Your reported symptoms seem likely to be USB related, not anything Raduino per se.
I've had issues with the USB connector on the Nano clone in my V3.  

How did you have the Raduino's Nano USB attached to the host computer when you reported successful sketch uploads?
Directly to the computer or through the digi board?  If directly to the Nano, did you try this connection path for the CAT control?

If you can successfully upload sketches when attached directly to the computer, try using the same USB cable between the Nano and the digi board.

Rgds,
Gary

I've seen issues with the AVR compiler before. I've also used newer versions of the arduino IDE with VSCode. I don't think I've seen that lint warning, though.

I suspect the tool is confusing itself somehow, especially if a recompile fixes it. While a little annoying, unless you want to figure out and help fix the compiler bug, I'd say just recompile and move on :P

Re: 7805 Regulator on the RADUINO and M5141 Regulator on the nano arduino. #bitx20 #du9gt

Bob Lunsford
 

An old axiom from a friend who worked designing power supply transformers and filter chokes is that if you cannot hold your fingers to the transformer and choke for a count of "thousand-one, thousand-two, thousand-three" without screaming, you used too much iron in the transformer/choke. I wonder if this is also an axiom when the use of heat sinks/radiators... For my radios/devices, I prefer to run them a bit cooler. I cannot see the radio/apparatus getting hot or even a component in it. "Getting away with it" when going hot for a device or element in one of my radios or devices is not the way to live when eventually heat, or even vibration, can eventually come to be a problem, eventually, and can be avoided merely by eliminating such sources of potential problem as time progresses.

Much of this us on the edge of possibilities/probabilities but often the theoretical is located at the portal of what eventually happens.

Question: Is this normal?

 

I notice some slight FMing in received signals and when I got ready to put some extra filter caps on the unit I noticed the heating on the 7805.

Re: Addition of a 5v rail...

Bob Lunsford
 

I put my V6 together a week or so ago and remember the 7805 on the "display unit" had a small heat radiator on it and assumed it was there because of previous comments about the heat built up on the device. Is this the regulator to which you refer? After putting the radio together, I have not removed the cover, assuming all is OK. I seriously hate to go into a working radio, preferring to operate a radio even with my fingers crossed.

So far, the radio has worked marvelously. I hate to think it is operating marginally and is teetering at the edge of the proverbial cliff. I know that some Yaesu 2M radios build up significant heat if operated constantly for several minutes and while this heat surely does not do the radio any good, l have never heard of it being a factor in the radio's failure... Plus, I have not seen any review where the radio has actually failed from said heat...!

I now must keep this in mind just in case the V6 does go sour. If it does, the first thing I will check is to see if the regulator went belly-up and thank goodness it is in a position to be checked easily.

Is that what prompted you to change rails?

Also, the M5141 regulator on the Aurduino Nano is fed from 5 volts.  Did you change that to the new 5 volt rail?

My unit has some slight FMing, have you noticed that?  I assume it is from regulator problems (above mentioned).

George,

Clamp on a piece of metal or a small heat sink on it. Solves the problem.

Thanks for your feedback.  It may have been that RF got in there in the first place and scrambled something in the raduino? Maybe an Eprom? I had an antenna issue for a bit my doublet was touching a tree after a storm. It was tuned by my autotuner but it had to be very unbalanced. But now you can't even get it to configure wsjtx to talk to the radio.  It reports an error around reading vfo freq before you can ever transmit.

It does work with old raduino and green 2 line display.  The pcb will.be plugged leaving 2 pinsextra prodided for glcd. This what i read at the first version of v6

Re: Thinking about buying a V6 but I have questions.

AndyH
 

Hi Bill,

I have had a V3 for a few years and have enjoyed modding it.  Balancing output power, installing a pop fix, and other things.  I've had a new V6.2 on the air just under a month and it's a much better radio out of the box than my nodded V3.

The pop fix is incorporated into the board. TX/RX transitions are silent on a speaker. I haven't used phones yet. 

I have a couple of the original AGC boards.  I've recently received one of the kits projects versions with an S meter output but haven't installed it yet.
https://shop.kit-projects.com/index.php?route=product/product&product_id=101

Check with W0EB at the Triumvirate Skonk Worx. They have a Teensy 4.0 hardware upgrade and their own code for the Raduino. One of the upgrades is a a new paddle interface that comes directly off the Teensy that's supposed to be very crisp. I'm using their upgraded Raduino but haven't used paddles yet. W0eb.com

1.  I am a CW op.  There evidently is an issue with latency on CW which would be a deal killer for me.  I see some posts suggesting that there is firmware out there that addresses and solves the problem.  I want to hear from CW OPS with a V6 - is that true for sure?
2.  I ordered and built an AGC kit for my V4 that worked well but can't remember who I got it from - is it still available?
3.  Is the audio "pop" upon TX no longer an issue?
4.  Is the rig readily available in these Covid times?

Thanks in advance!

Re: Segmentation Fault

Jerry Gaffke
 

Mark,

Very weird that GCC reports a segmentation fault, but only sometimes.
My best guess would be memory errors in the host computer.
Any chance you could try this on a different computer?

For somebody keen to hack hardware, a suitable host might be a Raspberry Pi 4.
Quite cheap if you already have a keyboard, mouse, and your TV has an HDMI port.

Or perhaps a borrowed laptop.

Segmentation Fault

Mark Erbaugh
 

I hope this question is appropriate here, since this is a problem when compiling my uBITx code.

I'm using VSCode to do my Arduino coding. It took some setting up, but it is working well most of the time. Every once in a while, when I make a change to the code and compile it, GCC is reporting a segmentation fault. If I exit and restart VSCode, the next compile goes fine.

I don't know whether this is related or not, but every time I open an Arduino project workspace, VSCode displays an error popup:
Conflicted extensions with IntelliSense service were detected (Arduino). Code-completion, linting and navigation will not work properly. Please disable or uninstall them (Menu > View > Extensions).

I ignore this and (other than the occasional segmentation fault), everything still seems to work.

Versions:
VSCode: 1.48.2
PlatformIO Extension: 2.10
Arduino Extension: 0.3.2

Arduino: 1.8.9

I know there are newer versions of Arduino available, but there the serial monitor in VSCode doesn't work with them.

Any ideas, 73,
Mark

Gary,

Why would this be a Raduino problem?  The above statement says it works fine as an SSB radio.  To me, that statement says that the Si5351 and the rest of the board are working.  I would suspect the Nano on the Raduino board, which is readily available on eBay and Amazon.  The USB connection could have failed, which is needed for the CAT control part of the WSJT-X control.

I would order a new Nano, download the .hex file and see if that works.  At most, you will be out $10 for the Nano (That is a high number, they are available for around $4).

BTW, Nice setup for the uBITX!

Disconnecting the red wire works perfectly. Have used it that way since day one.

Amazon's house brand USB hubs have power switches for each USB port. That's another option.
