Title: Where to buy ferrites without going broke?? Post by: K8DI on February 25, 2020, 10:19:16 AM Hello --
As I consider many D/E amps/transmitters for experimenting, I keep looking at the BOM cost. The FETs are cheap, compared to the magnetics and MLCC capacitors. I added up a particular circuit the other day -- $20 in silicon, $64 in ferrite, $120 in ATC capacitors. This seems kind of backwards to me, maybe there are better sources than the standard parts houses (digikey/nouser/newark, and kitsandparts/amidon/amazon for ferrite). Who's got the line on lower cost passive parts?? Ed Title: Re: Where to buy ferrites without going broke?? Post by: KD6VXI on February 25, 2020, 08:22:07 PM KF7L Metalworks.
Googlrnwill get the site for you. He's a small shop, really good prices in small and large qty and I'd rather support an entrepreneur than a conglomerate. --Shane KD6VXI Title: Re: Where to buy ferrites without going broke?? Post by: vk3alk on February 25, 2020, 10:16:26 PM Hi Ed....
Things do add up I must admit.... I tend to buy in small amounts building up on stock so I always have parts available....particularly if there is free delivery involved.... Take Rods TX...appox $ only... PCB $ 4- 2 IXDDs $14- 4 FETS $24- CREE C3M0280090D 2 T106-2 $ 6- 4 Dipped Silver mica caps $20- Poly Caps bought millions from ebay LPF 7 pole 4 T106-2 $ 12- 3 Russian Glass things $ 8- Hmmm about $100- ..... never thought about it really ....... However its a powerful Transmitter ... probably in the 300-400 Watt mark..... Still quite cheap though.... Wayne Title: Re: Where to buy ferrites without going broke??

Wayne, yeah, $100 is an experiment I can do, which is what I was referring to in my other thread about Rods circuit. Some other common circuits on here are easily twice that for just the deck passives, which as an experiment I have more trouble justifying. I’m going to build Rods design, I think.

Typo from the oh one keyboard. I purchase all my ferrite from him. --Shane KD6VXI Title: Re: Where to buy ferrites without going broke?? Post by: K6IC on March 02, 2020, 11:59:46 PM Hi Shane, was not trying to be too Snarky. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
