Starting to go mad because I'm trapped in the house … every time I walk out the door half the Atlantic drops on my head ..
So earlier this week I dropped £200 on a HackRF 1 SDR radio. This is a Swan Vestas matchbox sized Software Defined Radio as pictured below with the mouse to give it some scale. (Sorry it's upside down but the aerial is on one side and the computer the other.) It tunes from 1 MHz through 6 GHz, an enormous chunk of the human used radio spectrum. There was a time when anything above 1 GHz was known as
'witchcraft frequencies' in the trade, now they've got it into a matchbox !!!
Been testing it out today on the PC, will demodulate pretty much everything from Morse upwards. Also, you can actually build your own digital signal processing projects with downloadable free software (for Linux only as yet.) It transmits as well … but I'll need to research that one because you're getting into grey waters legally on anything outside the Amateur Bands.
It's pretty though, you must admit with all those spectral waterfall displays (all done in free downloadable software.)
SHIT I need to get out more …
