Ham radio license study

Thanks @shortwave! That seems to be pretty much authoritative! It looks like I’ll have to retake the test to get back on air. From a bit of reading around today, it looks like there was a set of changes introduced in 2005, so my old qualification probably wouldn’t be recognized now.
 
I contacted the IRTS Secretary and he provided me with lots of useful info. I had heard of SDR, but I didn’t know there was an online installation on the web so it seems all you need to get into ham radio listening is your PC or mobile phone!

I will “tune in” online and see what is happening!

Many thanks for your support.
