    Very funny DXCLUSTER spot comment by F1GTU regarding TI9A FT8 operation. Maybe they were watching Super Bowl? 😃😃

    Last Sunday we activated DL0ESA club station from ESA’s ESOC in Darmstadt via QO100. Worked 99 stations from Brazil to China and from Iceland to South Africa. Portable from the parking lot.

    Looks like the Abracon VCTCXO board for use is currently being manufactured. Got this pic from the fabrication house in 🇨🇳 to confirm component orientations.

    Actually around 1.6 ticks per second, or 16 ticks in a 10s period. TX goes for minutes, so I assume some files being sent instead of digital voice.

    Someone testing a 7kHz wide digital mode on -100 around .630.5. More than double than the recommended bandwidth. Mode unknown, but about 1s frames audible ticks.

    Received some panelized test PCB’s for the Pluto SDR TCXO breakout board. Just to check how easy they can be broken apart. Fabricating a small batch in a professional fabricating house will be the next step....

    Designed a small 7x18mm size VCTCXO breakout board for the Abracon ASVTX series for ADALM Pluto SDR modification. Currently checking with a fab house. Ideal for those guys that do not dare to solder this 2x1.6mm tiny thing.

    Some VSAT parts for the trash bin at friends company. Could any of those be useful for repurposing it? Or creating a SAT pirate station, perhaps? :-)

    Terrible signal, very distorted, too wide, too much power with overdriven amplifier....featuring IT9EZO via (and joking that a DL ham was earlier complaining to him about "too high power"). Some people just don't get it....time for LEILA :-)
