Mac Amateur Radio Digital Applications

The Mac-Based Amateur Radio Digital Applications - Installation and Integration guide below is a guide for setting up your Mac-based system interfaced with an HF transceiver for operating casually in various modes (e.g.: cw, SSB, digital, etc.), HF digital modes using digital applications (the main thrust of the document), or in contesting.

Capabilities being addressed from a Mac-based processing platform are:

• Radio setup

• Mac setup

• Logger and digital applications’ interfacing and configuration

• Logging

• Call Book or call lookup data

• Digital signals’ encoding and decoding. While the main digital signals being covered are PSK31 and FT8, others can be processed with their respective applications.

• Contesting

• Operational perspectives

• Problems or “gotchas”

The primary and Mac-based applications addressed are: MacLoggerDX (MLDX), fldigi, and WSJT-X. SkookumLogger and WinKeyer USB (with the MacWinKey app) are now included too. The Mac is a current MacBook Pro (16-ich, M1, 2021) running MacOS 12.5 - Monterey. The HF transceiver described is a Kenwood TS-990S HF/50MHz Transceiver – other late model Kenwood HF transceivers may also be quite successful since being within the Kenwood family. As with the hardware, each of the applications described and highlighted are current, up-to-date, versions.

The catalyst and then goal for this guide several years ago was documenting the many various configurations and settings in how things came together and successfully worked. Hopefully, that will also save you from going through the hassles and frustration that I experienced – the hours, days, and weeks trying to tie-up various and fragmented bits of information, those that appeared to help at times, those that led down many “bunny holes”, and in discovering ways until finally getting it right. That was especially true for configuring and integrating fldigi with MLDX. There may even be some "nuggets" of information in there too.

The information, details, and recommendations are those of the author as leveraged from what was learned from the applications’ documentation and corresponding with a few persons such as Don Agro, VE3VRW; Tom Lindner, DL2RUM; and Dave Wright, K3DCW. What is being presented is what worked. There is no intent in countering any information from any online or product documentation source.

RUMlogNG as the logger is being considered for being completed at a later date. RumlogNG wsa integrated and working previously with the digital applications referenced.

There are a few areas where some further work is needed (e.g.: WSJT-X Memory Allocation, operations). Those areas should be updated soon, but should not deter or take-away from the overall focus and content.

Of course, your comments, ideas, suggestions, and feedback are very much welcomed. The Mac-Based Amateur Radio Digital Applications - Installation and Integration document will be updated as needed for corrections, updates, and revisions.
