Dah Dah Dit Dit Dit... Dit Dit Dit Dah Dah
When in short trousers and listening to my first hams I remember being baffled by someone making a comment then saying somewhat flatly ‘H I’.

This being derived from .... .. diddyditdit ditdit being the morse equivalent for laughter.

Of course these days when we want to emphasise that the comment was humorous we bung a smiley on the end.

Welcome to the quirky Tony Hancock world of ham radio: “Friends all over the world! Just none round here.”

Sometimes it took so long to work out what was being said that it may as well just have been sent in English!

I was thinking of Z codes when I read this, at the RAF HF Receiver station (1980s) we would usually use Q codes in teleprinter conversations useful to get an instruction or question across quickly especially if the signal was deteriorating. We did use Z codes but the only one I remember was ZAL (I'm closing down now) at the end of conversations.

QRP, according to a t-shirt a few years back at Hamvention in Dayton, is 1500 - 1 Watt ( Legal us limit )
Real QRP guys think more about max to 5 Watt.
