My plans today were to get out to my Winter Survival shelter and operate in FYBO and the RaDAR event. But snow and a very low windchill changed my mind on the outdoor adventure, but with about 45 minutes in the RaDAR event left I decided to saddle up my PRC-104 with Chameleon whip and give 15 meters go. With luck I was able to work a few RaDAR stations. Even in -15c (-21c with blowing snow) a warming smile was brought upon my face.

Thanks to those who pulled me out and gave me the opportunity to play late in the game.

I could not feel my fingers when I got back into the house but it was a great experience none the less.

The Raspberry Pi2 was delivered very quickly – thank you CPC! However, owing to a bit of silliness on my part I didn’t get it running until today. I’d assumed – always a dangerous thing – that the Pi2 used an SD card for its storage, like the Pi. Oh no it doesn’t! It uses a micro SD card. I didn’t discover this until I went to plug the SD card in!

Ah well. A quick Amazon order later and a micro SD card and an adapter was on the way. Those arrived here this morning, so I quickly prepared the micro SD card.

I had a bit of fun getting decent video on my rather old monitor in the shack and was starting to think I wasn’t going to find something better than VGA! However, a setting of hdmi_group=2 and hdmi_mode=16 gave me a reasonable compromise between getting a decent amount on the screen and being able to read it without green and yellow flashing in the background.!

The first bit of software I installed was the Gpredict satellite prediction program. It’s nice to have the map running in the shack. That went well and only seemed to be taking a very small percentage of CPU.

Then I installed RTLSDR and tested it, without any problems. I installed DUMP1090 – the ADS-B decoder as well as the Piaware software which uploads the ADS-B spots to Flightaware. Those programs run quite happily at the same time as Gpredict and use around 7% of CPU.

I fired up the Epiphany web browser and went to Twitter – again, the CPU was quite happy.

This looks very useful. I think I’d better order it a case!

Earlier last week I posted about how my solar banner seemed to stop updating and not showing the current day's condition. I emailed Paul N0NBH about the issue and he responded very fast asking for more information. We exchanged several emails and he was very helpful and wanted to get to the bottom of the problem that I was having with his solar banner. Paul explained to me that Chrome and Safari browsers seem to have issues with his banner. He went on to explain that on his site there are some other links one being  Marv (W4ZD) that may work better for me. For you Mac Safari users (like me) he also provided a great link to an article that deal with clearing Safari's cache using some simple short cuts. It would seem with Paul's solar banner when using Safari or Chrome the cache has to be cleared and the your page reloaded for the banner to update. On my desktop that runs Win7 I have not had this issue.

      THIS WEEK'S NEWSCAST

      Script

      Audio

From my bank statement I see my 40m Pixie kit from China, that has shipped, cost a little over £7. This includes all parts including crystal and PCB. At this price it would be hard to buy the individual parts. I very much want to build this as it will be the first amateur radio construction here in a very long time.   It is sufficiently simple and low cost that I should manage it, even if I am a little clumsy still with the soldering iron.

 No doubt Andrew G6ALB (3km) will help with a first test.

Many times we hear that closing old and polluting power stations is putting us at risk of power blackouts. Check the electricity capacity yourself.

In the left hand corner you can also check for France.
