CQ means "Calling any station" in the earlt days of radio, morse code was THE only means...and it was much easier to build your own equipment, for just doing morse code. voise is another story. so to save keying the whole phrase "Calling any station" a shorts word structure was developed. letters instaead of words and phrases. its so common now that any ham who hears them knows what they are, even though with todays technoligy, computers can do the code better faster and easier than ever.
Atilla,
actually, other than the sight of the antenna, a properly run, tuned station will cause no interference with tv's and other electronics. even running up to the radio's maximum capability of 200 watts, i don't disturb anyone. and the antenna is in a good spot. its really not in anyons way, view or anything. of course most of the time we run as low power as possible, enough to make the contact. allot of guys like to run "qrp" very low power, typically under 5 watts. their signal can be heard across the globe, under the right ionsphereic conditions.
