Could TC4428 be keyed in G3YXM design? If so, it would simplify the whole

Petr, 'FIG
Petr,

That idea crossed my mind 2 years ago when building my TX (variation on the
YXM design). But due to different delay times in the inverting and
non-inverting drivers (I measured abt. 25ns difference) I didn't use the
4428 it.
If you don't wan't to use a flip-flop to get the counter-phase signals you
can use a couple of CMOS XOR gates, with a CD4077 running on 15V I measured
less than 3ns difference between the inverting and non inverting gate.
