QSL SV1YY (1965)

Amateur radio QSL card send by SV1YY to VE3BLU in Ontario, Canada, confirming a 7 MHz CW QSO in May 1965.

This is an unlicensed operation under a self-assigned call sign, quite common in Greece before 1967. Dimitrios Psimorifos (now a silent key) was eventually licensed around 1980 as SV1NY.
