Data transmitted over Amateur Packet Radio is not permitted to be
encrypted. Larry.... it is "encrypted" in a sense. Otherwise my scanner should be able to recieve it no different than the voice comm's I already hear there. It is "encrypted" (or maybe a better choice of words being "encoded") in the sense that it needs to be encoded before sending over the air and decoded at the other end. And this is totally legal as long as the standards and such are publicized. Look at PSK31 and the 15-20+ other variations of the digital modes, are you now saying all of those modes are illegal? When was the last time you listened to a packet signal being transmitted and could tell what was being sent as far as the content of the message, merely by listening by ear? If you are that good, you have my respect, as it merely sounds like a digital "blurb" to me. Now do you understand what I meant by "encrypted?" The average "public" in "scannerland" does not have the capability to monitor that traffic as we do. -- Ryan, KC8PMX FF1-FF2-MFR-(pending NREMT-B!) --. --- -.. ... .- -. --. . .-.. ... .- .-. . ..-. .. .-. . ..-. ... --. .... - . .-. ...

Injuries, triage info, fatalities are information that *may* have to be passed as traffic and need to stay in a mode that is not generally accessable to every nut (or media person) with a scanner. Packet, albeit slow is okay for this, as it is a legal means of encrypting the data. Ryan: Data transmitted over Amateur Packet Radio is not permitted to be encrypted. Equipment to receive and decode AX.25 packet radio is widely available, even to the news media, so that is not what I would consider to be a legitimate concern. Any mode used by hams to transmit data over the air must be considered to be wide open to monitoring by anyone capable of acquiring the off-the-shelf technology necessary to receive it. 73 de Larry, K3LT |

The same way that messages sent in Morse Code are "encoded". Perfectly legal. When was the last time you listened to a packet signal being transmitted and could tell what was being sent as far as the content of the message, merely by listening by ear? If you are that good, you have my respect, as it merely sounds like a digital "blurb" to me. The old-time RTTY techs could read certain combos by ear, having heard them so often, just as many of the international point-to-point radiotelephone techs could "read" inverted speech after being exposed to it long enough. Just like high-speed Morse..... Now do you understand what I meant by "encrypted?" The average "public" in "scannerland" does not have the capability to monitor that traffic as we do. They sure do. TNCs are cheap, and an awful lot of "scannerists" have them if they have any interest in HF reception. Some of those TNCs can decode protocols that the average ham TNC can't. Of course, when the material is decoded, it usually turns out to be "spook" quality encrypted. -- 73 de K2ASP - Phil Kane |

Ryan: I didn't say that at all, and you, yourself, stumbled on the truth: Amateur Radio digital modes are "encoded," not "encrypted." Encryption implies that a system is being utilized to obscure the meaning of the message to all who do not possess the requisite decryption equipment and "key" to the encryption method utilized. The "encoding" methods utilized in Amateur Radio are public domain, and the equipment used to decode these signals simply MUST provide positive and accurate decoding in order to work -- or else, nobody would spend good money to purchase them! "Encrypted" signals have no use in the ARS -- and the FCC rules which prohibited encrypted signals is quite correct considering the nature of our service. When was the last time you listened to a packet signal being transmitted and could tell what was being sent as far as the content of the message, merely by listening by ear? If you are that good, you have my respect, as it merely sounds like a digital "blurb" to me. Never, of course. However, while operating RTTY, I can recognize my own call sign being sent in Baudot code! Now do you understand what I meant by "encrypted?" The average "public" in "scannerland" does not have the capability to monitor that traffic as we do. I was never confused over the meaning of the term "encrypted." Moreover, the average public scanner owner can, indeed, decode packet signals for the price of a TNC. This does not imply that packet signals are "encrypted" in any way. If you thought otherwise, perhaps it is you who is/was confused! 73 de Larry, K3LT |
