RST SEAL 3.3.0

This application serves as a CW QSO trainer designed for beginners in Ham Radio communication. It enables users to simulate QSO exchanges by randomly selecting various data fields such as CALL, RST, Name, QTH, Rig/Ant, and Age/WX, thereby providing a practical experience of actual radio contacts.

By default, the operator name is set to "OM." Users can input their own name using the software keyboard. To initiate a session, press the "START" button; for repetition of the previous exchange, use the "AGAIN" button. Adjustments for frequency, transmission speed, and volume can be made using the "VVV" button, which accesses the corresponding controls.

The application includes the following input options:

• CALL: Listen to a callsign and enter it, then press Enter.
• RST: Hear the RST report, enter it, and press Enter.
• NAME: Listen to the operator's name, enter it, and press Enter.
• QTH: Hear the operator's QTH, input it, and press Enter.
• RIG/ANT: Listen to the rig or antenna information, then enter and confirm with Enter.
• AGE/WX: Hear the age or weather information, input, and press Enter.
• QRN: Toggle the background noise suppression.
• Entity: Select the country entity—W/W, JA, or US.
• FuzKey: Enable fuzzy keying, simulating a straight key operation.

Adjustment features include:

• FREQ.: Selects the CW tone frequency.
• SPEED: Sets the CW transmission speed.
• VOL.: Controls the sound volume of CW signals.
