Première fois en 34 ans d'adhésion à l'ONU (un.org) que 🇪🇪 l'Estonie demande une réunion d'urgence du Conseil de sécurité.

Morning, all,

reprehensible double-tap attack by #IDF killing journalists and medics.

As reported by a Palestinian doctor on #BBCWorldService, the strike targeted an upper storey of a hospital building, in which mobile reception was still possible, allowing press reports to be filed.

Who is going to hold Netanyahu to account for his government's genocidal acts in Palestine. Action is required now...

Environmental NASA satellite publishes EW detection in the clear.

Explanation: EM spectrum used for soil moisture is adjacent spectrum used for drones.

Log periodic antennas are wide-band directional devices, suitable for signal hunting or simply wide-band communication. Their gain isn’t impressive, this one is rated to about 6dBi, that’s the price you pay for bandwidth.

The commercially made are really expensive, literally an order of magnitude above this eBay unit which was about 60$. But I suspect they have a similar PCB inside anyway 😂🤷🏼‍♂️

So how well does this unit perform? My #nanovna_v2 cuts off at 4GHz but starting at about 700MHz, it surely delivers a reasonable match below SWR 1:2 (620MHz for SWR 1:3)

I’ll have to bring it to the lab at work to test the upper frequency limit 🙂 For now, let’s go signal hunting! 😎
