[R-390] Mechanical filter postmortem

Mon, 08 Apr 2002 11:53:21 -0600

I have repaired several Mechanical filters in Yaesu gear, but they open a
lot easier than the Collins filters do... In the Yaesu filters, it is
usually migration and decay of the 'foam' padding that causes an increase
in loss through the filters... Yes I have had to resolder a couple of the
pick-up coil leads also.. 73 de Jordan...
