Earlier today, I published a Guest Post from SWLing Post contributor, Troy Riedel. Somehow, while wrangling with embedded table code, I managed to delete nearly half of his post prior to publishing and heading into town for the day.
I’ve just corrected his post which now includes all of his comparison videos and his conclusion.
Many thanks to SWLing Post contributor, Troy Riedel, for producing this excellent comparison of the Tecsun S-8800 and Grundig Field BT “lunchbox” radios:
The Lunchbox Showdown
by Troy Riedel
I have been watching with interest all of the information & reviews of the new Tecsun S-8800. Frankly, I was especially interested in how it would compare with the other “lunchbox” SW radio – the Eton Grundig Edition Field BT (the Digitech AR-1748 lunchbox radio is also available in AUS for approximately $207US shipped). As I contemplated which lunchbox to purchase, I put together the following Excel comparison table of the S-8800 vs. the Eton Field BT to assist me in making my decision:

Yes, the S-8800 without a doubt has more features than the Field BT. However, the S-8800 is slightly more than twice the price of the Field BT ($268 vs. $130)! Does the performance of the S-8800 equate proportional to the price difference?
Shortly after I made my Excel comparison table, Thomas published video comparisons of the S-8800. I very much appreciated the review and video comparisons that pitted the S-8800 against several popular portables. It gave me a baseline to set my expectations. However, those videos didn’t answer my question: “should I purchase the S-8800 or the Field BT”?
I contacted Thomas and I told him “we need an S-8800 vs. Eton Field BT” video comparison so SWL’ers have a true lunchbox vs. lunchbox comparison! I volunteered to purchase an Eton Field BT and have it delivered to Thomas for him to compare the two (after which he would forward the Field BT to me). After he hesitated, I replied: “what if I buy the Eton and we meet in North Carolina to compare them together”? Fortunately Thomas readily agreed and I made the 6.5-hour journey from Southeast VA to Mount Mitchell State Park for the Lunchbox Showdown (864-miles roundtrip on my odometer)!
Thomas and I had a limited amount of time. I arrived at noon. Thomas and I had 8-hours … and that included time for Thomas’ Parks On The Air (POTA) Activation, our S-8800 vs. Field BT comparison, we had to eat (it was a long drive for me!), and Thomas brought many other toys so we had to carve out time to “play radio” (and I can’t drive 400+ miles to Mount Mitchell and not walk to the summit of the highest point east of the Mississippi River!).
Luckily conditions were as ideal as I have ever seen them (evidenced by the fact Thomas made contacts from TX to the Azores with his Elecraft KX2). So please keep in mind, what follows is in no way a complete comparison. And to be clear, it was never my intention to review either receiver (there are many people more competent than I am that have already done this – Thomas among them!).
My interest re: these two models is primarily limited to each’s shortwave performance (I use a Sangean PR-D15 and a Grundig YB400 for AM DX, I prefer my Sangean PR-D15 for FM and I own 12 shortwave receivers). Thus our goals were to find and compare multiple representative SW signals. Thomas is obviously familiar with local AM stations in the area that he uses in his comparisons, thus we sought out a few AM signals (I recorded one to illustrate one huge difference that we both perceived in the two radios). Due to time, hunger, and eventually darkness we had to call it a day at 8 P.M.
I used my iPhone 6S to record the following comparisons. This was the first time I recorded shortwave signals. In retrospect, I wish I had made the recordings longer but at the time I was unsure of how much memory each recording would used, how much time it would take to upload, etc., so I kept everything at 1-2 minutes. As you will see, I recorded nearly all of the signals with the backlight off. You’ll see me reaching in, on Shootout 5, to tune off frequency – then back on – simply to show how the backlight would/or would not affect the weak signal on the Field BT (you’ll also see that it’s harder, outdoors, to read the Eton display without the backlight vs. the clearer Tecsun S-8880).
The Eton Field BT has its own SW RF Gain (a huge bonus) and you will see me reach into the field of view once or twice to fine tune the Field BT on weaker signals. And if you’ve studied my comparison table, you’ll see that the S-8800 has multiple bandwidth choices whereas the Field BT only has Wide & Narrow settings.
You will see me occasionally change the BW on both. I preferred not to speak during the videos as not to mask the audio of the signal thus I will set-up the specifics of each video with each individual link to my new YouTube Channel, SW Hobbyist, that I set-up to host these (and hopefully many future SW-related videos to include radio recordings & antenna comparisons).
Thomas and I both felt that the AGC of the Tecsun S-8800 was very slightly better (more stable – absolutely no “chug”) than the Eton Field BT (again, a very subtle difference). We both liked the sound of the Eton Field BT much better – it was crisp, full and just seemed to “pop” through its grill (see Shootout #7). The huge thing we both disliked with the Eton Field BT is its tuning dial. Yes, it has Q-Tune so one can jump from 5000, 6000, 7000, etc., with the push of a button but the tuning dial (even in “Fast” mode) is painfully slow and deliberate (dare I say horrible in comparison to the S-8880?). We both love the fact the S-8800 has a remote. But even without the remote, the S-8800 was much more pleasurable to manually tune.
Not to speak for Thomas, but I believe we generally felt [overall] that the SW signals were essentially close enough to call even … the edge to the Tecsun on a couple and the edge to the Field BT on a couple of others (I specifically remember us both commenting on an Arabic language broadcast from Radio Saudi Arabia where we both felt the Field BT was a very clear winner – that was one of the signals that I did not record). The better “sound” of the Field BT’s speaker may have influenced our opinions – a sound that was markedly better on FM, better on AM, but a sound that was much closer on SW.
My final thoughts and conclusion: Radios are like vehicles. No one vehicle is best for everyone. Each vehicle has a specific purpose and each has a subset of features. I own a large travel trailer. I need and thus own a heavy-duty diesel truck to tow it. But I surely wouldn’t recommend my vehicle to somebody who only needs a commuter vehicle. That’s why we have everything from SmartCars, to sedans, to SUVs, to dually diesel trucks. The same goes for radios. Some people will absolutely need SSB, others may demand SYNC (neither of these units has this feature!) while others may choose a radio based on size (compact for travel or larger models with a large, easy-to-read display for desk or tabletop use). Until now, I felt the video comparisons we had for the S-8880 were comparing a truck to an SUV to a sedan. At least now we have a few videos of two lunchbox radios compared side-by-side. True, one (the S-8800) is fully loaded (in vehicle terms: a 4×4 with a touchscreen GPS and DVD entertainment system). But not everyone who requires a truck needs a 4×4 with GPS and DVD entertainment system. Some truck owners prefer the smoother ride from a 4×2 truck. I think that’s the best way to describe these lunchbox receivers.
Am I glad that I bought the Eton Field BT? For me – despite the cumbersome tuning of the Field BT – I feel the S-8800 is not worth 2x the price of the Eton (I got an even sweeter deal for my new, sealed box Field BT off eBay that was well under the $129.99 street price). But you can make your own decision, you can decide which features are must-have, and you can listen to these videos as well as the other videos that Thomas has already posted and determine if one of these lunchbox models are in your future. And because I learned so much regarding the video recording of shortwave signals (I suffered from tunnel vision while recording – not fully aware of what I caught and what I missed), I hope I can meet-up with Thomas again so I can do a better, more thorough job with a “Lunchbox Comparison, Deuxième Partie” (that French was for Thomas – I hope I got that correct!).
Thanks for putting together this comparison, Troy! It was great hanging with you last week on Mt. Mitchell!
If you’re shopping for either of these radios, you have a few options:
The Tecsun S-8800 is only available worldwide via Anon-Co at time of posting. Eventually, they will begin appearing on eBay. There are retailers in Australia and Europe also selling the model (Important: make sure you’re ordering a model from the latest production run which solves the DSP birdie problem in early units).
Many thanks to SWLing Post sponsor, Bob Raymond with DXtreme Software, for sharing the following press release:
Product Announcement: DXtreme Monitor Log 11™
DXtreme Software™ has released a new version of its popular logging program for radio monitoring enthusiasts: DXtreme Monitor Log 11.
Monitor Log 11 lets listeners and DXers log the stations they’ve heard using advanced features that can enhance their monitoring experience.
Finding Broadcast Stations to Monitor
The Schedule Checker™ lets users import schedules from Aoki, EiBi, and FCC AM web sites and display schedule data according to the filter criteria they specify. A list box lets users switch between schedule types, and depending on the schedule type selected, users can filter schedule information by band, frequency, station, country, city, state, time of day, language, antenna direction, and target area.
When the What’s On Now? function is activated, the schedule refreshes automatically at the top of each hour for Aoki and EiBi schedules.
For each schedule item, Schedule Checker queries the Monitor Log 11 database to let users know – through user-defined, foreground and background display colors – whether they need to monitor a station for a brand-new or verified country. Schedule Checker also displays bearing and distance, runs optional Afreet Ham CAP1 propagation predictions, draws optional Afreet DX Atlas2 azimuth plots, tunes supported radios to schedule frequencies when users double-click schedule items3 4 5, and starts log entries for scheduled stations monitored.
Finding Amateur Radio Stations to Monitor
Monitor Log 11 integrates with optional Afreet Band Master6 to let users see, on its graphical interface, where hams are operating. Monitor Log 11 supplies Band Master with an Entity Needed List based on the user’s Monitor Log database, making it possible for Band Master to indicate the stations whose entities (countries) users need to monitor. When invoking Band Master, users can select an Entity Needed List for all bands or individually for the 160- through 6-Meter bands.
Finding Utility Stations to Monitor
A Links menu provides convenient access to user-specified blogs and web sites that can inform users as to where utility and other stations may be operating.
Logging Stations
Monitor Log 11 lets users log all kinds of stations — radio stations, television stations, broadcast stations, Amateur Radio stations, utility stations, military stations, and more! And it lets them log stations across the radio spectrum — from long wave, to medium wave, to short wave, and beyond.
The Last Log Entries Grid on the Monitor Log window shows up to 5000 of the most recent log entries added. Its records can be sorted, and double-clicking records displays detailed data on the Monitor Log window. Users can resize the grid columns and scroll horizontally to columns that do not appear initially. And because the names of stations and NASWA countries can be quite long, users can also display a larger, resizable Last Log Entries window. A Properties window lets users change the order of columns, the number of log entries to display, and the font and color attributes of grids and other program components, such as the Content Editor for describing the content monitored, the Script Editor for creating and editing scripts, the Direct Tune interface for tuning radios, and the Comments tab for typing ad hoc comments.
Reporting Reception
Users can create customized paper and e-mail reception reports for sending to stations plus club report entries for reporting catches to clubs and magazines.
When users add or display a log entry, Monitor Log 11 prepares a post announcing their DX catch and displays it on the Social Media Post tab. From there, users can drag the post to their favorite social media web sites to share their catch with others.
Using the Script Editor window, users can create and edit scripts that format reception reports, eReports, and social media posts to their liking. The software prompts users to select the script they want to use. Dozens of scripts come with Monitor Log 11.
Users can also print SWL and Address labels on industry-standard label stock, and send eQSL requests to hams automatically through the popular www.eQSL.cc site.
Imaging
Improv Imaging™ lets users associate ad hoc images with log entries using Capture, Scan, and Clipboard functions. Captures of stations received on digital applications, waterfall displays, facsimile and Amateur TV pictures are popular. The Improv Imaging tab and Application let users view images anytime, and an Improv Image Explorer lets them peruse their entire collection and display associated log entries.
QSL Imaging™ functions the same as Improv Imaging, but specializes in associating QSL cards and eQSLs with log entries.
Other Features
Rig Control — Retrieves the frequency and mode from supported radios and permits tuning from the Schedule Checker and Direct Tune interface. Rig control is provided through integration with Afreet Omni-Rig and the SDR applications listed on our web site, currently HDSDR4 (High Definition Software Defined Radio) and SDR Console5.
Audio Archiving — An embedded Audio facility lets users maintain an audio archive of stations heard.
Reporting — Produces Performance, Stations, and Log Entry reports that track the performance and progress of the user’s monitoring station. The software lets users FTP those reports to user-provided Web space for remote access. Some reports integrate with Afreet DX Atlas to generate pin maps.
Documentation — Context-sensitive Procedural Help, Field Help, and Microhelp are accessible per window to provide instructions quickly. A web-based Information Center is accessible from the Help menu for late-breaking assistance, and Installation Instructions and a Getting Started Guide are delivered in PDF format with the software.
Operating Systems, Pricing, Contact Information

International Day for Disaster Reduction 13th October
On Friday 13th October, the United Nations Office for Disaster Risk
Reduction, explores how communities around the world are reducing their
exposure to disasters. In a recent blog “When digital is more than
just radio”, the DRM Chair, Ruxandra Obreja, outlined the considerable
benefits to be realised if Governments and manufacturers were to fully
exploit the emergency warning feature embedded in DRM and digital
radio technology. Read more.
From its infancy since 1920s shortwave radio has been associated with its potential of being a communication tool in emergencies. This use of shortwave radio is still very much present among amateur radio enthusiasts for example, who discovered its long distance properties early in the twentieth century. Amateur radio provides a means of communication on shortwaves and other frequencies “when all else fails”. This role of amateur radio is well recognised, valued and appreciated both by the public and by the world institutions managing and regulating the use of the radio spectrum.
In contrast the huge technical potential of international shortwave broadcasting that operates transmitter facilities tens, or hundred times, more powerful than those of amateur radio, remains almost unused in emergencies. At the moment when local and even regional communication and information networks are needed most, they are destroyed or overloaded and the population suffers from an information blackout. Shortwave radio is capable of remaining the only source of information.
Although the life-saving role of radio broadcasting is widely recognised by the public, and confirmed by surveys conducted after the recent disasters – and even acknowledged by world leaders – no concrete projects have been ever designed and no regulatory framework has been developed.
That is why the HFCC – International Broadcasting Delivery in co-operation with the Arab States and Asia-Pacific broadcasting unions are working on an International Radio for Disaster Relief (IRDR) project that is based on the system of online co-ordination of frequencies managed by the HFCC in accordance with International Radio Regulations.
The HFCC is aware of the humanitarian aspects of international broadcasting. It pointed out in 2012 – as the UNESCO partner for the preparation of the World Radio Day – that terrestrial shortwave radio in particular is still considered as a powerful communication and information tool during emergency situations. Read more >>
Receivers are inexpensive and require no access fees. Shortwave radio is important for people living in remote and isolated regions of the world. It reaches across the digital divide to the most disadvantaged and marginalised societies. This is also in keeping with the Declaration and Action Plan of the World Summit on the Information Society.
The annual edition of the World Disasters Report of the International Red Cross and Red Crescent Societies (IFRC) issued in October 2013 stressed again that with only 6 percent of people in low-income countries using the internet in 2011 the digital divide is still stark, and access to low cost media technology is really the key.
The HFCC is a strong advocate for incorporating terrestrial broadcasting permanently on the disaster risk reduction agendas of the ITU and other UN agencies and institutions. It submitted two documents for the ITU-R Working Party 6A November 2013 meeting:
Both documents are annexes in Section 8 of the ITU-R Study Group 6 Report BT.2266 “Broadcasting for public warning, disaster mitigation and relief”. The report can be downloaded via this link.
A workshop was held during the November 2013 meeting addressing these issues. The web site of the Emergency Broadcasting Workshop can be accessed here. The web site also contains copies of all the presentations that were made at the workshop, and a Video interview with Christoph Dosch, Chairman of ITU-R Study Group 6 (Broadcasting service)
The HFCC has applied for membership in the CDAC (Communicating with Disaster Affected Communities) Network in keeping with the conclusion of the debate on emergency communication during the Bratislava B13 Conference. Read more >>
The HFCC is staying in touch with the Information and Communication Sector of the UNESCO agency on the preparation of the World Radio Days that are celebrated each year on February 13th.
Humanitarian aspects of terrestrial broadcasting were also on the agenda of the Global Kuala Lumpur conference in January 2014. Read Opening Remarks.
