit with me on a flight from Tampa, Florida to Washington DC. The radio is very light, portable and packed with features. I have used an SDR radio before for inlight FM reception where I recorded audio, but this time I decided to only count stations with an RDS lock. With so many signals battling RDS is tricky to catch as every 10 seconds or so one station comes on top of another. The flight was just short of 2 hours and I divided my logs into three 30 minute segments. Not suprisingly looking into the technicalities I noticed RDS is commonly received from stations 50 -100 kW of power and tall towers.

Interestingly signals seem to be stronger a lower altitudes. My theory is that FM broadcast antennas heavily favor gain on the horizontal plane parallel to the terrain and send as little signal as possible out into space. I overlaid my logs onto three maps and also a video:

Impressive Ivan! I’m taking a flight later this month and might even try this with the FM radio built into my Moto G6 smart phone which also includes RDS (although I doubt reception can match that of the Satellit.

This is fascinating, Ivan! Thank you for sharing.
