Accessing this interface provides entry to one of the largest databases for amateur radio voice repeaters, encompassing over 8000 entries from more than 60 countries. The resource supports both desktop and mobile access, with a default display based on browser type, or forced via a "force" parameter (e.g., relais.dl3el.de?force=mobile). Users input a QTH-locator to find local repeater information. The database integrates FM-Funknetz servers and hotspots, potentially creating duplicate entries but ensuring new FM-Funknetz repeaters are immediately displayed. DMR repeater information, including status and talkgroup configurations, is sourced directly from DMR+ / ircDDB and Brandmeister systems, with real-time updates for active and default talkgroups. C4FM/Wires-X installations, particularly MMDVM-based gateways not listed in Yaesu's database, are identified through Brandmeister dashboard descriptions, marked with "W-x" or "W-x#MMDVM" for manual entries. D-Star repeater data from ircddb or QuadNet2 is also incorporated, with entries marked (i), (o), or (d) for manual additions. An APRS interface allows searching by callsign, using Sassan, DL3NCK's database, and offers a mobile-friendly, auto-refreshing display that follows an APRS station. Output data can be generated in GPX format for offline smartphone maps or CSV for spreadsheet applications. The database also attempts to determine valid repeater offsets based on IARU region and frequency, indicated by a "." after the frequency.

Lido Radio Products specializes in **no-holes mounting solutions** for a wide array of mobile electronic devices, including amateur radio transceivers, smartphones, and tablets. Their product line features cup holders, vent mounts, and window mounts, designed to secure equipment without permanent modifications to a vehicle's interior. The company supports various brands such as Icom, Yaesu, Kenwood, Motorola, Hytera, and Vertex, catering to both amateur radio operators and land mobile users. My own experience with similar mounting systems for mobile operations confirms the utility of a secure, non-invasive setup. A stable mount prevents equipment from becoming a projectile during sudden stops or turns, a critical safety consideration for any mobile station. Lido's focus on specific radio brands suggests a tailored approach to fit and function. They also provide individual parts to customize existing mounts, allowing operators to adapt solutions to unique shack or vehicle configurations. This modularity is a significant advantage for hams who frequently reconfigure their mobile setups or integrate new gear.

How to program Baofeng handheld transceiver with satellite frequencies, and how to get alerts when satellites are visible by using a smartphone app. A beginners guide to work satellites with a common VHF handheld radio.

For a lightweight portable station, all you need is a handheld transceiver, a tiny packet TNC, and an Android smartphone.

Manufacture remote control interfaces to manage several kind of ham radio transceivers, Antenna rotators and antenna switches. Control can be done using smartphone Apps or from Computers.

Decode DTMF from your iPhone. Hold your smartphone close to a DTMF source and this app will decode the numbers being dialled.

Use your Smartphone as an Oscilloscope to visialize signals from 150 Hz to 15kHz and as a Signal Generator to generate sinusoidal, square and triangular signals up to 15kHz

The RemoteTx ham radio remote control system is an economical way to control your amateur radio station through the Internet with a phone, tablet, Mac or PC. There are 3 main parts to the solution. Conveniently operate your station with a smartphone, tablet or laptop anywhere you have Internet access.

A remote rotor controller, you can use to connect your laptop tablet or smartphone directly to the rotor using it as a Acces point or alternatively it can be connected to existing Wi-Fi network

Ribbit is a novel digital text messaging mode for VHF/UHF communications for recreational and emergency use which radically increases the density of information transmitted by spectrum used. It leverages the computing power of the modern smartphone to increase the capabilities of any Handy Talkie without requiring any additional hardware or cable. A Ribbit message is fixed in duration at 1250 milliseconds. It is sent over audio modulation with a 2kHz bandwidth centered on 1.5kHz. It is preceded by 400ms of white noise to open analog squelch circuits.

Documents the design and construction of a **four-band Moxon beam** antenna, covering 20, 15, 10, and 6 meters. Author W7JMP shares his journey from initial research and computer modeling using 4NEC2 to the final on-air testing and optimization. The project aimed for gain over a dipole on 20 meters, with a budget under $500, including the antenna rotor. The design incorporates fiberglass spreaders and a single feedpoint, avoiding complex relay switching. The article details the selection of materials, assembly techniques, and the critical tuning process. W7JMP describes fabricating the hub, mounting spreaders, and attaching elements made from stripped THTN wire. A notable innovation is the use of a half-wave tuning stub with a loading coil for in-situ adjustment of the 20-meter reflector, optimized via remote S-meter readings using a webcam and smartphone. This method allowed for fine-tuning the **front-to-back ratio** without lowering the antenna. Initial testing revealed a dipole-like pattern, which was significantly improved after tuning, resulting in reported 2 to 4 S-unit front-to-back ratios and enhanced signal strength for DX contacts on multiple bands, including sporadic E on 10 and 6 meters.

A tiny board, which allows a smartphone or similiar device to connect to the Baofeng UV5R radio via a TRRS audio connector. It allows for connecting the radio to a software TNC app such as APRSDroid or PocketPacket. Solder on the components, solder on the cables, then provide some stress relief, (I use solid-core wire and heat shrink tubing), and you can use your UV5R with your smartphone for APRS on the cheap.

The Meshtastic project leverages _LoRa_ radio protocol to establish a long-range, off-grid communication platform, functioning as a decentralized mesh network. It facilitates sending and receiving text messages using inexpensive LoRa radios, eliminating reliance on traditional infrastructure or a smartphone for core mesh communication. Key features include encrypted communication, extended battery life, and optional GPS-based location services, with radios designed to rebroadcast messages to ensure delivery across the mesh. This system has demonstrated a record range of **331km** and is entirely community-driven and open source, with its codebase hosted on GitHub. Unlike conventional amateur radio, Meshtastic operates on LoRa frequencies generally accessible without specific licenses. Each Meshtastic radio can pair with one phone for message exchange, and support is provided by volunteers.
