Thanks for the info. Actually, not new but stored in a box from an old QTH
so just thought I would make use of it for FD, 100W only

Note my caution that one or more caps are likely to fry with any mismatch at the filter -- that is, with a tuner on the antenna side. Likewise with any operator error, like working into the wrong antenna.

And as Dave noted, the relays go intermittent on receive. A dit may wet it, until you TX again.
