I use git for version control, but it seems to be difficult to trace history when the file name changes.

Instead, I will create a separate file to keep track of which files have changed each time I deploy.

All filenames are now cleaned up.

Since Version 1.070, there was work such as splitting and merging files to support various hardware.

I will publish Version 1.073 (Beta) within a day.

Thank you for testing the firmware.

Rod, All

I am always thanking Rod.

And I'm sorry to interrupt Rod's work with too many changes in functionality.

1.072 will be tested and will be released as 1.073 Beta.

Several minor ones have been added.

Please wait for a day or two to download the code or firmware.?

Perhaps 1.07x will continue to be a Beta version.
Frequent formal firmware release seems to be inconvenient for some people, so I try to release it after various tests.

I think Version 1.061 is a stable version.?I know there is some nice firmware based on Version 1.061 and I will install it on my Spare uBITX.

Version 1.061 and later versions are also based on Version 1.061.

The Portable version and the various language versions are all excellent Firmware and I share code with them.

Please wait for a day or two?, I'll release version 1.073 beta after testing in various environments (including Linux).

Hi All,

Ron, W7HD, points out that downloading the KD8CEC 1.072 can be a problem

because version 1.072 does not appear in the list.

It is necessary to click on the Branch button, then use your mouse wheel to

scroll down until the version1.072 is revealed.

Best to All,

Rod KM6SN

See below for an excerpt:

Download the CECFW source code from github

For this example we will be using version 1.072.

<Image4>

Click the “Branch” button to select version 1.072, then click “Clone or download” and click “Download ZIP”. Unzip the downloaded file and make a note of the folder location, or move the unzipped directory into your arduino sketch folder.

Jack,

I agree that there are many people standing on Farhan's shoulders and he has certainly created/generated a huge interest in his uBIT-X design point..... key parameters being that the cost is being held low for a simple design to allow more people to try modifications if they want to ......AND he's allowing others to start small businesses and learn skills. I think the latter, in itself, is great.?

Message counts of ~2000 per month definitely indicate a huge interest.

My point was that there are many steps in the progression from the uBIT-X that arrived in the mailbox, TO one that has slight modifications, TO more comprehensive AGC hardware, audio amps, etc, TO SWR indications, 4 line displays, more keyer features,
TO DSP and other SW defined modes, RPi, Teensy 3.5/3.6, large touch screens, etc ......you get the idea. Many options. The point is that you can take the path and get off at any step. I personally want to go as far as I feel makes sense to me (staying with the Nano or an Arduino based derivative and basically "Keeping It Simple") with a result that I think I can reach, and a Transceiver I will/can use. Some of the guys that want to Hack-to-the- Max ....more power to them but the number of followers will drop off pretty quickly and I for one will become a (maybe) drooler, not a follower.? ?

Buddy:

There are some very interesting filters available in software where you can not only set the "center" frequency, but also the edges where the skirt "knees" are located. When I'm listening to code, I dial 'er down pretty tight as I find listening to the Big Bang during a CW session distracting rather than soothing. It all a matter of choice.

Hey Gordon,

Agreed about the super duper narrow filters. With all of the ways to crank down the bandwidth and peak the audio and reduce the noise and what not that are on my KX3, I rarely use much of that myself and, unless the bands are very crowded, open the receiver up some besides. Strange as it may sound, I find the background atmospheric noise soothing. Well, except maybe not so much the 80m static crashes.?

Now, after 30 years of being a ham, I’m interested in trying some kit building myself…it’s one aspect I feel like I’ve missed out on…especially now that I have a willing assistant :-) Still…being blind, these tiny parts make me a little nervous, and surface mount stuff is just right out. Anyway, think my YL and I can tackle a UBitx sometime soonish.?

Ehhh! Listening to cw with a 2.someKHz filter is good for you! It will hone your cw listening skills and let you learn to pick the right signal out :-)?

In all seriousness, Gordon’s suggestion of an audio filter is a good one. While it’s not really the same as a filter in the receiver, they’re pretty good…or can be…and certainly can be very effective. I reckon that a DSP-based filter would be a bit beyond the capability of the Arduino. Also probably not exactly cost effective as compared to the rest of the radio.?

Do remember this is a really low-cost radio, and you probably won’t get Icom performance, or probably not even Xiegu performance, out of it, though I’m sure what you will get will be pretty decent…especially given how popular the rig seems to be.?

I've heard that the ubitx doesn't work very well for CW due to being too wide in the receiving end. How are some of you correcting this? Particularly, how can someone who can handle a soldering iron but is not an electronics whiz, adapt the ubitx for practical CW operation??

Jerry:

I realize the power the Pi has and I'm familiar with compiler design and grammars, as my old software company built and marketed its own C compiler for DOS back in '80s...without yacc! Al and I have been through a pretty rigorous ?C decision process for our Jackal project, looking at Pi, Mega2560, Due, Mega Zero, and the new Protoneer board to replace the Raduino/Nano board. We settled on the Teensy 3.6. One of our goals is to encourage hacking by those who are already familiar with the ?BITX, and that suggested sicking with a processor that could run in the Arduino IDE. The Teensy 3.6 has

• 180 MHz ARM Cortex-M4 with Floating Point Unit
• 1M Flash, 256K RAM, 4K EEPROM
• Microcontroller Chip (PDF link)
• USB High Speed (480 Mbit/sec) Port
• 2 CAN Bus Ports
• 32 General Purpose DMA Channels
• 22 PWM Outputs
• 4 I2C Ports
• 11 Touch Sensing Inputs

and costs a little less than the Pi. The FPU is important in many SDR's that use FFT algorithms, and the Teensy has a very good FFT library. It also has a terrific audio library that we are using in our filter elements. However, to me, the critical elements were that the 256K of SRAM removes the real bottleneck of the Arduino family and there are a host of relevant libraries for the processor. Atmel needs to get its act together and boost its processor resource base if it wants to stay competitive. (I taught an assembler course on a Z80 back in the '80s and, you're right, the 328 reminds me of it although the memory architecture's a little different.)

Anyway, we experimented with Pi and other processors for over a month before we committed Jackal to the Teensy. We made the right choice for us. Al and I will be showing Jackal at the FDIM conference...I think it's pretty cool and brings a lot to the table. That's not to say that someone shouldn't give Pi a try as a Raduino replacement. It's just not for us.

It sells for $5 because it is of the current decade.
Whereas the ATMega382P is roughly in league with the Z80
I was working with back in the 1970's.

That said, the Nano is a fine choice for the basic uBitx.
Not all that much it has to do.

The RPi Nano would be good if you wish to implement standalone SDR,?
with a full waterfall display out to an HDMI monitor.
Or could be used as the Arduino IDE host when programming your Nano.
The top end Rasberry Pi 3 B+ does everything I'd want in a home computer for $35.

First, it does not have a home in the Arduino IDE, where most of the ?BITX work is being done. Second, it doesn't have the depth of add-ons that the Arduinos do. Those that do exist seem to be more expensive. Third, most of the work on Pi is either done in scripting languages or Python, neither of which is popular on the Arduino.

If you need more horsepower, consider the Protoneer (eBay 282786290858). It has 256K of flash, 32K of SRAM (HUGE benefit), and is clocked 3x faster than the Nano at a cost of $15. It looks very promising.

No way should anyone hate anything.? It may be an eye opener to some what can be done with a modern micro-controller.? I am glad Jack gave honorable mention to the Protoneer.? Before I ordered it last week, I came up with zero hits for Protoneer here. Thought I might be a little crazy since very sharp minds are active and voicing their opinions.? I hate to see great? software work by Ian and others be limited to choices based on the flash memory space of the Arduino Nano, which is also consumed by the boot loader.? The idea is this may help those that want a lower end "modern" 32 bit digital solution with a reasonable amount of SRAM for their uBITX with a small $ additional investment.? Even the Pi fans might find a need for a little more horsepower in the micro-controller.? Then again, I could be blown away by a pure Pi controller implementation.

I don't think any of us want to someone else to become a drooler, well at least I hope not.? From what I see here, it is enabling.? Sharing knowledge.? Albeit overwhelming at times.
The dust will eventually settle from the excitement stampede unleashed by Farhan, and the path you choose will become clear.? Hopefully everyone will choose to ride along, and the world wide amateur community benefit from your participation.
