The world of radio communications has changed a great deal since I last dabbled in it.
The heavily modified, rack-mounted Racal RA1772s that I played with have been superseded many times over.
A few days ago I was surfing a particularly nerdy corner of t’Internet when an aircraft blipped on to my radar (literally).
The application I was using gave me a significant amount of information about the aircraft, even that it was communicating on 1435Hz.
If only I knew a radio amateur who had more up-to-date knowledge of receiving hardware than I, I thought. I would then be able to ask him what piece of kit would be good for receiving 1435Hz (and other frequencies of interest).
Hmm. Now where do you suppose I might find such an individual?
