49MHz Part 15 re-re-visited? Still usable, today.

Boomer FWR me this:   http://kdxradio.com/gallery_files/Brownwood_Bulletin_Fri__Nov_18__1977_hobbyist.pdf A 1978 article on 49MHz Part 15 band. And then, this VID: https://www.youtube.com/watch?v=sPf6_v21xds     WOW!!!! Does all this bring back memories of 49MHz stories of, walkie-talkies, cordless phones, and baby monitors. Certainly, made it worth having a scanner, with a good VHF Low antenna, in the 1980īs. (Hi-hi...) Still, this band could be great to use, now. Like this dude did:  http://www.fordyce.org/scanning/scanning_info/babymon.htm      Years ago, Iīve audio modified a Safety dual-channel 49MHz Baby Monitor, 49.850MHz and 49.870MHz, NBFM. I went a step further by adding a POT for audio adjustment and an extra resistor, in series. (Like 10k-Ohm, or higher.) And??? As a bonus, this Baby Monitorīs transmitter came with a built-in audio ALC unit that was really effective. Audio wise??? A little better than telephone-like, really. Then again, if you are going to use scanner radios to receive this, hi-fi audio quality isnīt a concern.

Recently, a co-worker quizzed me on, "What would happen if you were to apply reverse polarity to the Energizer Bunny?". Having no idea, I asked, "What would happen?". The answer is he'd keep coming and coming and coming...
