Often, it isn't the filter at all, but the fit between the filter pins and
the on-board pin receptacles. Check each corner to see whether the pin
seems loose in the socket. If so, remove the filter and, flatten the pin
very slightly to obtain a tighter fit. Be careful and don't overdo it. If
squeezed too much, the pin won't go down into the socket and will require
filing off excess width.

I recently had problems with my 2.4 SSB filter. At times it worked fine,
other times the RX sens was terrible and other times it was dead.
I found by wiggling the crystals it would return momentarily to normal. I
found several crystals with terrible solder connections. I re soldered the
entire board (the pins that plug into the radio were bad too) and it now
works fine. A couple of the crystal pins would not reflow and I had to
remove the solder and put a small wire around the crystal pin and connect to
the foil to get them to resolder.
Do not know if this is your problem but something to look at.

Does anyone have any insight into problems (and solutions) that would cause
failure in a Ten Tec model 282 (or any other similar model) crystal filter?
When the unit is plugged into its slot (on a Corsair) we get no response.
Our next step is to test it on a network analyzer but I felt it would be
worthwhile to also get inputs from people on the reflector.
