[RFI] Got RFI ? - Some Good Solutions Material

[N6KI Dennis Vernacchia]

> Hi All,
>
>     I was in the process of making a group buy for our local radio club
> of some -31 Mix Ferrite clamp on beads
> that will fit tightly on RG-213 size coax and also be good for smaller 
> cables that I could
> thread thru several times for efficacy. ( Hole is approx 0.400" )
>
>     I discovered that Mouser Electronics now sells at least this one 
> particular -31 Mix Ferrite
> bead that works well for RFI problems per Jim Brown's recommendations 
> in the past
> on this reflector. ( These do well in place of 43 or 77 mix and I now 
> use this
> mix exclusively from 160 thru 6 mtr band to resolve RFI probs )
>
>     They are $2.70 in small quantity but drop to $1.70 for 100 pieces, 
> so get together with
> a few buddies or your local contest or DX club and snap up the discount !
>
> You can get to Mouser's order page by typing
>
> 0431167281 in Google search and it will be the first hit you get
>
> or go to www.mouser.com and enter part number  623-0431167281

> I found one anomaly with these and that is that if you do use them to 
> snap directly onto
> RG-213 type coax ( approx 0.400" Diameter) or coax with the same 
> diameter, the plastic shell that comes
> with the bead has a slightly* smaller *diameter than the hole in the 
> ferrite bead itself and will not allow
> you to clamp the bead onto the coax until you take a pair of diagonal 
> cutters and trim the
> plastic making the hole bigger. Just a nuisance for now as I have 
> alerted Mouser  and Fair-rite
> and hopefully they will use the correct plastic shell in the future.

>     Also, if you would like to buy 2.4" Round ( Donut ) type, ( 
> Fairite P/N *2631803802  )
> *and these are really great for really tough RFI problems, you can 
> order them from Dexter Magnetic Technologies   
>      I am not sure what their minimum order is but when I do my group 
> buys of 100 pieces
> I have gotten a piece cost down near $3, though I hear the price will 
> be rising sharply soon
> due to the price of one of the materials use in making the -31 MIX - ( 
> like going to $4.28 ea in 100 Qty ! )
