I’ve updated a few of things. There is a direct download or play link just below the Flash Player for devices not compatible with Flash. Be aware it is a large amount of data and there can be buffering, but you can download the file. There is a new picture of the Funcube Pro Plus dongle and I replied to the last comment from Emily Taylor, which explains what my main interest is now. I can assure you they are not fishing and hunting!

Here is my recording of a baby room monitor using a software defined radio. It was recorded from inside my living room using my discone antenna, Airspy, and SDR# (SDRSharp). Video and audio were captured with Daum Potplayer at a true 16×9 resolution of 848 by 480 pixels.
I thought by now everyone using baby room monitors would have moved away from 49 megahertz analog technology. Reception is noisy because of a somewhat weak signal and humming sound, possibly a fan blowing on the microphone. Maybe that fan was upsetting the baby. Also note, I neglected to show the waterfall display on the video itself, and the tuning was off by .016. My fault.
Notice the waveform for the selected signal (49.830 megahertz) is more pointy compared to the video.This happened after I stopped recording.
