Many thanks to SWLing Post contributor, Gene Paradis, who writes:
I have something to share…It is on every night on 5.620 MHz around 010 UTC some folks talking language unknown..It goes on most of the night..This is an aero frequency but these folks are there every night. Hope to find out more. Maybe fishing vessels or something else–? It is these mysteries that make this hobby fun!
My schedule as of late has not allowed dedicated listening time on this frequency. I would certainly suspect fishing vessel communications, but can’t confirm.
Post readers: can you help Gene identify this over-the-air chatter? Please comment!

The Sangean WFR-28 WiFi Radio
Many thanks to SWLing Post reader, Dave Mackie, who writes:
I have a Sangean WFR-28 that just stopped working recently and through a bit of internet spelunking I happened across your site and explanation about Frontier Silicon as ‘aggregator’ for Sangean. A phone call to Sangean confirmed that Frontier Silicon was having a problem with the aggregation service.
First off, thanks for the three part series on internet radio; it gave me just enough of a hint that the problem with be something other than the radio despite the fact that other wifi things were working properly.
[After contacting Frontier Silicon, I received] this unhelpful reply:
Unfortunately, we are having some difficulties with the internet radio service provided to us by a third party, which causes products not to be able to tune to any internet radio stations.
We are working on addressing the issue, and should have it up and running, hopefully within the next 12 hours.
Apologies for any inconvenience.
On one hand we’re getting a service that’s ‘free’ in that we don’t send a check directly to Frontier or the 3rd Party
We press a button and the radio just works.
On the other hand, the radio can inexplicably just stop working and we have absolutely no way to fix it.
Again as you mentioned, perhaps ‘closed’ vs. ‘open’ aggregator could (should?) be more well-known and more of a factor when choosing a radio.
I’d like more preset buttons on my Sangean WFR-28, but way more than that, I want it to work!
 Many thanks to Dave for sharing this experience with us–I imagine other readers may have caught this lapse in service as well. Fortunately, the problem Dave referred to was fixed within a 24 hour window.
I believe the “third party” Frontier Silicon relies on is vTuner. If I understand correctly, Frontier Silicon actually pulls all of the station linking information from vTuner’s database.
So you can see why aggregation aggravation could occur: there are no less than three companies involved when you “tune” your Sangean WiFi radio.
Sangean makes the radio which has software that links to Frontier Silicon’s portal. You log into Frontier Silicon’s portal to create a user account and manage your station favorites. But in the end, Frontier Silicon uses vTuner as a station database.
If any one of these links fail, the result may be a dead WiFi radio.
On the positive side, I listen to a Como Audio Solo radio most mornings. The Solo relies on the same aggregator chain as Sangean radios and I have never experienced an outage. I might be lucky, but I don’t think outages are all that common.
It would be great if there was a community-powered aggregator–something akin to a Wikipedia of Wifi radio–that would serve as a database for our Internet receivers. I could see a model where radio stations manage their own stream data and coordinates and listeners could even be approved to help manage link integrity. Sadly, I know of no such aggregator at present (readers, please correct me if I’m wrong about this).
Aggregators used by OEMs (like Sangean) are backed by a company ( Frontier Silicon, vTuner, TuneIn, iHeartMedia, Reciva, etc.) that have a financial interest in serving up-to-date station information to its customers. In the end, it still takes a human to physically add, delete or alter station information.
Since there’s money involved, it’s in the aggregator’s best interest to take care of problems quickly and efficiently. In truth, I worry less about the time it takes to fix problems or add stations–I worry about the aggregator going out of business. This happened in the early days of WiFi radio when some smaller manufacturers chose to run their own aggregators. If their company closed shop, their products were essentially useless.
Post readers: Have you ever owned a Wifi radio that stopped working due to aggregator failure? Have I missed a point here? Please share your thoughts!
Do you enjoy the SWLing Post?
Your support makes articles like this one possible. Thank you!

This has more to do with Public Relations than the technical aspect of Field Day. You may want to consider these for your Field Day effort if you set up in a public setting with the intention of talking up Amateur Radio. These are a few new ideas that we (SPARC) came up with for our 2019 outing.
Guest book - I don’t know why we haven’t thought of this before! We will have a guest book by our public information table/display. It’s useful for keeping track of guest operators, but also for anyone from the general public who has come by and shown interest in our hobby. Space for name and e-mail is probably sufficient - some people get uncomfortable with leaving too much personal information
Posters - We decided to purchase a pack or two of these from the ARRL:
We’ will add the necessary info in the blank box, and we’re hoping that the local merchants around town will be so kind as to display these in their windows or bulletin boards.
Signs - In addition to our club banner, we had some small signs/banners printed up by VistaPrint during one of their many on-line sales. It is a series of 1.5 X 3 foot signs that we will display in front of or close to important areas of our Field Day site. We felt that these would be good to explain to people what is going on that may be too shy to actually come up and ask any of us about what’s going on.
For example, one will say “Solar Power - we use this solar panel to charge the batteries that power our radios.” This will go close to the solar panel.
“Portable tower/antenna - this ladder holds the antenna that we use to communicate around the country and the world.” This of course, will be close to the tower, but far away enough to be at a safe distance from it.
We have a few others to go by the communications tent, by the information tent, and so on. We’re not certain that these will have any real effect, but they were relatively inexpensive and it’s our hope that they will give our Field Day site a more hospitable atmosphere.

Hybrid SDR Configuration
In addition to the Narrow band SDR receiver, that boasts overwhelming Basic Performance, the Hybrid Configuration Digital Processing with Direct Sampling SDR permits inclusion of the superb Real-Time Spectrum Scope. *300Hz and 1.2kHz roofing filters (Optional)
Narrow band SDR
Crystal Roofing Filters produce phenomenal Multi-signal characteristics
The Down Conversion type receiver construction is similar to the FTDX5000. The first IF frequency is 9 MHz, and a low noise figure dual gate MOS FET, D-quad DBM (Double Balanced Mixer) with excellent intermodulation characteristics, is implemented in the mixer section. Narrow band SDR configuration makes it possible to use the narrow bandwidth crystal roofing filters that have the sharp shape factor. This achieves the amazing multi-signal receiving performance when confronted with the most challenging on-the-air interference situations.
In addition to IF down-conversion, The FTDX101 receivers implement the YAESU legendary powerful RF Front-Ends, outstanding low-noise Local Oscillators, roofing filters with sharp shape factors, and the latest circuit configurations that we carefully selected for all circuit elements. Consequently, the proximity BDR (Blocking Dynamic Range) in the 14 MHz band reaches 150 dB or more, the RMDR (Reciprocal Mixing Dynamic range) reaches 123 dB or more, and the 3rd IMDR (third-order Intermodulation Dynamic Range) reaches 110 dB or more.
Narrow band SDR + Direct Sampling SDR
Emphasizes Excellent Receiver Performance and Hybrid SDR Functionality
Digital Processing Generated Real-Time Spectrum Scope
The Narrow band SDR receiver removes strong out of band signals by using a superheterodyne method, with narrow band roofing filters which significantly attenuates unwanted out of band frequency components, and the wanted signals within the passband are converted to digital by a high resolution 18-bit A/D converter and sent to an FPGA (Field Programmable Gate Array) for signal processing.
The FT DX 101 series uses a hybrid SDR configuration that integrates a direct sampling SDR receiver in order to view the entire band status in real time, with the excellent dynamic receiver performance achieved by the narrow band SDR receiver circuit.
By using this hybrid SDR design, the overall performance of the entire FTDX101 receiver system is improved. The Direct Sampling SDR driving the real time Spectrum display with its large dynamic range enables the weakest signal to be observed on the display when it appears and the Narrow Band SDR enables that signal to be selected, filtered and then decoded.
If there is powerful AM station near your location or in challenging operating situations where there are a lot of strong signals in the band from Contests, DX-pedition activities, those signals outside the pass band can be attenuated by the very effective roofing filter in the front stage of the A/D converter. This reduces the signal load on the A/D converter which is a bottleneck from the viewpoint of the entire receiving circuit. Therefore, interference is reduced making it is possible to continue to operate even under such difficult conditions.
Truly Quiet and Clear Reception
Ultra Low-Noise Local Oscillator System; 400MHz HRDDS (High Resolution Direct Digital Synthesizer)
The C/N ratio (signal-to-noise ratio) of the local signal injected into the 1st mixer is an important factor in improving the proximity multi-signal characteristics. The local circuit of the FTDX101 series uses the 400 MHz HRDDS (High Resolution Direct Digital Synthesizer) method that was used in the FTDX5000. This circuit configuration is different from a generic PLL that generates a local signal. Creating the local signal by directly dividing the high frequency of 400 MHz, the theoretical PLL lockup time becomes zero, and C/N deterioration by the lockup time does not occur.
The significant improvement of the C/N characteristic by directly dividing the frequency contributes dramatically to reduce the noise in the entire receiver stage, and also improve the BDR (Blocking Dynamic Range) characteristic in strong signals proximity.
In the FTDX 101 series, in addition to the adoption of the 400 MHz HRDDS, the latest circuit configurations that reduced noise, and carefully selected components are used. As a result, the phase noise characteristic of the local signal achieves an excellent value of -150 dBc/Hz or less at 2kHz separation.
This low-noise, high-quality local signal contributes significantly to the multi-signal and the ultra-close signal proximity (such as a few hundred hertz) characteristics.
Unparalleled -70 dB Maximum Attenuation VC-Tune
Newly developed VC-Tune RF Preselector with high precision stepping motor drive provides outstanding attenuation characteristics
Frequency automatic adjustment RF Preselector VC-Tune
In the FTDX101 series, a next-generation RF preselector VC-Tune further improves the high-performance RF μ (mu)-Tuning system adopted in FTDX9000. Using a remarkable miniaturization design while producing unparalleled characteristics and maximum attenuation of -70 dB.
Newly developed VC-tune circuit drives a variable capacitor (VC) with a high precision stepping motor and achieved remarkable miniaturization over μ-tuning system.
VC-Tune has no annoying steps or switching relays by continuously covering the band with a variable capacitor driven by a high-precision stepping motor following the frequency. The conventional preset method of switching coils and capacitors with relays is eliminated.
When there are multiple strong signals in the band, press the “VC TUNE” key and turn the MPVD (Multi-Purpose VFO Outer Dial) ring on the VFO dial to activate the high-precision stepping motor to adjust the variable capacitor. Fine tune to the optimum point that attenuates the strong signal in the band while operating the VFO dial.
VC-Tune stores the last tuning point for each band, so when broadcast-like signals are periodically transmitted on the same frequency, that frequency can always be attenuated by setting the VC-Tune once.
The Highest Transmit Signal Purity
High-Quality transmission with outstanding phase noise characteristics
Transmit Final Stage produces the Highest Signal Purity
The excellent C/N characteristics provided by the 400MHz HRDDS (High Resolution Direct Digital Synthesizer) used in the local oscillator circuit also contributes significantly to the transmitter section. In a generic circuit, noise or distortion may occur depending on the circuit configuration and the components, up to the final stage that is producing the transmit signal, even if the local signal is of high quality. In the FTDX101, a thorough examination of each element up to the final TX stage was made. The clock that divides and distributes the local signal from the 400MHz HRDDS circuit to each block, as well as the FPGA, D/A converter, the final power amplifier etc., and carefully selecting the latest circuit configurations to improve the C/N characteristics of the entire transmitter block. The transmit signal of the FTDX101 is directly generated from a 16-bit D/A converter without passing through a mixer circuit, therefore distortion and noise are significantly suppressed.
As a result, high-quality local signal characteristics are maintained without degradation to the final stage, and the transmission phase noise characteristics achieve -150 dBc/Hz at 2kHz separation. FTDX101 transceiver user will appreciate the finest performance with a high-purity transmission signal.
New Generation Scope Display 3DSS
Intuitively grasp changes in the strength of the signals
Newly developed 3DSS (3-Dimentional Spectrum Stream) system
in addition to a conventional Waterfall display
7-inch TFT Color Touch Panel Display
Size: 7-inch Wide
Resolution: 800 x 480 pixels
ABI (Active Band Indicator) & MPVD (Multi-Purpose VFO Outer Dial)
Deliver Superior Operability and Visibility plus Introduce Numerous Functions
Front Panel Design Emphasizes Solid Superior Touch and Operability
Primary important operation functions such as the Main VFO dial, VC-TUNE, WIDTH/SHIFT are arranged near the center of the pane for easy access.
Band select keys are placed as a row of ABI (active band indicator) at the top of the VFO dial, with your operating efficiency and comfort.
Even with a Large 7-inch Touch Panel Display, the panel layout emphasizes quick visibility and operability as a First Priority.
ABI (Active Band Indicator)
ABI is arranged as the band select key in the horizontal a row at the top of VFO dial.
When the band selected as MAIN Band, the LED indicates in white, and when the band selected by SUB band, the LED indicates in blue. At the status of transmission, the LED turns red so you can instantly confirm which VFO is transmitting.
In addition, since the orange LED lights up when you press and hold the band key, you can use it to display a band that has an antenna connected or to display a band operated in DX-pedition mode as a memo. Below the band key is a key for selection between transmission and reception of the MAIN and SUB band, and below that, there is a switching key for using the VFO knob on the MAIN or SUB tuning, so, even when the operating split using both MAIN and SUB bands at the same time, the band control can be performed smoothly, and so tuning the wrong band by mistake is reduced.
MPVD (Multi-Purpose VFO Outer Dial)
The MPVD is a large high-grade aluminium multifunctional ring around the outside of the VFO dial. The ring allows control of SUB VFO frequency dial, VC-TUNE, Clarifier and C/S (custom select function). The MPVD is a handy dial that allows you to adjust important functions in ever-changing HF communications without taking your hand off the VFO. The ring has the traditional Yaesu outstanding smooth and solid feeling when used.
PC Remote Control Software to Expand the Operating Range
Even from a distance, Dual Band-Scope Available Comfortable Operation utilizing the advantage of Hybrid SDR
Remote operation connected to LAN or Internet
PC control software performed remote operation of the transceiver from a remote location via the LAN or the Internet is available. (Requires optional external LAN unit)
In remote operation, in addition to the transceiver basic operation, it is compatible with DUAL-BAND scope and versatile displays, enabling comfortable operation. Also, you can enjoy various usages such as monitoring the band condition on a large display at a place away from the shack by connecting to a home LAN.
By communicating of Transmit/receive voice, RF scope, AF scope and CAT command to the transceiver, band status monitor by scope display, various filter settings, interference reduction function etc., can be easily set from PC, and possible to perform comfortable communication.
