I hope that this post marks my return to regular blogging for London Shortwave. I know I had said this in one of my previous posts over a year ago, but this time I am more optimistic. Many things have happened since I last blogged: several stations have sadly gone off air, I have traveled to a few far flung destinations where I managed to do some radio monitoring, and I have experimented with further miniaturising my portable spectrum capture set-ups.

Something different! This may be the first video footage of the Abuja Lugbe transmitting station on Twitter (shot by yours truly). This station is used to beam @voiceofnigeria's shortwave DRM signal to the world! More info: https://t.co/Rku4rGKlIr 📡 @SWLingDotCom @realmarkfahey pic.twitter.com/iS8DLetBQK

One of the things I would like to write about first is my PocketCHIP SDR recording solution. I was originally planning to share a step-by-step set-up guide last year, only to discover that PocketCHIP's maker, NextThingCo, had gone out of business and stopped selling the units. However, it turns out that there are still some for sale, so this should still be relevant to the SDR community.

I was also lucky enough to receive one of the first AirSpy HF Discovery SDR production units, which I look forward to evaluating and writing about on this blog. I hope you stay tuned and visit again for more updates.

P.S. I hope my blogging efficiency will improve with the help of this neat little device.

Greece and Turkey's shortwave broadcasts recorded one early July evening

Some traditional Greek and Turkish music for your listening pleasure.

Both recordings were extracted from a spectrum capture of the 31 meter band made outdoors in London, UK on July 2, 2019. The recording equipment comprised of GPDWin, AirSpy HF+, Bonito GI300 and Bonito MA305 portable active antenna.
