About 600 Watts, and judging by the (cold) heatsink temp with a small fan
could be be tempted to try increasing power to destruction - under
controlled conditions of course !

This PA does not lend itself to power reduction, apart from switching
transformer taps - but we could try with the original (linear) design some
time.

Is anyone else transmitting this mode yet ?

resolution is best. Looks

like a string of beads of different sizes, i.e. the carrier splits into two
about 10 Hz apart for a short duration and then comes back together.
Fascinating to watch.
What power are you using? It would be interesting to see how sync is
maintained if you step the power progressively lower.
