Nope, I'm not gonna talk about relativity. I just like that little ditty. Gonna talk about something else.
Most amateur radio operators use UHF and VHF FM to chat with other hams in their own community. These frequencies aren't intended for long-distance communications, but are quite effective, and fun, for localized nets and chatting. One downside? It's line-of-sight communications.
That means, if there's stuff ... be it buildings, a forest, a mountain, etc ... between us, I can't talk to you.
Not radio to radio, anyway. That's simplex operation.
But we can extend communications considerably with a REPEATER.
[I'm gonna be hanging out with friends from Friday until Monday, so instead of vegging in front of the computer, I'll be sipping wine, swapping lies, laughing myself silly, and playing games for the next four days. (Thank goodness for auto-posting!) Sorry I won't be visiting any of your blogs, but I always appreciate the great comments you guys and gals leave here, and will respond to them asap. Seeya next week!]
