[Boatanchors] Int'l Crystal Closing their doors in May

[Jim Larsen]

I was Just thinking about ICM closing. What might happen?

Everyone is talking about the ICM database.  Here is an action question?
Who is going to do something about it?  Maybe ICM would be willing to
release all the data into the public domain sort of like Wayne Green did
with 73 Magazine. Folks scanned all the 73 issues.  Maybe someone would be
willing to scan the ICM database.

The ICM database would be a nice resource for hams and for and all crystal
manufacturers.  And the wide distribution would help the data to not
disappear.

73, Jim
