Hello Warren , K2ORS a écrit : I noted that from 02:30-03:00 when I put a carrier on that John's signal appeared upside down (mirror image) at 137.780-137.7806, probably due to an overload of the sound card causing intermodulation products due to the mixing of strong signals!Yes I saw it well , I will try to reproduce the phenomenon with two generators in order to know which was the level of your signals . I use the AGC of Spectrum Lab , and it is difficult to see the true level ! 73 Jean-Pierre f1afj |
