The following feature is updated.

While a CW / Voice message (one-shot) is played back, when pressing and holding down the same message memory cnannel key [CH1], [CH2], [CH3], or [RX/4] temporary repeats the current message.

The function works when Menu No.56 (PLAYBACK REPEAT) is set to "OFF"(Default).

For example, "CP 1111" or "AP 1111" appears on the sub-display while temporary repeating the message in channel 1.

To stop the temporary repeating message, press [CH1], [CH2], [CH3], [RX/4] or [CLR] key.

The same interval time is applied as the value which is set in Menu No.57 (PLAYBACK INTERVAL TIME).

The funciton is not available to activate by a PC command.

The following symptom is revised.

When the meter is set to show "compression" in LSB/USB or FM/AM mode, changing to CW/FSK mode does not indicate ALC automatically.
