This may be due to the si5351 library version that is used by the original
stock firmware v1.01
Try upgrading the firmware
It has built in si5351 routines (no external library) and some other
patches as well to reduce the noise.
Using shielded wires to/from the volume pot also helped a lot in my case.
But I must confess I never got rid of the clicks completely. I can still
hear them when the antenna is disconnected.

Today the following items were added to
The following news story from the day before also had significant
additions as a result of a new email posting on the BITX20 group:
Thanks for all the positive feedback to the launch.? I am pleased
that people find the site is heading in the right direction. I
have been busy taking on comments and making some changes to the
website.? I have fixed the issue with the news categories and tag
cloud not working properly.? The website will no doubt evolve
further over the next week or two!?? But, I didn't do much on the
mods summaries today ... too much other stuff to do.
I have had a number of suggestions for content come in, many of
which were actioned immediately.? If you want to feature a product
that enhances the uBITx just write to me. I will find some way to
do this.
I have had one offer of help, which I will be taking up!? If a
few people are willing to add newsworthy items on a roster basis,
the burden of keeping the website up to date will be eased. The
"FAQ content" will change more slowly than the news content.? Good
writers are needed, but there is not a lot of work as content is
sourced directly from email list postings.?? Summarising postings
(or elaborating if they are too cryptic) and improving
readability, correcting spelling or grammar is all that is
required.?? I am linking each to the BITX20 email reference to
make it easy for people to browse the relevant thread.
A typical day will probably have around 2 news items.? Today was
a bit atypical, as list activity was way up, and there were
several interesting developments today!
I will respond separately to the email from the list moderators.

I should have posted this before.? To any and all outside the lower 48, if you want a board send me your mailing address and I will check with the post to see about cost.? It may or may not be worth it in some cases but I will do my best to accommodate everyone I can. -- David

PiZeroW Controlling a uBitx
Anyone thought about using a PiZeroW (or even a regular RPi) for controlling a uBitx?
I thought to myself, while pondering my design decisions, "Hey, a PiZeroW is $10.? A Teensy3.2 is $20..."? Looking quickly at the pinout, it has spi and i2c, and a few GPIO's.? I don't have any experience programming the raspberry pis, but adding an i2s audio dac (or two) could easily do DSP audio, spectrum display, etc... I have my RpiZeroW hooked up to a 3.5" TFT touchscreen display I got off amazon... ()
Mostly just curious.? Doubt I'll change directions with my top mod PCB, but it certainly could be an interesting option (The RpiZeroW consumes ~250mA @ 5V as I recall)

Re: uBITX woes, feeling disheartened.
#ubitx
The band change relays operate only when the PTT is pressed in the uBitx. I have made
mods to keep the relays operating in RX and you can hear the band change then only.
Disadvantage is that the RX current consumption increases when relays are always on.

Re: uBITX Firmware (CEC) 0.30 released (Test version).
#ubitx
Dave
Thanks for your information.
My modified code (Ron's cw keying) does not use A7 for factory shipping users.
Until now, the firmware concept was applied without modification of the hardware.
I am going to end this project because I do not have any further improvements without hardware modifications.
When additional uBITX?order arrives, I try to do a variety of fun H / W hacks.At that time, I will use A7 as Paddle and connect to S.Meter.
Ian KD8CEC
Ian?
The v.30 with Ron’s CW Keying code does include adding the 4.7k pull-up at A7, as a modification to hardware.
I’m planning on adding both 4.7K chip resistors directly on the pads of the Raduino so there are no loose resistors to mount at the key jack(s).
Dave WI6R Sent from my iPhone On Jan 27, 2018, at 2:39 AM, Ian Lee < kd8cec@...> wrote: I have not posted it on my blog separately since it is a test version. When the test is complete, ?write a usage and post it. I am writing for someone who is interested and test.? If I get an error report or a fix, I'll fix it and make it into github's 0.31 branch. Here is a brief description of the change from 0.30. improved CW Keying, Frequency Tune and CW performance according to users' requirements. In particular, CW Keying applied ron's logic for use with original hardware. also made it possible to set the CW Key ADC range to reduce errors in CW. ADC monitoring function is added to know the exact resistance and key contact status.
I thought that if you set your own ADC range using the measured values here, you would get an error.?I need to test these things, so I leave this post. removed all existing sources related to frequency tune.?And i applied threshold, weight about speed, and steps. The problem of changing the frequency at the moment of catching the knob has probably disappeared. when the threshold has been exceeded, start frequency changing,?i added some logic to prevent the thresholds from becoming unnatural. If you want to fine-tune, slowly turn it and the threshold will be applied continuously and change very slowly. The tune steps you can select now are 10, 20, 50, 100, 200, but you can change them in uBITX Manager 0.31 (now working)
You can change the step by pressing the function key for a long time. If you keep pressing it, Diallock will work.
The ham band movement applied at 0.28 was set to 0.30, so that region1 was set as the default.
Of course, you can change to the previous operation state by pressing the function key in the band select menu for a long time.
And like the 0.28 version, you can set up to 10 frequency bands in uBITX Manager to suit your country or your liking.
Please refer to below for the improvements and how to upload firmware and more detail. The source and compiled firmware can be found in the release below link.

Using a hamstick hanging out of my apartment window, I just made my first qso (ve3rb) with my microbitx! ?On 75meters no less!!! ?Often I listen on this band with my mkars80, but I never transmit. ?(Winter field day is active!)
I also just received an Arduino and recently got W8TEE’s “projects” book. Slowly, I’m going to teach myself how to “code.” ?
I’m going to play with this radio as-is for a while and learn a lot more before changing the code or doing hardware mods. I actually find the tuning easy to use and the tx/rx pop doesn’t freak me out because I listen mostly.
I put the radio in an test instrument case I got at a hamfest many years ago. I only had to buy the little 10cm cables to connect separate the lcd from the raduino (but it took three weeks because the amazon vendor sent the wrong cables -m/m- the first
time. Ugg! ?They said keep them and they offered a partial refund. The correct ones came today!)
These photos show part of the assembly process.

Re: UBITX Touch Control TFT Display
The device the review refers to, was for an UNO and not the atmega2560, huge difference in number pins and performance. We only suggest an Atmega 2560.? Low cost,and tons of Spare I/O a The UNO is not recommended.
Joe
All valid inputs.
But with the atmega2560 the user has more inputs and output pins then one could ever use.? With the radio all wired I would estimate more than 25 spare pins
Joe
VE1BWV
I had never heard of , that looks like a good steer.
They have some nice Arduino starter kits.
However, their 2.8" TFT display is not well documented, and burns an awful lot of pins.
Here's a reply to a question up on Amazon:??
? ? ??I just went through all of the pins marked on the board and the code for the support libraries.
? ? ? It appears that the display hogs all of the pins with the exception of the A5 and the serial I/O pins 0 and 1.
? ? ? This pretty much precludes the use of any other peripheral devices using Wire, SPI, or I2C.
? ? ? The SD card uses digital pins 10 through 13, so if you don't need the SD card, you can snip those pins off
? ? ? (and don't include the SD library in your project). Otherwise the options are limited.
Not what I'm looking for.??
I'd prefer a display with just a 4 wire SPI interface, and power and ground.
Recommendations solicited.
Regarding the si5351 PLL chip breakout board, in addition to , there is also and
Hans of qrp-labs is active on this forum, a kit for his board is $7.75
? ??
The others come fully soldered up, which some may prefer.

Re: UBITX Touch Control TFT Display
Have a look at the Digole range of displays.
They can be driven via UART, I2C or SPI. Jumper selectable on
the back.
Various sizes available. They have an
on board PIC which simplifies the usage of them and reduces code
space required in Arduino.
They are not the cheapest displays
around but having bought serval and with no problems of poor
quality, can reccommend them.
