QSO PRO – Mobile Ham Radio Logger & CAT Rig Control
The ultimate companion for the modern radio amateur.
QSO PRO is a high-performance, mobile-first ham radio logging app designed for field operations, portable activations (POTA/SOTA/WWFF/IOTA/BOTA/LLOTA/TOTA), and mobile/shack stations. Featuring live transceiver CAT control, real-time multi-program spot feeds with one-tap QSY, automated callsign lookups, and multi-platform log synchronization, QSO PRO streamlines your workflow so you can focus on making contacts, not managing data.
