About Me
I'm A65KJ / NH2OD, an amateur radio operator originally from Sri Lanka and currently operating from the UAE.
Getting Into Radio
My interest in radio started long before I became licensed. Like many people in the SDR generation, my entry point into the RF world was a cheap RTL-SDR dongle and a lot of curiosity.
What began as simple shortwave listening quickly turned into exploring everything I could receive or decode.
Experimenting Across the Spectrum
Over time that curiosity grew into experiments across the radio spectrum:
- 🛰️ Weather satellite reception
- ✈️ Aircraft and maritime signals
- 📡 Amateur radio satellites
- 📻 Digital modes and signal decoding
At different times I've experimented with everything from HF digital decoding and ADS-B aircraft tracking to receiving satellite imagery from orbit.
Operating Environment
These days I operate mostly from an apartment in the UAE, dealing with high urban noise floors and limited antenna space.
That constraint has become part of the challenge — figuring out what can still be received and decoded using creative antenna setups and practical hardware.
This Blog
This blog documents those experiments — what works, what fails, and the occasional strange signal hiding in the noise.
