I am a retired Embedded Software Engineer, specialising in Linux audio and memory systems for mobile phones and dongles but with a big part of my professional career being in automotive electronics and software.
My interest in amateur radio started in 2012 but I hadn’t got very far until 2015 when I retired and found the time to begin properly studying the radio world along with my other hobbies of Photography, Bird Watching, Astronomy and Car Restoration and Hillclimibing.
I don’t really like operating (there I said it!). My interests are mainly in the design of the electronics and software to make RF devices of all types.
At the moment I am designing hardware and software in the following areas:
- Accurate clocks (NTP, GPS etc)
- Accurate Frequency generation (DDS, PLLS, doublers etc.)
- Hydrogen Line radio astronomy (Very low noise pre-amps)
- RF Power metering
- Digitally controlled Attenutator
- 2.5GHz VNA
- Audio DSP processing
- 17KHz SAQ reception
- 60KHz Rugby Time signal Reception
- High Altitude Ballooning
- Low Cost TDR
- PCB Reflow Oven
- Maidenhead Locators
I am also interested in most things embedded and have written a lot of sensor drivers for Raspberry PI (all versions), Banana PI, Odriod, XMOS startkit, PICs, ESP8266 and Arduino. I play an active role in the Shropshire Linux Users Group (SLUG). and keep my own website active where I publish things I think may be of interest.
Over the past year I have branched out from embedded software and have begun writing software for FPGAs, CUDA GPUs, Windows PCs, Linux PCs and even the IBM Quantum experience.
I have no idea where it is all going, but at the moment I am just along for the ride!
