LF: 300W-TX-G0MRF (score: 1): Author: "dj9dw" <[email protected]>; Date: Tue, 6 Jan 2004 20:00:12 +0100; Hello group, as I can't get in contact with David, G0MRF, I want to spread out my problem here. The TX works fine except the outputtransformer T2. There is heavy ringing at abt 1 MHz. Now I figured,; /rsgb_lf_group-archives/html/rsgb_lf_group/2004-01/msg00106.html (8,256 bytes)

First: One reason for the ringing might be the transistors. Put a capacitor 2n7/ 3kV ceramic from drain to source at each PA-transistor.
