Hi Jim, I tried to find the "turnaround" time that is defined by
the ARRL tests as:
----------------------------------------------------------------
Transmit/Receive Turnaround Time
Test Description: The purpose of the Transmit/Receive turnaround
test is to measure the delay required to switch from transmit mode
to receive mode.
Notes:
1. T/R delay less than or equal to 35 ms is suitable for use on AMTOR.
2. No significant variation in CW mode.

Hi Jeff, sorry, I missed what you were after. I took a brief look
at the ARRL Test Results

and found:
ICOM IC-7800 17ms
ICOM IC-746pro 18ms
Yaesu MK-V 28ms
Kenwood TS870 18ms
Ten-Tec Orion 24.6ms
Ken, could you summarize what they're actually measuring? Time from Rx
audio stop to Tx RF emitted? or time from PTT asserted to RF coming out?
or what?
