Re: V6 radino on V5 board?
I am software but the wiring of the LCD connector is totally
different between V5 and V6.

? You can buy the tft off ali express for about 5 dollars and upgrade the firmware. So the answer is yes, you can update a v5 to have a v6 style display.
No need to swap out the entire Raduino, just the display itself.
Then burn the v6 firmware into the Nano.
I believe the Raduino board has not changed since first introduced for the Bitx40,
except that now a socket is used on the Nano to make it easier to replace.
The old 2x16 display just plugs in, hopefully the new display can plug into
that same old connector?with no soldering necessary.
In the past, it has been possible to buy a Raduino separately from hfsignals for about $30.
I don't see that as an option on hfsignals.com now, the only items to buy are the complete v6 uBitx and the Antuino.
But if the display is easy to swap out, and the Nano is socketed and thus easy to replace if it fails,
that covers most of why you would want a new Raduino.
About the only other stuff on the Raduino is connectors, LM7805 regulator, and the si5351.
If you really do need a new Raduino there have been third parties posting to the forum
offering their own version for sale,?some of them with significant enhancements.

I understand that rick had a problem with a badly crimped connector. It would be impossible for us to test all the individual components. We test the displays, arduinos, all coils and crystals before the board is assembled. After assembly, we set the PLL calibration, the bfo, the pa bias, we test ssb and cw on 80, 40, 20 and 10 meters. The alignment has to be done on the pair of the digital board (raduino) and the analog board (the main board) as the crystals of the IF filter and the crystal of the Si5351 have to be calibrated and aligned with respect to each other too.
I've stumbled across a couple posts from kd8cec about his experiments
with IF offset where he found the si5351 calibration would also
benefit offsetting the first IF (45MHz) as well to compensate for both
what I guess may be a little drift between 45MHz filters but also the
si5351 xtal.
I'm experimenting with it on my v4 ubitx and see that indeed there's a
benefit from offsetting the first IF / VFO frequency too. I'm trying
to nail it down using the kd8cec firmware and then port the minimum
set of changes needed to your v4 firmware.
Have you looked into that as well?

Re: For Sale new uBITX kit with additional uBITX board plus display
Hi Patrick!
We can split the parts between us,? If You take the extra board for $50, and I take the new unbuildt complete kit for $100, we'd have a win-win. Seller ships all of it to You and You then ship to me?? I'll pay You for the shipping US-Sweden, and can send You the $100 up-front.

Hi,
In WA2EBY's original paper he carefully studied the requirements for keeping the IRF510 at a safe temperature:
"The amplifier can also be damaged by overheating.? This limitation is imposed by the TO-220 packages in which Q1 and Q2 are housed. ? The thermal resistance from junction to case is a whopping 3.5¡ãC/W.? This huge value makes it virtually impossible to keep the junction temperature from exceeding the +150¡ãC target for good reliability."
"To keep the transistor junction temperature below +150¡ãC requires preventing the transistor case temperature from exceeding 46.8¡ãC."
"Also, there is a temperature rise across the mica insulator between the transistor case and heat sink of 0.5¡ãC/W.? That makes the maximum allowable heat sink temperature limited to 46.8 ¨C (0.5 ¡Á 29.5) =32¡ãC."
73,
Mark

Edwin -- why did get those exact thermal switches? Because I wanted the fans on, until it got warm, then turn off. And that worked perfectly. hahah.
No, actually, I was a dope and didn't pay enough attention when I purchased them, and then I failed to test'em.? [We don't need no stinking test'en here!!]
So the switch and fan combination worked the exact opposite way I wanted. Perfectly wrong.
On the other hand, they quickly failed. So I guess we are even.
At the risk of further humiliation, would you pass me a link to the correct thermal switch?? I will endeavor to not spectacularly screw up the second go-round.

I see you use NO switches starting from 35 degrees Celsius. In a case that would mean the fans are almost always on. Why did you pick this specific temperature point? I just bought a 50 degrees Celsius to switch a fan in a power supply on. For uBITx it might be somewhere in the 50-60 degrees range I would think. PE3ES/F4VTQ-Erwin ? -- PE3ES - F4VTQ - Erwin 73

Yes, its frustrating that the simplest problems take so long to track down. That was certainly a DOH! moment (slaps head...). It's on me, not you. I often preach 'Look for the simplest problems first', yet I catch myself missing what should be obvious way too often, The incorrect assembly instructions, and the bad jumper itself, were part of the inkits case kit, not the uBitx itself from HFSIGNALS, so again, clearly not your problem. and those have been found and corrected, so moving on... I've been tinkering with this since May, off and on. I've certainly had a lot of fun and education along the way, but I have yet to hear a recognizable voice or copy a single character of code. I've got a beautiful little box that _almost_ works. I just need to get the oscillators somewhere 'in the ballpark' so that I can finish a calibration using the procedure you published. Or might there be another, simpler maybe, reason for zero receive sensitivity? -- Rick Green We, the People of the United States of America, reject the U.S. Supreme Court's Citizens United ruling, and move to amend our Constitution to firmly establish that money is not speech, and that human beings, not corporations, are persons entitled to constitutional rights.

Heat sinks can't touch? what? no body told me that! (haha)
I let them be very friendly with each other...I figured they like to work together.? I decided to bolt direct with no insulator, and take all the risks of shorting to the cabinet case, probes, random wires, and problematic fans,? and the like. The gain is a fraction more efficient energy transfer. (meaning I couldn't find the insulators.) But clearly the cost/benefit ratio is not in my favor.
I'll ry to find them put them in next time I want to get silicon grease all over my fingers. hahaha.
