Hi Christoph, The image you uploaded from Dave's excellent presentation actually shows a circumference of 13.8m; close, but not quite the 15m you mentioned. I currently have an Azi-Loop in the

Hi All, I found an interesting site, there a archive of the defunct "ham radio" magazine. https://www.worldradiohistory.com/Archive-DX/Ham%20Radio/ I have been reading this article intensively for

Hello from Austria, I am an enthusiastic mediumwave BC-DXer and operate a small remote station outside Salzburg, which I have built up over the last 14 years. (https://remotedx.wordpress.com/ As I

Addendum: I am more inclined to trust IN3OTD's data because there isn't much opportunity to screw up a S21 measurement on a VNA. However, the Cedola et al's time domain measurement (OCVD) has more

I have a problem reconciling the measurements of Cedola et al and IN3OTD. I plotted IN3OTD's Fig. 1 data on a graph comparing 3 different types of *real* PIN diodes (below). ?IN3OTD's data are the

If anyone needs mounting nuts for ARCO and other brands of "padder" or "trimmer" capacitors, I have some that are surplus to my needs.? These are almost unobtainium.... VERY hard to find. They are

This subject was extensively covered and commented on a few months ago. I'd suggest you check the archives. Personally, I don't want to tune the loop every time I chase something else. They are

I have made several similar loops for BCB and NDB work. I wind the loop to about 330uH and use a BB112 Variactor to? resonate it, fed from a 0-10V Bias-Tee (indoors) . Very sharp / hi-Q and nothing

I like tuned loop antennas for AM BCB as well as for NDB chasing. I have a 45 inch on a side box 8 turn loop wound with #12 magnet wire and also use it as a crystal radio set. A good tuning capacitor

Yes, because it is not the genuine 2SC3357 from NEC/Unisonic, which is obsolete since a couple of years. It is a new part from EVVOSEMI, a fabless Hong-Kong based company, specialised in second

Just an update. DigiKey has 2SC3357 back in stock. They only have 1009, so it looks like they just got one reel in. They are listed as a "new" part, so I think the issue has been supply chain related

Lars, what do you mean with "3 m Loop"? Circumference of 3m or diameter of 3m? regards, Fred

I am curioues if any one tested THE lZ1aq Active Antenna Amplifier (model AAA-1C)? with 3m wire loop or even longer wire? 73 Lars sm4ive

Hi All, Very interesting thread. I looked at the circuit introduced. I felt nostalgia for the 2SC1815 and 2SA1015. They like staple foods for us from the 1980s until around 2010. The 2SA1015 was
