HackRF One SDR transceiver

Elector has a special offer on these SDR transceivers that go from 1MHz to 6GHz!! I do not know what power they put out but I guess mW only. They sell for 249 Euros with a free book.

Storing intermittent grid energy - NOT amateur radio

This is the "holy grail" of renewable energy. These days solar and wind energy are cost effective, but they are not always there when you need them. Crack storage and renewables will be the way to go. There just may be an answer. At the moment this is an MIT project.

Steve G1KQH may have to close his eyes!

Is 5G a myth? - NOT amateur radio

 Is 5G all a myth? A new book seems to suggest this. This was on the Elector site today.

Elector free of 3 months

The electronic edition (plus 1 paper copy) will be available free for a few months. The offer runs out shortly.  See https://www.elektormagazine.com/pages/newsletter . I cannot see the catch. Maybe they assume if you like the free ones you will sign up when the free ones end?

If my memory serves me correctly, this started as a Dutch mag that went international in the late 1960s or early 1970s?

Elector valve radio kit

Not having built valve radios (far too young at 62, HI HI!) my eyes were drawn to the latest offer from Elector magazine for a complete valve radio kit built into a neat wooden case. See https://www.elektor.com/Uploads/2011/6/Valve-Radio-Kit.pdf. This uses a low voltage valve (6J1) in a regenerative design with a transistor audio amp. At around £50 with shipping it is not cheap, but it is a complete kit. For the offer see https://www.elektor.com/extra/valve-radio.1843103.lynkx .

Technology Page

The Tech the Future page has an interesting mix of articles on new technology and is worth a read from time to time. See http://www.techthefuture.com/

Shoe power source (from Elector Newsletter)

A novel way of generating a small amount of power using a piezo-electric generator within a pair of shoes is shown in the latest Elector Newsletter.
