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. Ketik Muat Turun Android APK. Pelayar anda mungkin memberi amaran tentang jenis fail ini - benarkannya.
2. Buka fail yang dimuat turun. Android akan meminta untuk membenarkan pemasangan aplikasi daripada sumber ini: hidupkan untuk pelayar anda, kemudian kembali.
3. Ketik Pasang, kemudian Buka.
4. Semasa pelancaran pertama, benarkan pemberitahuan - tanpanya, penggera tidak dapat muncul.
5. Jika aplikasi meminta Penggera & peringatan, benarkan juga, jika tidak pemeriksaan boleh dilengahkan oleh sistem.

Aplikasi ini tidak terdapat di Google Play, sebab itu telefon bertanya. Ia tidak memerlukan akaun dan tidak mengumpul apa-apa.

1. Muat turun fail .msi dan jalankannya.
2. Windows mungkin memaparkan "Windows melindungi PC anda". Klik Maklumat lanjut, kemudian Jalankan juga - aplikasi ini tidak ditandatangani dengan sijil berbayar, dan itu sahaja maksud amaran ini.
3. Ikut pemasang. Anda akan mendapat entri menu Mula dan pintasan desktop.
4. Menutup tetingkap tidak menghentikannya: aplikasi terus memantau dari dulang sistem. Keluar daripadanya melalui menu dulang.

1. Buka .dmg yang dimuat turun dan seret LY4A DX Reminder ke dalam Aplikasi. Keluarkan imej cakera.
2. macOS 12-14: dalam Aplikasi, klik kanan aplikasi dan pilih Buka, kemudian Buka sekali lagi dalam amaran. Klik dua kali biasa tidak memberikan butang Buka.
3. macOS 15 (Sequoia) dan lebih baharu: cuba bukanya, kemudian pergi ke Tetapan Sistem → Privasi & Keselamatan, tatal ke bawah dan klik Buka Juga.
4. Jika ia berkata "rosak dan tidak dapat dibuka", fail itu okay - begitulah cara macOS menerangkan aplikasi yang tidak ditandatangani. Buka Terminal dan tampal:
   xattr -dr com.apple.quarantine "/Applications/LY4A DX Reminder.app"

Hanya diperlukan sekali. Menandatangani aplikasi akan menghapuskan amaran tetapi memerlukan akaun pembangun Apple berbayar.
