A Grafana dashboard monitoring QRV's lightning notification backend. The Lightning Worker is UP with an OK status, serving 38 active users with lightning alerts enabled. Four time-series charts span 9:00 AM to ~2:30 PM NYC time, showing a dramatic afternoon surge in detected strikes and flash ingestion rate (peaking near 60 flashes/minute). Notifications sent remained low throughout the day with one urgent alert fired late in the window, while 52 notifications were skipped due to user cooldowns.
A screenshot of QRV on an iPhone. It shows a new page called "Frequency Memory" with filtering options for mode and frequency segment. The list consists of saved frequencies including details such as: a name, frequency, mode, and an optional note. When applicable, solar conditions are integrated automatically.
A ham radio mounted vertical in the passenger footwell of a 2023 Chevy Bolt. It's held in place with a 3D printed sleeve and vertical arm.
"QRV 1.15 release announcement graphic with orange background. Headline reads 'QRV 1.15 is out and better than ever!' with bullet points: Filter faster than an FT2 exchange, Get frequency info at a glance, More widgets. Shows four app screenshots: a dark-themed DXCC country list for the 60m band with a context menu offering options like filtering and alerts; a UTC clock widget; a POTA activity widget showing spot counts by band; and a Band Activity widget displaying 30-minute spot totals per band with solar condition indicators."
A screenshot of QRV showing the new logbook aware alert configuration. Users can now have alerts automatically prune themselves as QSOs or QSLs are completed.
A large barge of some sort heads south on the Hudson River. It's two-tone with a black hull and red top. The picture is taken from a dilapidated concrete pier that has been retrofitted with a bunch.
A screenshot from the Apple Watch prototype of QRV. It shows 4 solar indices across the top and band conditions below, with adetailed day/night breakdown.
A plain white HTML page with the phrase "Silence is Gold" inexplicably added in plain text.
This is QRV's Battery Capacity and Usage calculator. The left sidebar shows the app's navigation structure across Lookup, Conditions, Calculators, Bands, and General sections, with "Battery Capacity and Us…" currently selected. The main content area has two columns. On the left, **Battery Specs** lets the user select chemistry (LiFePO4, LiPo, or Lead Acid via a segmented picker — LiFePO4 is selected), set rated capacity (20 Ah), and see usable capacity (20.0 Ah, ~100%). Below that, **Load** offers an Amps/Watts input mode toggle (Amps selected), TX Draw (22 A), Duty Cycle (SSB ~20% via a dropdown), and RX Draw (0.5 A). On the right, **Results** shows estimated runtime of 4.2 hours in large orange text, a green capacity-vs-draw progress bar (20.0 Ah vs 4.8 A draw), average draw of 4.80 A / 66.2 W, and solar panel wattage needed to sustain operation (79 W optimistic, 132 W realistic). Below the results is a **Chemistry Reference** section with expandable cards for each battery type. LiFePO4 is shown at ~100% usable capacity with a description highlighting full voltage until near-empty, 12.8V nominal, 10V cutoff, and a bold warning about requiring a specific charger. LiPo (~80%) notes energy density, balance charging, and storage voltage. Lead Acid (~50%) describes tolerance of abuse but warns against deep discharge. The footer reads "Battery Capacity and Usage" and the top-right corner shows the grid square FN21XU and current UTC time.

I image of an iPhone. The top section shows the user's current grid square, latitude and longitude, and altitude. Below that, there is a map outlining the current grid square with a pin at the user's location. Below this, we can see a little bit of informational text that needs to be scrolled to.
