It appears the Japan amateur radio manufacturer, Tokyo Hy-Power, has filed for bankruptcy and ceased trading.
Their main Japanese corporate website is now offline.
I was very surprised to find this handy talkie, the Tokyo Hy-Power XT-751 HF handheld transceiver, at the Dayton Hamvention. This radio will cover from 40 meters to 6 meters in both SSB and CW. It will also have an internal ATU. It is only a concept radio at this point.
Tokyo Hy-Power hopes to have this radio in production mid 2014.
