For those who hate to toss out perfectly good crystals, in hopes that perhaps they may someday find a use--- This table will allow you to determine whether or not the crystals in the drawer will make various pieces of gear operate on various frequencies in the radio spectrum. In many cases, a crystal from a VHF receiver may be able to make a UHF transceiver operate on a desired frequency. While there may be some tweaking involved, for those who can deal with "offbeat" frequencies (ham operators notably) the ability to recycle old crystals can save some cash-- and about six weeks of waiting!
