Hi David,
The batteries are not always 'On'.? They are disconnected from the circuit when a) something is plugged into the barrel connector, or b) the switch is in the Off position.? There is no software time-out that I am aware of.? ?You will drain the battery pack if you don't turn the switch to the Off position.
Recheck your batteries.? ?There are six 1.5V batteries in the pack, which should give 6x1.5v = 9V output.? ?6V output sounds too low to me.? ? I measured good voltage at the bottom solder joint on the barrel connector, but the pin was poorly soldered.? ?Resoldering the pin solved my problem.

If power out on CW and SSB are both low then the PA gain is lower than expected or something with filters.

At 20/05/2019, you wrote: Good morning, Curt! Thank you for helping me.
I'm not so well trained in this area yet, I've recently upgraded my class E to class A license, but it's a real project for the first time and I'm not so experienced yet. This is really embarrassing for me and I would like to learn more, but right now I'm a little bit overwhelmed with all this.
Ok, when 8-10W output in CW was fine, i can only say the maximum ever seen was 4-5W in 80m CW on Wattmeter/Dummy Load..
The measurement of the CW power and the 45Mhz signal is such a thing, what am I supposed to do now?
Should I just do a test with a dummy load connected to the antenna socket and then measure on 80m or 40m CW and read the value with the DVM? If so, I did that.
But the one with the 45Mhz signal surely concerns another measurement that is printed, right?
And because of the audio oscillator I found a circuit diagram, but is a simple 2-tone generator with NE555 IC and I would build that, or should I do something else?
If it helps I could make a video of the previous measurements and then upload it with a link, but there would be good to know what exactly you would need to see to help me. I have few kinds of instruments here that are for a beginner, 100Mhz Digital Storage Oscilloscopes, Signal Generator, RCL Meter, AC Millivoltmeter, RC Generator, Lab Power Supply, and many components to build schematics for various projects.
Only the experience is missing.

Raspberries run linux.? You HAVE to use sudo to install anything because that gives you root access.
Type 'sudo apt-get update'
Then follow it with 'sudo apt-get dist-upgrade'.
That puts your OS at the latest patchlevel.
NOW type 'sudo apt-get install java'
That should get your java installed and stop all the error messages,

Please be gentle.
Raspberry Pi 3B, sudo-updated and upgraded, installed Arduino. Noted no icon on desktop: should I have done that non-sudo?
At terminal, git clone from CEC's web-address as instructed. Took a while so I assume it all went according to plan.
Moved directory to ~/src, tried to open file in IDE (from menu), got told it needed to be moved.? That done, tried again.
Here's where the hiccups start: IDE shows blank sketch _may21a, and that doesn't change after (supposedly) loading .ino file.
Verify seems to compile something, exits with error about undefined 'loop'.
HELP!

That's a pretty good explanation, thanks so much.? It explains it exactly what I needed to understand.? Tim highlighting the regulator and looking up the datasheet had me look up the datasheet myself, my first datasheet lookup, so i saw the max input of 35v and a variety of output voltages, 5.0v being one of them.?
It's good to have it explained in such a manner where I can look at the diagram and understand what's going on.?
Thanks so much for taking the time to explain, it's very appreciated,

The switch is a simple ON/OFF switch, enabling power to pass into the circuit from the battery pack / DC barrel jack (since they're wired together).? The battery only works when something is not plugged into the barrel jack.? Battery is the battery pack, and DC J1 is the barrel jack.? The USB powers it without the switch, because it is feeding the voltage directly from the arduino, skipping the power input (battery/jack, switch, polarity protection, voltage regulator) altogether.
I'm going to do my best to explain this, but I usually am pretty bad at teaching.? So...
Power comes in from the PIN on the barrel jack (DC J1, pin 1), and ground is the barrel sleeve (DC J1, pin 2).? Power goes in, through D1, which as a diode allows current to pass in one way only (preventing you from blowing the circuit from powering it in reverse).? This then goes through the On/Off switch (SW1A), which blocks the circuit (off), or allows it to pass (on).? The current goes into U1, a linear power regulator that outputs 5volts.? From here, the current goes off to the various components.
The battery pack is wired in parallel (as opposed to series) with the DC power jack.? If nothing is plugged into the power jack, then voltage flows through D2 to the switch (same as in the case of the power jack), but the main difference here is the battery's ground side.? The negative side of the battery connects to ground (Battery1, pin 1), but does so THROUGH the barrel jack (DCJ1, pin 3).? If nothing is plugged in, pins 2 and 3 are grounded together, and thus the circuit is completed.? If something is IN the barrel jack, then pin 3 is forced away from pin 2 (ground), and thus breaks the circuit from ground, and the current can no longer flow.? This effectively cuts the battery out of the circuit whenever you power it from the DC jack.
Someone smarter than me should be able to explain it much better, but I hope I helped!? I highly recommend Grob's Basic Electronics, as well as Sparkfun electronics' learning pages.

So starting at the Barrel/Battery pack connectors we go through some 1v4148's as Reverse Polarity detection. From there we go to a switch which turns off the Antuino when running on battery or the barrel Jack.
From there it goes into a 5v regulator.
The barrel jack looks to feature a D/C switch for the battery pack when something is plugged into it.
The max input is marked as about 35V according to the LM78L05 data sheet, realistically I'd stay under 12V just for burnout concerns.
I am slowly working through it all my self, Its quite a nice project!
