As a Amateur radio operator for the past 30 years I have found that one of the major sources of poor signal transmission, reception and generation of "Hash" while transmitting is usually a poor, loose or corroded antenna connection. Most aircraft antenna's are sealed in a plastic material and if water is introduced into the base, corrosion usually occurs. Water intrusion is generally through cracks or a missing cap on the antenna if it is of the type that is shortened by winding it around a fiberglass rod and encapsulated. The generated hash is pretty nasty in interfering with other pieces of electronic equipment. Richard [EMAIL PROTECTED]
