RF Demodulator Coax to HDMI UHF Modulator VHF Adapter Coaxial Converter for JVC Videodisc Betamax VCRs VHS Camcorder Video CD Player Magnavox Odyssey Atari 2600 to HDTV HD Digital Projector Monitor TV

Worked as advertised, providing a way for me to use my old RF-based video game consoles on my HDTV.

Does not work. I wanted to hook my old atari up to a newer tv. After searching forever and only finding modulators I finally came across this demodulator. There are no instructions with the unit. other than a piece of paper that says what each button on the remote does, and a on a very small piece of paper 3 "troubleshooting" steps. Which are not actually troubleshooting steps. I attempted to scan for a signal multiple times in multiple ways. I tried with 3 different Atari's connected, a woody, a vader, and a Jr. and it found the signal on none of them. In the end I may need to mod the systems with a composite board since there are no other demodulators I can see. For the record the Atari's work just fine when passed through my older surround system that has a 75ohm rf connector. But that unit is huge and I don't want to use it.

Did the auto scan with my Atari 2600 turned on as suggested by other reviewers. It picked it up and programmed a channel for it no problem. However I'm giving it 4 stars instead of 5 because it was unable to pick up my Famicom. Maybe if I messed with it more I would be able to get it to work but I didn't mess with it much because I have an AV Famicom that I can pipe into the system by other means.

It works great and setup was easy. All I had to do was plug it in, change the TV to the right input, power on the device(an Atari 2600 for the first try), press the menu button, and find the auto scan option.My only issue has been a very faint scrolling static line from EM interference but that could be from several things like the WiFi in my house, a shielding issue with the console, or a shielding issue with this device itself. I have to look up grounding/shielding options to see if I can eliminate it.

This thing is a piece of crap! It is not easy to use, it does not work period!

Got it working within 5 min with the help of other reviews here.You have to have your system running (mine was atari 2600), and use the remote to auto scan the channels. It will automatically find it while scanning every channel.

I was able to get this working on channels 2, 3 and 4, as needed for a few old devices. I set each channel and manually tuned each with a working video source, that seems to be the easiest way to set it up since I'll never have all 3 channels on at once for auto tuning.The video output is a bit noisier than my television can do alone, and the RF connector seems to wiggle a bit so I'll probably need to re-solder it. Overall however it's inexpensive, does what few confirmed working devices do, and most importantly for me will plug into small HDMI monitors which lack NTSC tuners.

It doesn't work. Technical support is in China, so you can't talk to a human. I'm sending this back.
