Title: Ferrite material in output transfomer? Post by: SA2CLC on January 30, 2017, 07:58:17 AM Hello.
Planning on building a class e tx, have most of the parts on hand (IXDD414´s 11n90) but I dont have any 43 ferrite tubes. I do have a bunch of FB77-1024 ferrites, any idea if that would work? I plan to build a 100w carrier, 160m tx, single ended push-pull, using 2 11n90´s in each module. The power supply will be based on a 64vct 500w transformer. //Tommy, SA2CLC Title: Re: Ferrite material in output transfomer?

If you get stuck let me know... Stretchy. Title: Re: Ferrite material in output transfomer? Post by: steve_qix on January 30, 2017, 04:42:03 PM They are available from Mouser for sure. If you can't find the part number, I will try to dig it out. I've bought these from Mouser in the past, so I have the number somewhere.
Let me know. Sounds like a good project ! Regards, Steve Title: Re: Ferrite material in output transfomer? Post by: w8khk on January 30, 2017, 08:19:35 PM I just received an order from Mouser that included the cores used in the WA1QIX 400 watt Class E RF deck.
623-2643102002 is the Mouser part number for the #43 Round Cable Core; $1.51 each in quantity ten or more. I had them from Mouser in two days after placing the order. Title: Re: Ferrite material in output transfomer? Post by: SA2CLC on January 31, 2017, 02:02:28 AM Thanks.
I usually order from Elfa, but their price was $5.88 each plus shipping. I´ll check out Mouser, and try to come up with other components I´ll need in the future, to get over their free shipping limit. In the meantime, I might as well experiment with the #77 tubes and see if I can get it working. //Tommy, SA2CLC Title: Re: Ferrite material in output transfomer? Post by: KA6MOK on February 10, 2017, 06:30:59 PM I had been wondering about this, wanted to ask the experts if there are benifits to other mixes, maybe at different frequencies? Or is good ol' 43 pretty much optimal? AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
