Thanks Jim,

I need to order some more chip resistors anyway so your input is helpful.

Good Idea Dave,
I did that on one of mine earlier.  I used 1206 size, but 0805 might fit better.  No current so wattage is not a factor.

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).

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.

Re guarding SI5351 Boards, I still have Bare PCBs that are stand alone I2C 5V driven.

They can have headers top or bottom for connectors or plug in.

They both have proper level translation for I2C with 3.3V regulators.

The larger one is Lotsa Clocks, has the 20 Pin SI5351 with extra address jumper and 8 Clocks.

Here is a picture of them.  Bare and stuffed.

The bare PCB is $4 and $6 for Lotsa Clocks.  Include postage US and PayPal.

Thanks Great Firmware.
It's works my ubitx very well.

I modify two small function.

#1 TX only ham bands
It MUST need Japan reglation.
(Japan need Application for Transmitter spec inspection.)
In main loop,Check current frequency,It's valid,ham band,process sense key or PTT .

#2 In CW mode, Push PTT to TX CW(every Straght key mode)
For emagency use and ATU tune.

Re: #ubitx New I2C/Digital I/O mod & firmware from W0EB/W2CTX #ubitx

Jim Sheldon
 

Bob, I think after I posted that, Amazon ran out of them.  Any I2C controller should work as long as it can provide 5 volts to the LCD display while talking on the I2C bus with only 3.3 volts to keep from smoking the VFO generator in the uBITX.  

If the controller uses the PCF8574 chip and does NOT have pull up resistors to 5 volts (around 4.7K) on pins 14 and 15 of the chip it should work.  If it does have resistors on pins 14 and 15 just unsolder them and it will still work.  The lines used for SDA and SCL in the PCF8574 are "open drain" in the chip so it can actually talk to the Nano reliably on the I2C bus without those reisistors as it will use the pullups to 3.3V in the Si5351.  Almost zilch current draw there so no problem.

There are different suppliers on Amazon that sell that same controller - Here's a photo of the board itself on the back of the display (I believe this picture is in the hardware manual I sent -).  It's the one with the LED lit up on it.  The two resistors that were removed are the two that were right next to the PCF8574 chip on the same row as the LED.  Do a search on I2C controller and hopefully you will find one of them.

In the doc you mention the need to be careful in selection of the I2C display controller and talk about a board from Amazon by seller "IC Module". Would provide a link? My search for IC controller on Amazon doesn't turn up one from that seller.

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.

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.

Re: Tuning clicks on bitx40 #bitx40help

radioant@...
 

Thanks for the reply Jerry. And thanks for the advice. I tried putting a 1000uF and a .1uF cap across the input of the regulator and it made no difference. I even ran the raduano with a separate power supply and the clicks were just as loud.  When I observed the tuning clicks on the scope at the output of the vfo it looks like the RF signal stop's then the tuning pulse then the RF continues. I hear this can be a. problem. The version of software is I think 1.01 when the unit is turned on. Thank you Bob WB2TFG.

First Microbitx QSO

Charles D. Smith
 

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 Firmware (CEC) 0.30 released (Test version). #ubitx

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.

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.

FS: Bitx AGC Kits

 

I have 10 kits ready to go with another 10 for kits or pre-built.

This was posted on DuWayne KV4QB's site found here 

Thank you DuWayne for the use of the board layout and files!

All kits will come with:

PCB x 1

Parts placement layout x 1

2N3904 x 1

2N7000 x 1

47uf x 2

1N4148 x 1

100R x 3

100k x 3

10k x 1 this is extra for the user to play with attack or input values.

2k2 x 1

.1uf x 2 unmarked tan

If you lose anything let me know I will send you a replacement.

This is the 3rd run of the boards, many users here have this AGC already in use myself included. It was setup for the Bitx40 but I have not tested it with the Ubitx yet (should work).

 

Cost and options:

#1 - Kits 13$ shipped

#2 - Pre-built OT service 15$ shipped and tested

Please contact me before you send any money the last two times I have offered just the boards they sold out in under 24 hours.

As before I am not yet a store so please have patience and 1st come 1st serve. If all goes well I have plans to roll the income from this run into purchasing Eagle and making a new adjustable AGC with all surface mount, surface mount led zero beat and more!

Contact me directly for more information or orders: dherron at live dot com

I will send you a confirmation and direct you to my paypal for payment.
