Fascinated with Program/Project Management, Systems Engineering, RF, Analog, and Digital ("ones and zeros"), and Amateur Radio!
I go by “JJ”.
The website's pages are still in-work with more to come. 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 being worked is further content under the Projects tab.
The website has been active since November 2020.
CW Proficiency (after all of these years)
A strong interest persistes getting back into CW building proficiency, skills, and speed. Basicallly, I want to be better and 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 5-7WPM as a Novice to around 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 over the years.
Now 30+ years later, 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) classes in 2021 and 2022
If you are interested in having a QSO working on brushing-up your CW operating skills, then please reach-out to me via an email message to firstname.lastname@example.org.
Mac-Based Amateur Radio Applications
The much revised Mac-Based Amateur Radio Applications guide can be viewed and downloaded from the Amateur Radio/Mac Amateur Radio Digital Applications area.
The guide is focused on an M1 silicon-based Mac – my personal MacBook Pro (16-inch, 2021) recently transitioning to MacOS 14 (Sonoma), with a Kenwood TS-990S; M2 Macs should not be an issue. Older Intel silicon-based Macs can also effectively run the logger and the applications as presented in the guide. Examples include a MacBook Pro (15-inch, mid-2015) running MacOS 12 (Monterey) used by my youngest son, Kris, KF0KVY, with a Kenwood TS-590S. An even older MacBook Air (mid-2012) running MacOS 10 (Catalina) was used by my oldest son, Nate, KD5OCU, with an Icom IC-7300; he now uses a MacBook Pro (16-inch, 2021) running MacOS 13 (Ventura).
Shortly after starting the guide's update, a significant revelation appeared – the topic areas previously believed to be logically presented just were not. The areas were found to be fragmented where you needed to go back and forth between areas to make sense of it all. Yes, there was a lot of information and details, but the “flow” in how things initially come together, and then build from, was missing. With that, this revision’s focus evolved to its restructuring and quite a bit of rewriting getting some logic into the flow of events needing to occur prior to subsequent events happening. My hope with this version is now having the various parts in a more straightforward or aligned approach.
A recenlty acquired Yaesu FT-710 HF/50MHz Transceiver (bought at the 2023 Dayton Hamvention) has been integrated (with difficulty).
The primary equipment and software covered in the Mac-Based Amateur Radio Applications guide includes:
MacBook Pro (M1, 2021) running MacOS 13 (Sonoma)
MacBook Pro (Mid-2015) running MacOS 12 (Ventura)
MacBook Air (2012) running MacOS 10 (Monterey)
Kenwood TS-990S HF/50 MHz Transceiver
Kenwood TS-590S HF/50 MHz All Mode Transceiver
Icom IC-7300 HF/50 MHz Transceiver
Yaesu FT-710 HF/50 MHz Transceiver
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 MLDX using a Macintosh computer (Mac) and a Kenwood TS-990S HF/50 MHz Transceiver during 2018. WSJT-X and its configuration and integration with MLDX were also documented. I figured 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.
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.
