I show below some ideas,
1. I want to save beacon messages separately in CW and QRSS/DFCW.
In many cases, the number of letters is from only 3 to 6 in the QRSS/DFCW beacon (a call sign or the contracted form).
2. The beacon messages of QRSS/DECW and WSPR want to program it without a PC.
Particularly, it is convenience that QRSS/DFCW and WSPR program with front panel buttons of TX136/500 because there is little number of the letters. For example, I program it with buttons of FREQ+, FREQ-, RF PWR and OPER when a call sign, a grid and power are displayed in the WSPR page of the CONFIG mode.
3. When there is a change with CONFIG mode, it is desirable that a state is stored promptly when I close CONFIG mode.
Portable use of LF is active in Japan, and the save of CONFIG is effective because, in that case, a power supply may be cut out without intending.
