[Laser] cheap filters

[clhough]

Andy have some 12 inch to 3/4 inch glass filters for 650 Nm that are
available for $5 postpaid. Filters are not perfect in that they were cut out
of a large piece of filter glass material and not perfect square, but work
very well in our laser communicator that Kerry N6IZW and I have built.
Filters seem to be about 5 Nm wide about 650 Nm. Best 73 Chuck WB6IGP
