John, I suggest that you send the holders, with the old crystals, to International Crystal or to any competent crystal house. Simply instruct ICM to change the TX and RX from the existing frequencies to the desired new frequencies. It'll cost you about $100 for the pair, but you'll wind up with crystals that are guaranteed to work on the new channels.

Sent: Thursday, January 24, 2008 5:28 PM To: [email protected] Subject: [Repeater-Builder] EF Johnson CR1010 Crystal Replacement I have a CR1010 repeater that needs to have new crystals installed to change the frequency from 451.200 to 451.250 on the TX and 456.200 to 456.250 on the Rx. I tried to get crystals from EF Johnson and they said they no longer support this repeater. I then tried to get crystals from International Crystal and they said there were two types of holders new and old. They said that if I had the new type I would be unable to get crystals for them or they would never work. It just so happens this repeater has the new crystals so does anybody know where I can get a set of old crystal holders so I can change the freq. on this repeater? Also does anybody have any other good ideas on how I can proceed with this unit. Thanks
