First of all, thanks again for your poignant recommendations- of
course you are right! Since I am a few rungs down the totem pole from
the "digital" senior engineer who did the "designing" that is a tough
row to hoe. I will certainly try. For the meantime, I will take a
pocket full of ferrite beads and other such tricks to the lab and try
to plug the holes in the design dike with "band aids" as we yanks like
to call them. I still am lamenting the fact that engineering
graduates today have almost no understanding of analog - let alone RF.
