The main Service Manual is 25Mb! In the "Audio Techniques Menu" section, specific instructions for attaining 'good' ESSB audio including adjustment techniques, alignment improvements as well as tips for proper audio system interconnection. Also, the "Alignment" manual contains the "how-to-do" instructions including the required test equipment to properly align the radio. This data is a must if you plan on making any changes.
ESSB AUDIO CHAIN PDF
Each PDF contains the schematics, board layout and parts-list of all modules. The capabilities of this radio seem, at first, overwhelming.īut once you spend some time looking at the operational manuals, browsing through the schematics and playing with the knobs, you see the best of all worlds is built into this radio. The techniques described here are directly applicable to the FT, however the recommendations are applicable to any modern HF transceiver. The information here centers the use of external audio equipment and, secondarily, use of the internal parametric EQ to attain improved Tx ESSB audio. Too bad that the techniques involved a lot of ckt part changes which put off a lot of FT owners.

A word about the FT a great radio which never made a big splash on the ESSB world until the mods I designed and implemented made it a real 'sweet' player [60hz to 3. This radio contains the best of the "old" analog radios and the "new" digital world of electronics called Digital Signal Processing. This was a 'hybrid' since it was Yaesu's attempt to marry analog and digital techniques. I can vouch for that since I had mine 18 years! Next was FTMP which was released in the mid 90s. The original, the FT, was released in the s. The FT is the 3rd generation in the lineage of the high-end "FT" line of radios.
