Talking scanners…

17 Replies

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…!

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 use the same 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

In 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 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 readers, can you help me out? What sort of scanner do you recommend, and why?

Klaus demonstrates his folding mag loop antenna

7 Replies

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:

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 small 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

3 Replies

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 longwire 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 know 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 delivering 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!

Music copyright issue sends Bulgarian National Radio back to 1945

3 Replies

(Source: BBC via Mike Terry on the WRTH Facebook Page)

Bulgaria’s public radio broadcaster has been banned from playing millions of contemporary songs because of a row over copyright payments.

Since 1 January, state-funded Bulgarian National Radio (BNR) has been filling its airwaves with classical pieces, jazz and traditional folk music instead, the Novinite news agency reports. It’s locked in a dispute with the non-profit Musicautor organisation, which manages the rights to work by both local and international artists – 14 million pieces of music in total.

Even the traditional version of the national anthem is off-limits. Listeners tuning in on New Year’s Eve instead heard the BNR symphony orchestra and choir’s take on the tune, Balkan Insight reports, adding that the copyright row means only music made before 1945 can be played. BNR itself says it cannot play “95% of today’s modern music repertoire”.

Musicautor wants BNR to pay more in royalties – triple the amount it pays at the moment – to bring it more into line with national radio in other EU countries. But radio director Aleksander Velev says that’s impossible unless it gets more funding or drops a regional broadcast, which would “tarnish the radio’s public mission”.[…]

Many thanks to SWLing Post contributor, Mike, who shares the following from the YouTube channel The Great War.

This short video gives an excellent overview of communications methods and equipment used throughout World War I. I’ve included the video’s description below:

“If one thing was vital to the the new kind of modern warfare in the First World War, it was communications. The Industrial Revolution had brought wireless transmission of signals with it and the huge armies of World War 1 needed to be in contact constantly to be successful in the field. In this special episode we introduce you to the birth hour of modern military communication and signals.”

Thanks again, Mike! I’ll subscribe to The Great War channel on YouTube.
