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 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 (USA model only), other display lighting options, modifications in the RF stage, the included FNB-85 battery-pack and NC-72B charger.
The FT-817 is a QRP transceiver.[4]
The FT-817(N)D is no longer in production, and has been replaced by the FT-818, which improves on the previous model with an increase of RF output from 5 to 6 Watts, higher capacity battery and the inclusion of a TCXO for better frequency stability.[5] In December 2022 Yaesu announced they were also discontinuing production of the FT-818.
