I was talking to a guy for about 5 minutes yesterday, and my radio was set on LSB at 12Watts into my KL-500 on stage 2 or 3, but after our 73's I noticed the amp was set to AM, not SSB. I was still peaking at 200 Watts output on my meter, and there was no damage that I could tell? everthing seems normal. So what happens when we put SSB into the amp circuit for the AM band? Was I lucky I was only using the 12 Watts? |

The only difference between the two settings is the SSB position inserts a slight delay before unkeying the amp. No harm in running SSB in AM setting, or vice versa. Mine is set to SSB all the time, but I run some AM and some SSB, no bother. |

Nothing Jim, you should be fine. SSB in the amp works the necessary delay for effective talking on sideband instead of unkeying between words. When on AM, it may have unkeyed during a delay in your conversation but picked right back up when you modulated again.
Being the 12 watts was SSB and not a 12 watt carrier signal, you should be just fine without causing any damage to the amp whatsoever.

The circuit that Highlander is refering to enables the relays to stay keyed a bit longer so they do not open and close with each spoken syllable and make you sound choppy.
You obviously have enough background noise that your mic is hearing and is keeping the relay keyed.
As he suggested, leave the switch in the SSB position and forget it.

That was a good one Jim. LOL.
So that's what it's called when they talk nonstop? And all this time I thought Background Noise only pertained to radio.
Go ahead and tell her that but only if it's true.
You made my day Jim. LOL. I wont be forgetting that one.
