I am dealing with a system (half duplex), which sends a pulse through the network. I've had this question quite a bit, but never been able to word it right. Hope this is understandable. 

This "ping pong" issue only occurs after the transmitter is unkeyed.  There is no way to fix this in hardware ( don't need to complicate it by going into technical details on how the link is setup)

RXONDELAY WORKS, but it is sort of pointless because now the beginning of everybody's transmission gets cut off, and is physically does not need to be. 

We are really looking for 

TX UNKEYS ------>   Disable RX ------ > Wait 1/4 second ------> Enable RX

NOT 
RXONDELAY:
USER KEYS --->  DISABLE RX ------>  WAIT 1/4 Second -----> ENABLE RX

Is there any way to perform the function in mind? ( in either usbradio, or simpleusb). Has anybody here thought about this before?

Thank You,
