[RFI] List of ferrite sources and prices

Tue Sep 29 13:50:33 EDT 2020

Another suggestion is to purchase a full box of cores.I few years ago I purchased 65 pcs of the 2.4" cores from Arrow.  About 12 arrived cracked in shipping. Of course Arrow made good on the damaged cores.In a later purchase I ordered a full box of 100 pcs, again from Arrow, and they arrived in great condition. 73,Gary K9GS

I often make small purchases at Arrow, because they offer free overnight shipping for a $50 order for anything they have in stock, and they stock a lot of the Fair-Rite parts we are likely to need.73, Jim K9YCOn 9/28/2020 9:15 PM, Gary Johnson wrote:> Here’s a price and stock survey on ferrite toroids and clamp-ons for ham RFI applications. I post this occasionally. Some of the entries were updated a couple months ago, others are older. Stock status fluctuates... Anyway, this will give you a general comparison of prices and plenty of alternate sources to check. And you’ll quickly see why Palomar Engineers is the last place you want to go when buying ferrite.> > Gary NA6O> ————————————-> > Showing only suppliers with websites that list inventory and allow online ordering.
