The FT-817 is based on a similar circuit architecture as Yaesu's FT-857 and FT-897, so it is a compromise transceiver and incorporates its features to its low price ($670.- at its 2001 release). [3] The upgraded FT-817(N)D was launched in 2004. The difference between the two models is the addition of 60 meter band coverage in 5 fixed channels ...
The 2-meter amateur radio band is a portion of the VHF radio spectrum that comprises frequencies stretching from 144 MHz to 148 MHz [1] in International Telecommunication Union region (ITU) Regions 2 (North and South America plus Hawaii) and 3 (Asia and Oceania) [2] [3] and from 144 MHz to 146 MHz in ITU Region 1 (Europe, Africa, and Russia).
Yaesu became an important presence in the U.S. amateur radio market with the introduction and improvement of its very popular FT-101 line of equipment in the 1970s.
