MFJ-550 Morse Key is a low priced key which can be used for practice, kept as a spare, or used in an environment where a more expensive key is not practical. For perfect balanced operation it is recommended that it should be screwed onto a wooden base.
The MFJ-261 connects directly to the transmitter through the PL-259 connector. No patch cable is used, this direct connection keeps losses to a minimum and reduces SWR. Cooling is accomplished by a finned aluminium air-cooled heatsink.
The YSK-857 Separation Kit consists of Front Panel mounting hardware and two 19.6 foot (6 m) interconnecting cables for the Front Panel. The kit allows the main body of the FT-857/D to be installed in the boot, or anywhere else out of the way.
