[Elecraft] K2 SSB crystal filter set lacks calibration value

[Mark Petrovic]

Hi.

My K2 SSB option inventory correctly has the part number E850006 qty. 7
4.9MHz crystal filters, but the envelope containing the filters has no
calibration value recorded on the outside.  Is there an easy way to
determine what this value should be?

Thanks.
