So much stupid having it adjust both RX and TX together with the one control. If you have it so your clarifier alters your TX as well as RX then when you adjust your clarifier to receive them better your TX frequency changes. So they then end up adjusting their clarifier so you sound better to them but that then changes their TX frequency so again you're adjusting your clarifier on the next over so they sound right which also changes your TX frequency, they adjust so you sound right which then alters their TX frequency, rinse and repeat until one of you hits the end stop of the clarifier control.
