Shift, Tone, Decode. A 64-bit Windows digimode console for a TCI radio.
Sending Transmittal Disease
The real expansion is Shift, Tone, Decode. Around the shack it also answers to Sending Transmittal Disease, because this build is still in the contagious stage. It keys on the bench, it has not finished making the rounds, and the recommended treatment is another shot of bourbon while the modes get proved on the air.
STD: Help keep the infections spreading and buy us a shot of bourbon.

Caught on the bench
20 m FT8 on receive, the same session on the air, and a Feld Hell test that actually looks like letters.
What it sends
TX sends these when you press TX or Tune. Opening the radio does not key.
📡 FT8, FT4, FT2
15 s, 7.5 s, and 3.75 s. DIGU. The MSHV generator. Contest lines Tx1–Tx6 are messages, not extra modes.
🖋️ Hell
Feld, Slow, X5, X9, FSK, FSK-105, and Hell 80, each at its Fldigi column rate. Feld Hell is 17.5 columns/s, 14 pixels, a 2 ms raised cosine. Hell notes.
⌨️ RTTY
One menu row. 45.45 baud, 170 Hz, mark high, 5 bits, 1.5 stop. A space sends LTRS, then the space.
〰️ BPSK and QPSK
PSK31 through 1000. A zero reverses the phase. QPSK31 through QPSK500 use a K=5 code. 8PSK is not in this build.
🎼 Olivia and Contestia
4/250, 8/250, 8/500, 16/500, 16/1000, and 32/1000. Gray-coded tones.
🎚️ MFSK, DominoEX, Thor
MFSK4 through 128, plus 64L and 128L. DominoEX Micro and 4–22, FEC off. Thor 4–22 are K=7. Thor 25x4, 50x1, 50x2, and 100 are K=15.
🌊 MT63
500, 1000, and 2000 Hz, short and long. Sixty-four carriers and a Walsh code. TX sends it, and a character comes back out of the audio.
📻 JS8
JS8Call-improved Normal. 15 s, 50 Hz, on the cursor. The transmit box is the payload. Fast, Turbo, Slow, and Ultra are not in this build.
🌐 WSPR
WSPR-2 from WSJT-X and JTDX. Even UTC minutes. Tx power, Tx Pct, and band hopping. The locator is the one in Options → User.
🗺️ PSK Reporter
In this build. The map uses the callsign already saved under Options → User. Upload after a decode stays off until Enable is checked. There is no second callsign. It does not send START.
📝 Macros
Supports importing Fldigi custom macros. Macro notes.
Receive only
🗞️ WEFAX-576
IOC 576, 120 lines per minute. Black is 400 Hz below the cursor and white is 400 Hz above it. It does not key, and it does not send START.
Still spreading
Not on the Mode menu. They do not key. The outbreak is incomplete on purpose.
✳️ 8PSK
A different constellation from QPSK. Not on the menu, and not keying.
📋 FLD-88
On the list. Not in the menu, and not keying.
Companion apps
Same shack, same developer. STD is the digimode console. The other two already have their own waiting rooms.
🎛️ Lyra
The transceiver. Protocol 1 and Protocol 2, the panadapter, and the CW that stays over there. STD does not send CW.
