1. Reminders are a table again. Every combination of band and mode used to be a chip of its own, four to a row, with the band name repeated on each and the row breaking in the middle of a band. At twelve bands and four modes that still read; with 60m and FT4 there are sixty-five of them, and the screen became a wall. The band is now named once on the left and the five modes stand in columns — a single line answers what is on for twenty metres. It is the same screen the iPhone version has.
2. Switching a combination off keeps its exact frequency. Unticking one in the edit window used to delete it, along with the frequency and tolerance set for it. It is now only switched off, so turning it back on brings the frequency back.

1. The app knows when it has grown too old. Until now it could only say that a newer version exists. It now also learns from ly4a.com whether this one is still supported: a version that has fallen behind is asked to update at every start, and one that is no longer supported shows only the download screen until it is. Nothing changes today — the limits are set on the site when they are needed. Your callsigns and reminders survive the update either way.

1. Your own alarm sound. Until now the alarm always used the default alarm tone of the phone. Settings now let you choose one of the system alarm sounds, or any music file on the phone. If that file is later deleted, the system sound comes back rather than the alarm falling silent.
2. A warning when the phone is holding the alarm back. Android 14 and later give full-screen alarms only to apps they treat as alarm clocks, and battery saving can pause the watching — neither of them says so. Settings now check both and lead straight to the right system screen.
3. The spotter shows on a paired watch too. The alarm notification draws its own buttons so that Stop and Snooze are reachable without opening it, and a watch skips that drawing — leaving only the frequency and mode. The spotter and the source now travel with the notification itself.

1. Ketuk Download Android APK. Browser mungkin memperingatkan tentang jenis file ini - izinkan saja.
2. Buka file yang sudah diunduh. Android akan meminta izin memasang aplikasi dari sumber ini: aktifkan untuk browser kamu, lalu kembali.
3. Ketuk Install, lalu Open.
4. Saat pertama kali dibuka, izinkan notifikasi - tanpa itu alarm tidak bisa muncul.
5. Jika aplikasi meminta Alarms & reminders, izinkan juga, kalau tidak pemeriksaan bisa tertunda oleh sistem.

Aplikasi ini tidak ada di Google Play, itulah sebabnya ponsel meminta izin. Tidak perlu akun dan tidak mengumpulkan data apa pun.

1. Unduh file .msi dan jalankan.
2. Windows mungkin menampilkan "Windows protected your PC". Klik More info, lalu Run anyway - aplikasi ini tidak ditandatangani dengan sertifikat berbayar, dan hanya itu arti peringatan tersebut.
3. Ikuti proses instalasi. Kamu akan mendapat entri di menu Start dan pintasan di desktop.
4. Menutup jendela tidak menghentikannya: aplikasi tetap memantau dari system tray. Keluar melalui menu tray.

1. Buka file .dmg yang sudah diunduh dan seret LY4A DX Reminder ke Applications. Keluarkan disk image-nya.
2. macOS 12-14: di Applications, klik kanan aplikasinya dan pilih Open, lalu Open lagi di peringatan. Klik dua kali biasa tidak memunculkan tombol Open.
3. macOS 15 (Sequoia) dan yang lebih baru: coba buka, lalu masuk ke System Settings → Privacy & Security, gulir ke bawah dan klik Open Anyway.
4. Jika muncul "damaged and can't be opened", filenya tidak apa-apa - begitulah cara macOS menyebut aplikasi yang tidak ditandatangani. Buka Terminal dan tempel:
   xattr -dr com.apple.quarantine "/Applications/LY4A DX Reminder.app"

Hanya perlu sekali. Menandatangani aplikasi akan menghilangkan peringatan itu, tetapi memerlukan akun developer Apple berbayar.
