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.

Could TC4428 be keyed in G3YXM design? If so, it would simplify the whole schematic. Petr, 'FIG One option would be to use the TC4428 driver chip. This has one inverting and one non inverting driver.

Dear Andy, LF group, What sort of TX is it? It uses the Decca circuit configuration, together with my existing 60V PSU and modulator. It uses a single PA rather than 3 in parallel, so the circuit is
