CW599 ORIGINAL OPERATING WORKFLOW
FTDX101D/MPCW Operating Guide
FTDX101D and FTDX101MP share this CW operating interface. Their power configurations and fitted receiver options differ. Use this guide to establish a keying baseline, identify the receiver being adjusted and control received-text decoding.
FTDX101D/MPCW operating workflow

A five-step CW setup routine
Use this order as an operating checklist, not as a replacement for the radio manual. Controls and available options can vary by firmware and region.
Check the test setup
Keep BK-IN off; use MONI to check the paddle.
Set rhythm and tone
Set MIC/SPEED and a comfortable monitor level.
Tune one signal
Choose MAIN/SUB, tune first, then try WIDTH/APF and DECODE.
Send and listen
Verify the transmit VFO and power before enabling BK-IN.
RECEIVE ASSISTANCE
CW decoding: enable, tune and recover
FTDX101 uses the received speed setting and a decode threshold. Set both for the station you are listening to; decoded text still needs ear confirmation.
Select CW and match speed
Turn MIC/SPEED close to the incoming CW speed.
Open DECODE
Press FUNC and touch DECODE.
Tune and set DEC LVL
Center the wanted note. Touch DEC LVL and adjust MULTI if idle noise makes text.
Read or stop
Compare TFT text to the signal; DEC OFF stops decoding.
When decoding needs help
No text
Return to the receive-decode setting above, confirm a steady audible CW signal and retune before changing more parameters. Transmit echo alone does not confirm receive decoding.
Garbled text
Listen to one complete call and compare it with the display. Fading and irregular spacing can defeat the decoder; request a repeat and copy by ear instead of completing an uncertain callsign from guesses.
Another station takes over
Center the wanted signal first, then narrow the receive filter gradually. If the wanted tone disappears, widen the filter and tune again. Stop adjusting when a clear tone and stable text agree.
MODEL SETTINGS INDEX
CW settings, paths, and starting points
Search by setting or menu path. Manufacturer defaults and recommendations are labeled separately from CW599 advice; references identify the checked manual or software version.
Keyer
Configure front and rear keys separately
- Access path
FUNC > CW SETTING > KEYER > F/R KEYER TYPE- Options or range
- OFF / BUG / ELEKEY-A / ELEKEY-B / ELEKEY-Y / ACS
- Factory value / operating start
- CW599: change only after the listening or keying check below.
CW599 note: Choose the row for the socket actually used. OFF accepts direct keying; use an electronic-keyer mode for a paddle. Keep BK-IN off while confirming independent dots and dashes.
Manual reference: FTDX101MP/D Operation Manual 2406R-US-1, pp. 58–62, 97–98
Keyer
Set speed for sending and decoding
- Access path
MIC/SPEED- Options or range
- 4–60 WPM
- Factory value / operating start
- CW599: change only after the listening or keying check below.
CW599 note: Press MIC/SPEED to enable the internal keyer and rotate to adjust speed. For receive decoding, match the received speed closely; a comfortable transmit speed can be different from a fast caller’s speed.
Manual reference: FTDX101MP/D Operation Manual 2406R-US-1, pp. 58–62, 97–98
Receive
Practice with BK-IN off
- Access path
BK-IN off; MONI; hold MONI > MULTI- Options or range
- Monitor enable and level
- Factory value / operating start
- CW599: change only after the listening or keying check below.
CW599 note: Enable the monitor and set a modest level while keying without RF. Verify the BK-IN indicator is off; a monitor tone by itself says nothing about whether RF is being radiated.
Manual reference: FTDX101MP/D Operation Manual 2406R-US-1, pp. 58–62, 97–98
Break-in
Choose semi or full break-in deliberately
- Access path
FUNC > CW SETTING > MODE CW > CW BK-IN TYPE / CW BK-IN DELAY- Options or range
- SEMI / FULL; delay 30–3000 ms
- Factory value / operating start
- Manual defaults: SEMI, 200 ms.
CW599 note: Begin with SEMI and listen to the recovery after a short word. Change to FULL only after the amplifier and switching chain are checked; longer delay may sound calmer for ordinary QSOs.
Manual reference: FTDX101MP/D Operation Manual 2406R-US-1, pp. 58–62, 97–98
Keyer
Keep the normal dash ratio first
- Access path
FUNC > CW SETTING > KEYER > CW WEIGHT- Options or range
- 2.5–4.5
- Factory value / operating start
- Manual default: 3.0.
CW599 note: Use the standard ratio while checking your paddle timing. If an exchange sounds crowded, fix missing character gaps first; changing weight cannot create space between letters you run together.
Manual reference: FTDX101MP/D Operation Manual 2406R-US-1, pp. 58–62, 97–98
Receive
Use WIDTH and APF on the intended receiver
- Access path
MAIN/SUB selection > WIDTH / APF / CONT/APF- Options or range
- Passband width and audio peak center
- Factory value / operating start
- CW599: change only after the listening or keying check below.
CW599 note: Tune the desired signal first and confirm which receiver is being adjusted. Narrow WIDTH, then compare APF on/off; return the peak toward center if the wanted note becomes quieter.
Receive
Open received CW text
- Access path
CW > FUNC > DECODE- Options or range
- Received text; DEC LVL; DEC OFF
- Factory value / operating start
- CW599: change only after the listening or keying check below.
CW599 note: Match MIC/SPEED to the incoming CW and read the TFT text. If idle noise produces characters, open DEC LVL and adjust MULTI. Use DEC OFF to stop the decoder when you prefer listening alone.
Memory / PC
Record MESSAGE or enter TEXT
- Access path
FUNC > REC/PLAY; KEYER > CW MEMORY 1–5- Options or range
- Five memories; MESSAGE paddle entry or TEXT entry
- Factory value / operating start
- CW599: change only after the listening or keying check below.
CW599 note: Choose the intended memory method before recording. For paddle entry use MEM and the target slot, then MEM to finish. Play with BK-IN off first and press the same playback key to stop.
Manual reference: FTDX101MP/D Operation Manual 2406R-US-1, pp. 58–62, 97–98
Memory / PC
Configure the PC keying source explicitly
- Access path
FUNC > CW SETTING > MODE CW > PC KEYING- Options or range
- OFF / DAKY / RTS / DTR
- Factory value / operating start
- Manual default: OFF.
CW599 note: Select the line used by your interface or logging software, then test with RF disabled. Do not infer correct keying from a working CAT frequency display; these are separate controls.
No matching settings. Try a shorter search or clear the search and category.
CW599 RECOMMENDATIONS
Three operating starting points
These are original operator-oriented starting points. They are not factory presets and intentionally avoid claiming model-specific default values.
First contact
Check one change at a time.
- Keying: Match the actual key and verify clean spacing
- Transmit: Check the documented RF-off or dummy-load setup first
- Receive: Use a comfortable tone and moderate volume
Difficult reception
Keep the wanted signal audible.
- Tuning: Center the wanted note before narrowing
- Filter: Compare changes at a similar audio level
- Copying: Ask for a repeat when a callsign remains uncertain
Repeated calls
Leave a clear path back to receiving.
- Sending: Verify any supported message and its stop action
- Listening: Leave time for an answer
- Station: Confirm frequency, power and transmit recovery
Questions and troubleshooting
Does it have CW receive decoding?
Yes. Select CW, match MIC/SPEED to the caller and open FUNC > DECODE.
Why does changing my keyer speed affect text?
The decode instructions require the speed setting to be close to the received signal. Retune and match speed before raising DEC LVL.
Why does a filter change affect the other receiver?
Check MAIN/SUB selection before changing WIDTH or APF; the receivers have independent adjustments.
