Yes, it is really helpful that after the conversion to FSK a quasi-constant signal level is available.
This made e.g. the alignment and optimization of a receiving antenna much easier.
A second receiving channel a few kHz below the (or above the upper) beacon (requires only a few GNU radio blocks) even allows real SNR measurements.
The proposed level stepping would unfortunately cancel out these advantages.
On the other hand, for the combination of an ancient transceiver and a converter, the proposal could certainly be useful.
So, as a compromise, please keep the lower CW-beacon unchanged and extend the upper one with the level stepping, if really necessary.
