In this discussion two different ferrite mixes are mentioned: #31 and #61.

Over the years, professionally, we designed many Fair-Rite, cores into most of our electricity, gas and water meter and electricity load-management products and shipped millions of Fair-Rite products in our devices. Fair-Rite and Kreger are excellent suppliers, and I still have many of their development kits around here. Their products are excellent and very consistent Lynne Frye, of Kreger, is a very helpful contact person, that I have worked with over the years! Have a good day! 73, Charlie Cunningham, K4OTV -----Original Message----- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of Jim Brown Sent: Tuesday, August 05, 2014 3:00 PM To: topband@contesting.com Subject: Re: Topband: Ferrite Cores On 8/5/2014 11:36 AM, Mike Waters wrote: > FT-240-61 cores.

Other companies may make a "knock-off," but the REAL part is made by Fair-Rite. 73, Jim K9YC _________________ Topband Reflector Archives - http://www.contesting.com/_topband --- This email is free from viruses and malware because avast!
