[GTALUG-Announce] January Meeting Reminder
*Speaker:* Chris Sullivan *Topic:* Radio Direction Finding with the Raspberry Pi *Date/time:* 2022-01-11 T19:30:00 *Location:* Virtual - Big Blue Button (link below) *Topic description:* Home-brew pseudo Doppler radio direction finding systems are typically based on discrete components. Much of the hardware complexity can be replaced with a software design, using minimal external components to the Raspberry Pi. This can dramatically lower the cost of implementation, provide additional signal processing capabilities, and provide remote control capabilities that permit the coordination of multiple units for instant triangulation. *We're going to use Big Blue Button for this meeting: * https://blue.lpi.org/b/eva-zjc-gjy-kgl *A*lan *H*eighway <http://heighway.ca/> heighway.ca VA3WAH / VA3YKZ [image: Please consider the environment before printing] --- GTALUG Announce mailing list announce@gtalug.org https://gtalug.org/mailman/listinfo/announce

Hmmmmmmm - - - - so I need to sign up for an account at this location to participate? Will this work on my tv (used for streaming)? (FAQs do not indicate) TIA

No, you simply type in a name ( any name does not have to be your real name ) then click 'start' and it will connect you to the conference. You do not have to sign up for anything.
Will this work on my tv (used for streaming)? (FAQs do not indicate)
If you are able to see what is on your computer screen on the tv then yes you should be able to.
TIA

From my experience using BBB for other events, a new account is not
required. Just give a name to label yourself for interactions. As far as your TV, it runs in a browser, no plugins or programs required. If you're using a browser on the TV itself, I have no idea if it would work. I've used Firefox and Chromium based browsers without an issue. --murph

| From: o1bigtenor <o1bigtenor@gmail.com> I got two copies of this message from o1bigtenor. Once last Tuesday, and once today. Odd. The message I got today included these two chunks in the header. | Received: from penguin.gtalug.org (localhost [127.0.0.1]) | by penguin.gtalug.org (Postfix) with ESMTP id 5086AE60A; | Sun, 9 Jan 2022 10:43:45 -0500 (EST) | Received: from mail-lj1-f181.google.com (mail-lj1-f181.google.com | [209.85.208.181]) | by penguin.gtalug.org (Postfix) with ESMTPS id DD9E8E383; | Tue, 4 Jan 2022 07:04:25 -0500 (EST) It looks like it has been sitting in a queue on penguin for most of the week. Did anyone/everyone else get two copies of this?

Yes. Same as you. One a few days ago, and one today. -- Znoteer znoteer@mailbox.org

Great question. Your message contains quoted text. It sure has odd stuff: The first quoted line is:
*Speaker:* Chris\303\202\302\240Sullivan
The \ followed by three octal digits represents a byte with the high bit on. In ISO 8859-1, these mean: \303 LATIN CAPITAL LETTER A WITH TILDE \202 invalid [in Control Character range] \302 LATIN CAPITAL LETTER A WITH CIRCUMFLEX] \240 NO-BREAK SPACE That's nowhere in the copy of the announcement that I received. That text comes in two forms within the original mailed announcement: - plain text, in UTF-8, but with no bytes with the high bit on. So plain ASCII. Looks simple and fine. - HTML, in quoted-printable UTF-8. This is where the problem lies Here's the second line in the raw mail: <div dir=3D"ltr"><div style=3D"color:rgb(46,46,46);line-height:19px;white-s= pace:pre"><div style=3D""><font face=3D"arial, sans-serif" style=3D"" size= =3D"4"><b style=3D"">Speaker:</b> Chris=C2=A0Sullivan</font></div><div styl= e=3D""><font face=3D"arial, sans-serif" size=3D"4"><b>Topic:</b>=C2=A0Radio= Getting rid of the quoted printable bits (= stuff) and adding harmless line breaks: <div dir="ltr"> <div style="color:rgb(46,46,46);line-height:19px;white-space:pre"> <div style=""> <font face="arial, sans-serif" style="" size="4"> <b style=""> Speaker:</b> Chris=C2=A0Sullivan</font> </div><div style=""> =C2=A0 is one character in UTF-8. 1100 0010 1010 0000 It stands for UNICODE 1010 0000 which is Non-breaking space. SUMMARY: The original message looks OK to me. Your MUA or maybe MTA have probably screwed up. Barracuda? Thunderbird?
