Sangean DT-140 & SR-32: New Sangean AM/FM radios


Many thanks to SWLing Post contributor, Michael Schuster, who writes:

The Sangean SR-32 from the 2020 catalog.

Attached image [above] is extracted from a PDF of the 2020 catalog, it shows the
upcoming Sangean DT-140 and SR-32.

Wondering if the SR-32 (from the almost-defunct “slide rule” series) uses DSP-as-analog tuning like its larger sibling with speaker.

Thanks for the tip, Mike!  Yes, I’d be willing to bet that the SR-32 is DSP-based. I might have to check these out further.

It’s also nice to see that they also feature both the ATS-909x and ATS-405 shortwave portables in the 2020 catalog!

The Verge: “Who’s afraid of the PIRATE Act? Not Joan Martinez”

Many thanks to SWLing Post contributor, Mark Hirst, who shares this article from The Verge:

When she was growing up in East Flatbush among the Haitian diaspora, former pirate broadcaster Joan Martinez — no relation to the New York radio legend Angie Martinez, despite what Joan claimed to her friends as a youth — said that the sounds of pirate radio were the backdrop to her childhood. “Starting Friday night, all throughout the weekend, you would just hear all these like crazy DJs just talking and all this music,” Martinez says. Her parents’ apartment was the meeting spot for her whole family, a place where they’d reminisce about being in Haiti. They needed a place that felt like home. Martinez says that, as a kid, she never understood why the stations they listened to only broadcast on the weekends. As she got older, there were fewer of them — and then in 2010, she says, they started to come back online.

Martinez got into the scene as a broadcaster after her mother turned down an offer to be a DJ at a pirate station. “She was like, ‘No, I don’t want to. However, I do have a daughter that did study broadcasting in college,’” — Joan — “and then all of a sudden they were like, ‘We want her. Like, can we bring her in here?’” Martinez went. It was 2010. Her first job was as an anchor, where she talked through the news from the Caribbean and New York City. Then she filled in for a couple of high school girls who had their own show — and eventually took the spot over completely. It was a talk show she did with her friends for a year and a half, until Martinez decided to go back to school. (“It was a pretty live show. Sometimes things get a little raunchy, sometimes things get a little too crazy and it’s like, I don’t want to piss off my supervisor,” she says. Pirates have org charts and standards, too.)

After school, she went back, but not for very long; academia pulled her back in, and today, she’s in grad school, currently at work on her thesis. “I was doing pirate for a good five years and then when I got into grad school, since the coursework was becoming very time consuming, I had to kind of let that go,” Martinez says, adding that she’s mostly involved these days in an administrative, consulting way. “However, you know, I still keep my fingers in their pot.”[…]

One of our contributors on the Shortwave Radio Audio Archive, Tom Gavaras, has been sharing some brilliant airchecks. I also discovered that Tom runs an amazing site simply chock-full of Minneapolis/St. Paul airchecks. Tom writes:

Hi Thomas,

[…]As an FYI … I own/run a website called RadioTapes (www.RadioTapes.com). It features more than 2,000 airchecks of Minneapolis/St. Paul radio stations dating back to 1924. You will also find some shortwave recordings that I previously posted (on the Special Postings page).

In addition to my collection, the website includes airchecks provided by more 100 contributors. RadioTapes also has a Facebook page with 1,400 followers.

Post readers: I strongly suggest you check out Tom’s amazing archive of airchecks.  If you ever lived in or DXed the Minneapolis/St. Paul market, you’ll certainly hear some familiar voices and IDs.

Thank you Tom!

Thanks for sharing, Paul. We’ve mentioned the Public Radio before, but I did not realize they were completely produced and assembled in the US.

Post Readers: Please comment if you own a Public Radio. I’m very curious what you think about the audio fidelity.

Swiss Army Knife FM antenna

Many thanks to SWLing Post contributor, Balázs Kovács, who shares the following video of a Swiss Army knife and tweezers being used as FM antennas:

Thanks for sharing this, Balázs. The video actually makes a good point: it takes so little to make an effective FM antenna to receive local stations. I’ve been with repair technicians when working on radios They’ll often use their precision screwdriver as an antenna to test the receiver before reassembly.

I also carry a couple cheap instrumentation patch cord with alligator clips on both ends to act as a short antenna or antenna extension when needed. Honestly, It’s amazing how often I reach for them!

A review of the Sangean PR-D17 portable AM/FM radio for the visually impaired

Many thanks to SWLing Post contributor and producer, Peter Atkinson, who shares the following review of the new Sangean PR-D17 AM/FM radio:


Sangean PR-D17 review

by Peter Atkinson

I’ve been visually impaired all my life and a radio enthusiast for over 40 years.  I was intrigued when I learned that Sangean was offering a radio for the visually impaired.  I purchased one, and wanted to share my thoughts about the Sangean PR-D17 from the perspective of a visually impaired listener.

Photo of the PR-D17 box

For those readers who are mainly interested in the performance of this radio, please stay tuned, while I talk a moment about the features geared to the visually impaired.

Photo of the radio manual.

First of all: the manual, [see photo above] while it is comprehensive (as most from Sangean are), it is odd that it’s printed in the smallest type I’ve seen from this manufacturer.

Image of the PR-D17 tactile preset keys with Braille.

The yellow controls on a black radio are easily seen.  I like that the preset buttons on the bottom row of the front panel, are in Braille.  The raised symbols, however, on the upper row, may be too complicated to be easily discerned by touch alone.  The yellow-on-black motif, is reminiscent of my Sangean HDR-16.

When the 6 C batteries are first inserted, or AC power is connected, the radio announces that it has entered the setup menu.  The voice prompt menus (whose volume can be adjusted independently of the radios’ main volume but cannot be disabled) make setting up this radio somewhat straightforward.  The setup might have been easier, if the clock setting function was available as part of the menu system. The voice prompts are surprisingly comprehensive. The voice not only speaks the frequency, time & menu options, but will also tell you when something is connected to (or disconnected from) the AC input, headphone or AUX-IN jacks.

When the radio is turned on, it announces that the radio is on, the battery level & the frequency to which it is tuned.

When tuning, the voice gives the frequency at each change. It’s especially helpful when using the seek function, knowing where the next station was found.

When storing a station into a preset, the voice says exactly what frequency has been stored & at which present position.

The same information is given when recalling a preset. One quirk of the voice prompt, is that when announcing the time, it speaks full numbers (e.g. “twelve thirty-seven’), but when giving the frequency, each digit is spoken (e.g. “one two three zero” or “nine six point one”).

Finally:  Tuning time.

Comparing the Sangean HDR-16 with the PR-D17

This radio is the same cabinet as the HDR-16.  Aside from the voice prompts, it operates similar to the PR-D5.  Therefore, I’m comparing its performance to that model. Like the PR-D5, the AM tuning steps can be set for 9 or 10KHz, but the FM tuning steps are fixed at 100KHz (0.1MHz).

Image showing right side of radio.

There are 5 presets per band. The display also shows RDS information for any FM station that transmits RDS. The clock can be set from the RDS signal, as well.  I’ve found several stations, in my area, that are sending the wrong time.

Audio

The sound from the twin 2-1/2” speakers is very balanced.  The bass is substantial, but not overpowering. The highs are good for definition, without being too brassy.  There are no provisions for customization, though.

Image showing left side of radio.

There is a 3.5mm AUX-IN jack for connecting an external sound source, such as an MP3 player or smartphone.

AM

While the AM sound is a bit muffled for my taste (the bandwidth cannot be changed) it makes for excellent selectivity.  There was no hint of my nearby 50KW 620, on 610 or 630. Like many Sangean radios, the noise floor is very quiet. The long 200mm internal ferrite bar antenna does a superb job at snagging those weak stations.  I was able to get a noisy, but readable signal on a 50KW station on 700, at 350 miles, during the day. That one is my benchmark for a great DX machine. The top end of the band is no slouch, either. Another benchmark station (10KW 1690 at 75 miles) came in loud and clear.  The long ferrite antenna also helps to better null unwanted signals. This is a greater benefit for nighttime DXing.

FM

The PR-D17’s performance on FM is stellar.  It has shown to be very sensitive, pulling in stations as well as my PR-D5 & PR-D9W.  I easily hear FMs at 60 miles. The selectivity is also amazing. I can listen to stations on 95.9 & 96.3, with a 6KW station on 96.1 less than 10 blocks from my window.  Even though the PR-D17 pulls in those weak stations with ease, it requires a stronger signal to receive stereo.

Close up of RDS display

The RDS is quick to display station information. It starts off by showing the 8-character PS information of the RDS signal, then switches to the scrolling display of the RT segment.

Summary

Overall, I am very happy with the Sangean PR-D17.  It is a superior radio, now with the added benefit of voice prompts.  Hopefully, this will alleviate some of the annoyances visually impaired listeners may have with operating a digitally-tuned radio.


Thank you so much for sharing your review, Peter and thank you for being an SWLing Post producer!

It looks like the Sangean PR-D17 is an excellent choice for those radio listeners who would appreciate voice prompts, high contrast controls and tactile keys. I’m also happy to hear you rate AM selectivity as excellent. When radios only have one chosen bandwidth, I’d rather give priority to selectivity than audio fidelity for the purposes of nighttime AM DXing.
