FreeDV RADE

FreeDV RADE

Built-in FreeDV RADE digital voice (the Radio Autoencoder, V1 and V2) on RX1, RX2 and transmit, ported from Thetis-RADE by Christos Nikolaou, SV1EIA. No separate FreeDV program or virtual audio cables needed.

Using it

1. Open Modes > FreeDV in the menu bar (FreeDV on its own in the Classic layout).
2. Pick RX1 or RX2 and press RADE. The receiver switches to DIGU or DIGL, and received RADE is decoded straight to speech.
3. Transmit as normal: your overs are sent as RADE, with your callsign in the end-of-over frame.

The FreeDV window shows sync, SNR, frequency offset, levels and the last callsign heard. Settings (callsign, levels, mic noise reduction, AGC and EQ) are in Setup > DSP > FreeDV (RADE).

On the panadapter

While a receiver has RADE on, its panadapter shows sync, SNR, level, clip and the last callsign at the top right. RADE readings can also be added to meter containers (Setup > Appearance > Meters/Gadgets).

FreeDV Reporter

The Reporter button in the FreeDV window shows who's on RADE right now (qso.freedv.org), by band or following your frequency. Double-click a station to tune to it. Stations transmitting show in red, just heard in green, and new messages in plum.

To appear on it yourself, tick Report my station in Setup > DSP > FreeDV (RADE), with your callsign and grid square. Nothing about you is sent unless that box is ticked.
