began by first making a list of the fea-tures and specifications I wanted in a high performance transceiver. Then I began draw-ing various circuit blocks that, combined together, would meet the requirements of my wish list of features. The HBR-2000 block diagram is shown in Figure 1.
This document summarizes a homebrew high performance HF transceiver built by VE7CA called the HBR-2000. It describes how VE7CA divided the project into small testable modules and built each module individually, testing it before moving on.
This page provides a brief description of the receiver portion of a HF (160 to 6 meters) High Performance Transceiver that I built. I named it the HBR-2000. HBR is short for homebrew and 2000 is the year that I first heard a signal from the receiver speaker.
HBR-2000 HF 9-band High Performance All-Mode Transceiver This page provides a brief description of the receiver portion of a HF High Performance Tranceiver that I have built. I named it the HBR2000. HBR being short for homebrew and 2000 is the year that I had my first CW QSO with the rig.
HBR-2000 architecture. The receiver is a single-conversion receiver with no RF amplifier. The receiver mixer is a high-level +17 dBm double-balanced mixer followed by a single-stage classic W7ZOI-design 2N3688 post-mixer amplifier, then a 6 dB pad. Five select-able, relay-switched, crystal IF filters are located between the post-mixer am-
