>-- john, KE5FX John, I put in as K0 what I measured several times with the 10811 as 'gain' with -0.74 Hz/V. Is that not the right way? I tried to use several times also higher values. The result was not impressiv, did not give clear signs either. A factory reset I did not perform yet, but I am trying at the moment the proposed 0.2 or even a bit lower values. Tomorrow I will check the result, but up to now I do not have a good feeling. What about all these recovery parameter settings? I believe that they are not really counting for this problem.
