For the last couple of months, I’ve not done much in the way of traditional radio, largely down to the fact that I’ve been really busy at work. I’ve had lots to do and I’ve spent a month working away from home either on training courses or in meetings preparing for a very large project. […]

An updated internal and external ADS-B comparison
It’s been well over a year since I moved my external ADS-B receiver to the top of my Alimast and it’s been performing very well, regularly sitting in the top five of the UK receivers according to the FlightAware statistics page and in the top ten world wide on the PlaneFinder sharers list. A good location […]
Installing a good quality TCXO into my Kenwood TS-590SG
Over the years as I’ve operated QRSS and WSPR, I’ve noticed that my original TS-590S and then the replacement TS-590SG have always been slightly off frequency and suffering from a little drift. This frequency inaccuracy was barely 30Hz which seems minuscule but when monitoring a section of the band which is only 200Hz wide, the […]

Building a JYE Tech Cap Meter 060 Kit
One of the new local Foundation licence holders recently did the Intermediate course and exam and as part of her practical assessment, she built a capacitance meter which I’m sure helped her pass the course. Well done, Caroline! I fancied doing the same as it’s a handy piece of test gear that I’ve never owned. […]
Time for a new aerial, I’ve replaced my doublet with an OCFD
A detailed look at three different methods of operating the low power WSPR mode
There seems to have been an upsurge in people operating WSPR recently. Barely a day goes by (sometimes barely an hour) without someone posting a map of where their signals have been received on Twitter. When I first started experimenting with WSPR and QRSS some years ago, I did exactly the same. I’m quite sure […]

Returning to data modes after an enforced break
My shack computer is an Apple iMac. For a few years, I’ve operated a lot of data modes and been very successful in data contests. I’ve always enjoyed data modes and in 2012 I operated GO6NHU to celebrate the London 2012 Olympics exclusively using data. Back in 2015, Apple released a new operating system called El Capitan and […]
