We’ve featured a lot of radio receivers over the years, and this certainly isn’t the only one that’s a bit unconventional. Posted in FPGA , Radio Hacks Tagged 20m , fpga , HF , radio , receiver ...

Series4100 HF receivers are designed to support future capabilities, such as HF wideband. According to Shephard Defence Insight, the R&S M3SR Series4100 radio family also supports IP-based split-site ...

Designed to help HF radios and receivers that struggle with front-end overload from AM broadcast interference, compatible with Xiegu radios X6100, X5105, G90, G106 and SDR receivers.

Also to be discussed are Boeing 787 HF receiver issues, the European VHF Data Link Mode 2 (VDL Mode 2) infrastructure and global aircraft tracking. Ahead of the conference, ...

It is relatively easy to design a receiver for the HF spectrum (3-30 MHz) with sufficiently low noise figure that the system noise floor is set by atmospheric noise, not receiver noise. The ...

The HF whip may drive an untuned low-noise amplifier. This paper shows how to calculate the sensitivity of such a receiver, and compares the theoretical values with practical measurements.

About 20,000 of the 55,000-plus R-390 HF receivers made came from Collins. “The stories about this radio are legendary,” Robinson said.

At present, portable receivers generally use ferrite rod antennas for LF and MF (below 2 MHz), and whip antennas for HF (up to 30 MHz). Each type has proved effective in its particular application ...
