Once connected, you should immediately squawk standby (unless you are in an aircarft where the transponder is linked to SB3, such as the PMDG 737NG, in which case it will be set to whatever your transponder is set to). Cheers Phil Thanks Phil. It just seems a bit out of sequence to connect, then squawk standby, rather than the reverse order, but I guess that's just how it is. Frank.
