These are for variable-width crystal filters, similar to the K2 filters. 
  The variable-width filters will be available at some future date. 
Three of the five roofing filter locations on the main receiver -- and 
three on the sub-receiver -- are set up to accommodate these filters. 
All five roofing filter locations in each receiver can accept standard, 
fixed-width crystal filters.
