RCA CRF907A Compact RF Modulator
A simple, branded way to put an older video device on a coax only TV, with a softer picture.
We bought RF Modulator for CATV, M65A-NTSC RCA Coaxial Converter, AV Composite Video to Analog NTSC Coax. It's no longer documented anywhere, so this page reviews the closest well-covered match. It does the same composite to coax conversion and is the long running RCA brand model with retailer spec pages to check.
The short version
- Owners of older TVs with only a coax antenna input
- Retro game players hooking up composite only consoles
- Anyone feeding a VCR or DVD player to a TV over coax
- Your TV has composite or HDMI inputs you can use directly
- You need an HD picture
- You want to send one source to many TVs across a building
What owners like
- Simple way to get an older device onto a TV with only a coax input
- Auto switching saves unplugging the antenna each time
- Long standing model from a familiar brand
Common complaints
- RF conversion softens the picture compared with a direct connection
- Standard definition only, so it is no use for HD sources
- Needs a power outlet for its adapter

What it does
A small box that turns the composite video and audio from a DVD player, VCR or game console into a coax signal on channel 3 or 4; reviewed here in place of the generic M65A NTSC RF modulator it resembles.
- Converts audio and video to RF on channel 3 or 4
- Antenna input passes the regular TV signal through, so cables do not need swapping
- Switches to the video device automatically when it detects a signal
- Works with DVD players, VCRs, camcorders, game consoles and older set top boxes
- Comes with its own power adapter
A simple, well known way to connect an older video device to a TV that only has a coax antenna input. The trade-off is the one every RF modulator has: the picture loses quality on the way through, so it suits retro games, VHS and standard definition boxes rather than anything that needs a sharp image.

Questions
What channel does the RCA RF modulator use?
Channel 3 or 4. Set the switch, then tune the TV to the same channel.
Does the RCA CRF907 need power?
Yes. It runs on a 9 V DC adapter, which is included.
Do I have to unplug the antenna to use it?
No. The antenna connects to the modulator and passes through, and it switches to the video device automatically when it sees a signal.
Will an RF modulator give a good picture?
It works, but some quality is lost when the signal is modulated and then decoded by the TV, so expect a softer picture than a direct connection.
