Question about Sony ICF-SW7600 AM/FM/SW Radio

3 Answers

Problem with FM reception.

My radio is the 1991 edition.
FM ceased to work. Only part of the band at first - then nothing except the interstation hiss over total Freq range. Some motorboating in the early atages of failure then nothing.

No problems with AM, SSB & SW

Sony radios of this era had notorious capacitor problems.... also several other brands were affected. These capacitors were underrated and the technology to make them was not at it's best back then. The cure is to replace the capacitors on the board with new electrolytics. About 28 of them need to be replaced but the big problem is to find someone to do this. the original capacitors are surface mount and must be removed and new radial lead caps put in their place, some are rather tough to get at and the new ones have to be placed carefully. My SONY ICF-SW7600 now works as new and maybe even better!
I have done this myself as I have skills working with surface mount capacitors. I offer my services to those who cannot find service for their radios. Please email me for details, I am not into making bucks on this, I just want to see these radios kept working and bringing enjoyment to their owners.

I just purchased the G6 Aviator. The FM band works well, but none of the AM or shortwave stations get reception. I have tried the antenna up and down, indoors and outdoors with no success.


It sounds like the whole am band is not working which includes the shortwave bands, there is no remedy to correct this and is clearly a manufacture defect. The best solution is return the radio because there is nothing more that can be done in it's present condition.

Loud buzzing and getting only AM reception on the FM setting. Any ideas?


Possible that the band knob has slipped on it's shaft or has become out of line or loose. Try pulling the knob off, making not of the position and see if the shaft is loose. Try to get back to me on this.....

Grundig Satellit 800 powers on but no sound on any bands or modes. It appears to have a signal on AM but nothing on FM. It's completely dead and the MAIN large tuning dail will not function either. All...


HI,
THE FIRST THING YOU HAVE TO LOOK FOR IS WHAT KIND OF ADAPTER 9V 1AMP YOU SHOULD
HAVE FOR THAT PARTICULAR RADIO AND ANTENNA FOR SW AND FM SHOULD BE CONNECTED.IT MUST BE THE ADAPTER THAT'S ON THE OUTS NOT ENOUGH VOTAGE TO POWER THE RADIO.

AM radio reception


You are correct William, reception is not what it used to be for many reasons. Some corporate owners and local owners have spent much more maintaining FM facilities, and many have neglected the AM's. A good part of the AM signal is via the ground radials beneath each AM tower. In time these radials deteriorate, and with it the signal. Years ago stations licensed as daytime only shut down at night. Quite a few are now allowed to stay on with greatly reduced power, adding to the noise floor at night. You also have more AM licensees now than in the 60's. Unfortunately many of the really knowledgeable AM RF engineers have retired, or are close to doing so. AM directionals require a very experienced engineer. In addition we have many Part 15 radiators, that are devices that radiate a low level RF signal. Every home is full of them, thus more interference. We have power distribution systems that generate huge amounts of noise across the band too. Then there is the issue of manufacturers who have spent more on the FM receiver side of a radio as more migrated to FM. In the 60's, very few were FM listeners. Gone is sensitivity, selectivity and frequency response in the newer AM radios. There are a few exceptions, the CC Crane, and RCA SuperRadio, both sound good with great performance. By the way, the RCA WAS the GE SuperRadio. I also like to pick up some of the vintage radios on EBay and other sites, plus occasionally at yard sales. Unless you are in the country and don't have a house full of gadgets, DX listening can be difficult, but not impossible. Best of luck, capttomconroy@jetbroadband.com

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.

Don't take your radio to work. Get your work done , then go home and listen to it. You will get better reception in a res. area.
