[UK-CONTEST] Echoing DVK

[nubsey]

Have an interesting problem here.
Using a Microham keyer (Mk1)and Win-test
When using Win-test to record a CQ the recorded message seems to have an echo or reverb type effect on it. Normal transmitted audio is OK  I cannot find any settings in the sound card driver that would have this effect. Varying TX Power output makes no difference. It sounds like we are operating from Canterbury Cathederal or a similar large echoing chamber!  Any ideas???
