[Repeater-Builder] Re: E.F Johnson Repeaters
Travis, Thank you foer the updated material on the Johnson repeater. I the photos of the CR1010 it shows the correct controller for this model. The one I have has a Johnson controller board, but it appears to of an older series. It does not have the keypad, digital display, or the power switches. But it does have a controler board, Call Guard board,and PL tone board. Thanks again.

From the thread Eric suggested you contact ICM and send them the whole elements. That was exactly what I did and the cost was $168.65 shipped. Turn around time was less than 10 days. Call ICM. They were very helpful. Tony N2MFT

[Repeater-Builder] Re: E.F. Johnson Repeaters
James I'm not sure when you contacted ICM about re rocking your TCXO but I had no problem with them in July 2008. I sent them 2 TCXO's. They were rocked and compensated and returned in less than 2 weeks. These were for the CR1010. Catalog # Description 41534 JOHNSON#521-3(518-2)TX(440-474)CR101 41533 JOHNSON#521-2(518-2)RX(440-474)CR101 37006 ICM TO INSTALL,TEMP/COMP TEST Maybe you should call ICM back. They are still listed in the current catalog. Tony 2c. Re: E.F.

I have a CR 1010 repeater that I have crystaled for the ham band. The first place I called was ICM and they did not want to work on the TCXOs at all. I then called Bomar Crystal and they would not work on the TCXO either however they had the specs for the crystals and would cut them for my frequency. I haven't had time to tune the unit but I did install them in the TCXOs and it wasn't too hard to do. I do hope that it is stable when all is said and done. The CR 1000 would be a good machine for ham use, I would put the performance up there with the big M and GE equipment of that same time period. thanks James N0QZV --- In Repeater-Builder@yahoogroups.com, D. n5...@... wrote: Hello to the group. i am in need of some information on E.F.

I also have a third PA without any markings on it other than this A033A053A 21532 I would like to have anything that would pertain to modifying there to the UHF Ham Band. Manuals on the original configuration from E.F. Johnson, to details from someone who has made this mod. I will furnish Photos if this would help. Thanks, Danny N5DRG
