Don’t tread on anyone!!
I was working the Warren County Libertarian Party’s booth at the local county fair, when I saw the Tea Party’s Gadsden flags. It occurred to me that while the Gadsden flag is pretty good, liberty-speaking, it could be better. Gadsden only covers half of the equation, and could be taken as a plaintive plea for mercy, “Don’t tread on me!”
The more I thought about it, the more it seemed just WRONG. The problem isn’t treading on ME…that’s territorial and isolationist. The real statement is, “Don’t tread on ANYONE.” Let people be. Let them do what they want. Let them live their lives, as long as it has no impact on you living yours.
So I found an image of the Libertarian Porcupine and made this mock-up. It really makes me want to get a flagpole and fly this flag!
I started with a clean copy of the latest version of Raspbian, loaded onto a brand new 8 GB Class 10 SD card. Nothing new there. Things went very smoothly! My hub, keyboard, mouse and wlan USB adapter worked fine. I loaded all of the Raspbian updates, and got fldigi to load without a hitch. Things seemed to be going swimmingly. In Ham Radio, as in life, when things seem to be going too well, disaster is bound to strike, and this was a classic example of that.
I hooked up my Tigertronics SignaLink USB sound card interface, and things started going south. Apparently adding this was a bit too much for the Pi to power, because the keyboard and mouse started behaving very erratically. This was easily solved by switching to a powered USB hub.
To see if the Pi had recognized the SignaLink, I typed:
$ aplay -l
And sure enough, the USB sound card was listed. Cool Beans!
Launching into fldigi, everything looked as normal – the waterfall was flowing down the bottom of my screen, everything was responding seemingly well. We turned on the radio, and started to receive signals into the Pi…and, well, got a bunch of gibberish. Signals appeared OK in the waterfall, but what I received in the text window was…unintelligible.
An hour’s playing around was fruitless. Changing settings in fldigi to match the Pi’s puny processing power, fiddling with settings on the USB interface to optimize the sound to the Pi, twiddling knobs on the radio to adjust levels, and even overclocking the tiny computer to its limits, all proved futile. A quick search on the internet showed that I’m not the only one with this issue – apparently the complexity of the calculations involved is just too much for the Raspberry Pi to handle in its current form.
I’m going to keep at it – but in the meantime, if you’ve had any luck with getting your Pi to work with the Amateur digital modes, please let me know!
This is a good presentation, created by the Libertarian Party of Ohio, introducing what Libertarians are, and what we believe.
I had a number of political conversations over the weekend with people who, upon hearing that I planned to vote for the Governor Gary Johnson, the Libertarian 2012 Presidential Nominee, smugly concluded their side of the exchange saying something along the lines of, “Well, if you want to waste your vote…”
Their voices then trail off. I think it’s because even they don’t believe what they’re saying. I think it’s because, deep down, they know that they couldn’t be more wrong.
