After sending a broadcast in V.6.2.4 PTT is hanging. After turn off transmitting manually at the IC-7300 knob the BUSY indicator in VARAC is still red, so any transmitting no longer possible until restart of the VARAC program.

In your 7300 settings > Connectors > USB Send/Keying which settings do you have "ON" ?
After changing the VARA HF Modem from v4.6.4 to v4.6.5 everything is fine!
