I notice when AO-7 is out there at 4000km I can notice the delay in cw from my monitor to the 8000km round trip to and from AO-7. Kind of shades of AO-40 (sobsob) when the delay was really noticable, and when we listened to ourselves (ssb) we had to turn down the rx volume a little as no to sound like a babbling fool. 73 Bob W7LRD
