Graham, the page you referenced is of the "MnZn" chemistry. These have high permeability and also have the property of being low-electric-resistance. As such these types of ferrites work best under

. . . Is there an accurate and prooven method for breaking a ferrite bar so, that you get 2 truly identical parts? . . . > Using a sharp triangular file, score a ~0.5 mm deep groove all the way

I cant think of a perfect method.... however one way that has shown promise was to score the rods with a diamond scribe around the circumference, and use an industrial tile-shear to finish the break.

Hi all As I understand 100mm ferrite bars are the better choice for a FSA than the 200mm bars I own. Is there an accurate and prooven method for breaking a ferrite bar so, that you get 2 truly

Sorry for the bad-looking layout... I don't know what happened to my log.

Hi Steve, I only put that page up in case of interest because it came up via a search and showed equivalents. So is initial permeability THE determining characteristic I wonder ? Maybe the nature of

Hi all, I was a bit tired last night, but I nevertheless managed a short listening session before falling asleep. 11 NEW ONES were heard this time, including a NEW DXCC : Serbia (# 15). 380.0

Hi Graham, The initial permeability of the Chinese-manufactured A2 Nickel/Zinc 100 mm x 10 mm ferrite rods you are using, purchased from the UK company Rapid Online, is approximately 125, which

Wow Patrick, 102 NDB's and 14 DXCC Countries is a pretty good result for 3 days of Ultralight DXing! You certainly seem to be having a lot of fun using your new radio, and welcome to the 100

Hi Raph. The rod I used is linked in my writing All I know about it is A2/ NiZn, and it works well at MW. http://www.rapidonline.com/1/1/4790-ferrite-rod.html Cheers ....... Graham.

Hi Graham! Which ferrite rods did you order from Cosmo, and what was the unit price? I could not tell which would be comparable to a NiZn rod with permiability of 125 mu (e.g., optimizable for MW

Hi Steve, Just came across this. http://www.cosmoferrites.com/product/matcomp.html Kevin e-mailed yesterday, and I forwarded the .pdf file for the ferrite rods I am using, and upon which my writing

Hi all, I uploaded another video of my Eton G8 being used barefoot for FMDX under mild tropo conditons, here in Blackpool,

Hi all, No static yesterday evening, but only fair conditions... no real DX, nor rare NDBs. I nevertheless looked for scandinavian beacons, in vain. Anyway, even using 'Top-Class' receivers with

Not great LF conditions, but did add two more. Trying a Kevin's Tecsun PL-210, much wider filter but not as much DSP junk heard, I think I like it. 270 logged. Steve NE Oregon Tecsun PL-210, 40-rod

Oops, forgot the radio used was the PL-200. And that makes 25 X-Band stations. Paul S. in CT

Yes, solid wire is much worse Q-wise than Litz. However, if you look at that best inductor, Ben used #31 solid wire of the same turns and coil length. The spacing is nearly 2 parts space to 1 part

Got busy today, so heres last nites happy recap. The West opened up a lot, and I logged WQLR Kalamazoo, MI as several station mentions on 1660 kHz. WWRU and WBCN could only partially null, their

Hello Nick, Thanks for the interesting story, and warning :-) It's certainly true that fanatical receiving antennas can boost the reception capability of Ultralight radios into the "big

Hi all - two new ones, including TNK from VK8 - the last missing Australian state. Date GMT Freq ID Km QTH 20110315 1850 272
