>From time to time we have had discussions here about the problem with PSK (and other modes) when a strong stations appears to grab the waterfall and wipe out all the other stations within a 2-3 Khz range. Because of this phenomenon, when I purchased a new rig, I looked for one that could have AGC totally off (when needed) and one that can employ narrow DSP filtering. I must say that I have not really solved this issue . I can see a marginal difference with AGC turned off but strong signals still essentially desensitize other stations in the waterfall. The DSP features do better and I can get rid of the phenomena by turning to a narrow filter. However this does not help if the offending station is with 300 - 500 Hz ( a lot when dealing with narrow digital modes).
Does anyone have any advice on how to once and for all solve this issue? My rig is a TS2000 Andy K3UK
