More Tecsun S-8800 hidden features/adjustments

Many thanks to SWLing Post contributor, Dan Robinson, who has recently been in touch with Anna at Anon-Co and discovered a few Tecsun S-8800 hidden features we haven’t mentioned in the past.

Anna notes:

There are some hidden features for this model that are worth mentioning, and are available on all S-8800 radios, also the pre-2021 ones.

Backlight setting

In power-off mode, press and hold [ 2 ] on the remote until the display shows “ON” or “Off”, this to change the backlight setting to always-on or auto-off. In the auto-off setting the backlight turns on after pressing a button or using a tuning knob, and turns off automatically after a few seconds.

DNR (Dynamic Noise Reduction

In the AM band (LW, MW, SW), first press and hold [ 4 ] on the remote to activate the possibility of this feature. The display will show “ON” or “Off”. Make sure that it is turned on. Subsequently, press and hold [ 6 ] on the remote until the display shows “ON” (DNR activated) or “OFF” (DNR deactivated).

FM De-emphasis Time Constant

While receiving FM broadcasts, long press [ 5 ] on the remote to adjust the de-emphasis setting to 50?s or 75?s.

Adjusting the signal indicator sensitivity:

1. Enter FM, LW, MW or SW band

2. Select a weak station.

3. Press [ 7 ] on the remote for about 0.5 seconds.

4. Rotate the main tuning knob immediately to adjust the bars of the signal indicator.

5. Press any button for confirmation or auto save after 2 seconds.

While making the adjustment in step 4, the value in the top-right corner of the screen changes. The factory default value is supposedly around “6” for FM and SW: 6, and around 16 for MW. The adjustment range is -99 – 99.

Add Seconds to the Clock

With the device turned off, press and hold [ 8 ] on the remote to add seconds to the clock. Press and hold [ 8 ] again to hide the seconds from the clock.

Adjust the FM soft muting threshold

While in FM, press and hold [ 9 ] on the remote for about 2 seconds until the current level (probably around level 5) appears in the main display area. Then adjust it by rotating the tuning knob and then press [ 9 ] again to confirm the setting.

Many thanks to Dan and Anna for sharing these tips!

BBC Radio Stations Broadcasting Re-Tune Instructions

Many thanks to SWLing Post contributor, Bill Hemphill (WD9EQD), who writes:

Hi Thomas,

The BBC in their transition to digital radio has started closing some of their AM radio stations.

See following link:

https://www.bbc.co.uk/reception/work-warning/news/mw-closures-2021

The AM stations being closed are broadcasting “Re-Tune” instructions on their frequencies.

Not sure how long they will be doing this. The “Re-Tune” messages are interesting.

I have used the G4DYA KiwiSDR web receiver to listen and record some of the “Re-Tune” messages.

Most are just straight forward instructions, but Radio Hereford-Worcester on 738 has recorded individual

messages by several of their on-air personalities. The messages just loop continuously.

Attached are MP3 files for 738 Radio Hereford-Worcester, 1035 Radio Sheffield, 1341 Radio Ulster and 1503 Radio Stoke.

Zack’s Sony ICF-S5W

In reply to our Caveat Emptor post, many thanks to SWLing Post contributor, Zack (N8FNR), who writes:

Attached is a copy of the Sony brochure for the ICF-S5W, a photo of the front and also the inside. This is a fairly old rare radio and some of your readers might enjoy the following.

I just wrote to Dr. Vlado asking if he can restore my fairly rare Sony ICF-S5W. Luckily I have three of them, two of which are dead so I could send all three and he could possibly cannibalize them to make one good working rig. I also have an original copy of the manual.

Few people have heard of the ICF-S5W as it was only made from 1980-81. One of the interesting features of the radio is that the Sony engineers put the 16cm ferrite antenna at an angle as they claimed it improved incoming signals.

Many reviewers at the time claimed that it was better than the GE Superradio of that vintage.

If you would like to know more about this radio below are a few reviews.

Thank you for sharing this, Zack. I was not familiar with the Sony ICF-S5W. I love the simplicity of this radio–and that nearly diagonal ferrite bar? I can’t think of any other radio I’ve seen with that!

And having spare “parts” radios is a solid plan if you have a particular radio you love and want to keep it in working order over the long term.

Any other ICF-S5W owners out there? Please comment!

Radio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

CQ CQ CQ IE —Holy Broadcasting from Ireland and Northern Ireland (DXing.info)

European DX listeners have recently discovered a wonderful new target. On 27 MHz it is possible to receive Catholic mass celebrations from Ireland and Northern Ireland. Hundreds of local churches around the island are broadcasting holy masses live. If you tune in between 27000 and 28000 kHz, you might be able to hear many interesting churches. The transmitter power is usually only 3 watts, so a strong F2 opening is needed. Luckily with the current solar maximum this happens quite often.

How did all this start? This is a fascinating story, told by a Father, who has been helping the idea to become reality.

The broadcasting of Masses was introduced in a rural Irish diocese over 30 years ago when the resident priest was considering a way of reaching out to those who were housebound in his parish. They had access to religious broadcasts on National Radio and TV, but he knew that it was no comparison to a local broadcast. There were many incidents of families coming home from Mass on Sunday and their housebound parent or grandparent had ‘all the news’ (they were aware of all the happenings in the parish) when they arrived home.[…]

Utica man producing film about the history of radio (The Voice)

Decades before Spotify, Pandora, and even satellite radio, terrestrial (land-based) AM and FM radio reigned supreme. Many listeners, including Utica resident Ron Robinson, idolized the disc jockeys just as much as the artists they played.

Robinson, 51, is working on a documentary film entitled “Radio Dayz… The Movie,” which focuses on the history of radio, including the early days of Detroit radio. “(The film) tells the story of radio through the people who worked in radio,” he said.

Robinson interviewed several well-known radio personalities such as Paul W. Smith, Dick Purtain, Fred Jacobs, Dick Kernen, and more for the film. Robinson, who worked for WJR for 20 years before starting his own production company, has several connections in the industry. He started interviewing for the documentary in 2013.

“Most people think of radio, they think of New York, California, and Chicago, and rightfully so. But, Detroit has been an important and ground-breaking city for the medium of radio,” Robinson said.

The documentary is a chronological look at the history of radio, starting with the first radio stations. It also takes aim at the first radio “celebrity,” Fr. Charles Coughlin. The Detroit-area priest took to the airways in the 1920s and eventually garnered an audience of 30 million to his weekly radio show. Coughlin would later become a polarizing figure as World War II approached. “He’s on the wrong side of history, if you will,” Robinson said.

Improving ULR FM reception (Iberia DX)

Often I get surprised when I listen to the FM Band with my autoradio. It has no bandwidth options, no filters, but sensitivity and selectivity are much better than most of the well-know portables. Mine is inserted into the Skoda console so I have no way to know who manufactured it, the brand/model or its tech specifications. Most of the times I wonder why other portable firmwares does not include, for instance, similar choices like the high speed decoding RDS info. Then I thought… Will be my ULR Sangean DT-800 up to the task?

An autoradio like mine (SKODA Spaceback car) decodes RDS and hears weak signals at once. It is part of a well balanced system: receiver-feedline and rubber antenna on the metallic car roof. My pocket ultralight radios use the earphone cable as an aerial, so even being very good receivers, the antenna is far to be reliable with tricky and changing reception as it depends on the cable position at every moment. Uhmmm! I needed to find a better way to listen using my small toys.

In the shack I had some whips with male BNC and PL-359 connectors, but the Pocket ULR has a 3,5 mm female plug-in, so I found a “female BNC > male jack 3,5 mm” adapter and connected the whip. I chose a telescopic antenna 20/115 cm long folded/unfolded to test the Sangean DT-800T versus the SKODA autoradio, focused on the BOTB from 87,5 to 91,5 MHz. When a long whip is used some unwanted effects come into the scene. The first is related with audio; connecting the whip the sound must be heard via the small speaker so don’t forget to choose a quiet environment not to miss weak stations. The second one is pure physics; due to the whip length, the ULR 3,5 mm female plug-in gets extra strain and that could damage the inner weldings, so extra care must be kept in mind at any time.[]

UsedRadioMall.com

Many thanks to SWLing Post contributor, Matt, who shares a link to a radio classifieds site he has created. Check it out!

The UsedRadioMall.com web site lists radios and items related to the subject of radio. The list may include receivers, transmitters, transceivers, amplifiers, antennas, parts, and components related to amateur radio, two-way radio, cb radio, broadcasting, recording, production, and hi-fi.

Introduction
Changes in ionospheric electron density caused by space weather and diurnal solar changes are known to cause Doppler shifts on HF ray paths. For example, see Figure 7 in Boitman et al., 1999. As part of the WWV centennial, 50 stations collected Doppler shift data for the original Festival of Frequency Measurement, demonstrating the value of volunteer participation in collecting this data. This June, we request that all amateur radio stations, shortwave listeners, and others capable of making high-quality HF frequency measurements help us collect frequency data for the June 10 annular eclipse. Researchers will use the crowdsourced data to investigate the superimposed effects of auroral particle precipitation and the eclipse on Doppler shift.

All you need to collect data is an HF rig connected to a computer running open-source software. A precision frequency standard, such as a GPS-disciplined oscillator, is desired but not required to participate. All ham operators and shortwave listeners around the globe are invited to join in, even if your station is far from the path of totality. Last year’s eclipse festivals included over 100 participants from 45 countries. The experiment will run from 7-12 June. All participants will receive QSL certificates and updates as the data is processed. This is a pilot experiment for HamSCI’s Personal Space Weather Station project, which seeks to develop a global network monitoring the geospace environment.

Videos: Nick explores synchronous detection and the Racal 6217

Many thanks to SWLing Post contributor, Nick Boras, who shares the following:

I was motivated by one of Tom Styles videos (hamrad88) about Sync detection to make one of my own. It is no secret that Tecsun offers Sync on several of their radios but only the 660 and 680 really work. My take on Sync is that the results are not consistent even on some of the highest rated Sync radios. While my video is not scientific or nearly complete, I think it gives a good representation of what we can expect from Sync for SWL.

[In addition] today was Radio Day, so I made another video on a very interesting radio:

Thought your readers might be interested.

We are indeed! Thank you for sharing these videos, Nick! That Racal, by the way, is a beautiful beast of a rig!

SDRplay’s article regarding counterfeit products and how to avoid them

A fake SDRplay RSP1A on Walmart.com

SDRplay recently posted this article which focuses on counterfeit products. It’s a worthy read.

They’ve seen an uptick of people contacting them believing they’ve purchased a genuine SDRplay SDR only to discover it’s a counterfeit and will not work with new SDR Uno releases.

As I’ve mentioned before: I’m not a fan of counterfeits and will not knowingly link to them on this site.

The problem with fake products is that they’re not supported by the original manufacturer and often don’t perform up to the same specifications. The price difference is negligible–sometimes fakes are even higher than the genuine article (see the ad at the top of the page as a case in point). I feel like any money saved is a moot point when counterfeit product can’t take advantage of firmware upgrades and RF performance isn’t tested and verified.

It’s best to purchase either directly from the manufacturer or their authorized dealers.

Also, when you purchase the genuine item, you’re supporting the innovators in our radio world. Companies like SDRplay, AirSpy, and ELAD–original SDR manufacturers–are always seeking a means to get the best performance and functionality out of their products. They do meaningful research and development and implement customer feedback in each product iteration.  Fake products do not: they merely copy and sell. They have no R&D department. Their quality control is all over the place.

When purchasing a new SDR–or any product for that matter–I encourage you to buy the real deal, Not only will you have product support in the long run, but you’ll also be investing in the innovators of our radio world.
