When one starts tinkering with the bias not only should they look at
current value but also at the IMD products while using a spectrum
analyzer. One can tweak the values of IMD down by having the correct
value of bias for each device. They will all be slightly different.
Just because the devices have the same device number and production lot
number does not mean the forward conductivity is the same nor will the
IMD be lowest at a given value of current.
My experience is that ~500 to ~600 ma per device is only a starting
point. Perhaps this is why Elecraft does not want the procedure made
available.
There's two kind of folks; Those that know what they are
doing........and those that think they know what they are doing. So
which group are you in?
