just changed my order with Ming from 330/46 to 660/46 100'
best and thanks again for this critical information
I am the fellow with the pictures of the yellow pails glued together with the 100 * 20 * 3 mm u=400 former Soviet block bars on same = this is going to be built Polydoroff Style

Hi Jerry! I have used both 100/44 and 660/46 Litz wire to wrap a 38
turnprimary winding on a 19” 125 mu ferrite bar, terminating in a 365
pfdvariable capacitor for tuning the MW band. In this context the
difference in Sunits as measured on my Palstar R30a was typically 7 vs
S+30 for most stations.There were many stations barely audible with the
100/44 coil that could bereally well heard using the 660/46 wrap. I
don’t know if this wouldtranslate into comparable results with a FSL
antenna set up but it sure makes adifference with monster ferrite bar
antennas that only have one ferrite rod,albeit one that is 19” long x
1” wide… From:ultralightdx@...

I am about to order some Litz wire from theUSA. Re Steve's recent Litz
wire comments on his FSL Loop and Gary' use of iton his FSL Loops, does
the much more expensive 660 / 46 Litz wire provide muchbetter
sensitivity than the 100 /44 wire listed in Gary DeBock's June
11writeup for the 7.5 inch Fixed Ferrite Loop? And if the 660 /46 Litz
Wire isbetter would the 7.5 Inch Loopstick still be required to have
122 Turns &1700 uh Inductance as was for the 100 /44 wire, or does this
Any comments would be much appreciated.
