Audio and Keyers
CW keyer
A CW keyer with macros on F-keys (F1–F9; empty slots are hidden). The keyer engine is selectable (Settings → CW Keyer):
- WinKeyer — K1EL WK1/2/3 over a COM port. The log names the generation detected, and a byte-level trace can be enabled for bug reports.
- Serial port (DTR=CW / RTS=PTT) — OpsLog keys CW by toggling a serial
control line itself, the hardware method N1MM/WSJT-X use with a Yaesu SCU-17
or a generic keying interface. No WinKeyer needed. Choose the COM port, which
line carries CW, and Invert keying for interfaces that key backwards. This
is also the engine for an FTDX10 (whose CAT refuses
KY), on the rig's second COM port. - Icom — the radio's own keyer over CI-V, no extra hardware. Works over the remote link too. (Set break-in to SEMI/FULL or the rig keys the sidetone but stays in RX.)
- FlexRadio (CWX) — keys CW straight over the SmartSDR connection, with type-ahead and mid-send backspace.
- Yaesu (rig keyer) — the radio's internal keyer over CAT (
KY), for the FTDX101 / FT-991A / FT-710 family. See Yaesu. - TCI — for TCI backends.
ESC stops CW on whichever engine is active; typing a callsign aborts a
running macro. <LOGQSO> inside a macro logs the contact at that exact point.
Auto-call repeats a CQ with the gap you set measured after the message.
ESM — Enter Sends Message
N1MM-style, for CW (Settings → CW Keyer). With the keyer on, Enter fires a
macro by QSO stage instead of logging: empty callsign → F1 (CQ); callsign
entered → F2 (report), focus jumps to RST; Enter in RST → F3 (TU), which logs
if the macro contains <LOGQSO>.
Digital Voice Keyer (DVK)
Record F1–F6 voice messages and transmit them. Set the audio devices, PTT method and gains in Settings → Audio.
- PTT method: CAT (whichever backend is active — every one supports PTT), RTS, DTR, or none (VOX).
- Auto CQ repeats a CQ-labelled message on a timer until you stop it.
- The DVK refuses to transmit on non-phone modes — no speech on FT8.
- A message level control (Settings → Audio) drives the rig at the right level even from a quietly recorded microphone. If the rig transmits almost nothing, check its rear-input setting (on an FTDX10: SSB MOD SOURCE = REAR).
QSO audio recording
Continuous rolling capture. On Log QSO the contact is saved to a per-QSO
WAV/MP3 (CALL_YYYYMMDD_HHMMSS), with pre-roll. With automatic recording off, a
red dot beside the callsign records the contact by hand.
A recording can be replayed on the air to the station being worked, like a voice-keyer message — with its own level, separate from the voice keyer (a receiver line-out needs far less gain than a microphone). The play button becomes a stop button while it transmits. Hidden on CW.
CW decoder (RX audio → text)
Tools → CW decoder (or the ear button) decodes received CW while the mode is CW: adaptive envelope with noise squelch, per-character dit/dah classification, follows 12–40 WPM and sloppy fists, rides QSB. Shows WPM / pitch / level, locks onto the FlexRadio CW pitch automatically, and clicking a decoded word fills the callsign. Clean-to-moderate signals decode solidly; weak-signal pileups remain CW Skimmer territory.
RX audio monitor (USB rigs)
Settings → Audio → Listen to radio pipes the rig's received audio (its "USB Audio CODEC" input) through your speakers — the level applies live as you drag it. Talk to radio keys PTT and pipes your mic to the rig's audio input.
