Yaesu FT-817 Operating Manual 2015-02-27

The Yaesu FT-817 is one of the smallest MF/HF/VHF/UHF multimode general-coverage amateur radio transceivers. The set is built by the Japanese Vertex Standard Corporation and is sold under the Yaesu brand.[1][2] With internal battery pack, on board keyer, its all mode/all band capability and flexible antenna, the set is particularly well suited for portable use. The FT-817 is based on the same main circuit board 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 the 60 meter band coverage, other display lighting options, modifications in the RF stage, the included FNB-85 battery-pack and NC-72B charger.

The FT-817 is one of the most famous QRP transceivers[4][5] and there is a variety of modifications[6][7] ranging from frequency extensions to internal antenna tuners.[8]
