I have a Rockland analog filter I purchased at a Ham radio fest many years
ago. If someone would like to purchase it, make an offer.
As I do not have any packaging I will take it to a package/shipping store.
This cost would be added to your offer. If I get multiple
offers the highest will be considered.
E-mail me directly at: n0ssy@...........
