Thinking CarlBuilt 400HD for AT6666 combo
- Thread starter CB590
- Start date
What’s the plan for now, CB? I think I’d be a bit uncomfortable running HGs at those SWR levels.
Do you think the amplifier is generating harmonics that give the higher reading?

From what I can see thru messenger Carl hasn't been online in like 2 days. As my last messages are not even received yet. So I hope he is well.
Probably stick with SSB with it for now. Or run the 296 with it if I decide to do AM mode. Like you said I don't like the high SWR either. Still waiting on RadioWorldUK t send me my Sirio 2016 missing parts so I can get that up and hope it cuts my SWR issues and high qrm issues too.
I dont know if someone said it yet but you need to put it on a dummy load and then look at the numbers. It will help rule out any variables.
I need to find a nice high load. I currently have none and have to buy car/truck tomorrow as my trucks been in shop a month and I'm done with the shop. After that gets squared and I get funds I will check out getting one. Need a 300w one at the minimum. I know my A99 has had issues when the wattage goes up. Thinking it just sucks with high power.
Use that same peanut oil for deep frying turkey?
You could drop some chicken wings in the can and key the mic a few times. Hold the key down and say “Audio Audio Audio“ numerous times and wings be ready for some hot sauce.

I usually just put them on the exhaust manifold, but it so happens I do prefer fried over baked...!
Well, by meter alone, if you're running Class C, that would be about right - low Dead keys, if you think of it this way, are low volume signals arriving into a stage - the amplifier is just sitting idle - so there's noise in all of that (the THD IMD stuff) - so as you improve the signal transfer into the amplifier, the waves it can generate have less IMD but the THD stuff will always be there.
The Class AB stuff - the better the bias that is there - the better the signal transfer into the amp (I'm referring to the admittance) so as I can see, the AB bias kinda "Washes" out the low-level signal but as you swing power into the amp stages, it gets cleaner because it "sees" a more accurate signal to amplify.
So do you do fish, or poultry?

Carl has been off FB for about 2 weeks. Hope he is ok. Nothing yet. Could just be my A99. Never liked power. Still waiting on my Sirio 2016 parts.
Well, I hope it works out OK in the end.
Do you know if the amp has the HG 2SC2879 C transistors? Or does it have the lower power output HG 2SC2879's? Link below from Carl's website.

appears to not have been on FB messenger since June 5 or so. I've got unseen msg since June 8th.
Hope he is ok. You can always try to call him. His # is in his videos and I think on his page.
- No one is chatting at the moment.
