Note: Only some Icom radios support controlling the split function from the serial port. Those

that do include the IC-725, IC-726, IC-765, IC-781, and IC-970. The IC-R71, IC-R72, IC-271,

IC-275, IC-375A, IC-475, IC-735, IC-471, IC-575, IC-751, IC-751A, IC-761, IC-1271, IC-1275,

IC-R7000, IC-R7100, and IC-R9000 do not support turning split on and off from their CI-V

interfaces. If you attempt to turn split mode on for a radio that doesn't support it, the controller

will send the command and respond as if it worked, but the radio will not change. If you want to

control split mode remotely, you can wire one of the controller's output lines to the split button on

the radio. Then you will be able to "push" the split button by turning the output line on and off.

Digit 9:

"p 9": Bump up 500 Hz. If you are in transceive mode, you may get an error if the new

frequency would be disallowed by the transmit edges. Voice response is "Up 500".

Digit 0:

"p 0": Selects virtual VFO B. Has no effect if you are already using virtual VFO B.

Restores the receive frequency, transmit frequency offset and mode to whatever they were

when you last used virtual VFO B. VFO B is called a "virtual VFO" because the controller

keeps track of it separately from virtual VFO A so it will work as you would expect, but

both will usually use VFO A on the radio. In other words, if you look at the radio, it will

probably show VFO A even when you select virtual VFO B.

"p 0 x" or "p 0 xx": Writes the contents of the current virtual VFO into virtual memory

"xx". This includes the receive frequency, transmit frequency offset and mode. Since the

memories are virtual, that is they are stored in the controller's memory rather than in the

radio, all 100 memories will work regardless of whether your HF radio has built-in

memories or not. Voice response is "Write xx".
