RIGHT!!!

I've got all my bits and pieces and got the transmitter up and running!!

Very happy - its all still on a breadboard but I'll sort that out later.

At the moment, with a 6 inch antenna - it will transmit all of about 12 inches

but I'm still a happy camper.

But of course I have a bunch of questions now that I can't really find answers to on the web.

My Transformer is supposed to be 1000 Ohms to 8 Ohms - but when I measure the primary and the secondary I get about 400 and 4 (approx those figures) - Im guessing that is because I'm measuring simple resistance, while they are quoting Impedance - Is that right?

And I've been looking around at a bunch of different transformers and they seem to be described differently:

Min is 1kOhm to 8 Ohms

But some are described as 5w to 8 Ohms - what's that all about? I can't find a simple explanation

I know Ohms Law and P=VI etc, and I can do the algebra (Maths is not my weak point - electronics is!!) Does the 5w relate to any combination of V and I that will equal 5w, and can I then use any particular combination of V and I (lets just say 10v and 0.5A for the sake of the discussion) to calculate a resistance??

Doesn't really make a lot of sense....for one -I'd be calculating Resistance - not Impedence.

Anyone want to take pity of a poor Newby.....
