Today, April 23rd 2017. I carried out a similar experiment to yesterday but with WSPRlite G33CWI reduced in power by 3dB compared the WSPRlite G31CWI. 57 simultaneous S/N … read more

Radio amateurs making measurement tend to just believe any figures they see. This leads to various wildly incorrect interpretations of the data. Antenna testing in particular is prone to all sorts of … read more

MethodA Chameleon P-Loop and an Alexloop were erected in an open flat area. The area was clear of any obstructions. The antennas were 30 metres apart and orientated in the same way (approx. 064 mag). … read more

The Alex Loop is a popular commercial small transmitting loop antenna.Measurements here are simply an aide-memoire for my own experiments. They should be used with caution.Loop conductor Datalink … read more
