ICOM debuts SHF transceiver
Icom showed a mockup of this transceiver, capable of operation at up to 10 GHz at Dayton. Apparently, it got a good enough response that they’re going to start manufacturing it. How much would you pay for a rig like this?
$4 Logic Analyzer Based on Raspberry Pi Pico
In a recent EE Journal, Steven Leibson writes:
Here’s a truly inspired project. Dr. Agustín Gimenez Bernad, a Senior Developer in ServiZurich S.A. in Spain, has created one of the most brilliant hacks I’ve seen yet. He’s built a 24-bit logic analyzer that samples at 100 Msamples/sec and stores 32K samples from nothing more than a $4 Raspberry Pi Pico board and some clever code. There’s a lot to learn from this project, which is posted with some very fine documentation on GitHub, but if you just need a $4 logic analyzer, there’s still a lot to be admired.
For four bucks, why wouldn’t you want to have a logic analyzer in your shack, especially if you do any microcontroller projects at all.
