Hi Mike,
There are at least two reasons why this option can be interesting:
1) remote site where you have to pay attention to the power consumption (solar panel..)
2) if you have problems with a radio can NOT even handle other devices attached to the com ports and use it, if necessary, with a second radio
Do you think it possible to establish the link between the two remoterig without having to turn on the radio or change the settings?
I noticed that if on the remote site the power supply of the ts 480 is off, but I try to turn the radio on, the connection between the two remoterig is successful and I can use the com ports....
