It is not actually a carrier but LO leakage from the commutator ic FST3253 and
there is no adjustment you can make to null it on this implementation.
I use sdr1k with the 100w PA and I have measured this leakage to be -20dbm @
160m (70db below 100w)and 0dbm @ 10 m (50 db below 100w but only 30

hi .i am having a problem with my flex 1000 i have a carrier on ssb and i
