If you look at the metadata and filenames, you’ll see the timeline of a world in transition: from the screeching sounds of dial-up modems to the birth of the "phablet" . To give you a better feel for the atmosphere at the station, check out this video of us in action at the studio . Sitting at that table with Meirion and Romina , we tackled the "future" every week.

And pretty cheap ones! 2022 I've got some Heltec V1 (Stockholm) Is good to mention that this technology uses ISM which basically is that the states provide a license-free b...
