All my meters swing forward, receiver swings backwards

I've seen that when modulation goes past 100%...like 110% or so. Your meter is seeing the watts....they're seeing a drop in swing because the modulation is over saturated....I think I said that right....?
 
Ok i got it. I will just back the carrier down to 300w-400w and be content. So then whats the max pep into the 16 pill? Everyone i see uses a 4 pill driver
On the HGs, the DK is the only real killer, you need the 25 watt per output transistor rule. You can drive them normally, you just can't hit them with volts or a high DK. PEP is the same as Toshibas....as long as you swing it in.
 
Gotta be nice to the hg pill at least for now. Hopefully their tech continues to advance but until then unless you want to replace transistors id keep the carrier into the 16 to 300 or less. Give it what it likes not what you like is what ive learned.
Everyone is using the regular hg 2879 and thats why i went with the C series.
Seriously though dollar for dollar one or two russian toobs is the way to go any more. That's my next venture.
Russian tubes like the GS-35B are cheap because after 40 years sitting on the shelf, they have lost enough of their vacuum to no longer be considered reliable. After much time wasted with many different Russian surplus tubes, the end result was you were lucky to get them to still run at rated voltage and output for the band they were intended to be used on. That means don't think you can push them harder on HF like a tube that is still under hard vacuum.

This is the reason you must "condition" them first because they are already contaminated inside. I ordered 6 to get 3 good ones after conditioning. One had lost so much vacuum, the filament couldn't even light and showed a dead short that would just heat the base of the tube. Four more failed within a year due to internal arcing. The only one still working 6 years later, is the GS-35B that replaced a pair of GI-7B's and only has about 2kv on the plate.

What are they driving the 4 pill with?
My 4 pill driven with a mosfet mod 29 at 35 watts pep in does about 400 watts pep out on my birds.

Heres another weird thing to me. One guy that was receiving me said when he turned his rf gain down then it had good forward swing on his end, huh? He was like 40mi away so we were not close at all.

The AGC circuits in many radios will invert the direction of swing as the increase in signal strength on word peaks, causes the receiver to automatically reduce gain. While this is unusual at 40 miles, the fact he can turn the RF gain down an see forward swing, reveals your transmitter is swinging forward.

So what is the maximum pep you want to push into a 16 pill hg box?

400 is the "ideal" max... it's HGs though so it could be a tad more....or a tad less. They're kinda like women....some like it rough, some like it gentle, you have to figure out which you have, she'll let you know when you've went too far.

Haha, ok. And whats the pep on a 16? I have always seen and heard 3200w.

Depends on a few things..... How many volts are you running? What the radio is putting out, what size transformers are used in the amp, are the transistors matched, what's the Hfe of the transistors, the input and output tuning....
*edit*
and if you have the current to supply it.

Hmm, ok. All i can answer on that is 14.8vdc with zero drop at 800 amps. Transistors are matched. Amp tuning is superb
