Currently CloudLogOffline supports following features: - Upload to Cloudlog via API - Query QRZ.com (if 3G/LTE is available) - Connect to Flrig by W1HKJ which e.g. runs on a Raspberry Pi which is connected to the radio and opens a Wifi to interact with CloudLogOffline - Set a CQ QRG if Flrig is not available - Live and post QSOs - Many more
