| Muzen Audio handcrafted radios
Posted: 10 Jan 2017 04:37 PM PST
 Many thanks to SWLing Post contributor, John Figliozzi, who writes:
This [company] was mentioned in regard to the CES show out in Las Vegas:
http://ift.tt/2iD13nA
It’s a Chinese company with a rather novel approach to the design of modern radios � AM/FM/Internet Bluetooth, along with the use of tube aamplifiers in some models. The web site is almost all in Chinese but the pictures are cool.
Air Smart Audio is the parent company; Muzen Audio the subsidiary.
John also shared the following item from Radio World:
Muzen Audio Group’s founder Dejun Zeng, referred to as the “Father of the Tube Amplifier” in China, is looking forward to the new challenge, saying in a statement: “It is my greatest desire to build a legacy with this organization that will lead customers to say, ‘I am proud to have a Muzen radio.’”
The company received a 2017 CES Innovation Award for their new AM/FM/internet radio and Bluetooth speaker lines, the fifth CES Innovation Award received by Zeng. Muzen Audio also designs a series of vintage-style tube amplifier radios and what the company calls “on-the-road” radios.
(Source: Air Smart Audio)
Thank you, John!
From what I gather, Muzen radios are very much “boutique” radios, thus come with a “boutique” price tag�some models costing as much ass $500 US.
Still: it’s refreshing to see a Chinese radio manufacturer marching to their own beat, making handcrafted products in small batches.
According to Twice.com, Muzen recently introduced the “Classic 1” AM/FM radio with Bluetooth speaker that is powered by a “fluorescent display tube amplifier.” Twice notes:
The Classic 1 is handmade and crafted with real rosewood, and every unit comes with a unique code verifying its hand craftsmanship.
Frequency response of the speaker is 75Hz to 16KHz, of the amplifier, 30Hz to 20KHz.
Pricing and availability will be announced during CES 2017.
I’m looking forward to learning more about Muzen radios! I do love the designs.

Post readers: Anyone familiar with Muzen Audio or own one of their products? Please comment!

HF and solar conditions continue to decline
Steve G0KYA has now updated his hourly HF propagation charts for the UK for the next three months.
The charts, with real-time solar information, can be found at http://ift.tt/2iBwfDY
Steve, who helps produce the weekly HF content for the RSGB’s GB2RS propagation report, says: “You can definitely see the effects of the current poor solar conditions. As the charts are produced by VOACAP it is suggested we use the smoothed sunspot number (SSN) for the calculations.
“In January 2016 the SSN was 44.8, but this month it is just 29.2. In fact, the actual daily sunspot number is even lower than this at around zero to 11 with a solar flux index in the low 70s.
“Given that at sunspot minimum we wouldn’t expect the solar flux index to drop below 66 you can see that we are very close to the kind of conditions we can expect over the next few years.
“NASA says the current sunspot cycle is the smallest since cycle 14, which had a maximum smoothed sunspot number of 107.2 in February of 1906.
“The current prediction for sunspot cycle 24 (this one) gives a smoothed sunspot number maximum of about 101 in late 2013.
“The next sunspot minimum is currently predicted to occur around 2019-2020. The solar maximum for cycle 25 is predicted to be around 2025, possibly with a monthly smoothed maximum sunspot number of around 60-65. If true, this is almost down to Dalton Minimum levels.
“What we are seeing is that the ionosphere is currently struggling to regularly open up to DX at frequencies much higher than about 18MHz. Around the UK we are even finding 40m (7MHz) closing to inter-G contacts by early afternoon, if it opens at all.
“This means that 80m (3.5MHz) and 60m (5MHz) are coming into their own, although both are struggling with inter-G contacts by late afternoon.
“A succession of coronal holes and their associated high-speed solar wind streams are also causing disruption to the ionosphere. While these are typical of this point in the sunspot cycle they are generally not helping DX at all.
“This week’s high K indices have been caused by such a hole, although the solar wind has mostly had a north-facing Bz field, which is less likely to couple with the Earth’s magnetic field, and we have’t seen the very high K indices that indicate severe auroral conditions.
“Lastly, readers might be interested in a new HF propagation tool based on the ITU’s ITURHFPROP software and developed by Gwyn G4FKH. The URL is http://www.predtest.uk
“The ‘Area Coverage’ predictions have been available for some time, but a new Point-to-Point prediction tool is now available. Clicking on the link starts the process, when the form is filled out a series of plots are available depicting propagation between the required Tx. and Rx. sites.
“New features include various colour schemes for the plots allowing users with colour preferences to make the best viewing choice for themselves.”

RSGB PSC Chairman

The station has apparently been transmitting their exact latitude and longitude as part of the image.
Although an IARU Region 1 publication, this issue has a report by Lou VK5EEE giving his opinion about the “empty” ham bands in Australia.

Testing HF antennas
Testing HF antennas is a tricky thing to do. Simple on-air test are seldom conclusive and are more often than not, they are just plain confusing. SOTABEAMS has come up with a completely new way to test antennas, locations and to monitor propagation using the WSPR system.
SOTABEAMS system consists of two parts; WSPRlite a WSPR beacon with electronic power control and DXplorer.net a data analysis website.
WSPRlite sends a test transmission which is received by hundreds of stations across the world. DXplorer.net is a web based system that gathers these reports and presents them in a whole new way, allowing the user to check the DX performance of their antenna system. However, the real break-though is the ability to compare systems in real time and all over the world. DXplorer.net does this in a simple and intuitive way enabling you to see what difference changes to your antenna system really make to its DX performance.
More information on WSPRlite and DXplorer.net is available at:

| Talking scanners�
Posted: 09 Jan 2017 03:52 PM PST
 Since I was a kid, I’ve always enjoyed listening to police, fire, public services/utilities, and aviation communications on scanners. Growing up, my father had a Regency Executive scanner in our living room, and he used it to listen to all of the local action before it was published in the newspaper the following morning. All so fascinating to a kid like me, listening in. Ah, those were the days�!
Regency Executive Scanner (Image source: eBay)
The Regency scanner was populated with crystals, and I fondly remember accompanying my father to our local radio shop to purchase new crystals for various frequencies. My father still has and uses this scanner today��evidently, a few of our hometown services still usse the samee frequencies they used back in the 1970s.
But oh, how times have changed
As the years have passed, public services moved to more complex communications systems including trunking, and now a host of digital modes have come to the fore, some even encrypted.
My interest in scanner technology frankly waned during the 1990s. I suppose this had to do with the amount of travel and moving I was doing at the time. In the 1990s, for example, I lived in at least seven different communities in two countries. Between 2000-2010, I lived in five different communities in three different countries. I always remained dedicated to shortwave radio, of course, because while frequencies changed, I could receive many stations in Europe that I could also receive in North America. I knew that scanner frequencies, by their very nature, vary community-to-community, so I didn’t bother.
Truth is, I simply lacked the patience to program (relatively complicated) scanners. Not to mention, I was really put off by the idea of traveling with a scanner, thus requiring a thick frequency guide just to hear local services.
Welcome to 2017
I n the past few years, technology has made a big leap forward in the scanner world. With robust on-board memory, GPS capabilities, and dynamic frequency databases searchable by postal code and/or GPS coordinates, keeping an up-to-date scanner is now a great deal easier��brilliant developments for a scanner newbie le like me!
So, exactly why do I want a scanner all of a sudden? I mainly want one to keep in the messenger bag I carry with me everywhere. I’d like something to take on travels, perhaps help me listen in on traffic problems or simply eavesdrop on the local public service scene to understand what’s happening around me. Moreover, I find I love listening to aviation frequencies! And though I travel with other radios, the ability to tune NOAA frequencies would be super, too.
I started thinking about scanners last year when we experienced a forest fire in our community. We discovered the fire as we traveled home that day, and found our local road blocked to traffic for about an hour as emergency vehicles moved in. Fortunately, I carry a Yaesu VX-3R in my messenger pack and was able to find the frequencies the fire department was using to communicate with the fire-spotting plane circling overhead. It gave me some measure of comfort to hear that things were almost contained at under twenty acres. In truth, many of us were thinking through a possible evacuation scenario since, at the time, massive forest fires were flaring in various parts of the state.
So, here’s my question to readers in-the-know regarding scanners: can you help me find the perfect scanner for the following requirements�?
- Handheld (not mobile/base)
- >Easy to program
- GPS capability
- Updated frequency databases that can be stored internally
- Able to receive as many analog and digital modes as possible
- Relatively durable and compact
- Long runtime on batteries
A friend recommended the Bearcat/Uniden BCD436HP, a scanner that seems to have a lot of the functionality I seek.
I know that Uniden Homepatrol II is also recommended by many.
Also, the Whistler company has a number of scanners and a large following, as well.
Hmm�So many choices!
Post readerrs, can you help me out? What sort of scanner do you recommend, and why?

| Klaus demonstrates his folding mag loop antenna
Posted: 09 Jan 2017 03:52 PM PST
Many thanks to SWLing Post contributor, Klaus Boecker, who follows up after our recent post showcasing his homebrew magnetic loop antenna.
One of the cool things about Klaus’ antenna is that he can easily position it vertically (see above), or fold it over into a horizontal position (see below).
While one would think Klaus would get optimal performance from his loop while vertically-oriented, it’s not always the case. Klaus has discovered that on some frequencies, placing the antenna in the horizontal position lowers the noise level and increases the target signal’s strength.
To demonstrate, Klaus made the following short video for us:
Click here to view on YouTube.
That’s a pretty amazing difference, Klaus! I’m no antenna expert, but perhaps what’s happening is you’re eliminating noise that is polarized in the plane of your antenna, thus the signal “pops out” much better when oriented horizontally?
I’m curious if any readers can explain this. I know very little about loop antennas�especially smmall loops since so much of their surroundings affect their performance.
Thanks for sharing, Klaus!

| Oxford Shortwave Log: Sony ICF-SW77 vs ICF-SW55 vs Tecsun PL-310ET
Posted: 09 Jan 2017 01:42 PM PST
 Hi there, I recently posted an article regarding a couple of recent DX catches with the Sony ICF-SW77 receiver and went on to explain the background to a multi-receiver test I had started conducting, comparing it with its stablemate of the time the ICF-SW55 and, just for the hell of it, a more modern, yet modest portable in the shape of the brilliant little Tecsun PL-310ET. Sony ICF-SW77
The initial results confirmed the performance of the Sony receivers to be very similar and thus the justification for the original price delta of £100 in the UK to remain in question. The first target signals chosen and in the original post were ABC Northern Territories on 4835 kHz and Radio Mali on 9635 kHz.
  Sony ICF-SW55 Tecsun PL-310ET
The initial results reinforced my view that the PL-310ET is a great portable for relatively small money; it managed to copy both signals, something you might not expect from what is essentially a budget receiver.
Below are links to the next 6 reception videos on the Oxford Shortwave Log YouTube channel and once again, featuring all three radios. I have used two different antennas during the testing � a 75 metre longgwire and the Wellbrook ALA1530 active loop, running on batteries. The accompanying text description to the videos indicates which antenna was used.
Although the PL-310ET clearly struggled with the more ‘hard-core’ DX signals amongst those detailed below, the fact is, for less than £40 in the UK (and I’m certain even less elsewhere), Tecsun have delivered us a portable radio that really is capable of real DX. With DSP, a number of audio bandwidth filter options and great sensitivity, it’s a winner for beginners to DXing and to ‘old hands’ who want a radio in their pocket when they take the dog for a walk for example (something I do all the time � you never knoow when you’re going to come across the next barbed wire fence!). As for the Sonys, well I’m still not convinced one way or the other that the £100 price delta on the original price of the ICF-SW77 was worth the money � the ICF-SW55 is pretty close to it in terms of delivvering discernible audio across all of the below reception videos. I’d be interested in your views and note there will be a final posting on this 3-way receiver comparison to wrap things up. In the meantime, thanks for reading/watching/listening and I wish you good DX!
Enbedded videos follow below.

| Lennart reflects on Radio St. Helena Day history
Posted: 10 Jan 2017 06:22 AM PST
 Many thanks to SWLing Post contributor, Lennart Weirell, who shares the following:
Some Radio St. Helena History
The idea to put St. Helena on the shortwave map came up in conjunction with the preparations for the Nordic Championships in DX-ing in 1990 arranged by Stora Tuna DX-klubb.
The two Swedish dx-ers Jan Tunér and John Ekwall wanted to add a special station into the competition. John was also the person behind the shortwave transmission from Radio Syd in Gambia in 1984.
The first shortwave transmission from St. Helena took place in the evening of 1990-10-06. I participated myself in the competition, but I did not manage to hear the station at that time. The response for the Radio St Helena was so good that they decided to continue once a year with what was known as Radio St. Helena Day.
In 1993 I managed to hear the station and I got it verified.
 
More about Radio St Helena can be found at http://ift.tt/2icaNnN
Lennart also included scans of Radio St. Helena’s 1993 newsletter (click on each page to enlarge).
 
Thank you for sharing this with us, Lennart. Honestly, much of these hidden, fascinating bits of radio history would be lost and forgotten if it weren’t for folks like you and our other contributors who share them with the world!

| Minimal Change in Latest Australian Radiofrequency Spectrum Plan:
Posted: 10 Jan 2017 04:22 AM PST
eHam.net News � The llatest Australian Radiofrequency Spectrum Plan � ARSP 2017 �— was published on the Australian Communications and Media Authority’s (ACMA) website on 3 January 2017. It was registered by the ACMA on 20 December 2016 and came into effect the next day, with a commencement date of 1 January 2017. Only minimal changes have been made to the previous Spectrum Plan, principally those arising from the outcomes of the 2015 World Radiocommunication Conference � WRC-15. Most of the updates involve chhanges to Footnotes relating to specific allocations, while relatively few comprise changes to allocations. Of chief interest to Australian amateurs is the addition of the allocation of a 15 kHz band for the Amateur Service at 5351.5-5366.5 kHz, now widely known as the 60 metre band. This was approved at WRC-15 as a word-wide Amateur band. The WRC set different maximum radiated power specifications applying in different regions and countries, ranging from 15 watts effective isotropic radiated power (eirp) to 25 W eirp. Specifying ‘eirp’ takes account of the efficiency of different antenna systems, which can be rather inefficient at these frequencies. In Australia, Footnote 133B in the Spectrum Plan specifies 15 W eirp. The only other update to the Spectrum Plan of interest to amateurs is the addition of Radiolocation as a primary service in the 77.5-78 GHz band. The Amateur and Amateur-satellite services are also primary in this band. The new primary service is limited to short-range radar for ground-based applications, including automotive radar, according to the updated Footnote, no. 559B. Sharing studies conducted for the ITU over recent years demonstrated that the two services could reasonably co-exist as primary allocations.
