One thing I did with the Signalink on my 746Pro was insert an 18K resistor
in series with the TX audio right at the radio connector. This allowed me
to raise the audio level from the SignaLink and improved my transmit S/N
noticeably.

As an engineer who designed RF systems in a place far away and long ago,
the cost of switching 100 watts of RF electronically as opposed to a fast
relay device is MUCH higher.
Most Amateurs simply would not want to pay the price of fast all-electronic
switching when they
don't need it and it
Bottom line: Cost versus ROI. Too expensive for the few who would see the
need or advantage and - more importantly - be willing to spend the extra
