Wide frequency coverage, outstanding receiver performance, and the convenience of optional remote-head operation make the FT-857D the experts choice for high-performance mobile operation.Utilizing an up-conversion architecture for HF with a first IF of 68.33 MHz, the FT-857 features a double-conversion superheterodyne system (triple conversion on FM), with the 2nd IF at 10.7 MHz.
Extensive bandpass filtering in the front end, along with careful device selection and gain distribution, yield a receiver system ready for the strong-signal challenges of todays crowded bands. Enjoy the excitement of public safety monitoring, along with weather broadcasts, AM and FM broadcasts, aviation communications, as well as the action on the Ham bands.

For example, for a channel center frequency of 5332 kHz, you tune a traditional transceiver to 5330.5 kHz. Set up an FT-817ND857D897D to the 5332 channel, and tune your FT-1000MP to 5330.5 kHz. Now transmit from the 817ND857D897D; you will find that you are precisely on frequency as you monitor on the other transceiver.
