RigPi transmit unkey delay problem


I have recently set up an MFJ-1234 with RigPi to control an Icom IC-706MKIIG transceiver. It all works well except that there is a delay of several seconds after releasing the PTT of the radio going from transmit back to receive. It does transmit properly however.
I’ve tried different settings in the setup menu but cannot find a way to correct the problem. I am not using the CW keyer just the PTT. Can anyone provide a suggestion for a solution.

Thanks. VE7CQH
