Losing ICM was like a knife to the heart. As a owner of several Vintage repeaters, Hamtronics, Kendecom, and HI-Pro This was bad news. But I found Bomar crystal, and they have made several orders for my Kendecom repeaters. They have the Formulas for the build, but I would suggest you check the numbers too. I have not ordered anything for Hamtronics or Hi-Pro as yet but I do have the Formulas If they don't. Owning old Equipment is getting harder, I just found out Jerry Vot of Hamtronics Passed away a year ago and it doesn't look like anyone took over.
I need to reprogram Eproms for the Hamtronics COR-5 controller and am looking for a vendor.
