Remoting the control head, which is very cool, should not be the determining
factor. What does the control head do? Makes changes to the radio.
I have hooked up the 480 via IP with a computer interface that gives me the
exact same information. Worked great.
The control head is just a user interface, if you will, just like a
computer. The transmitting and receiving are still taking place where ever
the rest of the radio is located.

When one starts to split the transceiver (one part at the remote site
another part at the control point) as is being proposed with the TS-480
control heads how does that impact the rules that all transmitters,
receivers and antennas must be located within the 500 foot circle?
I realize that we're only talking "control heads" here but in the larger
sense what constitutes the "transceiver?"
If one could place a truly high dynamic range, wideband A/D converter at the
antenna and transport the entire 1.8 to 30 MHz spectrum to DSP running at
the control point where would the receiver be? Similarly if one had a high
power D/A converter feeding a power amplifier at the antenna and generated
the digital bit stream to feed it at the control point where would the
transmitter be?
The latency issues will become less ... or latency in home station radios
will become greater with greater use of DSP techniques ... so that latency
in remote operation will be less of a "disadvantage." Most individuals do
not even notice the 500 millisecond or so "round trip" latency in digital
cell phones ... similar delays will become commonplace in the ham rigs of he
future.
