I run my LA1K up to 3:1 SWR with the HF-AUTO in bypass with no issues.? I have never had it kick out into bypass when using the HF-AUTO.? Most of those that have, discovered either a microsecond arc in a coax connector, or a lightning polyphaser causing the arc.? If there are no issues with your coax between the amp and the antenna, its not going to kick out.
