# 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.
