As is the way nowadays we can take technology for granted. In fact this post is being typed out whilst travelling up the m74. The point is that this afternoon I had a lightning quick qso with Julian, G4ILO with my new my new hand held. The verbal part was accompanied with what is normal for aprs. A conversation between the two rigs to introduce themselves and to say they are in range.
It wasn't until I started to try and explain all the goings on did I realise that this quite a big deal. Its very easy to buy a black box on the internet and use it. Quiet another thing to understand what is going on inside. It reminds me how little I really know about a hobby that just keeps moving.
