From BTWR description of the 805:
"Some features can be customized using the optional programming software (free download) such as adding or removing channels or customizing the channel name, bandwidth, transmit power, or CTCSS/DCS codes. Support for up to 128 channels is provided, and receive-only channels can be added for any frequency in the 400-470 MHz range."
The 16 Channel thing I keep going back to is the "free" programming that used-radios.com offers on their stuff. They'll do 16 Ch. included. I have to remind myself that there are more available that I should be able to program in myself.
So, could I program channels for repeaters with tones and other channels for simplex, no repeater tones, with same TX/RX frequencies?
