Valletta- NOT amateur radio
VLF converter
Many people want to have a dabble at VLF reception and want to know what is down there but most receivers don’t go that low. Many years ago I designed and built this up converter so I could take a listen. Receiving commercial stations such as time signals and MSK signals is easy . Reception of AMATEUR VLF signals is highly unlikely to work as this usually needs very narrow bandwidth and precise frequency setting. Details of this upconverter and how to improve it are on my website.

Marsaxlokk, Malta - NOT amateur radio
Today we visited the fishing “village” of Marsaxlokk in SW Malta famous for its colourful fishing boats. It was not what I would call a village!
Over the horizon optical tests
It’s many years since I last did these tests and I remember being amazed that on a cloudless night I could clearly receive my 481THz beacon way over the horizon without any signal visible. Had my stroke not got in the way, I am sure much much further would have been possible even with my simple QRP system. The receiver I used is attached. It was also in RadCom. It is also on my main webpages.
Typical on Malta - NOT amateur radio
It’s probably fair to say the countryside on Malta 🇲🇹 is barren. In the hot summer months it looks dry and arid. This cactus 🌵 is typical of Malta.
Original 10m WISPY TX
One of my Facebook memories today was of the original breadboard version of my WISPY WSPR TX on 10m. The date was 2012. I think the PA originally had a 2N3866 which I later replaced with several 2N3904s in parallel which was far less expensive.
2m beam?
What looked like an 8 over 8 yagi for 2m was spotted this morning on a rooftop somewhere in Malta 🇲🇹. It was on an extendable mast. I guess Italy 🇮🇹 and North Africa are in range. I am not sure what town it was.
