MultiScan SDR PRO Coming soon
Several SDR sticks. One scanner.
And it tells you what it hears.
MultiScan SDR PRO is the extended edition of MultiScan SDR for several receivers at the same time. Airspy, RTL-SDR, HackRF and the other supported sticks work side by side in one program and share the audio mix, the log, the frequency database, lockouts and the web control. With a single stick PRO looks and works exactly like the normal MultiScan SDR.
Every stick gets its own task
One dropdown per stick decides what it does.
- Scanner – sweeps its own scan ranges, e.g. stick A the airband and 2 m, stick B the 70 cm band.
- Listener – hold a VFO with ⏸ on a scanner stick and a free listener takes it over within a fraction of a second; the scanner keeps sweeping.
- Fixed-frequency decoder – ADS-B 1090 MHz, AIS or 433 MHz sensors run on their own stick while the others scan.
- Same frequency on two sticks? Only the stronger VFO stays.
- Sample rate per stick – all sticks share the USB bus; PRO shows when a stick gets too little data.
Overview, tabs and windows of their own
The overview shows every stick one below the other – waterfall, pseudo-spectrum and the measured load (received vs. nominal sample rate). Each stick also has its own tab, and any tab can be popped out into a window of its own, e.g. on a second screen, with its receiver and scanner control on the left.
- Per stick: own lockout list (optionally plus the lockouts of stick A), own scanner control – threshold, VFO limit, hold time – and own classifier settings.
- Shared: audio mix, recording, speech to text, logs, frequency database, decoder tables and web control.
Signal classifier
What is that on 438.300 MHz? For every open VFO PRO looks at the channel signal itself and shows what is probably sent there – with a confidence, right on the channel card.
- What it measures: bandwidth, carrier share, envelope (constant for FM and FSK), the frequency levels and their shift, the symbol rate, the PSK order and the rhythm of speech – every quarter or half second.
- What it recognises: FM and AM voice, tones, bare carriers, POCSAG, FLEX, 2-FSK, GMSK, DMR-like 4-FSK, BPSK/QPSK/8PSK, OOK, packet radio (AFSK 1200), ACARS – or just noise.
- Certain when decoded: when a decoder really decodes the signal (POCSAG, FLEX, packet radio, ACARS) it is marked “✔ decoded”.
- It can act: release VFOs that only hear noise, lock unmodulated carriers temporarily, switch the matching decoder on.
- Everywhere: on the channel cards (hover for the measured values), in a “Signal” column of the logs and in the web control.
Signal analyzer
Right-click into the spectrum ▸ “Send to classifier”: the stick stays on that frequency and the analyzer tab shows up to ±100 kHz around it – waterfall and spectrum with peak hold. Drag over a signal with the mouse and the marked range is analysed continuously.
- Verdict: what kind of signal it probably is, with confidence and the other candidates.
- Data or voice: how sure it is a data transmission – and how sure it is speech.
- Facts: modulation, symbol rate, frequency levels and shift, bandwidth, SNR, deviation, envelope.
- Constellation of the symbols and the PSK rose (phase change per symbol).
- Eye diagram of the frequency (FSK) or of I (PSK).
- Histograms of frequency and envelope, the symbol-rate spectrum with the detected rate and the audio spectrum.
Availability
Coming soon
PRO is being tested with Airspy, RTL-SDR and HackRF at the moment. Release date and price follow on this page. PRO needs a PRO key of its own – the codes of the normal MultiScan SDR do not unlock it. Without a key PRO runs like the free version with one receiver.
