If you use a wideband loop antenna, a cheap Distill AM Bandstop Filter reduces SDR overload from local medium wave signals. Read more
Today, we will talk about a couple of 3D printed solutions to improve mounting and using the AAA-1C amplifier box. Read more
Everything went well with my commercial LZ1AQ unboxing. This active antenna amplifier appears well made and extensively documented. The kit was complete and well packaged. Read more
If you want a sense of how well magnetic antennas can perform, check out the VA6OK remote wideband loop for yourself. It’s one click away.
My initial wideband loop testing shows reasonable MW and Lower HF performance, but I need to address shielding and impedance matching to prevent the CAT7 from acting as an antenna. Read more
You can use an LTSpice FFT to check expected performance from an amplifier, and compare simulated results to the data sheet specifications. Read more
