If turning these items OFF is not practical, consider moving your radio away from as many of these noise-generating electronics as you can. Concrete, brick and steel are enemies of radio signal. Naturally, if you have a radio in the center of a building made from these materials, radio reception will suffer. In general, get your radio near a window. For best results, place your radio near a window facing this direction. Then, work on the antenna…. Antennas matter, but almost nobody pays attention to them.

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. You have to trace the circuit to see how the single wire is contrived. It seems most often internal modification is required to use an external 75 ohm antenna.

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. 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.
Aug 12, · Anybody know what kind of adaptor is required to hook-up F connector from cable provider to the Weird FM antenna (75 Ohm) jack on the back of Marantz Receivers.
If so there are several possibilities. First you want to decide if you want an Inside Antenna or an Outside antenna. If an outside one.. Don’t take a chance on a lightning strike blowing up your radio. First a simple 20 foot wire attached to your radio will work and receive stations on your old radio.. Adding a ground wire to the radio will usually improve the signals and reduce some of the noise your hearing. In this next section you will be able to see an inside antenna that works well.
If you can get a long wire up in your attic This is a grid type of antenna that is simply stapled up to the roof rafters in your attic

More than four years of engineering effort have been devoted to this one design with two specific goals in mind:
Feb 10, · Trying to make an fm antenna for my stereo receiver. Not sure of what to use exactly! Speaker wire, solid copper wire or? Also need to know what leads go to where on the fm connections. Thanks much for your time and : Resolved.
It accepts a stereo audio source and outputs a stereo FM broadcast signal on the frequency shown on the LED display. It comes just as shown in the picture above. It is rated at 30mw that’s milli-watts of transmission power. For most Christmas DIYers this is a nearly perfect amount of power. Why is this good? Skip to this section for more details:
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.
Si FM Radio Receiver Hookup Guide; Share on Twitter Share on Facebook Pin It. Introduction. Heads up! This tutorial was written for Si FM Tuner Evaluation Board V The V and GND pins are switched in the new revision. The board does not have a built-in antenna on it. However, by using headphones or a 3 foot-long mm audio.
Antenna hook up If you are using an indoor Antenna: Indoors all houses are affected by the running electrical circuits which in turn generate magnetic field that together with the structure of the house obstruct or weaken the wave signals of wireless and TV reception. Also this issue may be aggravated by the vicinity you are live in. Where you are living may not have the optimum reception from some services including TV signals. Your best bet is to try moving the Indoor antenna closer to the outside such as windows, or better to a balcony and try all four directions of the house.
This problem can be detected by trying another antenna that is working good when used with another TV and preferably at a different location thus testing for the possible weak signal at the same time. This may have a problem of some element of it disconnected internally on the board or de-soldered.. If the Antenna is external, all the above points are still valid, but the probability is higher, for some hidden disconnection on the receptacle, the antenna plug or at the connection of the co-axial cable with the external antenna.

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. The frequency of the oscillation depends on the values of Ll and CV1, so that varying the value of CV1 tunes the oscillations to the exact frequency required.
In order to achieve a high output level, you will need a well tuned antenna, and a large heatsink to dissipate the heat from T2 transistor. Transmitter was mounted in metal enclosure and works extremely well. Frequency adjustment is accomplished with MV varactor diode and R7 10K potentiometer.
How to Hook Up a TV Antenna: 9 Steps
On August 9, at I used to keep stacks of these in my toolbox they conveniently press together. Beware, they have two that appear nearly identical
Feb 17, · Most antennas don’t come with the cables that connect your antenna to your FM Receiver. If you are in doubt what cables you need, again, ask your local Radio Shack expert. The diagram below depicts a simple hookup configuration. Computer inputs, tuner inputs, antenna connections, as well as Antenna and audio cables are all.
Made by Winegard Antenna Experts Leading US designer and manufacturer of quality antenna and signal reception equipment since Why do I need a Boost amplifier? The Boost amplifier helps pick up channels that your non-amplified antenna alone may not be able to pick up. Additionally, the amplifier minimizes pixelization and drop-outs. Does the Boost amplifier work with any antenna?
Does the Boost amplifier have an FM trap? What parts are included with the Boost amplifier? What is the noise figure of the Boost amplifier? The Boost amplifier has a typical noise figure of 1 dB. How do I set up the Boost amplifier? If plugging into a V adapter, then plug the V adapter into a V outlet. Run a channel scan. When do I need to run a channel scan?
How to Make an FM Antenna
Weather What type of feedline coax should I use for my antenna A common question that I receive is what type of coax cable should I use for my J-Pole antenna. This is a great question, as the coax you select can make a dramatic difference on the performance and range of your antenna system. There is a wide variety and choices of coaxial cable available and each type serves a different purpose. All coaxial feedline cables will exhibit signal loss.
The selection and installation of an appropriate FM antenna is arguably the most important aspect of receiving high quality FM broadcasts. No single antenna type, whether indoor or outdoor, is perfect for all receiving situations.
It does not matter if you have a CD loaded to enter this mode. Press service again and you get an antenna connection indicator. Another press shows signal strength, e. You can change stations and bands. Press again and you get a signal strength bar. Next Press shows MP: In AM mode no indicator numbers are shown. In FM, a number appears in brackets after the MP: Next press put the radio back in “normal” mode.
I saw a suggestion that the root of the problem may be at the base of the antenna. I was able to get under the headliner by removing the retainer which is right at the top in the wagon opening. One can then see the nut and wires that connect to the antenna.

If I connect the shield of my coax which is grounded outside to the antenna input of my R8, I hear lots of junk, indicating that there is an RF voltage difference between the coax shield and the R8 chassis. Last night this measured about S5. That’s a lot of noise: This sort of disagreement about ground potential is characteristic of electrically noisy environments. The receiver will, of course, respond to any voltage input that differs from its chassis ground.
The antenna, on the other hand, is in a very different environment, and will have its own idea of what ground potential is. If you want to avoid noise pickup, you need to deliver a signal, referenced at the antenna to whatever its ground potential is, in such a way that when it arrives at the receiver, the reference potential is now the receiver’s chassis potential.
Coaxial cable represents one way to do this.
