Yaesu FTDX-3000
Na Dayton Hamvention 2012, firma Yaesu zaprezentowała swój najnowszy Transceiver FTDX-3000. Urządzenie obejmujące pasma KF + 50 MHz o mocy 100W, wykorzystuje szereg sprawdzonych rozwiązań zastosowanych w FTDX-5000, ponadto wyposażone zostało w 3,5 calowy wyświetlacz LCD (480×272 pixele), który wyświetla wszystkie istotne informacje o pracy, statusie i nastawach urządzenia, a także S-metr i wbudowany analizator widma. Transceiver zapowiada się bardzo interesująco, niestety jego cena nie jest jeszcze znana. Urządzenie jest nieco mniejsze od FT-950, nie ma wbudowanego drugiego odbiornika, ani zasilacza – można tylko domniemywać iż docelowy klient dla tego sprzętu to dotychczasowi użytkownicy właśnie 950-tki, czyli powinno to być dużo poniżej 10 KPLN.
