Mac-Ghpsdr is a version of ghpsdr v2 with changes to make it run acceptably on the Mac by Jeremy McDermond (NH6Z).

MacHPSDR is a native Cocoa implementation of an HPSDR receiver. It uses currently John Melton's modified DttSP from ghpsdr to do the DSP work, but replaces out everything else with native Objective-C and Cocoa technologies. The current author and maintainer of the code is Jeremy McDermond (NH6Z).

Individual software Project Wiki Pages

  • ATHENA - A software Server module - A project to build OS specific server code, module communication libraries and communication protocol documentation.
  • KISS Konsole - Learning SDR Console - The KISS Konsole is a software project to provide a straightforward, well-commented User Interface to Mercury and other modules.

Building HPSDR Rigs

Hardware Introduction

This is a guide for those new to HPSDR about exactly what hardware you need to be able to use the system.

Support documentation

Documents for user interested in building boards can be found on the Support page.

A Basic HPSDR Transceiver in PANDORA

This page is by John Petrich, W7FU, and provides another example of how a Pandora enclosure can be used for the amateur radio experimenter.

A complete HPSDR transceiver in a Pandora Box

This page provides an example of how to build a transceiver using HPSDR components in a Pandora enclosure, other available hardware and PowerSDR version 1.19.3 software.

A complete HPSDR transceiver

This page provides an example of how to build your own transceiver using HPSDR components and other available hardware and software.

The Antec P183 Solution

This page documents an example of how to build your own transceiver using HPSDR components and other available hardware and software in a traditional a mid-tower PC enclosure.

The Tokyo Hy-Power HL-45B Solution

This page documents an example of how to add a commercial solid state 45 Watt Amplifier to your HPSDR rig.

The Rino R-1 Solution

A smaller PC case solution with an optical drive included.

The Antec Minuet Solution

The smallest PC case solution attempted so far.

Never Short a Penelope by AD9DP

The short paper tells you why you should never operate Penelope into a shorted load.

Using Penelope with a linear amplifier

When using Penelope with a linear amplifier you need to ensure you use enough drive. This paper explains why.

HPSDR Performance Tests

The purpose of these pages are to establish HPSDR performance measurement process standards.

  • ATLAS - Backplane - The Atlas is a passive backplane that all other modules plug into.
  • LPU - Simple Linear Power Unit - The LPU unit takes power from a regulated power supply and steps it to the input needed by Atlas.
  • MAGISTER - USB 2.0 to Atlas Bus Interface - The Magister module is an alternative to OZY.

Primarily Mercury and Penelope related

  • ANTENNA SWITCH - by NT-Electronics - An antenna switch for use with Penelope and Mercury when Alex is not used, also has optional low Noise RX Amplifier for 6 meters
