[Elecraft] KX3 & KXPA100 into Ameritron ALS-600S

[David Ahrendts]

I want to run my just-born KX3 and it’s 100-watt companion KCPA100 into a high power linear, my Ameritron ALS-600S. But we have some issues. For instance: the combo easily produces 600 watts CW. But, on SSB it far too easily trips the Ameritron load fault, or the KXPA100 high SWR shut down. This rather acts like RF feedback. Maybe I just need to follow better RF hygiene here (higher quality coax cables, making sure RF does not loop back on a power cable, etc.). Any collective wisdom appreciated.
