Good FT8 reception today on 12m. Mostly with WSJT-X Improved V3.0, but also partly with MSHV 2.76.4 and standard WSJT-X 2.7. The antenna is a TF2D, Diamond WD330S, and the receiver is the FTdx10.

Am I the only Windows and Linux user who sees huge differences in the number of FT8 decodes in Linux (LMDE) compared to Windows 11? Same PC, same set, same settings, and in a full waterfall, Linux decodes between 7 and 10 per pass, Windows between 35 and over 40...

Time to waste some time receiving HFDL messages. It's always fun to keep up a bit.
Using MultiPSK for it with the FTdx10.

Connected a BME280 sensor to the #Meshcore transceiver Heltec V4.
SDA goes to GPIO 17
SCL goes to GPIO 18
Vcc = 3.3v
Needs some calibration 😄

24-hour FT8 reception on 80 meters. I don't think it's bad at all; the antenna used is a Diamond WD330S T2FD antenna. Ultimately, it uses no more than 2 x 10.5 meters of wire in a folded dipole, resulting in a span of less than 10 meters with a dummy load terminating resistor.

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.
