Seeking electronics advice (battery-operated Sangean radio)
Self | 1/2/'11 | Zionist Conspirator

Posted on 01/02/2011 11:03:21 AM PST by Zionist Conspirator

Well, it's not enough that I have to put up with ongoing computer problems, now my radio is messed up.

Several years ago I purchased a Sangean portable battery-operated radio from The Short Wave Store. It's one of those radios where the batteries are the primary power source (the AC adapter had to be purchased separately and is very large, heavy, and unwieldy). Unfortunately, for whatever reason, batteries no longer work in it.

Now let's be absolutely clear about this: it's not the batteries themselves. Not only are they only three months old (and they're Energizer lithiums at that), but I purchased some brand-new batteries out of the store just day before yesterday. The radio simply cannot tell it has batteries in it at all. No batteries will work in it and without batteries its portability is dead. And the large heavy adapter makes moving it around and powering it with electricity very inconvenient.

Okay. So it's not the batteries. Plus I've gone into it with a pencil eraser to clean off any corrosion or whatever. Still doesn't work. And I've pushed the re-set button, in the off-chance that that might solve the problem. I didn't expect it to, and it didn't.

Does anyone out there have any insights into this problem or any suggestions as to what can be done for it? Is this problem fixable? With my ongoing computer problems I really don't need to spend over a hundred dollars on another radio because the one I have can't tell it has batteries in it.

Help please?

My guess is that there is some connection that has worked loose in the body of the radio; and I doubt that you can crack the case open. If this was my radio, I’d contact the SW store, or, if you have the literature that came with it, there may be a factory service center listed.

Radio Moscow and Pravda are better than anything on ALL of TV including Fox with Megan Kelly bashing birthers and Rove pimping for Obama 2012. I dumped Obama TV after he was elected. I heard about Prince Al Waleed’s Fox more and mor epimping for Obama based on posts here.

The socket for the AC adapter usually incorporates a set of contacts to switch the radio from battery to AC. Sometimes they corrode. Try plugging the AC adapter plug in and out and wiggling it a little to see if it will start working off the batteries. Do it with the radio on, the ac adaapter NOT plugged in and the batteries in, so you can hear if it starts to work.

If you cannot get the Sangean fixed and need to buy another shortwave set, I highly recommend going with Grundig. I bought a Grundig Satellit 700 back in 1994 and it has had nearly daily use since then and still works like the day I bought it. The only issue is that some of the numbers have worn off the buttons!

I don't use it for SW that much anymore as the web has become my primary source of information, but it wakes me up every morning at 5AM to my favorite classical station. When I am in the mood for some DXing however (especially on a warm summer night in my backyard), I can pick up just about anything that's available.

But there is far more to radio than Radio Moscow.

We just listened to a round table of amateur radio operators on 40 meters, from all over the U.S. One was a pilot, one a farmer, a cop and several were retired...The topic was the U.S. state of affairs and level of government corruption and recent weather activity in their separate regions.

It was very interesting, and they were not connected by wires or the Internet.

The web-site you linked says:

Requires four “AA” batteries (not included.)

There are no lithium “AA’s.” Does it have a lithium memory backup battery? Anyway, if you have a voltmeter, check the AA batteries. If they are rechargeable, your charger may not be working.

The earlier tips about corrosion in the AC adapter connector are right on.

The Shortwave Store is just a web site that sells short wave radios, and I purchased this one several years ago. Whatever warranty that might have come with it is long gone.

The only thing that came with it is a little booklet in English, French, Dutch, and German that tells how to operate it. So far as I know there aren't any service centers.

Thanks anyway. I appreciate it that fellow FReepers are willing to help me.

But FR is way more interesting. :)

I have pretty much the same radio, a Radio Shack DX-398. Purchased it about 9 or 10 years ago, but I use it with a small 6V-300mA wall wart since it plain eats batteries. Maybe ½ hour if I'm lucky. I run the line out into a good amplifier. Except for the battery situation, I love this radio. Sounds like you have an open circuit somewhere between the battery compartment and the power switch. Never had mine apart, so I can't say what it looks like, but it's probably a one-minute soldering iron fix.

In fact, there’s no “Radio Moscow” anymore. Subsequent to the disolution of the CCCP in 1991, the name was changed to “The Voice of Russia.”

At first, the newly-christened station transitioned away from the old Soviet-style propaganda, and they even carried some interesting programs.

But ever since Putin and his KGB buddies took over the Kremlin, the VOR has steadly been moving backwards, until nowadays it’s almost as anti-American — and as boring — as Radio Moscow was in the “good ole days.”

They say "Engergizer Advanced Lithium." I don't know what that means, but they're supposed to be good batteries.

Anyway, if you have a voltmeter, check the AA batteries. If they are rechargeable, your charger may not be working.

That's not the problem. I bought new batteries just day before yesterday and they don't work in it either, but they do work in my remote control (I checked them). So it's not the batteries at all.

I'll try to check that out. Thank you.

Are you sure the lock switch isn't set accidentally?

Also, you might try pressing the reset button on the bottom of the unit. That may clear some electronic snafu within the unit.

Me too, except for that blasted “beep” when you change bands or punch in a frequency. I know there’s a way to disable the beep — found the instructions on the Internet thanks to Google. But I just haven’t yet worked up the courage to take the thing apart!

I think you’re operating here under some kinda misconception. I have the same radio. A very small power adapter is all you need. Take the Sangean to your nearest Radio Shack store. They’ll be able to fit you out with the correct 6V adapter and matching plug.

I have a similar radio (Grundig Yachtboy 400PE), but not this one. I found the manual on the internet.

The lock switch is in the middle of the right side of the unit, according to the manual.

There is no more Grundig.

It was bought out a number of years ago by the Chinese.

They now operate under the Eton label.

Used Grundigs are available on Ebay and elsewhere but get big bucks.

I don't have the beep. The radio does turn itself off and then start to alarm with a beep (ascending volume) between 11:15 and 11:45 am, and I don't know how to cancel this 'feature'. Drives my wife nuts.

Sangean switches out battery circuit when adapter is plugged in. The Sangean adapter center pin is negative, outside contact is 6 volts.

I don't know how they switch out the battery supply, could be electromechanical (relay) or solid state (electonically).

At any rate if adapter is not plugged in radio should default to battery circuit. Since it isn't you will have to open up the radio and follow the positive lead of the battery compartment to circuit board and see what you can find. A meter would help but you may see something visually.

My camera says, “Dittoes!”

The performance of the lithium AA’s in my camera has been outstanding, by the way. Held out just as advertised — ca. eight times the useful lives of akalines.

On the other hand, when I put them in an MP-3 player, they didn’t last much longer than those ultra-cheap Costco akalines. Happened this way twice. So I’d recommend against putting lithiums in a radio. Probably would be a huge waste of money.

I’ll up the Grundig recommendation and add you should find a pre-1997 model that uses analog dials....

My two oldest Grundigs, one from the 1980’s and the other a 1995 or so, have lived longer than the newer 2 2000’s model years that I bought, both had the electronic dials die from what looks (post mortem autopsy) like corrosion that ate the contacts on the silicon.

The new Grundigs are incredibly light weight though... however I don’t trust them for long term use...

Hmm. Maybe they got so many complaints about it that models newer than mine didn’t incorporate the beep.

(Mine is vintage ca. 1999.)

Try Googling both “DX-398” and “Sangean 398.” You might find something on point.

from Wikipedia: Grundig AG is a German manufacturer of consumer electronics for home entertainment which transferred to Turkish control in the period 2004-2007. Established in 1945 in Nuremberg, Germany by Max Grundig the company changed hands several times before becoming part of the Turkish Koç Holding group. In 2007, after buying control of the Grundig brand, Koc renamed its Beko Elektronik white goods and consumer electronics division Grundig Elektronik A.Ş.,[1] which has decided to merge with Arçelik A.Ş. as declared on February 27, 2009.[2] ----------- At the end of June 2000 the company relocated its headquarters in Fürth and Nuremberg. Grundig lost €1.281 million the following year. In autumn 2002, Grundig's banks did not extend the company's lines of credit, leaving the company with an April 2003 deadline to announce insolvency. Grundig AG declared bankruptcy in 2003, selling its satellite equipment division to Thomson. In 2004 Britain's Alba plc and the Turkish Koc's Beko jointly took over Grundig Home InterMedia System, Grundig's consumer electronics division. In 2007 Alba sold its half of the business to Beko for US$50.3 million,[5] although it retained the licence to use the Grundig brand in the UK until 2010, and in Australasia until 2012.[6] Grundig S-350 Multi-band Receiver In the United States, products marketed under the Grundig brand are manufactured by the Eton Corporation (formerly Lextronix), based in Palo Alto, California. Spain's Grupo Vitelcom is licensed to manufacture mobile telephones using the Grundig Mobile brand, and auto parts company Delphi manufactures car radios branded Grundig. In 2007 Grundig Mobile announced the U900 Linux-based cell phone.[7] ----------- Go find a pre-1999 model... they will last forever.

The switching is mechanical and is internal to the power connector. The power connector is soldered directly to the circuit board. The battery connectors are also wired directly to the circuit board.

If the radio works with the external supply, then the problem is almost surely with the power connector.

Get some contact cleaner, and squirt some into the connector, then work the power connector in and out a few times.

If this doesn’t help, you will have to live with it as replacing the connector is a difficult and tedious process that would cost almost as much as a new radio if you paid a tech to do it.

Taking one of these radios apart is a tricky proposition, and not for a newbie to attempt.

I agree with the analog dials as it allows for much more precise tuning - in SSB mode, the Grundig 700 will tune in 100hz increments (which is pretty darn precise in a 1.6 to 30Mhz range).

The Grundig 700 is a brick. While newer models are much lighter, when it comes to electronics, I usually get better long-term performance with devices that have some heft.

Dittos on the analog dial recommendation.

Digital is fine if you know exactly what frequency you’re looking for, but if you’re just searching, analog is the way to go.

I have a high end Satellit 3400 which is a beast, and a Panasonic RF-2200, which, in terms of performance, simply blows it away. Both are from the eighties.

In one respect, the 3400 is ideal in that it has analog tuning and a digital counter for a frequency readout.

I'm not familiar with a "lock switch."

According to the manual, http://www.sangean.com/products/download/manual/ATS-505_IBOK.pdf , it's right above the volume knob. That's shown on page 2 and designated a "LICK switch" on the next page 2. Seems to be just two page 2s and licking is surely optional.

Well . . . I did what you suggested. It didn't work.

There must be some kind of damage on the inside that prevents it from using its batteries. I have a friend who's an electronics repairman. Maybe he can fix it. If not . . . I'll just have to "live with it" (as a fellow FReeper put it). But what a pain in the tail!

Yes. As you push the external power connector in, it pushes a spring aside which moves an internal contact from the battery position to the external power position. The spring also has the function of holding the external connector firmly in the hole.

You bet. We have 3 put away, one all band crank radio, one DC/AC, and one which uses AC. Not to mention my ICOM which can hear and talk world wide on DC.

If s*** ever really hits the fan, they'll likely be the only things that actually work.

This is so embarrassing.

I'd like to announce that my radio is fixed, but technically, I can't . . . because it turns out it was never broken in the first place.

Turns out I wasn't properly placing the little ribbon (it's there to help lift out the batteries, but I didn't know that) and it was covering one of the anodes. My schoolmate/repairman showed me how to place the ribbon when putting in batteries and it works like a top.

My face is red, but I'm so relieved!

As more than one poster noted, I was wrong to say there are no lithium AA batteries. There are now a dozen or so lithium battery chemistries which yield varying voltages, including 1.5 v AA’s. Sorry for the error.
