Info_Au - That very well could be the case, though Hams broadcast on more than just high frequency bands... I read somewhere that it could refer to using a meat tin as a natural sound amplifier... another theory says that in early telegraphy ham meant a poor operator... the first wireless ops were old landline telegraphers, and might have been complaining about the amateur 'Hams" clogging up the airwaves... so it is a mystery...

Stuart - Thanks again for the encouragement and tips. I will remember that.
