[TenTec] Omni V narrow (model 218) 9 MHz crystal ladder filter option.

[Bwana Bob]

Sometimes the crystals in the filter just go bad with age.

Recently, I've noticed adding this narrow filter mutes the receive signal almost completely when any filter selection (2.4, 1.8, .50 or .25) is selected  It did not do this in the past.  The jumper is in the correct (pins 2&3) location for this filter, as well.
