Al,
When I saw your comment earlier today about your LA-1K "kicking out into BYPASS for some unknown reason" I responded in my post
/g/la1k/message/1250 writing in part "My experience doing SSB voice is that the amp’s protection schemes could be unnecessarily set on the conservative side."
I have two (2) homebrew monoband verticle dipole antennas (one 20M, the other 40M) connected by way of an antenna switch to my Ameritron ALS-600S bought brand new in 2016 to pair it with my brand new IC-7300 bought sight unseen from Gigaparts when the Icom first hit the street.? When operating SSB voice on both 20M and 40M with that configuration for years, driven the amp with 60+ watts at time, there were absolutely zero issue with the ALS-600 kicking out into bypass, as long as the human operator (me) remembered to manually switch to the correct antenna.? The ALS-600 can take it like a man!
However, operating with the same monobanders (driven by my FTDX101D at even 40W) the LA-1K has let me down TNTC (too numerous to count) in the middle of a SSB voice transmission going into BYPASS for one reason or another.? Human not at fault with the LA-1K amp's automatic antenna switching.? I believe the LA-1K protection circuitry is way too conservative, and needs to be optimized to match the performance of my dirt cheap Ameritron ALS-600S.
