Hi all; This time I need a 100 kc crystal for a Hammarlund frequency standard type FS-135-C crystal calibrator. I would prefer one that has the same pins as a type FT-243, but I will take whatever I can get. The original is a Bliley KV3 that won't come closer than 98.5 kc. Please quote total cost to ship to zip 93065. Thank you. Ed K6UUZ
