iFunctionGenerator turns your iPhone, iPad, or iPod Touch into an audio function generator. You can have up to 20 generators, each operating at a different frequency. Each generator can be one of the following types: • Sine Wave • Triangle Wave • Sawtooth Wave • Square Wave • Pink Noise • White Noise The volume of the left and right channels can be independently controlled, and may be set using either a slider for ease, or direct entry of the volume, for maximum precision. The relative phase of each channel may also be set. Frequencies from 1 to 20,000 Hz may be entered. The phase can vary between -360 to 360 degrees. The volume may be between 0 and 100 percent. The mute button makes it easy to quickly silence the audio generators. You can take snapshots of the generator settings. This lets you build a library of settings, and quickly load the desired settings.

SVX Portal is a fast, focused companion for the SvxLink SvxReflector network. Point it at your reflector domain and instantly see who's on the air. LIVE LAST-HEARDS Watch a real-time list of stations as they key up. Active talkers are highlighted with a live timer; past stations show how long ago they were last heard. LISTEN IN Tap a talkgroup to listen to live, low-latency Opus audio — one talkgroup at a time. The compact, sliding Listen bar stays out of the way so the last-heards list keeps centre stage. Switch on background listening to keep audio playing when you change apps or lock the screen. MAP See repeaters and hotspots on a clean map, colour-coded by status — online, transmitting, hotspot, or offline. Tap a station for its details (TX/RX, CTCSS, location) and centre the map on your own location with one tap. Overlapping stations fan out so nothing stays hidden. SIMPLE SETUP Everything is driven by a single reflector domain. Talkgroup names are fetched automatically and the audio stream is configured for you — no accounts, no clutter. MADE FOR YOUR DEVICE • iPhone and iPad • Choose your orientation: Auto, Portrait, or Landscape • Keep-screen-on option for the shack or mobile SVX Portal is built for licensed amateur radio operators using SvxLink-based reflector networks. It's a receive-and-monitor companion — listen, watch, and explore your network at a glance.
