Dear Kumar,

it is a sad history.. it is a long time= that here in EU (but I guess also elsewhere) we are dealing with incredibl= e low prices of chinese products... sometime I read on e-bay or similar pla= tforms goods offered to a price, included freight, lower of the shipping pr= ice alone (from Italy).
Some items are good or at least good enough for = the purpose others lack for some feature..
It is an hard world! :-D
B= y the way concerning ferrites and iron dust cores properties will suggest t= o download a software called "mini ring core calculator" just goo= gle these four words and you get plenty of possible download.
The softwa= re provide calculation of inductance for cores made from Amidon, TDK and Fe= rrox.
The other longer way is to download catalogues or data sheets from= the producers or from the web pages of sellers like digikey, mouser etc.
P.S. please do not use ferrite cores for the base loading coil of you= r (ex) top band vertical!! wind a large huge coil on suitable cores like pv= c draining pipes.
Don't worry with 14m vertical and some top load th= e coil is not so big :-) - after all this will a training for 137 kHz windi= ng, and if you will follow Stefan... for larger and larger loading coils fo= r VLF!

We all hope to hear good news from you soon
