When I earned my first amateur radio license in autumn of 2017 and purchased a hand-held transceiver, I wanted to know what frequencies, modes, repeaters, and times-of-day that were popular with other amateur operators near me. To accomplish this, I created a heatmap – a grid on a sheet of paper showing hours of the day down the left-hand column, and various modes and frequencies across the top of the page. Over the period of several weeks I listened to my transceiver and placed checkmarks in the grid whenever I heard activity. After some time and effort, I had a visual heatmap representation of the popularity of amateur radio in my area.
It is now two and a half years later and I continue to enjoy the amateur radio hobby, therefore I decided to take this concept to the next level by creating a software application that can run unattended while I am at work or asleep.
I have successfully used the application for:
Determining popularity of local 2-meter and 70-cm analog and digital repeaters
Determining popularity of 2-meter SSB by monitoring 144.200 MHz
Monitoring the International Space Station for unscheduled 2-meter FM voice transmissions on 145.800 MHz
Monitoring popularity of the 40-meter AM calling frequency on 7.290 MHz
Monitoring VHF air band frequencies, amateur simplex frequencies, and rail/public transmissions
Two years ago I experienced an interesting phenomena. An inexpensive (dare I say, plastic) box fan randomly behaved like a low-volume, flat-sounding AM radio whenever positioned next to a window in my home.
I’m out of the professional coding world for ten years, but it hasn’t stopped me from creating a BBS-style online text adventure game in the spirit of TradeWars 2002 and Legend of the Red Dragon using PHP and MySQL.
The yearly goals and objectives (G&O) process in most organizations is often perceived by staff as a mundane HR activity required solely to support year-end performance appraisals. Here’s my thoughts as to how directors and managers can strengthen the process with cross-functional peer reviews.
Like most, I spent the recent year-end holidays reconnecting with family and friends over a tin of homemade Toll House chocolate chip cookies and non-fat cappuccinos. We laughed. We cried. We debated the merits of Agile SaaS deployments and Minimum Viable Product (MVP) delivery.
Executive leadership just gave the go ahead for the PMO to fire-up another project but it feels like staff is already over-capacity to take on more work. Here’s how I built a lightweight, easy-to-sustain project labor demand solution using SharePoint and Excel to measure and prioritize project labor demand.
“Lock the door,” said Alvin, “and have a seat over there on the couch.” The boy said nothing but complied with the request. “On second thought, draw the blinds closed, too. One can never be too careful.”
