Then one starts getting into trouble with using RX antennas with low gain, where the RX gain and pre usage IS appropriate. The FT1000MP *DID* have the de-emphasis you speak about. Over about a decade of usage, I wound up turning the de-emphasis off more than not, for use on RX antennas.
The Orion had an idea about that, having the RF gain numerical and remembered per band. Seems very logical. But it was a near universal confusion factor for new users. QWERTY may be an inferior keyboard arrangement to some, but try to change that, or get rid of the Microsoft "\". I had a proposal once which engaged most of your concept. The reaction to it was ten-to-one negative. Some things better left alone. 73, Guy.
