Re: Trial to control CW power (and reduce harmonics as a result) by unbalancing the 2nd mixer #ubitx

It seems the slightest leakage from "open" unbalances the mixer -and an Arduino output doesn't deliver that cleanly. Physically switching the key, direct from the panel socket or by relay, may be the only way to get clean CW by this method.
