CW and Band GPIO Settings

Use these sections for QRSS, FSKCW, and DFCW message construction, timing, frequency, fades, scheduling, and per-band switching outputs. For browser configuration, see Configure CW Modes. Related references include CW Mode Options, Configuration Troubleshooting, and Configure Raspberry Pi I/O.

CW

The [CW] section preserves one shared dot duration, the separate QRSS/FSKCW and DFCW spacing triplets, frequency-shift behavior, fade controls, and scheduled repeat values. Numeric-looking content such as 73 remains a text message.

[CW]
; Message:
; Text transmitted by QRSS, FSKCW, or DFCW when the selected mode is non-WSPR.
; Numeric-looking text such as 73 remains a text message.
Message = 73

; Base Frequency:
; Base RF frequency for non-WSPR modes.
; Use whole-number Hz, or add Hz, kHz, MHz, or GHz to decimal values.
; QRSS transmits on this frequency.
; FSKCW uses this as the space frequency.
; DFCW uses this as the dot frequency.
Base Frequency = 14096900

; Shift Hz:
; Frequency shift in Hz for keyed dual-frequency CW modes.
; FSKCW mark frequency = Base Frequency + Shift Hz.
; DFCW dash frequency = Base Frequency + Shift Hz.
; QRSS ignores this field.
Shift Hz = 5

; Dot Seconds:
; Dot length in seconds for QRSS, FSKCW, and DFCW timing.
Dot Seconds = 3.0

; Intra Element Gap:
; QRSS/FSKCW gap between dots and dashes, expressed as a multiple of Dot Seconds.
Intra Element Gap = 1.0

; Inter Character Gap:
; QRSS/FSKCW gap between characters, expressed as a multiple of Dot Seconds.
Inter Character Gap = 3.0

; Inter Word Gap:
; QRSS/FSKCW gap between words, expressed as a multiple of Dot Seconds.
Inter Word Gap = 7.0

; DFCW Intra Element Gap:
; DFCW gap between equal-duration dot/dash symbols, expressed as a multiple of Dot Seconds.
; DFCW dot and dash symbols have the same duration and differ by frequency.
DFCW Intra Element Gap = 0.333333

; DFCW Inter Character Gap:
; DFCW gap between characters, expressed as a multiple of Dot Seconds.
DFCW Inter Character Gap = 1.0

; DFCW Inter Word Gap:
; DFCW gap between words, expressed as a multiple of Dot Seconds.
DFCW Inter Word Gap = 3.0

; Fade Shape:
; Envelope fade shape for QRSS, FSKCW, and DFCW events.
; Valid values: none, linear, raised_cosine.
Fade Shape = raised_cosine

; Fade In Ms:
; RF envelope fade-in duration in milliseconds.
Fade In Ms = 20

; Fade Out Ms:
; RF envelope fade-out duration in milliseconds.
Fade Out Ms = 20

; Fade Slice Ms:
; Advanced envelope approximation control for QRSS, FSKCW, and DFCW fades.
; Smaller values produce smoother duty-gated fades at higher switching cost.
; This does not change Fade In Ms or Fade Out Ms duration.
Fade Slice Ms = 2

; Start Minute:
; Minute after the top of the hour for scheduled QRSS/FSKCW/DFCW launches.
; Valid range: 0 to 59.
Start Minute = 0

; Repeat Minutes:
; Repeat interval in minutes for scheduled QRSS/FSKCW/DFCW launches.
; Must be greater than 0.
Repeat Minutes = 10

Band GPIO

The [Band GPIO] section assigns optional BCM GPIO outputs and polarity independently for every listed band. A blank band assignment disables switching for that band.

[Band GPIO]
; Per-band GPIO assignment for band switching (BCM numbering).
; Assign a GPIO number to enable switching for that band.
; Leave blank to disable switching for that band.
; The same GPIO may be assigned to multiple bands.
; "<band> Active High" controls polarity (default = false).
