thanks for checking in !? yes credit W7ZOI and others for that nice tool from Elecraft - that is exactly Wes's circuit.? it should provide good power measurements, so like you I am asking him to check his voltage (I recommend key up and key down, but if our 'sdr freak' is not also a CW geek he may not resonate with this wording!).? yes less voltage 'key down' makes less RF power.? Given the high manufacturing quality of the boards, I always assume its my workmanship or use first before blaming the board !? too easy to send the board into surgery without its cause.?
I hope Fabian finds what is going on.? If voltage is okay, I suspect the audio drive could be low - hence my recommendation to measure CW output levels.?

Re: ¡° Farhan's antenna and multifunction analyzer was introduced and sold at Dayton ¡°
Farhan has a very nice video somewhere on the web describing it in great detail - it is more than an antenna analyzer.? It was within an interview type ham radio podcast - I enjoyed it greatly!?
It should benefit experimenters world-wide !? Grab a few key words from HFSignals and I trust you can find the video.? As for review, you will have to wait from one of the early purchasers to relate their experience (its only been a few days since they got it !)

Re: Look at this on eBay, ubitx, budget test equipment.
Hey guys it's Kelly. Took a week off to do some things regarding some python programming, and decided to finally tackle the issue with the receiver not hearing anything. First thing I did was to totally remove the AGC board. I went back and did some digging on ND6T's website. I found some 90 degree header pins and soldered them to the RF path trace that was cut.. I used a flat head screwdriver to GENTLY scrape to the copper traces, this time. Then i placed a (don't laugh) female to female arduino jumper wire on the pins, and powered up the radio. Well, IT WORKS!? Loud and obnoxious as ever...boy i sure have missed my lil ubitx. Oh. My custom field day logbook is ready! (Linux only). Going to enjoy the radio for a spell. See you guys on field day! Look for WA5CC. Cross County ARC.??

Looking at the schematics I would said it could be almost a receiver (apart from the AD part)... Interesting. Up to which frequency could it be possibly used? 23cm?

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'.
