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

trx-control is not a standalone app. It requires a trx-control(7) installation with a running trxd(8) daemon that has WebSockets enabled. The app connects to trxd(8) using a WebSockets and displays all transceivers and extensions that have been configured for client access. The trx-control app is mainly used by radio amateurs to operate transceivers and other hamradio related hardware. Please note that in order to use the callsign lookup feature, a valid QRZ.com subscription is needed.
