FT-817 CW Filter Installation

I received my long awaited YF-122C 455KHz Collins Mechanical CW filter today. It was a snap to install, but there are a couple of things to look out for. Here's the photos and story. Click on any of the photos to see the full size version.

1. Removing the top cover is simple - first take off the shoulder strap brackets (4 screws) and then remove the 5 screws in the top cover and it pops right off - don't undo the two screws nearest the speaker grille, those hold the speaker in place on the underside of the top cover. Be sure not to damage the speaker wires or connector. The wire from the speaker is pretty short but there's just enough room to get to the connector to undo it if you tilt the top cover up at the rear.

2. The filter goes in the space at the front of the board.
