There are, as it turns out, several ways to do it. Commodore used the same switchbox as Atari, so you may have one laying around or be able to find one in a box of ancient computer and videogame cables. Slide the sliding switch on the box to the top to enable video from the
Recoton Video RF Modulator V Connects one Audio / Video Componeent to a television, Allows the use of DVD players, Video game system, Camcorder, Video components when television is not equippedwith audio video.
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.

It has a plentiful variety of video output composite, S-video, Component and audio output analog, digital optical, and digital coaxial capabilities. However, there is one thing manufacturers didn’t account for: Does this look like the back of your TV? Do you only have a single connection option, the coaxial cable input jack?
The answer to the above questions is a little box that has been around for years called an RF modulator Radio Frequency Modulator. The function of an RF modulator is simple.
Video RF Modulator. Use a Coax cable from the modulator’s “to TV” connector and hook it to a: 4. 75 ohm switch box. (Our “RF Modulator Kit comes with one). It has two coax inputs and one coax output). Hook up the coax cable to the side that has “two” of the coax inputs on the 75 ohm switch box. From the 75 ohm switch box you will need a.
You may already have the parts for one, the other takes an adapter but gives a better picture. The pictures below show you everything. This requires no hardware modification of the system. There are two ways of getting the job done. I’ll describe both, and I’ll save the background info on why this is such a pain for Page 2. The screw lugs are the copper U-shaped thingies at the end of the flat piece of two-wire cable sticking out of the switchbox.
It’s called a ohm matched pair to ohm F-Connector transformer, in technical jargon. All you really need to remember is that it goes from a pair of screw terminals to an F Connector.
Same over all physical size as the stock Atari STM1 mouse except a slightly lower and more comfortable profile with a back end of the mouse which is round in shape Not square with sharp corners! Over the years Atari had about 5 to 7 different manufactures make the same STM1 mouse for them. Each version mouse looks the same from the outside but differs on the inside and bottom locking plate construction.
The RF modulator converts the video (and/or audio) output of a DVD player (or camcorder or video game) into a channel 3/4 signal that is compatible with a TV’s cable or antenna input. There are many RF modulators available, but all function in a similar fashion.
Must pay attention to heat to get results. This has a couple of vents in the image, the one even the S-Video upgraded model for a couple bucks more have NO venting! Nor do they have a power switch. Well like any electronics – it can smoke itself. If you put this in a tight area with no airflow, if you put this anywhere the sun will shine in and beat down on it even for an hour a day – it will die!
They’ll cool down eventually, but their small and heat up because the older F cable technology does that. If you can unplug the 9V adapter when not in use or get it on a switched power strip or plug, you’ll be far happier. It can sit turned on, but if it gets to an overheat point – it’ll blow and you’ll end up taking it back. Don’t bury it in entertainment center holes or shelves with no venting.

Signal Types and Connector Types; Keeping them Straight There was a time, not so long ago, when television hookups were pretty simple. There were two screws on the back of the set, which went to two spade lugs on a ohm twinlead antenna line, and that was it. Apart from plugging the set into the wall and waiting for the tubes to light up, there wasn’t a whole lot else to know about connections.
That all changed with the advent of a series of technologies: Now, instead of video coming into the home and being handled in a single run of twin-lead antenna line, we have a huge assortment of video standards to handle, and a variety of cable types, terminations, and configurations to deliver them.
RF modulators convert the signal from an AV component to a format that is compatible with coaxial cables. Use an RF modulator with your DirecTV system if your TV does not feature the necessary AV inputs to connect it to the receiver.
Differential video signals on UTP cable Normally video transmission is done using 75 ohm coaxial cables, but unshielded twisted pair or UTP cable is a very inexpensive interconnection when compared to a coaxial cable connection. This section gives you circuits for transmitting video signals over unshielded twisted pair wiring. Modern unshielded twisted pair wiring CAT5 or better can be used to transport hogh quality video signals when this is done in the right way. Also lower quality cables will do in the applications where some signal quality degration is allowed for example telephone wire pairs in some CCTV applications.
The secret to sending signals over UTP is to balance them well in order to limit both radiation and noise pick up. This kind of unshielded twisted pair wiring method is used in many CCTV applications nowadays to use existing in-house twisted pair wiring instead of installing new coaxial cable for the CCTV camera. Video signal can be adapted to UTP wiring using a special balun transformer between BNC video connector and the wisted pair wiring.
This converter converts the unbalanced audio signal to balanced signa which nicely travels through the cable. A similar transformer can be used on the other end of the cable to convert the video signal back to unbalanced format which fits to BNC connector. There are both passive solutions balun transformers and active converters available on the market for this application.
Simple UTP baluns just convert an unbalanced coax signal to a balanced signal for use on the twisted pair. Some companies add gain with active converters to extend the distance. There are difference how well different products perfom.

If you do not have either of these connectors, then you will need to purchase an RF modulator from the store where you purchased your Apex Digital DVD player or other home electronics retailers. This cable has three prongs, one each in yellow, red, and white. The yellow prong will go into the jack labeled “Video Out”;
Oct 06, · Right now I have cable going from the wall to the rf modulator, and a coaxial cable running from the rf modulator to the tv, and RCA cables from the rf modulator to the dvd/vcr plugs that say output. So I can play dvds and vhs tapes and they show up on the screen, but I can’t watch cable tv while the vcr/dvd is on- I only get a blue screen Status: Resolved.

Audio Processing incoming links, etc. The Westinghouse 50HG transmitter is a high level plate modulated transmitter. Essentially, the modulator is a high powered 25, Watts , audio amplifier which adds an audio variation to the plate supply voltage for the RF final, modulating the amplitude of the RF carrier.
“I need help hooking up my TV to digital cable, DVD and VCR. I have a RF modulator, but no instructions. My TV is an older set with one cable hook up – the modulator has room for 4 hookups. Please, any help would be greatly appreciated.” This is a problem a lot of people have – with or without a RF.
Sneals ‘s post sounded like it could be done, but I’m gonna guess that a person would have to make such a device, and it would not be readily available to purchase at least at a price I would be interested in paying. The problem is, there’s no market for it. Most current devices that input or output HD video have the appropriate connections for it. Modern HD boxes also have no trouble outputting to SD connections and devices. The OP would be better off springing for an HD DVR from his provider, then dubbing down anything he wants to archive later via firewire.
He’s just have to be sure the box he gets supports it. The other option would be a new component input card for computers that was just shown at CES.

NC , NC X photo above: Note the relocated pilot lamp and the hole plugs covering the unused crystal filter control holes when compared to the NC X header photo. History of the Design and Production – Many radio engineers of the thirties believed that the absolute, best sensitivity and stability of a communication receiver’s RF amplifier, First Detector and Local Oscillator could only be achieved by using “plug-in” coils. This type of approach eliminated problems of lead length, shielding and stability along with isolation of unused tuned circuits – problems that were commonly found in broadcast receivers using conventional rotary bandswitches.
Or, are the problems usually encountered with the BC avoidable by careful set-up and conservative operation? Today, with the ever-increasing interest in WWII military radio equipment, the BC and BC are experiencing a “re-evaluation” and an increased interest in the possibility that these seemingly archaic transmitters can be operated “on the air” without enduring endless criticism of the signal quality – or lack of it. The following web-article tells how to get a BC or BC operational and capable of producing a good sounding signal at an output level that is respectable.
Brief History of the BC and BC Transmitters The BC was designed as a easy-to-operate, reliable transmitter that could be used either in vehicles or in fixed locations. The first AA transmitters were built in the early thirties and used parts and technology from a decade earlier. The BC came about in the late thirties and was an upgraded version that had a better antenna tuner section which added to the versatility of the transmitter. General Electric got a manufacturing contract for the BC and ultimately around , transmitters were built through most of WWII.
The BC set-up for AC operation within a building. Note the interface that allowed “patching” telephone line audio into the transmitter. Also, the CW keys, the T mike and the mill although this might just be a regular typewriter. The receivers are all BC types. On the B , the transmitter was usually located under the radioman’s table while the receiver was on top of the table.
