ch Technical draft for the Microwave Journal May 2022 Modern HF Receivers must fulfill a variety of req. irements e.g. sensitivity, robustness and many others. Key requirements are often directly leading to …

A built-in test source is available enabling the receiver software to estimate and thereafter equalize the fre-quency responses of the analog filters so that they can be combined inside the FPGA to get a 30 …

My receiver is based on the “High Performance Communications Receiver” designed by W7ZOI and K5IRK. It was described in most of the annual ARRL Handbooks in the 1980s.

But after radical modifications, an upgraded R-4C is a good receiver for weak DX signal CW reception on crowded amateur HF bands, thanks to the low phase noise of the R-4C PTO (perme-ability tuned …

The WiNRADiO WR-G313e receiver is a USB-controlled, software-defined high-performance HF receiver (9 kHz to 30 MHz, optionally extendable to 180 MHz). This receiver is intended for …

The R-2368B(V)1/URR is a high-performance, cost-effective, VLF/LF/MF/HF receiver covering the frequency range from 10 kHz to 30 MHz in 1 Hz increments.

A new method for specifying receiver IMD is proposed: measure the absolute power of interferers (IMD products and spurs) against 2Ͳtone input power, with the ITUͲR P.372 band noise levels for typical …
