Question about Sangean ATS 909 AM/FM/SW Radio

1 Answer

External antenna on connecting the supplied external antenna i find a reduction in overall performance ie reduced signal strength, the signal on sw is now stronger on the whip which is the reverse of how my 909 usually behaves i use the external alot which is out along the guttering of my home,yes exposed to the elements......however i have noticed lately thatĀ  a slight movement of the connector to the radio, from the external, the signal intermittently dropped? has my external died? or is it the am ant in socket on the radio, would appreciate some help i know i can pick up an external here in uk for around 20.00 pounds,but would that be twenty wasted if it turns out to be the 909 itself?? happy swl steve

Re: external antenna

You can get good assistance at the DX 398 Group at Yahoo! The DX 398 is the same radio as the ATS-909. It was the name used by Radio Shack when they marketed it. Here's the URL for the DX398 group: They will definately welcome your questions and will likely provide some valuable answers.

Nothing but static on all bands

There may be interferences from electrical appliances fridges, TV. Move the radio to some other place. For AM rotate the radio to get the best signal. For FM and SW deploy the telescopic antenna. For SW you may use an external antenna. For SW, to tune in on a station you need to know the broadcast time and the frequency.

Grundig Satellit 800 external antenna configurations

It looks like you have a real scientific project. It sounds fascinating and it seems to go well beyond the mere enjoyment of a simple Short Wave Radio. My suggestion: Put your hypotheses/questions to the test and you will form an informed opinion.

Eton e5 sw shot

The SW FET preamp transistor, Q1, on the underside of the circuit board blows if a static electric discharge hits the whip antenna. In my case, a cat rubbing against me & the radio on a very dry winter day did it in. The back & circuit board has to be removed to get at it. The micro transistor & the solder connection are very tiny, so hard to replace. The antenna jack should still work, because the preamp is only for the whip antenna's SW reception. An easier solution would be to just run a wire from the antenna jack to the whip antenna, but you would no longer have the whip's preamp benefits, or just use a longwire antenna connected to the jack for SW. Also beware plugging into the jack disables the AM ferrite antenna inside, so you might not want anything plugged into it for AM reception because the internal ferrite seems to perform better than any external antenna.

Wont stop on a station when search button is pressed

The autosearch feature stops on stations based on a preset threshold for radio station signal strength.

If your radio has done this on both AM and FM from when it was new, it is probably an internal problem with the circuit board electronics or possibly because you are in an area where strong signals are absent (such as a rural area or inside a building that interferes with signals).

If the radio won't stop searching at all, the 'Search' button' may be stuck.

If you find that your radio is skipping stations only on FM, it may be a defective or broken external antenna or, again, maybe you are in an area where strong signals are absent (such as a rural area or inside a building that interferes with signals).

Hope this helped.

Static on every station, no matter where i plug it or how i rotate the antennae. this just started in the last few months

Possible that you have a EMI interferance in your circuit or power which carries into the set..Use the set in the battery mode and swtich off all the mains in your house. if this solves, then check on by one the connected appliances which might produce this static. You could also take the set to another location to see if this reduces off . in this case you will have to check if there is a lurking interferance from the power source. I suppose you might not get this faultt with the FM but MW and SW is bound to pick up the static unless the signal is powerful. Please also try to check your external cords, if possible change the location of the antennae. Further any fault on the radio IFT/filters could be considered. Hope my advice helps you . Good day

External entenna not working, what can i do?

By "external antenna not working" I can only assume that you can't receive any SW or FM signals. Does AM work OK? If so it's likely that your receiver still works but the AM uses a different and internal antenna.

If it's still under warranty then return it to your point of purchase and ask for another one. If it's out of warranty (which I suspect) there is probably not an economical repair. If your external antenna is broken in some way the only place you can get a replacement for it would be Sangean. Typically those manufacturers only provide parts during the warranty period. That is illegal in many states. Most states require manufacturers are required to stock replacement parts for five years after last production. This is one of the brands that tries to hide from the consumers if there is a problem. This is unfortunately the case for many overseas products. If it came from China then it's shipped with no warranty. The seller has to take the hits for defective products.

I purchase a Grundig S 350 and purchased the sangean Antenna-60, I don't know where the antenna attaches???

The Sangean ANT-60 comes with an adapter that lets you clamp onto the existing antenna on your S350. Using this adapter and the clip provided will be a good enough connection. The S350 does not come with an external antenna connection port for a 1/8" mini plug antenna so this necessitates the use of that adapter and clip.

Excessive static on AM stations. Waves in and out. Not so on car radio. Is there an antenna to eliminate this?

Turn on the radio and turn the AM/SW BAND switch to the AM position. MW appears in the display. Use the outer ‘fast’ tuning knob to find stations, fine tuning with the inner ‘slow’ knob
when needed.

• If there is interference from adjacent stations, place the BAND WIDTH control in the NARROW position. If there is no interference, leave it in the WIDE position.

• If there is excess background noise, turn on
the SW LPF switch, which may minimize the noise.

• If a station is so strong that audio distortion occurs, reduce the gain level with the AM/SW RF GAIN control knob by turning it counterclockwise.

• The telescopic antenna does not have to be extended for AM reception. The radio has an internal, directional, ferrite-bar antenna for AM reception.

• To optimize AM reception, swivel the radio until maximum signal strength is achieved.

All of that being said: It's very tough nowadays to receive AM in this 2008 electronic world. If your able install a longwire SW antenna outside, and have access to a good earth ground, you can boost the AM signals and beat the noise being generated all around you.
