Post Subject: I was taling about purely mechanical noises...Posted by Romy the Cat on: 3/20/2011

Actually my SU-2 has multiple shields for different reasons – they are different type of shields and each of them work most effectively under different conditions and help for different type external noise. However, it is not really important. What you are saying has to do with shielding. It is important point but it was absolutely not what I meant. I was not taking about shielding but about the way how chassis react to stay field radiated from transmitters and chokes. If you have an average or beyond average chassis thickness and you put on one of the panel of this chassis 5-6 powerful transformer and chokes then you will have a lot of resonances coming from the fact that stay fields will use the chassis as core. It is very had to comfort this type of resonances. It has nothing to do with shielding but with purely mechanical noises that chassis will pickup from magnetics.
