HAM QuickLog vs rtl_tcp SDR

Log contacts in seconds, not minutes. HAM QuickLog is the complete HAM radio app combining lightning-fast logging with 11 built-in tools, perfect for casual operators, POTA activators, contesters and SWLs. Why operators choose HAM QuickLog: * Purpose-built templates: HF, SWL, Contest, POTA, minimal and Full templates show only the fields you need * Lightning-fast entry: Auto-fill some fields, field copying, and smart defaults minimize typing * Works anywhere: Includes several online and 6 fully offline tools (Grid Calculator, Azimuth Calculator, Q-Codes, UTC Clock, ITU Prefixes, My Grid & Location) * Zero paper in the field: Log directly on your iPhone or iPad, no transcribing later Home Screen Widget: See your latest QSOs and log stats at a glance — right from your Home Screen. No need to open the app. PDF creation: Generate a clean, printable PDF of your log. Print it directly from the app or share it — perfect for club submissions, personal archives or Field Day documentation. Built-in HAM Tools: * DX Cluster * Contest Calendar * Grid & Azimuth Calculators * QRZ & HamQTH Browsers * SOTA Cluster * Q-Codes Reference * ITU Callsign Prefixes * UTC Clock * And more Professional features: * Full ADIF import/export * Automatic duplicate checking (Contest mode) * One-tap callsign lookup (QRZ & HamQTH) * Dedicated SWL template * Works on iPhone and iPad Perfect for: * Quick portable logging on iPhone or iPad * POTA activators logging from parks * Contest operators needing speed * Field Day operations * SWLs tracking what they hear * Home station everyday logging Whether you're activating a park, working a contest, or enjoying casual QSOs, HAM QuickLog keeps you on the air - not buried in paperwork.

An RTL-SDR Software Defined Radio receiver app for iOS devices.  Listen to AM, FM, SSB and CW radio signals. View an RF spectrum and waterfall. Connect, via the rtl_tcp network protocol, to networked RTL-SDR USB peripherals. This app requires an external rtl_tcp server. iOS devices do not currently support the direct connection of USB peripherals such as an RTL-SDR. Thus, the use of this app requires network access to a server, such as a Raspberry Pi (or Mac), with an RTL-SDR unit plugged into its USB port, and running the rtl_tcp protocol at an TCP/IP network address accessible from your iOS device. This allows a Raspberry Pi (or Mac) to act, essentially, as the USB port adapter for your iOS device. The rtl_tcp SDR app can also connect to hfp_tcp for the Airspy HF+, rsp_tcp for SDRPlay devices, and lmm_tcp for the LimeSDR Mini; see GitHub for server source code. This app can also connect to a Hermes Lite 2 QRP transceiver directly, if it has a known IP address, or through an hl2_tcp server. No support is provided for installing any of the rtl_tcp or other tcp software needed to use this app (with a Raspberry Pi, or otherwise). Please do not download this app unless you are already familiar with Software Defined Radio, have an RTL-SDR or equivalent USB SDR peripheral, and have already installed and tested rtl_tcp on your Raspberry Pi, Mac, or other server. Note that this app requires a very high bandwidth network connection in order to receive streams of real-time RF samples from an RTL-SDR. It is recommended that your rtl_tcp server be on a wired connection rather than on the same WiFi as your iOS device.
