Worked today JX5O. Conditions on HF were terrible. Deep QSB and a lot’s of noise. A Big Gun’s CW pile-up from EU don’t gave me any chance to call them. But, finally I got JX5O in SSB. Below is sample of JX5O’s SSB signal on 20m. (5 or 3 minutes RS-55 and about 20 minutes…
The Yaesu Twin concept is a high end concept for the serious ham who do not accept any compromise even when remote controlling his station. It was initially developed for controlling OH8X Radio Arcala which is one of the most impressive stations in the World. The concept is simple at the same time as it…
