Well,? when you key up your radio to get the HF-AUTO to tune, the LA1K sees the SWR is not stable, and goes into SWR lockout.? Then once the HF-AUTO finds an SWR match, the next keyup of the rig will enable the LA1K by itself without having to reset it, or take any action.? They just work great together, but there is no actual connection between them other than the coax.??
IOW, you turn on the LA1K, take it out of standby, and do whatever you want.? If you transmit and the SWR is below about 2.5, the amp works.? If its higher, or there is a spike in SWR, it cuts out for that transmission.
