Hi,

I've managed to get the CEC uBITX Memory Manager running and the uBITX_CEC firmware uploaded to my uBITX from my Mac.

uBITX Manager:

I have Microsoft Visual Studio Community (a free version) already install on my Mac, so Mono was already installed. When I first tried to run uBITX_Manager it crashed with the warning "The Carbon driver has not been ported to 64bits, and very few parts of Windows.Forms will work properly, or at all".

After a little Googling I found the solution was to run mono in the 32 bit mode with the following command:
mono --arch=32 uBITX_Manager.exe

The uBITX Manager UI runs painfully slow on the Mac. Scrolling is next to impossible. But, with patients it is useful. The buttons will be covered over often, but just hover the mouse over them to bring them back.

The manager crashed when connecting to the USB serial chip unless the "Linux" mode check box was checked.

Also, I already had the USB serial driver installed because I'd purchased a temperature logger from this company "Elitech" and the driver was included with their software. However, the Mac "Homebrew" installer now has an updated signed driver for the CH340 chip. I found this on Github: https://github.com/adrianmihalko/ch340g-ch34g-ch34x-mac-os-x-driver 

uBITX CEC Firmware Upload:

I decided the best way to upload the firmware was through the Arduino sketch IDE. I downloaded the firmware source code and compiled it. The only issue I had with comping the code was I named the base directory with the version number of the code as part of the name. The source code wants to be in a directory named ubitx_20. I installed this directory under the "~/Documents/Arduino/" directory where all my other sketches are located. I have a fair number of libraries already installed, so it is possible you may need to add a library here or there if the CEC uBITX firmware needs any other libraries.

Running the Firmware:

The firmware seems to be running just fine. I used the uBITX Manager to copy the memory values from my Radiuno and save them to a file. I'm particularly interested in using the CAT interface to control my uBITX from a Raspberry Pi.

This software and the fact that it exposes all the memory settings, may have already started to point to some of the mysteries involving my radio. I have noticed my receiver is about 100hz low on sideband signals. That is no big deal. However, it looks like my transmitter frequency is about 1khz low on CW. I can't quite wrap my head around the standard factory setup calibration method and if it could result in an unwanted difference in the transmit and receive frequency calibrations (or fix it). 

I wanted to try the IF shift to get a handle of where my radio may be operating in the 12Mhz crystal filter bandpass. Interestingly, tuning the IF shift up a kHz makes the received SSB signals much clearer. So, maybe my uBITX is out of calibration. 

There truly are a lot of numbers and such to digest in the uBITX Manager, but I'll read the posts (and the synthesizer chip's app notes) on how the calculations are done and then I'll know for sure when my radio is calibrated. At least now, rather than not quite knowing what the assumptions are in the factory calibration, I can directly experiment with the values to understand them and see what works.

the JacKAl board looks great.  The CW filtering options are first rate.  The second encoder is excellent!

Audio filtering is nice as are all the options..

Whoops. I just posted info on the ubitx Raspberry pi setup. Working great after a long day of troubleshooting and cussing at Linux.  Nice setup.

Note that without a RF gain control you have to jockey the volume control to keep the signal out of the red when a strong signal blasts.

Re: pin 2 of raduino board seems to have gone to CW TX full time after boot message.

A bit off-topic for this thread, but still interesting...

The Arduino Nano includes a 12 MHz oscillator for USB clocking.  This can cause
interference with the 12 MHz IF on some versions of BITX transceiver.  It can also
contribute to unwanted mixing products (birdies) during reception.

The Pro-mini does not have a 12 MHz oscillator.  This means you must add a
plug-in TTL-USB adapter which does include the potentially problematic 12 MHz
oscillator for running CAT control.  This raises a question...has anyone tried doing
CAT interface using just the D0 and D1 pins on a Pro-mini with a voltage level
translator and using the serial port on an older model PC?

Its not like there is engineering involved as its already defines and the bootloader

I picked up a while back via amazon 10 pro-minis for about 2.35 each! 
If I have to I can substitute the pro-mini with a bunch of wires to put the right mini pins

boards use the exact same chip.  I have a proto Raduino using a pro-mini,
Adafruit Si5351 board and a cheap backlit 2x16 LCD.  Words exactly the same
save for I use a FTDI RS232TTL-3V3 to program it instead of a usb cord and set 
IDE for the demilove rather than nano.

Jack,

I've used Smart Prototyping for all my boards the last 2 years. The quality is very good. I also used them for 2 small prototyping runs (only 5 and 10 boards). Those board were hand assembled. I thought the prices were reasonable. I let them supply the parts and the prices they quoted were straight off of Mouser's website. They will also let you supply parts if you want to go that way.

Should work fine.
That's all the FTDI/CH340 chip on the Nano clones does.
All USB communications go through the UART pins D0 and D1 via the CH340.

When the customer gets a Nano in their hot little hands for $2.50,
the manufacturer might be getting half that. 
Spending a buck or so on a processor is a very big deal. 
Especially with 100,000 hobbyists scouring ebay for a listing that's $0.05 less.

You wouldn't think they would bother with cheating on IRF510's either, $0.50 on Mouser.

Most Nano clones seem to work amazingly well.
But I can easily believe there's some that aren't quite so amazing.

You're forgetting one point - shipping costs.  Some charge very little, others charge way more than the device is worth.  It's still worth shopping around, or at least combining orders into one shipment.

New Board Naming Contest Winner #ubitx

Jim Sheldon
 

The naming contest for the upcoming new Raduino replacement board from W0EB/W2CTX/N5IB is over and the winner is Vince Vielhaber, K8ZW who submitted "BITeensio" (pronounced Bit-EEN-cio) as the winning entry.  Vince has already been notified that he has won the contest.

There were a number of really decent and catchy entries, but in the end, by unanimous decision of all the judges, Vince's entry of BITeensio was declared the winner.  Vince will be receiving, as his prize a complete board kit for the BITeensio card as soon as the production boards arrive from the factory.

Thanks to all that participated.

Re: Raduino CAD Files

W3JDR
 

While laying out my substitute Raduino PCB, I think I might have discovered a fatal flaw in trying to use the "Blue Pill" as a substitute for the Arduino Nano. It seems that the Blue Pill board has no reverse isolation diode or any other reverse current isolation between the USB power source and the external 5V power source. There is a direct connection between the USB connector +5V and the 3.3V regulator on the Pill board. This means you can't power the board from an external 5V source while the USB connector is in use. In fact, trying to do so will probably fry either the PC's USB or the external 5V supply.

This is a major bummer. It seems that virtually every cheap ARM-based alternative board I've evaluated has some sort of flaw that makes it difficult or impossible to use as a Nano footprint-compatible substitute.

Anyone have any insights/ideas besides using a $20+ Teensy or a larger and more expensive solution? I might have to revert to the TI Nucleo; that was about $11, but it had a Cortex M4 core with FPU  & 256K Flash as  bonuses.

Re: Raduino CAD Files

Jerry Gaffke
 

Hardly seems killer.
I'd shut down the USB interface, use the UART instead.
The chips come with boot code in ROM that speaks to the Arduino IDE via the UART,
if you use that you don't need to worry about loading the special USB bootloader. 
And you have to worry about that nasty 12mhz stuff on the USB wires being inside your radio. 
This USB to UART dongle is configurable for 3.3v or 5v IO:
    https://www.banggood.com/CJMCU-CP2102-USB-To-TTLSerial-Module-UART-STC-Downloader-p-970993.html?cur_warehouse=CN

Alternately, on the blue pill I got, the +5v USB pin goes to a feedthru, then over the the 5v pin on the header.
Cut the trace immediately after the feedthru, then add your diode from feedthru to the header 5v pin.

I also have the Hendrix Bix 20.  I think I measured 70vPP on the scope, but my QRP kits dummy load read about 7 watts (with the dC voltmeter method.
I also measure about 7-8 watts output on my antenna tuner.  
I used to get more output (as measured by current when tuning up so may have fried something) but people say the signal sounds good and Im getting out  (1500 miles), so havnt gone after the

Re: Encoder issue

Mike aka KC2WVB <rb5363@...>
 

I've been out for two days, just got back.

It was connected to common ground but thanks for the thought. Right now its out and the one side under a continuity test reads: open, closed, open, closed.....and the other reads open continuously while the shaft is rotated. So that spells defective encoder.

I should have a replacement encoder tomorrow but I am trying to test the Rudino board tonight because I have a nasty feeling it may be corrupted too. I am searching for the voltages to expect on its pin outs. I have the info, I just need to find it.

At least I have the BitX40 up and running so last weekend was not a total bust.

I can think of one error that would result in what you measured... If the ground was connected to one side of the switches instead of the common, then that side would show voltage changes but the other side would never connect to ground. You may want to verify that the connector end is wired correctly.

With all three lines disconnected, power up the system. One line should be at ground, it should be the common connection of the switches. The other lines should be near Vcc.

Let us know what you find out!

I have seen lots of venders at hamfest that seem to have the same thing I orfered from China at about 2 to 5 times the price.

I have bought a few things in the states that are the same as China at double the price (when shipping is included)  to get them fast.  Just ordered  5 of an item in the US that is the same as 10 of the same thing from China.  I don't ever see needing more than 2 or 3 of them and wanted to go ahead and get the item to finish a project.

I have bought several of the nanos from China and they seem to work fine.  Just got in 5 of them for about $ 12.  I did blow out one in the uBITX but it was my fault.  Was playing with it and got a 12 volt wire on the cw or ptt pin.  Not too much trouble to change using one of the China hot air rework stations that cost about $ 60 now.

I may be mistaken,but I was thinking there are 2 different kinds of interface chips on the usb port and you may have to have a different driver for them.
