Everything it can do.

Spectrum and waterfall

You see the whole band at once. Zoom in, pan around, click straight on a signal.

Analogue and digital

FM, AM, SSB, and on top of that DMR and TETRA. One SDR, one program, every mode.

DMR decoding

You hear DMR calls and see who is talking: radio ID, talkgroup, slot and colour code. Every call goes into the log by itself.

DMR trunking

The program holds the control channel and, on Tier III (in beta for now), follows the calls onto the traffic channels. Capacity Plus, Connect Plus and Hytera XPT it recognises and writes to the log.

Up to five receivers

Listen to several frequencies at once from a single radio: up to five VFOs with an SDRplay, up to three with other receivers.

Stations on a map

APRS positions land on the map by themselves, together with movement history.

Speech to text

The program turns what you hear into text. Everything is computed on your own machine, and nothing goes to the network.

Satellites and Doppler

A pass list, a sky chart and a receiver that keeps up with the satellite on its own.

dPMR decoding

One button and you hear dPMR calls. You see the station ID, the talkgroup and the colour code, and every call goes into the log by itself.

RTTY teleprinter

A page of its own for the RTTY decoder. In Auto mode the program works out the speed and shift by itself, from amateur 45.45 Bd to DWD weather, and every transmission received goes into the log.

Morse to text

The CW decoder turns dots and dashes into readable text in the log.

FT8 and FT4

Both modes from one audio stream, and beside them a QSO map with a line to every station heard.

433 MHz sensors

Weather stations, tyre pressure sensors (TPMS), gate and blind remotes. One button covers the whole 433 MHz band, and a double-click on a row shows the packet details, which you can also save as WAV.

Aircraft on the mapv2 ONLY

ADS-B positions from your own receiver on the home network, which the program finds with one button, or with no receiver at all from adsb.lol. Plus airports, navaids, airspaces, METAR weather and 3D aircraft models.

Tactical map

MIL-STD-2525 symbols, routes with bearings, coordinate grids and export to PNG.

Propagationv2 ONLY

Where and on which band there is a path right now: an HF coverage map, the best DX directions, a forecast for the coming hours, space weather, VHF, EME and the grey line. The VOACAP model on NOAA data.

Band scanner

It sweeps the band and stops when someone transmits. It ignores spark clicks, mirror images and intermodulation, warns you of overload, and in v2 listens to several signals at once and learns the interference.

Translation

The text translated into your language straight away. Offline as well, next to the original.

Transcription that keeps up

The new speech recognition engine uses several times less CPU, checks by itself which model keeps up on your computer, and saves the log to PDF as well.

Keyword alerts

When a chosen word comes up in the transcription (inflected, misspelt or in the phonetic alphabet), the program lets you know and tunes to that frequency with one click.

Radio tables

A wizard for your communications plan (nets, frequencies, passwords and codewords) with export to PDF and PNG and the frequencies sent straight to Channels.

Sound under control

Equaliser, filters and a noise gate. Set it once, it works on every audio path.

Auto squelch

The program sets the squelch threshold to the noise on the band by itself, and Denoise cleans up the voice. Both switches are on the SDR page, in both looks.

Second monitor

Right-click a page to tear it off into a window of its own. The waterfall alone as well, without the rest of the SDR panel. Closing the window hands the page back.

Full screen

The window frame and the sidebar fold away at one keypress. What is left is the spectrum, the waterfall or the map, filling the screen.

New versions announce themselves

From version 2.3 the program checks by itself whether a newer version is out and tells you with a Windows notification. Short messages from the author come the same way. You can switch both off in Settings.

Light and frugal

The classic look takes about 17 MB and needs no modern graphics card, so it runs smoothly on older computers too.
