On the other hand,if you would use one = single=20 linear amp  to TX two 15W carriers (tones in USB)
it would have to be capable = of delivering=20 900W(!) PEP to stay linear.

It wouild appear that if one=20 is txing  WSPR and = OPERA parallel on one
TX,the TX and (a = possible) power=20 amp wouild  have to be linear,
i.e. at least in class AB = ?
