The Yaesu FT-857 is one of the smallest MF/HF/VHF/UHF multimode general-coverage amateur radio transceivers. [46] The set is built by the Japanese Vertex Standard Corporation and is sold under the Yaesu brand. [47] The FT-857 is developed on the FT-897 and MARK-V FT-1000MP transceivers. [46]
The Yaesu VX series is a line of two sequences of compact amateur radio handheld transceivers produced by Yaesu. There is a line of ultra-compact lower-power dual-band (2 m and 70 cm) transceivers that started with the VX-1R and was later updated with the VX-2R and VX-3R.
Yaesu is a Japanese brand of amateur radio equipment, founded as Yaesu Musen Co., Ltd. (八重洲無線株式会社, Yaesu Musen Kabushiki-gaisha) in 1959 by a Japanese radio amateur Sako Hasegawa (call sign JA1MP [1]) in Yaesu, Japan, a district of Tokyo.
In the ND model Yaesu (Vertex) replaced the FETs with RD07MVS1 FET's but the problem may still exist. Be aware that the RF stage may remain sensitive to damage. [8] The internal battery should be removed if the radio is to be stored for an extended period. In the non-ND model, a failing battery can cause the finals to oscillate which destroys ...
The FT-1000MP is an amateur radio ("ham") transceiver series, built by Yaesu.It is an "all-mode" set, operating in the high frequency (HF) frequency range. The "MP" suffix in the name was an homage to Sako Hasegawa, the late founder of the company whose callsign was JA1MP, and who heavily influenced the design and feature set built into this radio.
The set is equipped with an early design synthesizer and local oscillator design and was prone to drift, inaccuracy and phase noise. Yaesu introduced circuit modifications in the later production series to improve on the issue, but was not able to completely fix the problem as the underlying concept remained unchanged.
A Yaesu FT-891 Radio Tuned to the 10 Meter Band. The Yaesu FT-891 is a HF and 6 meters all mode mobile amateur radio transceiver. The FT-891 was first announced to the public by Yaesu at the 2016 Dayton Hamvention. [1] The radio has 100 watts output on CW, SSB, and FM modulations and 25 watts of output in AM. [2]
GMSK using a sound card - this method uses a computer sound card to generate GMSK modulation and de-modulation. The primary software for this method is developed by Jonathan Naylor. An example of a repeater system using this technique is the addition of D-STAR to the Yaesu DR-1X repeater by attaching the UDRC and a Raspberry Pi computer. [28]
