Everything You Need to Log QSOs

Whether you're operating portable, at home, or chasing DX — QSL Buddy has the features to make logging fast and effortless.

Core Logging Features

Designed for speed and simplicity

Quick QSO Logging

Log contacts in seconds with minimal typing. Smart prefix suggestions for VHF/UHF local contacts, quick-select RST buttons, and automatic country detection from callsign prefixes.

Smart Prefix Suggestions

On VHF/UHF bands, QSL Buddy remembers your last contact's prefix and suggests it for the next contact. Perfect for logging multiple contacts on the same repeater or local net.

RST Quick-Select

Tap to select RST reports instead of typing. Common values (51-59) are just one tap away. Both sent and received RST are tracked.

Country & Activity Detection

Automatically detects the country from callsign prefixes. POTA, SOTA, WWFF, and IOTA references are parsed and logged from DX spot data.

Callsign Lookup

Automatic lookup via Callook.info (US) and HamQTH (international). See operator name, QTH, grid, and LoTW/eQSL status instantly.

Speech-to-Callsign

Hands-free callsign input using NATO phonetic alphabet speech recognition. Say "Golf Four Lima Romeo Victor" and get G4LRV entered automatically.
