What's in this update

enchanced ID and CTCSS encode operation and new featu​re additions When a port needs to ID, the other port(s) no longer just "hang" until the IDing port(s) finishes, although there will be no courtesy tone.

Normal hangtime will now work.

Added new ID function to allow a port programmed as half-duplex to still ID.

This is useful for IDing links.

The normal ID rules (speech/no speech IDs, Initial and Pending ID Timers) apply.

If a port is programmed to repeat, this setting it ignored.

Added radio memory recall capability when using Kenwood TM-V7A or TM-G707 for a remote base radio.

Up to 255 memories may be recalled (these are the memories stored in the radio, not in the RC210 memory) Fixed bug in TimeOut routine, where time out message didn't speak correctly.

Now if a user times out, the controller will speak "Repeater Time Out" and then drop that port's transmitter until user unkeys.

CTCSS Encode timeout may now​ be selected to start on closure of COS or upon completion of Courtesy Tone.

This allows for much more flexible timing, such as accurately emulating "chicken burst".

CTCSS may now be selected to be generated during IDs
