Hi Hugh I think the rule of thumb (or at least the one I use) is that the lowest turn should be at least half the coil diamter from the screen base (which if too close will exhibit the properties of
Hi Hugh,mmm that is quite a lot. Thinking of the copper lined tuning huts Decca and Orfordness I guess the keg should be grounded. ?? Alan G3NYK -- Original Message -- From: "LineOne" <dhchurch@lineo
Hi Paul I came across Gerald in the 90s when I was part of a 2-way radio company, my oppo knew Gerald quite well from the FCS. He was a nice guy. One of my local LFers worked for him as well. I have
Hope that helps a bit Alan G3NYK I enjoy reading all of the posts, but I'm having problems with a few that the font is too small and my "old codger" eyes are having a real challenge to decipher. Woul
Hi JB yes as someone said, there are those that will post in "dangerous" HTML and the reflector passes those, like others, straight through. (I know......that is a contentious statement :-)) ) I thin

Trim grass They are renaming it "Lawnmower Watch" It saddens me that a university falls for that one. The Radio Astronomy Group has a number of members with sensitive recording geomagnetometers. Thes
Trim grass Hi Luis that is another case (microwaved pies) where you might have thought technical minds would have realised what it was sooner. I remember two cases where I was called in to telephone

Hi Hugh they can create horrendous RFI if you are not careful. The ones used for TV distibution "may" be better......the good ones are notched at the amateur bands and being for digital levels dont u
That is interesting Markus. I did several years ago discus the possibility of ICM at the time of a CME impact with Vaino OH2LX (an ICM expert)......on the grounds of increased electron density due to
