Try holding the tubes in front of your mouth and exhaling on them. The resulting fogging of the glass may make the original markings temporarily visible again. That's an old trick I learned years ago and it frequently works. 73, John, K9MM _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
