He also tells me the Yaesu personnel dropped a hint that the long awaited FT817 replacement would be launched at Dayton next year. Personally, I think Yaesu badly misjudged the market and should have launched this when the peak of cycle 24 was still building. They are 3-4 years too late! What a sales opportunity wasted. Now, with waning solar activity that could last for 30-40 years, who will buy it? They had a ready market for half a million units worldwide. It had better have some really strong features if it is to sell in 2016 onwards.
