Re: Bit of practical today
Did the practical course explain why a choke balun is a good idea if you are feeding a balanced antenna with unbalancd feeder??
I thought not. 
I really must get my ass in gear and sort out the foundation exam.

Re: Bit of practical today
no just that a balun was a choke and would help with tvi and rf coming back down the braid, i did ask why the diferent baluns, ie, 4:1, 1:1 ect but they said they didnt want to confuse me as they were teachin me to pass the foundation and to just take that on board first,, lol

Re: Bit of practical today
You also get a different call sign, I mean, a new call AND 50 watts how can you not take it? There may be more but there the ones I know anyway, you would learn new stuff to!
