VINTAGE HAM RADIO QSL CARDS 1925 6XAD - 6ZW from Avalon, CATALINA Island, CA Major Jordan Lawrence Mott, came to live in Avalon on Catalina Island. During the Great War, he had served his country as an officer in the Army Signal Corps. Just two years later, Mott constructed his own radio station and was granted an amateur operator's license with the callsign 6BX. During the following year, the callsign for the Mott station was changed to 6ZW. In the me...antime, Mott was also granted an experimental callsign, 6XAD, and this was issued around mid-year 1920. This experimental license granted Mott the privilege of making test transmissions with music & speech, on what was described as variable wavelengths. During the year 1924, Mott began work on the installation of upgraded new equipment for station 6XAD-6ZW which was installed in his home in Clarissa Street (Avenue), in Avalon. This equipment enabled the broadcast of speech & music, and he made a series of initial test broadcasts during the afternoons in the winter of 1924. During his 10 years of radio activity on the island, Mott was given very wide coverage of his radio events by the local newspaper, the Catalina Islander, and he issued many QSL cards. At least three QSL cards are known: a blank card printed with the callsign 6XAD, another similar card printed with two callsigns 6XAD & 6ZW. Old QSL Cards are often displayed using tacks and hang around on a Radio Shack wall for years. This can have a negativeeffect on the paper and the cards presentation. Moisture and humidity can also cause damage to the surface of the card.
