Is your ham radio rig made of iron and steel ... the Alexanderson transmitter broadcasts are due to this very low broadcast frequency; your antenna is not long enough. If you’re in Europe ...

This chapter provides a brief overview of low‐frequency (LF) PNT systems but focuses on systems of the future. It focuses on radio ranging ... The chapter also describes signal reception and receiver ...

Early radio receivers worked on a principle called Tuned Radio frequency (TRF), patented in 1916. They weren’t very easy to use, requiring each stage to be tuned to the same frequency (until ...

Abstract: Having an accurate method to estimate and remove ionospheric effects is a major issue for low-frequency radio astronomy arrays ... those introduced by the satellite and those by the receiver ...

In this study, the special focus on low-frequency radio-frequency modulation offers a high degree of flexibility in choosing lattice points and regulating compound interaction. This approach ...

This GNSS RF Receiver IP is silicon-proven ... thanks to its ultra-low power design. Furthermore, the RF IP incorporates an integrated reference clock buffer to ensure a stable reference frequency, ...

AbstractAn exploding primordial black hole (PBH) may produce a single pulse of electromagnetic radiation detectable at the low-frequency end of the radio spectrum. Furthermore, a radio transient from ...
