Hi. I've been flying again recently after having been busy for over a year. I've got the latest version of OR downloaded. My question relates to transponders - in the aircraft I'm flying I can transmit an ident code and it shows on the control screen. But no matter what I seem to do I cannot get any kind of acknowledgement for the codes I assign. I assign a code to a controlled contact and all I get is "----" next to the contact code in the flight strip, no matter what I set the code to - right,wrong,indifferent. I tried it with both "Visible to all" and "visible to [2017 and newer]" MP connect options. I've used Tikibar's 757, the Seattle Project 777, and other planes as well.
I thought it used to be different from that. Is it working right, busted, elsewise?
