- 📦PhosphorSWL updated to version 1.2The first version for iPad and iPhone Duo.
PhosphorSWL now runs natively on iPad and across both displays of iPhone Duo, with larger type and a layout opened out for the bigger screen.
On BROADCAST and NUMBERS the search and filters sit open in a column beside the list, with the bands laid out as a grid, so the whole schedule stays in view while you narrow it down.
The interface has been redrawn around a standard tab bar, SCANNER, BROADCAST, NUMBERS, FAV and CONFIG, which opens into a sidebar on iPad.
On iPhone the BROADCAST and NUMBERS filters fold into a single line naming what is set, with the count of matches beside it.
Tap the line to open the filters, and scroll the list to fold them away again, giving the schedule the full height of the screen.
Sort the schedule by tapping the kHz, STATION or UTC heading.

The Broadcast tab gains two new filters. Narrow the schedule to a single language, or to the region a transmission is beamed at, alongside the existing time and band filters. Each list opens with the handful you will reach for most, then the full set in alphabetical order.
Propagation readings work again after a change to NOAA's space weather feed.… more - 🆕PhosphorSWL released on the App Store

About PhosphorSWL
PhosphorSWL is a shortwave broadcast schedule browser and numbers station reference, rendered through the green phosphor glow of a Cold War signals intelligence console. Your phone becomes a monitoring station — a frequency dial, a schedule grid, a station database, and a curated dossier of every numbers station still whispering into the void.
BROADCAST SCHEDULES
Browse over 10,000 shortwave broadcast entries from the EiBi database — the most comprehensive freely-licensed shortwave schedule resource in existence. Filter by frequency band, time, language, and target area. See what's on air right now. Search for stations by name, country, or frequency. Every broadcast entry includes transmission times, languages, target areas, transmitter sites, and signal path maps showing the great circle route from transmitter to target.
Schedule data refreshes automatically from EiBi, keeping your listings current through seasonal schedule changes.
NUMBERS STATIONS
The centrepiece. A personally curated database of known numbers stations — active, historic, and legendary. ENIGMA designators, frequencies, schedules, operators, signal characteristics, and full station profiles assembled from publicly observable facts.
From E06 "Russian Man" still counting for the GRU, to the ghost of E03 "The Lincolnshire Poacher" — the most iconic numbers station ever recorded, silenced in 2008 after decades broadcasting from RAF Akrotiri. The Buzzer on 4625 kHz. The Pip. The Squeaky Wheel. Cuban DGI digital modes. Chinese military networks. Polish intelligence. Every station for which sufficient factual data exists.
This is not a decoder. It is a field manual for the darkest inhabitants of the radio spectrum.
SCANNER
Scroll the entire shortwave spectrum from VLF submarine communications through every broadcasting band. Band headers mark the boundaries. Tap any entry for full details and signal path mapping.
HF PROPAGATION
Live HF propagation conditions from NOAA's Space Weather Prediction Center, derived from the planetary K-index. Band-aware — lower frequencies are more resilient to geomagnetic disturbance than upper HF. The status bar tells you whether the ionosphere is cooperating before you tune in.
THE INTERFACE
Three phosphor colour modes: green (default), amber, and red. Red mode preserves scotopic dark adaptation for night-time listening — the same principle used in military operations rooms, submarine control rooms, and observatory domes.
CRT scanlines. Phosphor glow. A frequency readout rendered in segmented digits. Function key tabs. A UTC clock. No bright colours, no rounded corners, no friendly illustrations. This is a monitoring console, not a lifestyle app.
FAVOURITES
Bookmark any broadcast or numbers station for quick access. Your listening post, organised.
