Learning about amateur radio 'ham'


while reading the 2007 arrl handbook, which I freely copied off the occompaning cd from the public library, I noticed that in fcc regulation part 97 station operation standards that it was prohibited to send "false signals, and ciphers" across the airwaves [97.113b] being that this is the paraphrased version and not the original document I can't tell any other details. this perked my interrest in finding out exactly how the government can dictate such a rule when they clearly use transmitted ciphers on a daily basis. I wonder if ham transmissions in the ISM band have to comply with that rule? This is some interresting reading and I plan to get deeper into FCC documentation when I get my next break from work. Seemingly in contradiction a paragraph latter it says RTTY and data (using a specified digital code) may be used when all or part of the communication are transmitted using such an emission.

I personaly become interested in RF through 802.11 protocol but the more I read in this book, I am totally amazed how cool ham is and how little I know. so if you came to this site seeking solid RF discussion, bare with me as I embark on the quest for understanding most of this stuff. I think this summer I am going to look into meeting a lug for Ham enthusiasts and get my licence. Apparently you can get a Technicians licence with minimal effort.

A recent news article on their site said that the morse code requirement is being droped! Great time to get a licence.

I've included a mini glossary because a lot of these terms are new to me. [here]

Another really cool find on the arrl web site was this thing hams do called qsl, where in previous generations hams around the world would exchange these cards proving there communication and receiving awards for stacking up numerous contacts around the world. Now, apparently you can download trusted qsl. which, I might add, uses PKI encryption! I'm finding that these ham people are right up my alleyway of interrests.
