This pad should bring the audio level down about 23db between the rack and radio. The audio coming out the rack gear is usually much greater than the audio front end of your radio can handle. I would not suggest running any rack gear directly into the front of your radio without some type of audio pad or ibox. II Place cursor over image for a larger view. Here's a few pictures of my Behringer audio gear in a home brew rack. When using balance cable be sure it through out all your chain. These are the settings being used with my Yaesu FT, all equalizer setting in the radio are turned off and the radio band width is set to 3. Items highlighted in red are the setting I'm using.Įxample 80Hz is the best setting range to work with. The low end bass settings I have turned off only because I feel I have enough lows coming from the EX Mode OF set as off. You will need to adjust the parametric equalizer to your voice, microphone and radio every ones voice is different. Just another note: If you were using Unbalanced Cables coming into the Input of Channel 1 and going out of the Output of Channel 2, then you would use the opposite Balanced Cable to tie Channels 1 and 2 together. Doing this makes it an Unbalanced Connector. You can check with WZ5Q about doing the mod.
If your not able to do this mod yourself.

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.
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. If you want to see the details, click here.
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.
