Pocket QSO Logger

Pocket QSO Logger is a free, offline-first logbook for amateur
radio operators who log from their phone — at the desk, on a SOTA
peak, or anywhere the radio goes. CW, SSB and FM by design.


◆ FEATURES

– Session-based logging: one operation per station, rapid QSO
entry, and last band / mode / freq remembered between contacts.
– Bluetooth CW keyer: 9A5N QRQ and Pico keyers, six F1–F6 macros,
Instant CW, and live WPM control.
– Yaesu FT-857 / 897 radio control (CAT): live frequency + mode
auto-fill the log; set frequency and mode from the app too.
– cty.dat country / DXCC lookup (AD1C) with live flag, auto band
from frequency, per-mode RST, and a real-time dupe warning.
– Optional QRZ.com lookup for name, QTH, country and grid.
– Maps with brass pins and great-circle paths — per operation and
for your whole logbook.
– Custom callsign keyboard, Indoor / Outdoor / Auto themes, ADIF
share and full JSON backup.


Free, no ads, no required account, no cloud sync. Optional
analytics and crash reporting are off by default — decline them
and your data stays on the device.

QRZ.com credentials, if saved, are encrypted with AES-256-GCM via
the Android Keystore.

73 and good DX.
