Many thanks to SWLing Post contributor, Cezar Vener, who writes with the following inquiry:
I would like to ask you if you can help me with a schematic diagram for an EDUTEC 4-Band digital radio (PLL EDUTEC 4-Band Digital Radio Weltempfänger). It is not broken, but I would like to modify it. Of course, I could spend some time and manually extract the schematic, but I would lose too much time.
While I know that “EDUTEC” is a registred trade mark for technical (“non-food”) products that was sold by “Eduscho Handelsgesellschaft” in Bremen and also I found that it is now owned by Tchibo, well – I would like to kindly ask you for help in this matter? (course, if you can).
It is an old product, probably made in the 90’s and until now, I didn’t find anything on the net about it. I opened it and I found that its core is TA8132AN, and the FM section is made around TA7358AP. The audio stage is built with C1212C, and there is one more integrated circuit there, TA8148S (no datasheet on the net, but I found that is a DC-DC converter for electric tuning – built-in stabilized supply output for biasing VHF tuner variable capacitor / sine wave oscillation).
BTW, I found it also in SONY CFS-W504L 🙂
The PLL chip is soldered with the unmarked side, so I don’t know what type it is.
[See photo at top of post.]
Here is a photo of the rear back stand:
Unfortunately, there is no other model or name written on the radio.
I see there “CENTRON LABORATORIES LTD”, that points to the company with the same name from Gujarat, India. Very interesting :))
In the hope of an answer from you, please allow me to thank you and to congratulate you for the very nice site that you maintain there!
Many thanks, Cezar! It’s readers like you who make this site such a great one!
Post Readers: I hope someone may be able to help Cezar. This radio looks familiar–perhaps I’ve seen it badged with a different company name? Please comment if you can help Cezar locate a schematic.
On a side note, I suppose I should mention that I was pretty disappointed with the DE1129 because I had hopes it would make for a great all-in-one portable radio recorder for ETOW. While the DE1129 could record FM/AM and SW radio directly, it had serious problems: it auto-adjusted the volume level during recording (one could not turn off the internal speaker), it degraded audio quality in recording, and medium wave was plagued with a “ticking” sound every 10 seconds. It produced digital hash on various meter bands. My summary of the DE1129: fine concept, poor engineering. Read my full review of the first version of the DE1129 here.
The Kaito KA29: First impressions
The Kaito KA29 is a cute little portable. Mine has a black body with orange band encircling the diameter. That orange band is actually a nice addition–it helps the radio show up a bit better and makes the ports a little easier to see when lighting is low.
The overall quality of the radio feels fine: the hard plastic body has a smooth matte quality and the buttons have a very tactile response. The telescopic whip antenna is long for the overall radio size, but is still a little on the short side for good HF gain. Oddly, unlike most radios, the antenna cannot swivel at its point of attachment to the chassis; it can only be extended and tipped side-to-side–but not front to back, or back to front. Like the DE1129, the KA29 lacks a back stand–a big negative in my book–but admittedly a back stand would be of little use while SWLing with this rig because the antenna can’t be swiveled or tipped into a useful vertical position. Hm. Also like the DE1129, the KA29 uses a slim rechargeable battery pack.
When I first turned on the KA29, I thought I had received a faulty unit: I pressed and held the power button for a second, the display lit up a bright green, I released the power button…and the unit turned off. After a little trouble-shooting, I realized that the KA29 requires holding the power button a full two seconds, until the “Kaito” brand name appears on the display.
Unfortunately, the KA29 antenna does not swivel.
This sluggish power-up response is truly an indicator of most functions on the KA29. It’s as if every function is controlled by a slow processor–which I’ve no doubt is the case.
As far as I can tell, all the menu functions are the same on the Degen DE1129; obviously, they’re built on the same firmware. Indeed, Kaito is the North American brand for the Chinese manufacturer, Degen; the Degen model number for this radio is DE29. In this sense, most functions are familiar to me.
The one added feature of the KA29 that my version of the DE1129 didn’t have is a number pad, useful for direct entry of radio frequencies. I should note here that I (typically) toss the owner’s manual aside when I first get a radio, in order to test how intuitive its functions are. I spent quality time with the KA29 while traveling a few weeks ago, and as I didn’t bring the manual, I had to learn its functions via trial and error. It wasn’t until I returned that I learned how to use direct frequency entry; the is answer clearly stated in the manual: just key in the frequency, then press the appropriate band (AM/FM/SW) to go to that frequency. Pretty simple, actually. The response time for the radio to start playing the frequency you enter is only about one second.
Use of the tuning knob (located on the right side of the radio) is easy and straightforward–tuning up and down will move the needle 5 kHz steps between frequencies. Unfortunately, as on the DE1129, 5 kHz is the smallest tuning step available. The KA29 briefly mutes between frequency changes, so when tuning slowly it’s very noticeable. If you tune quickly, the KA29 will produce snippets of audio as you pass signals, but I find it often skips over even very strong signals. In short? Though I suppose it could be worse, I do not like tuning the KA29.
I should also mention that the KA29 has no adjustable bandwidth; I’m guessing the AM bandwidth is stuck at around 6 or 7 kHz.
While I no longer have the DE1129 in hand for side-by-side comparison, my impression is that performance between the two radios is very similar.
Herein lies the strength of the KA29. It obviously uses the same speaker technology (with an acoustic chamber) that the DE1129 uses. You will be favorably impressed with the audio from this wee radio–it is quite robust for a pocket radio of this size, and in a small room, almost room-filling. It sounds fantastic on FM and AM alike–you can even hear a hint of bass. One day, I tuned the KA29 to a local AM station and listened quite comfortably in another room. Impressive.
But what about receiver performance?
FM performance is quite good. I’ve used the KA29 in two different cities, and found that it could detect most of the same FM stations my other portables picked up.
I was pleasantly surprised to note the absence of the annoying ticking sound I heard in the DE1129; it appears Degen engineers have succeeded in eliminating this distraction. In general, I believe the KA29 performs acceptably on medium wave for basic local and nighttime clear channel broadcast listening. The AGC circuit is not ideal, though, for any sort of medium wave DXing; don’t consider the KA29 for MW DX.
If the KA29 is better than the DE1129 on the shortwave bands, the improvement is negligible. You’ll be fairly happy with the KA29 while listening to strong shortwave broadcasts. During my review, I listened to the new Global 24 a few hours on 9,395 kHz–an easy catch on the east coast of North America–and the KA29 was fairly stable, producing rich audio.
Here are the cons on shortwave:
Automatic Gain Control
While listening to weak stations, you’ll discover the KA29 to be somewhat sensitive, but again, the AGC circuit is just too active to listen comfortably for very long.
The noise floor is more obvious while listening to weak signals: I believe much of the noise is coming from the internal electronics of the KA29. It produces an audible digital hash sound that makes weak-signal listening a bit of a chore.
Quite often as I tuned around the shortwave bands, I noticed that FM stations bleed through the audio. Check out this audio sample as I attempted to listen to Radio Ryhad:
Indeed, even if the shortwave station has a relatively strong signal (like this recording of Global 24) you can often hear noise:
Fortunately, several of the recording problems I noted with the DE1129 are no longer an issue with the KA29.
The DE1129, when recording radio, had the exceedingly annoying habit of automatically setting the internal speaker’s volume to a high level. While recording, this could not be changed.
Fortunately, this problem has mostly been addressed in the KA29, which does not increase the volume while making a recording, but still fixes the volume at the level set at the recording’s start. I didn’t find this to be much of a problem.
The recording performance is better than that of the DE1129, which produced noisy, muffled recordings. The KA29 will produce fair audio recordings on AM, on FM, and on shortwave. One drawback: you will note a low-volume, high-pitched static noise–a hiss, to be specific–inherent in every radio recording, regardless of band. While it’s not too offensive, nor enough to deter me from making direct radio recordings (at least of strong stations), there is still much room for improvement. Obviously, I can use the headphone jack and an external digital recorder to make better radio recordings. But the convenience of an all-in-one recording device plus radio outweighs the slight hiss in the internal recordings it produces.
All in all? I’m reasonably pleased with the radio recording capabilities of the KA29, and the improvements it’s made over its predecessor. If the Degen engineers could lower the KA29’s noise floor and fix the imaging problems, and add 1 kHz tuning increments, this could be a good value all-in-one radio, a real contender.
Ever radio has its pros and cons. The following is a list I made while reviewing the KA29:
Great audio for a tiny radio
FM reception quite good
MP3 playback audio is good
Onboard radio recording acceptable (see con)
9/10 kHz select-able medium wave steps
Sluggish response to most actions; if (for example) volume control has been used, you must wait nearly 4 seconds before using another function
Awkward menu to navigate
No bandwidth selections
Imaging on SW bands
Fixed 5 kHz steps on shortwave
No adjustable bandwidth
Digital noise on portions of MW and SW bands
Low audio hiss present in all internal radio recordings (see pro)
No back stand
Antenna does not swivel 360 degrees for optimal placement
If you’re looking for a pocket radio to make local radio recordings on-the-go, and the quality of your recordings is not a major concern, you might give the KA29 a try; chances are you’ll be fairly pleased with the affordable KA29.
If you’re a shortwave radio hobbyist or DXer of any stripe, however, don’t waste your time or money on the DE1129. Instead, pitch in $10 more and buy a Tecsun PL-310ET–it has no MP3 recording or playback, but it will receive circles around the KA29.
Thanks to all who participated in our ultra-portable shoot-out! A little over a week ago, I posted recordings of shortwave broadcasts, weak and strong, in an attempt to evaluate which recording–thus which radio–our listeners prefer. I conducted this test on the three radios pictured above: the Tecsun PL-310ET, the CountyComm GP5/DSP (Tecsun PL-360), and the Tecsun PL-380–among the most popular ultra-portables currently on the market. This test was “blind” in the sense that all three radios evaluated were merely labeled “Radio 1,” “Radio 2,” and “Radio 3,” respectively.
To refresh your memory, I’ve embedded the audio samples below for you to hear; but if you haven’t yet heard them, I encourage you to read our previous post before doing so. (If you’re already heard the recordings, simply skip this section.)
Global 24 – 9395 kHz (Strong)
ERT Open/ Voice of Greece (Relatively strong)
Radio Riyadh (Weak)
Rádio Bandeirantes (Very weak)
And now…the results!
The following chart shows how each radio scored out of a total of 106 (wow!) survey responses:
Let’s start with the radio that scored lowest in this contest…
Radio 3: the CountyComm GP5/DSP (a.k.a., the Tecsun PL-360)
Interestingly, the GP5/DSP consistently came in last in every category. I think a few factors outside of receiver performance led to this.
For some reason, the recorded audio of the GP5/DSP sounds out-of-phase. Several of you noted this. The resulting sound almost mimics a “stereo” effect. No matter how many times I made recordings on the GP5/DSP, this feature predominated, and I eventually assumed it to be characteristic of this radio’s DSP.
But I’m wondering now, however, if there might be oxidation on one of the headphone jack conductors, or if the headphone jack on my unit is somehow faulty–? Because of this, before conducting the medium wave shoot-out, I’ll try to clean the conductors with a little Deoxit to see if it makes a difference.
Unlike the PL-310ET and PL-380, the GP5/DSP can’t change AM bandwidths. On the strong recordings, I widened the bandwidths of the PL-310ET and PL-380 to 6 kHz; this improved their audio fidelity. On weak signals, I narrowed the bandwidth to 3 or 4 kHz, keeping both at the same level as I did so. While the GP5/DSP’s fixed bandwidth is well chosen, it simply couldn’t compete with the wider filters of the other two radios on strong signals.
Though the GP5/DSP (Tecsun PL-360) came in last, the irony is that most people who made comments on the survey form actually mentioned that the GP5/DSP was also a strong contender. Here are a few responder’s comments:
“The bassiness of Radio 1 was pleasing to listen to, but the clarity of radio 3 was also pleasing. All three sounded very good.”
“I was divided–Radio 1 seemed to provide the better audio on the stronger stations (not as muddy) yet Radio 3 beat it out on the weak stations and seemed to hold the station steadier (less fading) thereby providing a better audio to hear and understand.”
“I think if I were to place these three radios in order of “listening pleasure” based on the provided samples, my order would be 3, 1, 2.”
“By a small margin Radio 3 seemed to have the best signal to noise ratio and general audio quality across the range of signal strengths.”
Also notable: the GP5 has one very distinct advantage over the other two radios, something that wouldn’t have been noticed in this test: its ETM function, which scans the whole band then automatically stores stations to temporary memory, is almost two times faster that that of the other radios. It also seemed to be equally accurate.
So, who would buy the CountyComm GP5/DSP (Tecsun PL-360)? Someone who likes this radio’s form factor, it’s stable AGC, and quick ETM scanning. Keep in mind, we are comparing this model with two of the best radios under $60, in my opinion. Had we compared the GP5 with most other sub-$60 radios, it might have won that shoot-out, and with ease.
The Tecsun PL-380 came in a very consistent second place in this shoot-out.
The ‘380 is one of my favorite portables on the market; for many years, it has been my go-to radio for one-bag travel.
Before recording the shoot-out, I guessed that the PL-380 might take first place. But up to this point, I had never actually compared it with either of the two other radios in this shoot-out. Listening to the blind samples, I tend agree with the results. Still, the PL-380 is a great value and a fun little radio, one I can still easily recommend for travel.
As you can see from the graph, the Tecsun PL-310ET won our shoot-out in every category–and by a fairly wide margin:
While comparatively few participants’ comments were specific to the PL-310ET (“Radio 1”), it’s interesting that these most often made note of this radio’s very close resemblance to the PL-380 (“Radio 2”).
The PL-310ET had only a slight advantage over the PL-380 to my ear, but it was enough; so along with most survey respondents, I took note of that advantage.
Now, I know this much: when people ask me whether they should purchase the PL-380 or PL-310ET, I think I’ll suggest the PL-310ET. In the end, it makes for a better travel radio because it also has an external antenna jack, one of the few sub-$60 radios that has this useful feature.
When I find the time in the next month or so, I plan to test the same radios in a medium wave (AM) shoot-out. Weak-signal medium wave will put AGC circuits and internal ferrite antennas center stage. Please be patient, however, as these tests actually take time to put together and evaluate. Again, your participation will be most welcome!
I picked one up today, and overall, I’m impressed. It does have complete coverage from 2.5 to 26.1 MHz as advertised, and overall, it has very good sensitivity and adjacent channel rejection for a small portable (in fact, the best I’ve heard from such). Sure sounds like some sort of DSP filter is involved. Reception is at least as good as my old Grundig Mini 300 and much, much better than a Degen DE22. Clipping an external long-wire antenna did not cause overloading (I was very surprised by this). AM BCB reception is actually quite decent: I was able to listen to several distant stations that were only 10 kHz from local ones. Audio is OK but not great, and the case does not stand up stably. I guess you can’t expect too much from a $30 radio. No case or earbuds are included.
By the way, if you go to a local Radio Shack store, be sure you get the internet price. We have two stores near my house; both had the radio marked as $39.99 instead of the $27.99 online sale price. The guys at the first store said “sorry, we can’t change the sticker price.” No sale. So, I went to the other store. When I pointed out the web price to the young women helping me there, she said, “this isn’t right” and called her manager over who overrode the store price with the cheaper one.
So, who makes this radio? Good question. The back of the case says “Custom manufactured in China for Radio Shack Corporation.” Maybe Tecsun?
Sounds like this may be a great portable for the glove compartment of a car, or to keep in your backpack/briefcase.
Thanks, Mike, and please share any other comments about this radio as you use it.
Very good question! Though I haven’t been inside a RadioShack in a couple of months, I’ve never noticed this portable on their shelves. In fact, I don’t even recognize the form factor as a re-badged Tecsun or Degen.
Your goal was to assemble the best shortwave listening set-up possible for your virtual budget of $200 US. You were tasked to track down a radio kit that would keep you in touch with the world, and potentially afford you some very unique DX. [If you haven’t read the full virtual radio challenge, including all of the limitations you might face, I encourage you to check out this post before continuing.]
Your Reader Responses
And, wow, what great responses–! First, I want to thank all who participated in this challenge. No two responses were identical. Some truly surprised me…I must say, I sincerely hope you enjoyed this exercise as much as I enjoyed reading what you’ve sent to the SWLing Post!
Below you will find ten responses from readers, representing remarkable diversity in radio set-ups. Note that my comments follow; they are italicized and in bold.
Now, with no further ado…I welcome you to radio DX on Tristan de Cunha!
from Frank Holden
First up, Frank Holden, who submitted his entry at 3:00 AM–prior to leaving on a 6:40 AM flight. Obviously, travel was on this Post reader’s mind.
Based on both my own experience and recent swling.com research I would choose a:
Duct tape (for securing joints on Squidpole and taping top of ant to top of Squidpole) $2
20 metres of wire for antenna with fitted plug. $10
Cable ties for securing Squidpole to stake. $1
Coil 3mm diam polyester line for stays $10
One dozen big tent pegs. $12
Big hammer [Available locally!]
Squidpole Antenna (Photo courtesy of http://www.perite.com/)
Total is $210 Australian, so you will get change out of $200 US.
Feed antenna up inside the Squidpole and tape at the top…. The rubber ‘bobble’ is removeable.
Maybe run a short length of coax from radio to base of Squidpole.
Make sure the Squidpole is well stayed. My experience in VP8land and Tierra del Fuego is that the constant flexing in high winds will lead to squid pole failure. Mine were secured to the taffrail on my boat… i.e. at the base and 50cm up from base…. Failed at the 50 cm point. I have also had a 5 metre high quality (marine grade) alloy whip fail in the same manner.
Utilise rest of baggage allowance with warm clothes, rum (power outages… for use during), etc.
Thanks, Frank! I love the idea of the Squidpole as it can give you a little height when trees are absent. I have used a similar telescoping pole for Ham Radio QRP operations: a Jackite pole. I’ve broken the tip section twice already due to my own clumsiness–fortunately, the tip can be purchased separately. As you suggest, I bet the winds on Tristan Da Cunha would give the Squidpole a run for its money!
The Ham It Up v1.2 – NooElec RF Upconverter converts your RTL-SDR dongle into an HF receiver.
I propose using my current setup, since a laptop is a freebie here. I use the following in my setup:
That’s $157. That leaves $43 for a 25? length of coax and two MCX adapters. Coax run is $15 (at $0.39/ft for RG-8X.) I forgot how much the adapters were, but less than the $28 left over after buying the coax run.
Downside? I have no pole to support this, and houses on the island are only one story structures. I’ll have to attach the high end of the sloper to the peak of the home where I’m staying, and I’m sure that height is less than the 25? recommended by AlphaDelta. In addition, I’ll have to plant a stake at the lower end of the sloper to keep that end the recommended 8? above ground. I also made no provision for extra power if a power outage exceeded the amount of juice in my laptop battery.
If push came to shove, I would drop the MFJ 1020B for an extra $50 to buy supports or an extra battery.
Thanks, AB3RU! I’m willing to bet that you might find something on the island to support one end of your sloping antenna. It might be a challenge to meet the 25′ recommended height, as you stated. Still, this is an innovative and quite portable option!
Here are my choices:
A 50-100m wire to be used as an antenna for SW and MW. I imagine I’ll be able to catch a few MW stations from South America or Africa. As for choosing a radio…
I’ll need a good radio which allows using an external antenna not only for SW (all of them do) but also for MW (few of them do). I think there is only one radio which fits this requirement within the budget: the Sony ICF-SW7600GR, available on Amazon.com at prices around $140. My other choice would be a Sangean ATS-909X which works very well with external antennas, but it’s more expensive.
I’ll also need two packs of 4 AA rechargeable batteries and a charger.
Thanks, Tudor! I believe your choice of the Sony ICF-SW7600GR is a very good one, as the Sony is a solid performer. It would be a challenge to find a new Sangean ATS-909X within your $200 budget–you would need to track down a used one, most likely. With the PL-660 in tow, you would then have a full $60 to purchase batteries, charger, and your antenna wire. Very workable!
It is through hole soldered so replacing parts is easy. Bring a bag of spare parts and a couple batteries. Get two headphones so that you and a friend can listen at the same time.
Thanks, KK6AYC! At $110 US, you would certainly have enough budget for spare parts, batteries, and antenna wire. While a regen receiver may not be for everyone, these do provide excellent sensitivity once you pass this rig’s learning curve for tuning. If the winds blow your external antenna around, you might have to ride that regen control! Great alternative to the typical portable–!
from John Treager
Next, John Treager, who writes:
Neat thought experiment! I’ve recently got back into SW listening after years away. I’ve been hitting your sites for two or three months and your weak station comparison really grabbed my attention but this one has lit the fire again.
[…]I’m a contract engineer who lives away from my primary residence most of the time so this challenge kind of strikes a chord. And, as I’m getting back into SWL, you’ve given me a reason to research (something engineers love to do!).
If I’m renting a room with a family on the island, headphones are a must. I’m cheap and traveling light so let’s go with Sony MDRZX100 headphones. I’ve used them for quite a while and like them. I find them comfortable for at least a couple of hours. Currently $15.09 on Amazon.
I enjoy the challenge of simplicity so, as far as an antenna goes, I would choose a simple long wire. Either a reel or one I build, $10-15. I get as much enjoyment from fussing with antennas as I do from turning knobs and dials. If my simple wire antenna doesn’t work when I get on location, then investigating and tinkering with antenna design and construction will fill the hours!
By the rules of the challenge, power is available but somewhat unreliable it sounds like. To meet that, I’m going with rechargeable batteries and enough to last for a while. AmazonBasics AA NiMH Rechargeable batteries (16 pack, 2000 mAh). Not the newest version, but should suffice for one year and 16 batteries should be enough for extended periods of no power. And, this may be a bit of a cheat, but I use AA batteries for everything, so I already have a charger!
Next, some sort of reference. I usually use either my laptop or a phone/tablet for frequencies/times from various sources, but given that there is no internet access in the residence and power may be occasionally spotty, let’s go with the World Radio/TV Handbook as a backup (I do miss Passport to World Band Radio!). I found WRTH on eBay (new, 2014 edition) for $27.24.
I assume I will have notebooks and pens for other reasons, so not included in the total.
Thanks, John! That should be enough AA batteries to keep you going well over a week with no power. Packing a WRTH makes a lot of sense. Via the island’s library Internet–however variable–you could download WRTH updates, as well.
from London Shortwave
The Global AT-2000 (Photo: RadioPics.com)
London Shortwave sent his suggestion in by tweet–a simple, proven combo:
If a laptop was coming along, I would have to use an SDR.
I would get the Afedri SDR USB-only model [see AFEDRI SDR-USB-HS above] for $159 (board only, I’d have to mount it in a sardine can). I would then use the remaining $41 for a cheap used antenna tuner and a random wire for an antenna. I think this kit would make for an excellent listening post.
Backup power would be a concern with the outages, so I am contemplating a 6-volt battery backup power system to power my Phillips 4-port USB hub (6 volt DC in requirement). From there the USB-hub will power/charge a Dell Venue 8 Pro tablet (the laptop), the Afedri SDR and maybe a USB-powered speaker? Would have to test out this backup power scheme before boarding the boat!
I think I could do all of the above for $250 including the backup power system. Although it would likely push $300 when wires, cables etc are all in (does not include the tablet/laptop).
Thanks, Princehifi! So you’re a little over the $200 budget with all of the accessories, but if you already have a laptop and tablet, I think you could tweak your set-up to meet the budget goal. I did not realize that there was a USB only version of the Afedri SDR–I might have to get one of those myself!
Here’s my list. Where can’t get it locally and I don’t have a firm shipping cost, I’ve estimated it as an additional 20%. Stuff I can get locally (Radio Shack, etc.) I haven’t added any shipping or sales tax.
(That’s right, a spare radio. Because middle of nowhere.)
Grand total: $192
Now if I’m allowed to scrounge in the parts bin for stuff like 22 gauge antenna wire, RG58, and earbuds, there might be enough left over for a SECOND spare radio and 4 more Eneloops!
Thanks, Rob–you have a plan, indeed! Well thought through! I, too, would be very curious what sort of medium wave DX I could hear in the South Atlantic, especially since you know there would be no local blow-torch stations around. I have the Grundig version of the Tecsun AN200 and find it an essential antenna for portable MW DXing.
Grand total: $156.89 (all qualify for free shipping)
I’d guess I would save the rest for repair costs in case the radio acts up. Of course, I’d take the one I already have as a spare. When in remote locations, backups are essential so I probably bought more than most people think I need. And as far as the battery charger, rapid chargers are bad for most NiMH batteries so I went with a slower charger. And don’t forget that the Tecsun can charge the batteries in the radio when not in use.
Thanks, Michael! You are erring on the side of having extra batteries and more than enough wire for antennas; there’s no way you’ll run out in your one-year stay. On Tristan, I know that locals often trade supplies: those extra batteries may turn into an antenna support!

I love your site, I’m there everyday and almost forgot to enter so here it is:
1. Kaito 1102, I have had good luck with it and it has ssb, second choice would be a Tecsun PL-380, I really love this radio and it’s a great little dxing machine but no ssb. The Kaito is 64.95 on Amazon, free shipping.
8. Radio Shack 1/8th inch miniplug for end of coax, $4.00
Wow! Thanks, Kenny B! Other than the KA1102, your complete kit is DIY–I like it! You could build the battery charger and antenna prior to leaving.
1. Receiver: Wandel & Goltermann FE-8 Spy Radio Receiver (US$ 120 at a Hamfest)
Wandel & Goltermann FE-8 Spy Radio Receiver from the cold war (mine was manufactured in 1963. I bought it at a Hamfest in Sweden a month ago for the equivalent of US$ 120.[…]
For ruggedness there is nothing else like it. It is completely sealed and constructed from a single piece of die-cast machined aluminium and stainless steel. Just the thing for wet and rainy Atlantic islands! Covers 2.5 – 24 MHz and only needs 6 Volts at 8mA. A pack of twelve AAs will fit in my pocket and last at least a year with about three hours of listening every day. No adapter, no charger. The razor sharp 3.1 kHz Collins Mechanical Filter is not ideal for music but hard to beat for general news and SSB utility listening. Like the famous Collins R390 it uses a mechanical “digital” dial accurate to 1 kHz which also glows in the dark. […]It is smaller that a Tecsun 660 though it weighs a lot more. More about this radio here http://www.cryptomuseum.com/spy/sp15/fe8.htm
2. Antenna & Earth (US$ 15 in any electrical store)
Random length PVC insulated wires with a banana plugs- total 50 meters. The radio has a hi-impedance input and is sensitive enough to do a great job with just 20 m of wire. The rest is spare.
I’m all set for the trip now with $10 to spend on a supply of chewing gum. I know that this radio setup can easily deal with whatever is thrown at it… the question is if I can!
Thanks, Anil! Wow…I never saw that spy radio coming! It does look like an ideal radio for prolonged use and for pretty much any environmental conditions. I hope you realize that I will be bugging you (okay, pun intended!) to provide us with a few broadcast recordings from the FE-8. It’s certainly got my interest piqued!
Now, that was fun! Thank you all…
I know this sort of challenge may not appeal to everyone, but I really enjoy it. This sort of exercise forces you (though safely) outside the comfort-zone of a home radio set-up. Your responses are truly innovative. I only wish the Post could actually send our participants to Tristan de Cunha to try their set-ups out first-hand! I, for one, would love to come along…
Thanks, again, for your participation! If your response wasn’t included above, or I didn’t respond to you directly, please let me know: it’s possible I skipped over yours by mistake as there were quite a few responses to collate, and my email is managed by a rather discriminating SPAM filter.
Meanwhile, if you think of an alternative set-up–or would like to add your own to this post–please comment below!
