confuzzled: fldigi seems to be interfering with itself …

Fldigi used to work fine, but recent updates may have caused me to drop off the face of the (radio) earth. What it seems to be doing — and I don’t find this at all plausible — is causing interference with its own audio stream when its window has focus, but receiving perfectly when the program window is hidden. As Fldigi is a highly interactive program, this is not much use.

Here’s an audio sample showing what I mean: fldigi-psk14070-VA3PID-201206092107z. It’s about 45 seconds long, a sample of the 20m PSK31 band this afternoon, and comprises:

  • 0-15 seconds: fldigi’s window is in focus. None of the traces in the waterfall resolve to meaningful text.
  • 15-30 seconds: I changed focus to another program. The waterfall traces snap into focus; QSOs become readable. The conversation at 2383 Hz goes from line noise to a very clear “…  73 73  Jim and thanks for ans[w]ering the cq …”
  • 30-45 seconds: fldigi’s window is back in focus, and all decoding is cut off.

I’m running fldigi 3.21.43-1~kamal~precise from the Ubuntu Amateur Radio Software Updates repo. Hardware is a Thinkpad R51 (a bit old), latest Ubuntu 12.04 LTS, a FT-857D into a Signalink USB, and the audio’s being handled by PortAudio. I’m stumped!

Update: It was a volume thing. Linux had decided that I didn’t need my main system volume above 10%, so fldigi was picking up noise only.

you say homage, I say ripoff

Can you tell the difference?

gone with the wind

I see that Americas Wind Energy updated their website to replace the site I wrote for them a couple of years back. It’s purty, but:

  • The page URL sometimes inexplicably switches to d3095932.ejt86.ejtechinternational.com from awe-wind.com.
  • The product page for the AWE 52-750 shows a bunch of non-operational turbines.
  • The AWE 52-900 page also has a picture of a parked turbine, and it looks a lot like Tallon Energy’s 52-750 at Pincher Creek.
  • More parked turbines on the 54-900 page, and occasionally a completely different machine is shown.

Oh wait, I get it – it’s a random turbine image for each page. Hmm.

This wind study brought to you by the Canadian Nuclear Association

So there’s a new report on wind integration in Canada, written by The Conference Board of Canada. People are picking up on it, and even the doughty Refocus quotes… electricity from onshore wind is uneconomic in comparison with traditional alternatives“. Hmm.

So I read the report, and what do I find in the Preface?

As part of an ongoing initiative to investigate energy policy options and the future of the Canadian energy system, the Canadian Nuclear Association contracted The Conference Board of Canada to conduct a comparative study of various countries’ experiences with supporting and implementing large-scale wind projects.

So we’re expected to believe that the CNA would wish to have an objective and non-partisan report written on wind power, eh?
