Using a 6600m 2.331and just getting on 6m I noticed some strange behavior. While trying to run 17m FT8/CW on Slice A and listing on 6m for FT8 on Slice B, using both the front panel and smart SDR I get strange mix that appears to be AM signals. I also can see this behavior when running 20m and 17m and running 6m and 80m again both front panel and smartSDR. when I switch to 40m it disappears as well as 15. I have not conducted a matrix test of all combinations of bands, however I did notice that if the behavior is present 6m & 18m and I open a third slice in smart SDR on 15m it disappears and I get good AM free reception. (second pic) Also there are some occasional CW signals it is like the front end is wide open or something. I have tried bypassing the ATU, no difference am running v2.1.33, on Ant1 for all of the band slices. While I am very close to WSB-AM 750Khz 50kw perhaps 10miles the AM signal is not WSB-AM. Even my old IC-735 does not have issues with AM mixing like this situation.
