Sony STR-DE475 – Fm Stereo/fm-am Receiver Manuals

Dipoles work OK when the signal is adequate, but when multipath is stronger than the direct signal AND the tuner has inadequate alternate channel selectivity, it’s time to forget about clear reception and that’s what I have here- as I wrote, I’m very close to an antenna farm and that’s not good for someone who likes to listen to a college station that’s weaker than all of the others. Here’s a photo of the kind I’m referring to. It’s possible that some are two wires, but many aren’t and I have seen several that had been cut. There are lots of good vintage FM tuners on eBay. However I do note your Public radio service is very limited compared to what we enjoy. That pretty much has you covered. Getting back to the original post it seems impossible to help the OP. I have been on some FM forums and this question is asked. There seems no easy solution.

Share on Facebook If your cable TV provider supplies FM radio stations, you can pick up the signal through a cable connected to your home theater or stereo receiver. Some receivers are equipped with a coaxial input to connect with a cable. Other models have a pair of spring-clip connectors that hold the two wires for an FM antenna. For a wire connection, you’ll need a device called a Balun transformer, which has two wire leads on one end and a coaxial jack on the other.

A Balun transformer can also be used to connect a wire-lead receiver to a coaxial cable antenna for improved reception. Coaxial cable with threaded coupler on the end for the receiver connection.

The frequencies used for FM radio transmission are very close to those used for VHF television signals, and an ordinary TV antenna will work beautifully with your FM radio or your stereo tuner.

Jim and Bob’s DIY Mods For those interested in modifying tuner audio sections, this page offers a few general suggestions, followed by specific information relating to many Kenwoods and several other vintage tuners. Return ground path – On the Kenwood KT , there is a way to help ensure the integrity of the return ground path.

There are four screws that clamp the circuit board to the steel frame, which holds the power transformer and more. Loose screws can cause electrical problems in the KT and other tuners. First, remove the screws and inspect the board and frame for corrosion or dirt. Second, clean the interface with Caig DeoxIT or another commercial electrical contact cleaner. When reinstalling the screws, don’t re-tighten them so much as to crack the circuit board – just good and firm.

Power supply – Raise the transformer off the chassis with rubber grommets. Measure AC on chassis to outlet gnd with plug oriented both ways, mark plug for lowest noise.

Auxiliary and RCA Inputs

The circuit is rather simple, uses only one transistor and few passive components and performs well in terms of frequency stability, almost zero drifting after about 4 hours of continuous operation. With 12 volt DC it will deliver 1 watt RF power. The most important parts of the oscillator are the transistor Q1 and the tuned circuit, which comprises the inductor Ll and the variable capacitor CV1.

When the battery is first connected, a brief surge of current flows from the collector to the emitter of Q1, causing an oscillating i. An oscillating voltage therefore appears at the junction of Ll and CV1.

They are quite rare and very hard to find in such pristine condition. It still has the original patina, dark brown and copper just like the factory produced them. So many of these radios have had the patina polished away, missing the reins or the saddle. Blake has replaced all of the paper capacitors, tested and replaced bad resistors and checked all of the tubes. He performed a proper alignment, making this little five-tube, AM only radio play like new.

A very cool gift for that horse lover, or man cave.

An FM (frequency modulation) antenna connected to a stereo system can help a receiver pull in better signals from FM radio stations. Stereo receivers typically have a pair of FM antenna .

TV antennas have compromises built in.. All of this it tied together and the efficiency is greatly compromised. Also, there is no elements cut for the 3-meter FM broadcast band. You must rely on the VHF-lo elements, which are designed for Mc. This has directional selectivity limitations: Because the wavelength of the signal is too small for the VHF-lo elements, the antenna’s front to back ratio it’s ability to select signals directly in front of it, but reject signals from behind is very poor to nonexistent.

TV antennas tend to have many lobes, scattered around the azimuth plane, looking sort of like a starfish pattern, at Mc. The behavie psuedo omni-directionally at these frequencies. You’ll pick up lots of stations in a metro area or suburb, but you’ll also have a lot of non-local stations with co-channel interference from other non-local stations. For instance, you might be trying to receive a station in Patterson, NY, 23 miles away, but receive interference from a New London, CT station on the same frequency, 72 miles away off the back of the antenna beam.

How to Connect a Stereo System

Turn the coiled wire off the bolt as if you’re unthreading a nut, and clip each lead to about 1cm. Bend little “feet” on the ends of the leads and adjust them so the coil will stand upright. Holding a pair of pliers in each hand, grab the coil’s leads and stretch it evenly along its length until the feet are 12mm apart on center. You may need to even out the coil spacing with a screwdriver or other tool.

This will be your ground plane. Smooth the corners and edges of the ground plane and the pads with a small file.

Jul 29,  · Q: I need an indoor AM/FM antenna for my 30 year-old Technics receiver. It works well enough for the most part, but I have trouble receiving radio on either band.

FM Transmitters This simple mW transmitter broadcasts audio on With good dipole antenna transmission range up to 4km is possible. Frequency is selected by adjusting R1 potentiometer. Transmitter should be powered by regulated V power supply with at least mA current rating. I must really confess that I also favor this broadcast band, mainly because it is so easy to find signals on the workshop radio.

Everyone has an FM radio, and it is fun to play with. Experimental antennas and the like can all be developed in this band since there are a huge range of “beacons” all transmitting just for my benefit: Basic oscillators also are easy to fault-find in this frequency band, and then later modified for other VHF bands. This made the project easy to duplicate and removed “microphony” the ability of coils to act as a microphone with spring-line reverb.

FM Transmitters This tiny Mhz FM transmitter bug measures just 10mm x 17mm in size and as you can see in the photos the biggest components are just the microphone and the battery. You can use a small microphone from an older cell phones, they are small in size and have an excellent sensitivity. For an effective power supply the 9V battery Duracell is excellent and allows several hours of battery life, but if you want to have a smaller size it is better to use 2 or 3 lithium cells like the used in PCs.

The circuit works well from 3 to 12V, the maximum range is obtained with 12V and a piece of cm cable as an antenna. It started with a self-build kit from the Danish manufacturer Jostykit that allowed everyone to build a small FM transmitter for a few Euros. Such transmitters generally consist of a single transistor oscillator with a simple resonance circuit, sometimes with an extra transistor that is used as audio pre-amplifier.

One of the ohm teminals may also be marked 75 ohm, with a line or some sort of marking “linking” it to the ground terminal. The ordinary cheap “T” FM antenna would connect to the 2 terminals marked ohm. Your speaker wire might make do til you can scrounge or buy a “T” antenna. Just take a 6 foot length or so and separate one end of it so the two ends are ” apart when spread out to the shape of a “T”.

Separate the opposite end a few inches, strip the ends and attach to the ohm terminals. Try orienting the “T” in different directions for best signal.

Step. Attach the two wires on the other end of the transformer to the two terminals on the receiver labeled for an FM antenna. Either wire can be hooked up to either antenna terminal for this type of connection.

You can use either an indoor or outdoor antenna, though the outdoor variety often provides better reception. Both types will connect and work in the same way. If you no longer use your antenna for TV, connect it directly to your radio, otherwise you’ll need to use a splitter. Some have a pair of screw terminals, and others use the same threaded F-connector used for cable TV.

Either one will work fine, though you may need an adaptor, depending on your antenna. Purchase a length of antenna wire that reaches this distance. Most antennas have screw terminals intended for flat, two-strand antenna wire. If you’d rather use shielded coaxial cable, purchase an adaptor at an electronics store. Feed the wire into your house through a vent, the soffits or a newly-drilled hole in your wall.

If you drill a hole, weatherproof it with caulking. Run the wire to the room containing your stereo or FM radio. Flat ohm antenna wire attaches directly to screw terminals, and round coaxial cable attaches directly to a cable-style F-connector.

Power Supplies A constant current source source can supply a fixed current to a load regardless of input voltage or load change. The LM is quite useful as a constant current source, works on a wide input voltage range, from 3V up to 40V. The circuit is rather simple, uses only one transistor and few passive components and performs well in terms of frequency stability, almost zero drifting after about 4 hours of continuous operation.

With 12 volt DC it will deliver 1 watt RF power.

This is a pity, because “switchers”, as they are often called, offer very attractive features, like small size, low weight, high efficiency, and low heating. True, they are generally more complicated than linear power supplies, but this is easily compensated by the fact that they can be built for a lower cost. Some early switchers produced an objectionable amount of RF noise, bringing the whole switching technology into bad reputation.
