For anybody looking for the link here it is. /g/BITX20/wiki/Raduino-Topics

Mike:
I've already uploaded a file for installing the IDE and libraries. GO to the files section and sort by date, and look for my addition on March 15. If you think it's worthy of adding to the Wiki, feel free to do so.

I've put content into the following WIKI pages:
"Retrieving the Raduino Code"
And
"Retrieving the Si5351A Libraries"
Both are found under "Raduino Topics" on the main WIKI page.
If someone has the time please verify this information and comment.

Re: PA voltage and RF output
As a disclaimer effort, I listed the model number of the watt meter in case of known unreliability. I don't have anything better to compare it with. And I mentioned a 1khz tone into the mic because of steady maximum drive above my voice fluctuations. I can make the meter peak at 24W with voice but it flutters around 10W with conversational speech. 24W max with tone. Around 10W or so while talking. Does that sound better?

Is your code complete, or is it just the fixes? Does it include the correct library?
I looked at it, and I got the sense it was just the fixes, but I really do not know much about this stuff.

Yes that's Ashhar's official master of the BITX40 sketch.
Trouble is that it has some bugs and it's not compatible with the latest
SI5351 library.
As I felt it is important to have a basic sketch that should always work
on a new raduino, I created a "fork" of Ashhar's sketch which corrects
these issues, and I requested Ashhar to merge it with his master. But so
far he didn't have time to do that unfortunately.
Until then, the improved code is available from my Github repository at

Re: PA voltage and RF output
Be careful.
Volts x Amps = power for DC.
For AC it is a bit different. Volts = Pk to Pk/2 x .707.
Efficiency is usually measured as DC power input vs. AC power output.
Fred is right to question the 96% apparent efficiency figure.
Raj is right.; the real figure is more like 40-50%.
If the power meter is correct in proclaiming 24W RF output, the DC power
input is probably more like 50W, or 24v x 2A. By the same figure,
12v x 1A input gives about 5W RF output.
This assumes a 50 ohm system with a near 1:1 SWR.

Re: PCB uBitx -working on it-
Modular boards! ?Brilliant! ?I never build a receiver, transmitter or txcvr all on one board, as I inevitably end up changing parts or stages of the design. ?I always build RF, filters, PA, IF and BFO, and VFO/DDS on separate boards, usually screened and boxed, to provide physical separation, individual debugging and potential rebuilding/replacement, repair, reconfiguration, etc. ?The modular boards are the right approach for an early stage design. ?I'm working on a scratch build of uBitx and will post pictures and descriptions as the modules come alive.

Re: PA voltage and RF output
Reading what has been?covered here in the past, I was not going to power either the fan or the convertor (<>) off the main board. They are going to be powered directly off the 12V input. I have?drawn up the schematics in a way that I will be able to switch to run the PA stage on either 12V or 24V. The fan will have its own switch - probably only run it at when the PA is run at 24V.
This is all being planned whilst?waiting for the boards to be delivered in a couple of weeks. 73 Sasi VK5SN

Re: PA voltage and RF output
It will be more like 2A, when you double the voltage the current will
double and power X4
Efficiency will be more like 50%

If it is 1.25 amp then not 96%.
