Tonight, Dwingeloo radio telescope will be featured in the musical piece "Le noir de l'étoile," which will be performed in Freiburg. We will transmit the ticking of pulsar B0329+54 live to the concert hall, where six percussionists will take over the pulsar's rhythm.
Vanavond speelt de radiotelescoop mee in het muziekstuk "Le noir de l'étoile", dat in Freiburg wordt uitgevoerd. Wij sturen live het tikken van pulsar B0329+54 door naar de concertzaal, waar zes percussionisten het ritme van de pulsar overnemen. www.rtvdrenthe.nl/nieuws/17957...
Bijzonder moment voor Radiotelescoop Dwingeloo: 'Tweehonderd mensen luisteren naar het ritme van het restant van een ontplofte ster'
De historische radiotelescoop speelt vandaag een bijzondere rol in een internationaal muziekproject.

The better half has been lounging on the couch for about two days now, watching nothing but crime shows on the BBC. Given the number of murders in the series, you'd think there would be about 16,384 murder cases a day across the Channel. Where else do they get their inspiration?

Last year I was asked to pull an old radio out of a loft near here.
Turned out to be a HRO from WW2. It had a rusted away lethal power supply and a wooden speaker full of wood worm. I spent the morning building a PSU/Speaker for it from junk. Switched it on and it works after a fashion.

If you are a satellite operator and have not filed an objection against AST SpaceMobile's request to use 70cm, it's time to get busy. There's still time.
Don't just sit waiting for other organisations to do it on your behalf.

It continued in this mode until 0512. UT.
I looked in signal wiki to see if I could determine what it was but couldn't find it exactly.

Another holiday. Every time a struggle... We have been on the road in France for 4 days now. Tonight we are at a beautiful spot on the Loire in Sainte-Gemmes-sur-Loire. It is now 32C, tonight something like 20C. So it will be nice here near the river.

Been working on the "Smurf" last few weekends as we had to do some small modifications. Decided to do that after we had been touring France oktober last year. Shelves in the kitchen base are now extendable because we always had to get on our knees if we wanted something that was a bit further back
