I go by “JJ”.

The website's pages are still in-work with more to come in the future. They seem to be updated when needed since going "live" -- "typos" and spelling errors are being corrected when seen along with addiional content being added. One area still being worked is "fleshing-out" the Projects tab. The website has only been active or "up" since November 2020.

CW Proficiency (after all of these years)

There is a strong interest in getting back into CW building proficiency, skills, and speed -- basicallly, I want to be better and more comfortable with it.

There was the time in the mid-to-late 1980s when somewhat proficient making regular CW QSOs from my Texas QTHs progressing from around 5WPM as a Novice to 20WPM as an Extra. Then, with heading OCONUS for work with my wife of 2 years in early 1990, I just sort of "dropped" operating CW though remaining active with SSB and digital modes.

After 30+ years now, the desire to be comfortable with CW has returned. In rediscovering CW, a structured daily approach needed to be established. Acting on that desire, I signed up for the CW Ops CW Academy (CWA) Basic Class during the summer of 2021. That CWA's SEP-OCT21 Basic Class and the Intermediate Class (JAN-FEB22) have been completed. Wanting more proficiency, I requested to "redo" the CWA's Intermediate Class for the MAY-JUN22 session. I plan on contributing as an Associate Advisor for my CWA Advisor's Beginner Class for the SEP-OCT22 session.

If you are interested in having an occasional or even a regular QSO working on brushing-up your CW operating skills as I am, then please reach-out to me via an email message to jj@wr5e.net.

Mac-Based Amateur Radio Applications

The Mac-Based Amateur Radio Applications guide started as a personal project documenting configuration challenges and trials mainly getting fldigi configured and logically integrated with MacLoggerDX (MLDX) using a Macintosh computer (Mac) and a Kenwood TS-990S HF/6m Transceiver during 2018. WSJT-X and its configuration and integration with MLDX were also documented. I figured that if I struggled with the configuration and integration with MLDX, fldigi, and WSJT-X and succeeded; then there may be others "out there" that could benefit. The result is a living document able to be viewed and downloaded from the Amateur Radio/Mac Amateur Radio Digital Applications webpage. The regret is not getting this out sooner.

Portions of the guide were updated after personally transitioning to MacOS 11.0 Big Sur recently (in late November, 2020). The updated guide remains relevant to those staying with MacOS 10.15.7 Catalina or even earlier MacOS versions, and now with those using MacOS 11.n, Big Sur; or now with 12.n, Monterey.

There is also a new section in the Amateur Radio/Mac Amateur Radio Digital Applications webpage detailing the versions recommended/required for MLDX, WSJT-X, and fldigi to successfully run on MacOS 11.n, Big Sur; or with 12.n, Monterey.

The guide has also been updated for the WSJT-X application update. The recently released WSJT-X ver. 2.3.0 accommodates both the Mac's Intel processor along with the new M1 processor. The basic change for being able to run the application for either processor is with updated memory allocation parameters.


An update to the guide has been started. The update is needed due to some changes with the Mac peripheral hardware (nothing that changes the processing functionality though), general clean-up, and version updates (MacOS, WSJT-X and fldigi version updates - current versions of each are being used with no apparent deviations from what is already documented in the guide). I am also looking to get the previously incomplete RUMlogNG section or appendix finished and reinserted, incorporating the more recent SkookumLogger application addition (used just for contesting), and the including the K1EL WinKeyer USB keying unit. Getting the updates captured should make the guide a bit more universal for current or future Mac-based ops.

Old VK8JJ website persists on qsl.net

The first attempt creating a website still languishes "out there" on qsl.net at https://www.qsl.net/vk8jj/. It was created shortly after returning to Alice Springs in APR98. Unfortunately due to work and family, it was never updated after moving to another residence about a year later (where we lived for another 5+ years until returing back to the US and Colorado in 2004). It had been several years since last seeing it -- thinking that it might have been deleted.
