CW599 ORIGINAL OPERATING WORKFLOWNEW

IC-7760CW Operating Guide

Build a repeatable CW station around the controller and RF deck. Start with the correct key connector, confirm the intended transmit side, and add dual watch, APF and contest memories only after basic keying works.

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 complete station

Confirm the controller/RF-deck connection and antenna. Match Key Type to the device at ELEC-KEY; do not assume a connector on another Icom model is equivalent.

Confirm receive and transmit

Choose CW on the intended band. Check MAIN/SUB and SPLIT before keying; hearing a station on one receiver does not prove you will transmit there.

Set comfortable keying

Use MULTI for KEY SPEED and CW PITCH. With break-in off and the radio in standby, test dots, dashes and side tone.

Prove the return to receive

Start with BKIN after listening for a clear frequency. Test the station at appropriate low power and verify the external equipment returns cleanly to receive.

Add selective listening and memories

Tune first, compare APF widths, then review memory text and serial triggers. Recheck the active side before each split-frequency exchange.

MODEL SETTINGS INDEX

CW settings, paths, and starting points

Search the model-specific CW controls below. Menu labels and ranges are drawn from official documentation; the notes are original CW599 operating guidance.

Keyer

Key Type and ELEC-KEY

Access path: MENU > SET > CW-KEY Set > Key Type
Options or range: Straight / Bug / Paddle
Factory value / operating start: Factory: Paddle

CW599 note: This setting applies to ELEC-KEY on the controller. Use Straight for an external electronic keyer. Confirm the exact connector in the manual and test each element in standby before connecting the rest of the keying chain.

Manual reference: Basic p. 8-3; Advanced p. 2-12

Keyer

KEY SPEED

Access path: CW: MULTI > KEY SPEED
Options or range: 6–48 WPM
Factory value / operating start: CW599: a speed you can send cleanly

CW599 note: Rotate MULTI and listen to the result with break-in off. Increase speed only when your character spacing remains deliberate; this setting does not change an external keyer’s timing.

Manual reference: Basic p. 4-11

Receive

CW PITCH

Access path: CW: MULTI > CW PITCH
Options or range: 300–900 Hz (5 Hz)
Factory value / operating start: Operator choice; not a factory recommendation

CW599 note: Choose a note that remains comfortable through a long session. Compare it with the received signal before tightening a filter; the pitch control does not move the operating frequency.

Manual reference: Basic p. 4-11

Receive

Side Tone Level

Access path: MENU > SET > CW-KEY Set > Side Tone Level
Options or range: 0–100%
Factory value / operating start: Factory: 50%

CW599 note: Adjust sidetone separately from key speed and pitch. Practise only in standby with break-in off, then check the level again when changing headphones.

Manual reference: Basic pp. 4-12, 8-2

Keyer

Paddle Polarity

Access path: MENU > SET > CW-KEY Set > Paddle Polarity
Options or range: Normal / Reverse
Factory value / operating start: Factory: Normal

CW599 note: Reverse the assignment only if the physical sides are opposite to your habit. Test each paddle independently before sending a callsign.

Manual reference: Basic p. 8-3

Keyer

Dot/Dash Ratio

Access path: MENU > SET > CW-KEY Set > Dot/Dash Ratio
Options or range: 1:1:2.8–1:1:4.5 (0.1)
Factory value / operating start: Factory: 1:1:3.0

CW599 note: Keep standard weighting while assessing your spacing. Adjust only after listening to a recording, not to compensate for a poor network connection or inconsistent hand timing.

Manual reference: Basic p. 8-2

Break-in

VOX/BK-IN and delay

Access path: CW: VOX/BK-IN; hold 1 s, rotate MULTI for delay
Options or range: OFF / BKIN / F-BKIN
Factory value / operating start: CW599: begin with BKIN after practice

CW599 note: BKIN waits after key-up; F-BKIN returns to receive between elements. Check the on-screen indication and actual receive recovery. A fast radio does not guarantee that an external amplifier is ready for QSK.

Manual reference: Basic p. 4-12

Break-in

Rise Time

Access path: MENU > SET > CW-KEY Set > Rise Time
Options or range: 2 / 4 / 6 / 8 ms
Factory value / operating start: Factory: 4 ms

CW599 note: Envelope shaping and break-in delay solve different problems. Keep the default shape while proving the amplifier and relay timing; evaluate a change by the transmitted signal.

Manual reference: Basic p. 8-2

Receive

APF

Access path: CW: APF/TPF; hold 1 s for APF menu
Options or range: SOFT: WIDE / MID / NAR; SHARP: 320 / 160 / 80 Hz; 0–6 dB
Factory value / operating start: Factory: SOFT, WIDE, 0 dB

CW599 note: Select the intended receiver and tune the note before applying APF. Compare widths at similar loudness. If the signal seems to disappear, widen the filter or switch APF off and retune.

Manual reference: Basic p. 4-13

Memory / PC

Memory keyer

Access path: MENU > KEYER > EDIT/SET > EDIT
Options or range: M1–M8; 70 characters each
Factory value / operating start: CW599: review before sending

CW599 note: Use your own callsign and review the whole message in standby. A one-second hold repeats a memory; touch the same key again to stop. Confirm the transmit side before calling a split-frequency DX station.

Manual reference: Advanced pp. 2-9–2-10

Memory / PC

Contest serial

Access path: MENU > KEYER > EDIT/SET > 001 SET
Options or range: Number Style; Count Up Trigger; Present Number 001–9999
Factory value / operating start: Factory: Normal; M2/M5; 001

CW599 note: Review the asterisk serial placeholder and the memories that trigger counting. Compare the current number with the log; use the minus-one control if a repeated exchange advanced it accidentally.

Manual reference: Advanced pp. 2-9–2-11

Memory / PC

USB CW keying

Access path: MENU > SET > Connectors > USB SEND/Keying > USB Keying (CW)
Options or range: OFF / USB (A) DTR / USB (A) RTS / USB (B) DTR / USB (B) RTS
Factory value / operating start: Factory: OFF

CW599 note: Match the program’s COM port and control line to the radio setting. Prove computer keying with RF inhibited before enabling the transmit chain; avoid conflicting SEND and keying assignments.

Manual reference: Advanced p. 11-2

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 CW contact

A calm setup for learning the radio.

Keying: Use the hardware mode that matches your key
Break-in: Start conservatively with semi break-in
Receive: Prioritize comfortable pitch and level

Weak signal listening

A patient workflow for signals close to noise.

Filter: Tighten gradually, while preserving your preferred tone
AGC / audio: Avoid changing several receive controls at once
Tuning: Use the radio display only as an aid; copy by ear

Faster exchanges

For operators who need quicker station turnaround.

Break-in: Only increase switching speed after a full station check
Keyer: Confirm paddle direction and weighting before calling
Station: Verify amplifier, relay and interface behavior first

Questions and troubleshooting

Why is there sidetone but no RF?

In standby with break-in off this is expected and useful for practice. Before enabling BKIN, confirm the selected transmit band, antenna, key type and external equipment. Do not compensate by raising power.

Why does the other receiver sound wrong after a change?

Confirm which side is selected before changing a filter or tuning. Dual reception, the main tuning target and the split transmit frequency are separate choices.

What changes when the controller is separated from the RF deck?

The controller and RF deck must maintain their connection. If audio or keying becomes intermittent, stop transmitting and check the link and official setup guidance. Do not treat network delay as a reason to shorten amplifier switching times.
