    NOW, the rule explicitly defines the "mode" as "1A0", and explicitly says it has to be "plain text". It doesn't quite go as far as stipulating morse code, but I think I read a non-binding FCC opinion someplace where they basically said occasional adhoc prosigns are OK as long as they're published SOMEWHERE and your intent isn't to conceal what you're sending, but hex-encoded UTF8 and any kind of binary-encoded file is absolutely beyond the pale.

    You are quite incorrect.

    In the definitions: (1) CW. International Morse code telegraphy emissions having designators with A, C, H, J or R as the first symbol; 1 as the second symbol; A or B as the third symbol; and emissions J2A and J2B.

    Nowhere does it say it has to be "plain text". There are restrictions on the code used (International Morse Code, 5 level Baudot, etc...), and restrictions on the content, but "plain text" is not one of them. Perhaps you are thinking of 97.113(a)(4) which prohibits: "(4) Music using a phone emission except as specifically provided elsewhere in this section; communications intended to facilitate a criminal act; messages encoded for the purpose of obscuring their meaning, except as otherwise provided herein; obscene or indecent words or language; or false or deceptive messages, signals or identification; "?

    UUencoding is not an encoding for the purpose of obscuring the meaning of a message. If you encrypted those files before uuencoding, then you would be breaking the rules, but otherwise, no.

    As for sending binary files being "beyond the pale", sorry, still incorrect. There is an international network of packet and pactor based systems that do this on a regular basis, using an encoding that is much more obscure and complex than UUencoding. It's called Winlink 2000. It is, for all intents and purposes, an extension of email to ham radio, and you can send doc and pdf and all kinds of binary files as attachments to those email messages. There is no FCC rule prohibiting this.

    As for your recollection of the old rules, I recall nothing that would have been a hot-button issue for the FCC in sending files via computer-generated CW, as long as the control op was sitting there controlling it.

    In a way, I can see why they clamped down a bit. At the time I didn't have the RF or digital electronics background to know it, but I now know that turning a carrier on and off is neither instantaneous nor consequence-free, and when you do it fast enough, you're basically bit-banging de-facto AM via PWM and square-wave artifacts that's going to splatter over a MUCH wider chunk of spectrum than a carrier being slowly turned on and off by a straight key.

    What you call "splatter" is what we technical people call "bandwidth". Yes, a 200 wpm CW signal has a higher bandwidth than a 10 wpm signal, but I don't seem to find any limit to the CW speed being used. I do find a limit of 300 bauds for data, but I don't believe that applies to CW. There were, and probably still are, people who manage 60 to 80 wpm manually. There is a woman who has a record more than 1700 wpm using software.

    As for how fast the carrier is turned on and off, that is a function of the TR switching in the transmitter. You can have bad key clicks at 5 wpm, too.

    A library's goal is to provide knowledge to those who seek it, regardless of means.

    That points out the difference between "book larning" (for a very very broad definition of "book") and physical practice.

    If you think that "physical learning" is a library's intended purpose, then why don't libraries have soccer fields attached? And then expand that to football (oblong ball) fields. And basketball courts. And handball courts. And automotive shops. And chemistry labs. And racketball... well, I think you get the point, I hope.

    Physical practice in how to build something is NOT the purpose of a library, and it never has been. "Here's the information, go out and use it" is. It has nothing to do with the means of the patron.

    Or perhaps by scared people of means who also want to keep the poor in their place - how dare they try to improve their lot and possibly compete.

    If you are going to put words in other peoples' mouths, then you aren't really looking for a discussion, are you?

    Not expanding the public library into a place for every kind of activity anyone might possibly want to engage in has nothing to do with "keep the poor in their place". It has to do with intended function and reasonable goals. Not wanting fully-functional welding and machine shops at every public library doesn't mean that public facilities like those don't have a place or function, somewhere. Even feeding poor kids whose parents cannot afford to has a place, but it isn't the library.

    Personally, I'd love to have a machine shop I could rent time in (and no, I don't expect it to be free, and I don't expect the taxpayer to pay the rent, because the use would be for a more limited audience and the costs for maintenance would be much higher) to do simple things. I just don't think the library is where it belongs. There is no argument that doesn't start from incorrect assumptions that results in a requirement that it be at the library.

    The argument that "libraries are supposed to spread knowledge and anything they do that furthers that is good" is erronious. It leads to nonsense like "well, a well rested person learns better, so let's provide cots and three hots for free..." or "driving to the library helps people get there to learn, so let's loan out cars...".

Not just poor kids, any kid that walks through the door will be fed for free. Well, at taxpayer expense, I should say.
