Re: Newbie instructions for loading software in Raduino #firmware

Ralph Mowery
 

The Raduino is a combination of two things.  The chip and circuit that generates the frequencies, and a Arduino Nano.  You can unpower the uBITX and plug the mini USB plug into the Arduino nano unit on the Raduino board to power it up and program it.  In other words, forget about it being a Raduino board and just think of it as the Arduino.  Look around on Youtube for lots of info on programming the Arduino nano.

I actually blew the nano board on my ubitx and replaced the nano board with one of them off ebay that sells for about $ 3.  You can get one of those and play with the software so you will not mess up the one in the ubitx.  I have just gotten into playing with the Arduino in the last 6 months or so.  

The kd8cec program and his memory manager is very nice.   I modified mine to use the 6 push buttons to make it more convenient to operate.

Is the Raduino the same as the Arduino so I can use the help recourses available for that platform?
Where can I find help for dummies showing step by step where exactly what to do without assuming one knows the fist steps?

I haven't had a chance transmit other than CW mode into a dummy load. I want to finish my antenna analyzer before I start pumping rf into my Carolina Windom. Reception was very good but noisy with all the weather here in Florida at this time. Lightning is a major concern as my antenna is almost as high as my natural lightning rods, pine trees 60 - 90 feet tall. As a QCWA member I enjoy CW as my primary mode but really have enjoyed WSPR with my U3S. I see alot of digital in my future.

Onderwerp: Re: [BITX20] Using IRF530 outputs and 2N3553 drivers in ubitx

 

I have used the Minipa 70 in my scratch built BitX. While I can get 70 Watts out (13.8v supply), it is short lived as a final will blow within a few seconds and short closed. 50 Watts will work for short QSOs, but taking for more than four or five seconds will destroy the IRF530s. My heat sink is 6”x4” with 2” fins, so I don’t think heat dissipation is the issue. 25 Watts gives me no issues, however.

The uBITx has been a blast!  330 FT8 QSOs in 6 weeks including 46 states and 12 countries on 4 watts or less.  Using end-fed 59 ft antenna to tree.  Having too much fun to see the negative......:) Looking forward to "souping up" the 2nd uBITx!

Re: Why I bought a uBITX

Roxi,

I totally agree with u. some members spout a plethora of knowledge but won't respond to any ham asking for help. but shame on any of us who love to build mention the bickering about who's software is the best what standards etc. Thats why some clubs shut the doors because of internal bickering and everyone has to do it their way.im a builder and a qrper. i bought this rig for the economics of an all band rig and possibly modify it MY way later with the help of other great knowledgeble hams on this forum. I mean really, price of other rigs, and they are outrageous.

Farhan has an incredible rig. unfortunately some hams aren't happy with anything.ive been a ham since early 80s, and i love cw. some do not. some refuse to be my friend anymore because i love cw. oh well, its a great hobby. and a lot of hams forget that. i don't get impressed by the bickering and arguing. its boring and stifles amateur radio as a whole.i was lucky to have mentors who really enjoyed ham radio and was OPEN i repeat OPEN to others suggestions without arguing.i love the forum and the knowledge others bring to share or help ,but i erase any posts that have a bickering title to it.they forget there are thousands of hams who have gone it alone because of bickering ,only to discover a new technology.there are also thousands of hams who are programmers and they don't get on here to argue about code. life is too short to bicker about petty things. Well roxi i probably made some mad but, they will get over it. if not they don't need to be in this hobby. remember we love this hobby to promote technology , self learning and spread goodwill across the world without any biases or politician agendas… 

thats why i mostly work cw. try arguing in cw .:)

I have always said folks need to be more appreciative of what they are
getting here and less ready to bicker/moan about stuff.
Its an awesome little radio and provides freedom for those who want it

This group of folks is awesome and will help with any issues so is
pretty much the best of both worlds.

Re: share your BITX success stories

Rob Snow
 

I've given my report before, but I'll throw it in here for giggles.

My uBITX is my first HF rig.  I ordered to close the deal on getting my Extra.  I got my Extra 2 weeks later and got my CW up to 13wpm (5 char, random) as penance for not getting my ticket 30 years ago.

While waiting for my uBITX to arrived I read every...single...post, looked up part numbers, googled what it did when I didn't understand it, ordered some extras, practiced my soldering and read some more.  I ordered the SMD practice boards, a new soldering iron and some spare IRF510's and RD16's as well as some SMD kits.

uBITX arrived, I soldered it up and started the "Junkyard Dogs" thread here for my complete lack of regard for aesthetics.  I fired it up and couldn't get any SSB QSO's with my EFHW, so I found the CW key memory and sent "TEST AG5OV TEST" a few times and checked the RBNs....IT LIVED, I was getting out!

Next I updated the firmware to Ian's fantastic work and soldered up a home grown EasyDigi interface and plugged it into a RPi.  I've been running FT8 and WSPR almost continuously since I turned it on a couple months ago.  I'm over 700 digital QSOs, 0 SSB (it'll come, no rush) and 0 CW (printed up a key, just need to wire it up).  It's been, simply, fantastic.  I'm so very glad I went with the uBITX as my first HF rig, the experience with both the product and the support here has been more than I could have imagined.  It's what I got into ham for, to explore, to learn, to discover to get that spark in the mind of "ah ha!".

I wouldn't change a thing, even my dreaded WX2822...where I got to down convert to 12.1v instead of running at full 13.8.  If I had wanted to make eleventy-seven DX SSB QSO's in the first week then I wouldn't have picked the uBITX.  I don't need that, I yearn for discovery and and exploration.

I'll add that I have a 2nd uBITX still in box that I need to wire up and put across town.  I'm super interested in not just digital modes, but data modes and having my own testbed with rigs across town and network access to each end will be great fun.

Having just gotten off my bi-weekly company-wide engineering review, I must confess to having a bit of difficulty separating some of the uBitx discussions from my commercial product development (IOT and security).  The topics are often similar.

What I read on groups.io seems more like spirited creative discussion rather than bickering. Folks seems respectful of each other, but have informed points of view. I have been a working hardware and software developer for almost 60 years, but still learn stuff from the group every day.

Thanks to Farhan for being the Godfather of this product line while never letting ego block him from evaluating outside ideas fairly - unusual traits. Thanks also to so many group members for sharing their hard won technical skills and knowledge so freely. I hope to be able to contribute in kind over time.

Re: Mic doesn't work in bitx40 #bitx40

Thank you for your reply, 

I build my own bitx and bought all the component by myself.. The mic element was an electret condenser mic. I wired it up according to the datasheet..
Maybe there was something wrong with the wiring. But all the connections are good and the schematic are exactly the same with the schematic in bitx40..

Re: Newbie instructions for loading software in Raduino #firmware

Thanks these instructions will get me going.

You might have seen that I have been strugling to get my uBitx to work and I am now certain that I have a failed Raduino board since it doesn't even want to connect to my compuer.

Thank you for confirming that the Raduino is the same board as an Arduino. I was assuming it was but "assume" is a very dangerous word so I rather confirmed :-)

I asked Farhan about how to obtain a new board but rather then waiting for his reply and mail from India I might as well buy an Arduino board locally.


New question:
The blue (r)arduino board is firmly connecthe to the larger green board. Before I continue and apply more force is this indeed a part that can be unplugged or does it need to be unsoldered?

The Raduino board is NOT an arduino board.  The processor chip on the board (NANO) is an arduino but the

Raduino board is NOT from arduino.

Rogier,

Please be aware that on Windows systems it may be necessary to load a driver program.

Apparently there are two variations of Arduino Nano, and one of them is not automatically
supported with Windows drivers.

see https://www.rastating.com/installing-drivers-for-an-arduino-nano-in-windows/

for more details.

you may not have a bad raduino

Failure to connect may be due to wrong USB driver, wrong board selected (under tools), wrong port selected (under tools)
or maybe even a bad cable.

I will not suggest more than at for now as for me it all old hat and I'd likely skip a step critical to someone new at it also
unless you are using Mint Linux version of the IDE what you see might be different.

However if its new and does nothing are you sure power is getting to it?

Most dynamic mics are like speakers with 50-500 ohm voice coils, Most are not very compact
with an OD of 10MM and up to as large as 30mm.  That is at least true for ones I have.

Electret mics ar small cartridges usually 6mm to as large as 9mm in diameter with two
terminals.  The ground is the terminal that connects to the metallic shell.

Hi Allison,

It powers on but its unresponsive to any input from the rotary controller or the funktion button.
When pressing the reset button it blinks for s second showing the version of the sofware thats it. This also happens with the board removed and only powered by USB.
After connecting it directly to my iMac and using the Arduino application its not showing under the available ports in the Tools menu.
When I check the USB ports in the System report its not showing there either.

Hey Joe, good to see you taking on the uBitx!

I don't think Farhan has not released mechanical data, but here's gerbers for a Raduino replacement
that Nik may have gotten right through careful measurements.  Perhaps you could contact him
on how these dimensions were arrived at.
    https://groups.io/g/BITX20/message/42237

You've got a busy website:  https://w3jdr.wordpress.com/
The improvement to the biasing of Q70 at the audio preamp seems like something
easy to do and well worth trying.

I've been playing with Blue Pills also, was thinking perhaps putting just the processor chip 
down on a new Raduion PCB would be worth the trouble, gives far more IO than available
from the Nano form factor.  The STM32F has pin compatible processor chips through a wide
range of capability, here's a selection of LQFP 48 and 64 pin parts:

Top end parts such as the 511-STM32F405RGT6TR include an FPU.

The Mac can have trouble talking to the CH340 USB chip on the Nano clones
requires a special driver.  Here's on possible solution plucked from a very long thread:
    https://groups.io/g/BITX20/message/47747

Your USB cable may have been built with only two wires, suitable to supply power but no data wires.
Try the USB cable out on some other equipment, see if it really transfers data.

Lots of other things could go wrong here, it can be frustrating.
But if you keep plugging away and asking questions, it will most likely come to life.
