    All set for a field day, the aim is to test a home-brewed vertical coil (have an EFHW as backup) with the QMX and zbitx v1, test-driving a Gigaparts POTA20 mast, and the portable ESP32 powered HAM Clock I’ve been working on with the local club. In case, all goes well, might attempt a POTA. #fieldoperations #qrp #qmx #zbitx #amateurradio #hamradio #pota #esp

    In a strange turn of events my 13 year #Kindle was decided to walk out on me. Any recommendations for a DIY/ #esp32 / #pico powered alternatives that are less restrictive? I’m not inclined to go towards a Kobo with #koreader. My candidates are: - Touch version of Open Book: https://www.crowdsupply.com/oddly-specific-objects/open-book-touch - Dual screen reader: https://www.crowdsupply.com/diptyx/diptyx-e-reader/updates/custom-cases-and-production-progress - PineNote: https://pine64.org/devices/p...

    I guess a win for open-source and open-hardware in a way, my #FrameworkLaptop laptop had issues with recognising USB ports and there was a major boot issue with my operating system. #fedoralinux fixes the boot issue &amp;#39;automagically&amp;#39;, Linux has really progressed! I followed the guide to reset the motherboard on Framework&amp;#39;s site, and now the USB ports work perfectly fine.

    Fun start to a group build we are doing at our radio club BARC (https://www.barc.in/), this is based on the work already done by SP3KON using an #esp32 CYD. Has some useful things to such as band conditions, APRS, HAM Alerts, POTA Spots, etc. Needs a bit more work to get it useful in the field, which is where I operate. #amateurradio #aprs #homebrew

    I&amp;#39;d say #LabourDay well spent, finally got around to powering the #zBitx from a powerbank and some bug fixes on the HAM Clock using an #esp32 CYD to get it up and running. A few more fixes and I&amp;#39;m all set for the next field day in better conditions :-). #amateurradio #ham #qrp
