Field Day 2004
pa3gvr writes "This weekend many Amateur Radio operators (HAMs) throughout the US and Canada will take their equipment to public parks, campgrounds and Emergency Operation Centers. With all the coverage that BPL has gotten lately it might be interesting to see what this Amateur Radio thing actually is. Field Day is setup as an exercise for HAMs to test their readiness and ability to operate under less than ideal (emergency) conditions. Besides the training and exercise aspect, this is also a social event. Visitors are welcome to have a look and maybe even operate some of the equipment. K4FAU, Florida Atlantic University ARC and Boca Raton ARC will be setting up their Field Day station on the Boca Raton, FL FAU campus."
BPL= Broadband over Power Lines...
Which all users of RF technology of any kind consider a boogyman unknown because power lines weren't meant to carry any sort of signaling at all and therefore are completely unshielded. It's just plain a theoretical nightmare if this technology were to be widely deployed... nobody's quite sure how bad the problems for other applications would be.
This may be a nothingness, or it may be the death of ham radio depending on who you listen to.
A good line from ARRL is at:

Seems wireless internet would be far cheaper and more effective. Plus, some BPL solutions rely on 802.11 for the last 25 feet or so.
I don't know, but it works for me.
I think it's been shown in an official comment or ruling by the FCC that encryption is not wholly illegal on ham radio. The wording of the rules states that amateurs aren't supposed to obscure the meaning of their communications.
;-) states that it's okay to use an encoding for authorization. So you could check your IMAP email over ham packet if you used the CRAM-MD5 method of authentication. You wouldn't currently be allowed to use SSL for the whole session, but CRAM-MD5 allows you to authenticate with a shared secret without exposing the secret over the air.
The specific ruling that I am too lazy to look up
Not to mention when the phone system and satellite phone goes down. Impossible you say? Recall the LA fires of last year: no cell (towers burned town), regular phone didn't work (switching stations burned, and overloaded) and overloaded satellites. What was left? Ah, the obsolete HAM radio.
I don't know, but it works for me.
Sec. 97.113, paragrah (4):
(4) Music using a phone emission except as specifically provided elsewhere in this section; communications intended to facilitate a
criminal act; messages in codes or ciphers intended to obscure the meaning thereof, except as otherwise provided herein; obscene or indecent words or language; or false or deceptive messages, signals or identification
One-time passwords and challenge/response authentication are indeed used in some ham applications. Many hams have a knee-jerk reaction to any mention of cryptography, though, so be prepared to quote chapter and verse. The key phrase there is 'intended to obscure the meaning'. You're not obscuring any information, just proving who you are.
