Tom, I believe you are on so something the way you have your audio wired up.
Thanks very much for detailed information and pictures of the way you do things at you QTH. I am not using such an elaborate sound system, just running the headphones direct into the rig. Speakers are SP 20 Icom and the other is a Ten Tec 307B. Using this method of plugging the headphones into the pnones jack, and using the speaker in put on the rig for output, there is definitely an audio problem when going from phones to speaker which requires and adjustment of the sidetone. Another way around this is to have an MFJ 784B tunable filter and use it for both both phones and speakers. This way the volume comtrol on the MFJ unit will equalize all audio and it will work the way I would like it to. Many thanks for your input!
