What RF Modulator do I need [Archive]

February 26, Author: The results were mixed, the picture was significantly better then it had been, but it still suffered from interference. Two chaps who like me, were not happy with the picture quality of their and wanted to offer a better solution to fellow Atari enthusiasts. Thus was born the PureVideo board, a professional looking, easy to install mod, compatible with the Six switcher woody to the Atari Junior. They make using a modern flat screen telly a painless experience! I caught up with the pair last year and pick their brain about the PureVideo module and story behind it.


The peripheral was initially announced in , planned for release in , and repeatedly delayed until its release in December It launched alongside a now defunct online service called Randnet. With nine games released, it was a commercial failure and was consequently never released outside Japan. It was bundled with the 64DD’s launch title, Mario Artist: Paint Studio and manufactured by Mitsumi.

Feb 14,  · Then I tried to hook it up to the Sanyo with an RF modulator, and I’ve got nothing. The light on the RF modulator won’t even come on. I even tried to buy a new modulator .

I have Knology cable and that cable box has a dvr. I also have a RF Modulator if need be. I do not want to have to unhook I do not want to have to unhook things and rehook up things each time I use it. Could someone walk me through how to do this? I would like to do this very soon because I have no room to record any more stuff and I am trying to tape all of the hockey games. And the Stanley Cup starts on Saturday so I need more room!!

I hooked it up like mikedamirault suggested but it isn’t working. Though thank you for the very good directions maybe I am missing something?? Here is what I did and what is now happening: I added the RF Modulator between the tv and cable box. I took one set of the composite lines from Out

How to hook up your Video RF modulator.

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.

For your convenience this document provides the four most common hookup Connect the coaxial cable from the wall to the RF IN jack on the set-top box. Note: Your TV must have two composite A/V jacks to use this hook-up scenario. (2) Composite A/V cables (2) S .

Check new design of our homepage! Understanding What an RF Modulator is and the Purpose it Serves Signals sent from a television station to our TV’s antenna, travel long distances without losing any data. They do this by getting their frequency modulated, with the help of an RF modulator. Read on to learn more about this device. Techspirited Staff Last Updated: Aug 30, Radio frequencies lie in the range of 3 to GHz. They serve as carrier signals, in the process of modulation, for electronic devices.

What exactly does modulating the signal involve? Transmitting a signal over a long range, may cause it to suffer a large number of losses. The signal that ultimately reaches the end, is damped to a large magnitude and ends up losing a lot of information. The solution to prevent such loss: The process of modulating the signal, means mixing the signal with another wave of a higher frequency.

This reduces the losses caused during the transmission of waves over a long range and the distance traveled by the wave can be greatly increased.

Reply Thu 27 Dec, The modulator goes together pretty quickly the benefit of no moving parts , and after running the 75 ohm connection from the converter box to the TV In connection and the 75 ohm connection from the TV Out to the TV , along with the RCA cable connections from the DVD player to the modulator and plugging in the power adapter , a test of the installation initially suggested we were still not quite there – since the DVD was successfully transmitting audio, but not video.

A quick re-review combined with a little intuitive deduction, based on the fact that audio only was now working , revealed that although the rear connectors of the DVD player were “color-coded” for standard RCA-type connectors white, red, orange , as was the modulator unit, it was necessary to plug the orange cable on the DVD into the Video Out plug, which was grouped with the Component Video connectors Who knew?

The Composite Video Input can be used to hook up a DVD player, or other Composite Video Device, and send the signal to all the RF outputs via the built in Video Modulator.

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. With that setup, you could edit out commericials and excess video on each end of a program, then output to the deck via firewire.

Either of those options is obviously a tough workaround, but I don’t see any other real options if the deck won’t do a timer record over firewire. I don’t foresee anyone supporting HD to RF converters at this point – especially when it mainly would benefit an essentially dead video format.


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.

An RF signal is analogue and a modern TV has to be put into ‘analogue mode‘ in order for it to be tuned. Then you can usually allocate a channel and set it to auto-tune. If auto-tuning skips past the signal (usually Channel 36) then you may have to set it to manual tune.

Setting up an RF modulator is fairly straightforward: Each picture also links to a larger picture of the diagram and more details on the wiring involved. A camcorder or video game or satellite receiver should work. Then there are video switchers with a RF modulator. Alternate diagram below adds a VCR. For manually operated boxes, select the button matching the input of the component you want to use. The one powered on. Sunday, December 19, – These devices have the capability to switch between multiple input components and output to channel 3 or 4 via the modulator.

More advanced systems are possible, such as front projection systems which would likely add a line-doubler between the DVD player and the projector or an HDTV capable display with a separate HDTV tuner, but this gives you an idea. DVD Player and Television: The function of an RF modulator is simple. Basic standard RF Modulator hookup diagram: Usually white and red RCA cables.

The last diagram is of a more advanced home theater system, with a large number of components.

RF modulator and DVD install Questions

Share on Facebook Outmoded home electronics still have a lot of entertainment potential, from vintage video game systems and VCRs, to elderly television sets. Getting them to work together can be an interesting exercise in nostalgia, often requiring the use of oddball pieces of equipment such as RF modulators.

These were common in the s and early s, permitting the use of newer technology with older television sets. Most have only one or two types of simple inputs.

(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.

Automatically switches from TV to connected component when power for that component is turned on. I have radically changed my position. I the older versions of these things appear to be in almost every second had store for just a few bucks, and NOT just mono versions, but stereo ones too. Allowing any text to be read, and keeping the proper dimensions for the image. And probably the best you’re going to find. On the Plus side: Convenient if you’re watching on an old TV, which I think is their assumption.

I have a very old TV for my daughters room that only has once plug in the back that happens to be a Coaxial connection. I decided to put our old original Nintendo games to use and bought a new system to use with the old games, however it only used RCA connections. After much internet searching I found this product. This product really helped me, not only did it allow me to hook up the game system to a practically useless TV but will also allow for VCR or DVD to be connected as well.

Also, it was also very reasonable priced compared to some of the other converters I saw. Definitely recommend to anyone in my sort of situation.

Is there a device to hook an Atari to an A/V input

Take a deeeeeeeeep breath. First off, turn off all power to all device involved here. Never kerfutz around with this stuff while it’s powered up. It might stop working. Then, forget what you have going now.

Sep 28,  · You can connect a Roku 2 (Not a Roku 3) but, if there is no composite connection, (red/white/yellow RCA) then you will also need an RF modulator.

I’ve tried hooking up a 5V 1A power supply with the ground wire hooked to the modulator’s chassis. I also tried a variety of other connections, but couldn’t get anything to display. What are the other pins for, and what should I do to get this thing working? Reason for doing this: I’m aware that I can buy an RF modulator, but I’d like to try this out first.

From a completely naive standpoint meaning, lacking a datasheet, you can take this approach: Connect to -ve or common terminal of your power to the shield of the modulator. Touch the positive lead to each pin until you get a blank channel instead of snow. Do the same for audio and video signals until they go to their proper pins.

The then unused pins are grounds.

Next It seems as if every home garage across the country has an old, unused TV set sitting inside. People don’t use them because they think that they can’t use today’s technology — including VCRs, DVDs , MP3 players, camcorders and gaming systems — on the old set. With a radio frequency RF modulator, it’s all possible. The modulator converts the picture and sound coming from your DVD or gaming system and displays it on the old TV screen [source:

How to Hook Up an RF Modulator With DirecTV. Select either the channel 3 or 4 output on the back of the RF modulator. Setting up an RF modulator is fairly straightforward: Each picture also links to a larger picture of the diagram and more details on the wiring involved.

Low contrast and brightness 2. Lower contrast and brightness 3. Very low contrast and brightness 4. Possible picture roll 5. Slight loss of color 6. Possible loss of color 9. Probable total loss of color Table 2 shows that there is a very serious loss of high frequency response as the Twisted Pair wires extend beyond a few hundred feet. Obviously something must be done to be able to obtain high definition pictures at more than a few hundred feet, especially when color is to be carried.
