How about things like true wide range transmitter output matching (like 30 - 600 ohms instead of the only 50 ohms like most rigs now).
Improved transmitter noise and spurious emissions (i.e. as good as, or even better than, the best tube type units - solid-state transmitters are virtually all much worse in this respect).
Decent receiver intermod and overload specifications without having to resort to attenuators (i.e. the KW up the block doesn't take out the whole band due to "front end overload").
Frequency standard easy to calibrate to WWV (prefer use of internal WWV receiver). By this I mean the oscillator that sets the basis for all frequencies including transmtting and receiving.
All mode operation including AM, CW, SSB, FM, computer protocols, etc.
AGC that works well on all modes.
Transceive or "split" operation that is not a "compromise" with shared circuitry. Ability to work "cross band" between any amateur band that is covered by the unit (i.e. transmit on 160 meters, receive on 2 meters, etc.).
Straight forward operation (don't have to know all the "tricks" of making the rig actually work).
Making the rig "impossible" to overdrive (this would eliminate "spurious" emissions caused by "flat topping").
Full AM capabilites without having to "play games" with power level, audio level, etc.
Step type FM deviation control to allow the deviation to be accurately set depending on the frequency used. Better yet, an internal control that will limit the maximum deviation depending on the frequency while allowing less to be used.
1 Hz tuning rate, but extremely fast when needed.
Optional MARS and CAP frequency expansion for the transmitter while preventing other use outside of the amateur bands.
General coverage receiver capabilities.
Internal automatic identifier (burst type, microseconds in duration) that would have to be programmed with the amateur call sign before the unit can be operated.
Excellent sounding transmit and receive audio without exceeding FCC technical specifications.
Transmit with loads from "short" to complete "open" without any damage to the equipment (continuous transmit specification).
Ease in service (can be field serviced by the average amateur - this one will be hard!).
Reasonably priced.
