sure - you interpreted me too literally!? I have tried placing a xtal filter there, with various forms of matching, and an LC filter - to improve spurious in the SSB path.? its the CW path on 40m (and 80m) that is corrupted by these modifications.? and removing C22 impacts CW on these lower bands - in at least 2 v4's (N3SB is the other).?
How is it related to this question on why Jan's 40m output is down a bit?? maybe I was presumptuous that he was measuring output power on CW?? possibly he was - as for most of our rigs we tend to measure output on CW.? however of course the ubitx is different in this regard.?
all okay.? for now I am content with my ubitx doing well on all bands CW, and the lower bands up to 17m on SSB (with low enough spurious).?
