Small untuned loop for receiving – simple model with transformer gave a simple model for analysing a loop and and Towards understanding the YouLoop-2T at MF/lowHF applied that to the YouLoop-2T. Above is the Airspy Youloup-2T. Try to put the two turns thing out of your mind, it is misleading, panders to some common misunderstanding, … Continue reading YouLoop-2T and the self resonance bogey at MF/lowHF
Small untuned loop for receiving – simple model with transformer gave a simple model for analysing a loop. If you haven’t already read it, you should. It provides a step towards understanding the YouLoop-2T at frequencies where is is a small loop (perimeter<λ/10). Above is the Airspy Youloup-2T. Try to put the two turns thing … Continue reading Towards understanding the YouLoop-2T at MF/lowHF
I have written several articles on untuned loops for receiving, as have others. A diversity of opinions abounds over several aspects, but opinions don’t often translate to sound theory. This article analyses a simple untuned / unmatched loop in the context of a linear receive system. An example simple loop for discussion Let’s consider a … Continue reading Small untuned loop for receiving – it’s not rocket science
Three recent articles developed an explanation of the YouLoop-2T at MF/lowHF: Small untuned loop for receiving – simple model with transformer ; A transmission line 1:4 impedance transformer ; and Towards understanding the YouLoop-2T at MF/lowHF . The first and third articles explained the concept of signal/noise degradation (SND) statistic, and gave graphs of the … Continue reading SND implications of variations on the untuned small loop at MF/lowHF
