locked Echo mode on HF #modes #Echo

Greg Cook

Is it possible to use the Echo mode / or has anybody used the Echo mode to analyse HF propagation? By this I mean differentiate between long path and short path for instance using echo round trip times. Is the resolution sufficient to differentiate a delay of ~130ms for the long path from the short path? I realise everything is set up for eme distances rtt ~2.5s, but wonder if the resolution is sufficient for HF distances. Anybody using Echo for LDE's / MDE's?
