How I would like to change the cell phone industry [was AM electromagnetic waves: 20 KHz modulation frequency on an astronomically-low carrier frequency]
"Bob Myers" hath wroth:
"Radium" wrote in message roups.com... One thing that I do like are the sharp sawtooth wave patterns that show up on FM video receivers whenever lightning strikes. When, pray tell, have you ever seen an "FM video receiver"? Bob M. I have one of those FM video receivers. It's my (ancient) Wavetek 3000b communications service monitor, which displays all kinds of nifty light shows and patterns for FM. I often tune it to the WX channel and watch the modulation on the scope display. It's kinda hypnotic without the accompanying audio and sometimes an improvement over what's available on TV. I guess it's TV for radio geeks. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
