Questions and answers
Bom dia. Estou tentando configurar YAESU FT 450 para Digimode ( FT 8 e outros) e recepção está normal, porém ao entrar em TX, o rádio pula frequência. Estou conectando o rádio no modo CAT. Tks, 73
To configure the Yaesu FT-450 for Digimode (such as FT8) without frequency jumping during TX when using CAT control, follow these steps:
1. Use "Packet" Mode: Set the transceiver to "Packet" mode, not "RTTY", because "RTTY" mode on the FT-450 is not AFSK-based. "Packet" mode supports AFSK-based digital modes like FT8.
2. Connect via Data Jack: Connect your interface or TNC to the rear DATA jack of the FT-450. Use the correct pins:
- DATA IN (Pin 1)
- DATA OUT (Pin 2)
- GND
3. CAT Control: Ensure CAT control is properly set up to manage frequency and PTT. Use the CAT port (RS-232 or USB if using a converter).
4. Disable VOX or Set Proper PTT: Use CAT or hardware PTT control instead of VOX to avoid unintended frequency changes.
5. Avoid Frequency Shifts: To prevent frequency jumping during TX:
- Ensure the software (e.g., WSJT-X) is not sending CAT commands that change frequency on TX.
- Set the transceiver to "Split Operation = None" in your digimode software settings unless split is required.
- Use "Fake It" or "Rig" split mode only if needed and properly configured.
6. Menu Settings: Adjust menu settings to match your setup, especially audio levels, data mode options, and PTT control method.
This setup ensures stable frequency during digital mode operation using CAT control.
