The blinking rate you perceive is due to the gating applied to the SC preset.
As long as the gating is not changed when you use different frequencies, the blinking rate won't change. That is the normal behaviour.
On the other side, when you use remote mode without gating applied, what you see is the actual freqs being delivered, and thus, the blinking rate could be observed to change as the freqs vary.
