Dan:

Yep, the baud rate on the Serial monitor must match that in the program code. Otherwise, you get either no output or a derivative of Mandarin.

I have not looked at the KD8CEC software so I can't help much there. Just keep in mind that all of the source code files for a project (i.e., sketch) must be in the same folder and that folder must have the name of the file that contains setup() and loop(). That is, if a project has those two functions in a file named myProject.ino, the directory MUST be named myProject.

Several questions.  The V1.2 KD8CEC says you need to set a flag for V5

I am a retired EE.  I did some programming in the 80s and 90s.  I
wrote a 4000 line program to do active and semi-active radar

if written in C.  They didn't, actually they were slower compiled with
the QuickC compiler.  Programming tools changed so often back then I
got tired to trying to keep up with it and got away from it.

I am looking for hex files so I can use Xloader to update my uBITX V5
which I recently completed.

Phil -

Ian Lee's CEC firmware dispenses with the variable speed tuning.  You set tuning increments - and they can be a low as 1Hz.  

You don't say which version you are on - but it works well with the stock 16x2 display on V5 and prior.   It does everything I want and runs on the stock Arduino. I have upgraded to the 2.8" Nextion using the CEC firmware and I am very happy with it.  The CEC firmware does not and will not work with the V6 display.  For that you need to check out some of the other alternatives.

73 and good luck,

Hi Dan - 

A good place to start is ubitx.net - the links on the right hand side of the page take you to the correct pages.

You don't need the IDE at all if you just want to load the hex files.  

As Evan said, you can get the HEX files from Ian Lee's GitHub - 

https://github.com/phdlee/ubitx

If you do want to build the CEC files from source that is straight forward also.  You need to unzip the source into a folder.  Be aware that  a requirement of the Arduino IDE is that the folder that the sketch source is loaded into must be the same name as the main INO file for the sketch.  If you can't figure it out,  I can identify the INO file for you and point you to the #defines for V5 and for your particular display when I get home this evening.

If you want to learn programming for the Arduino - just follow the examples in the book and you should be well on the way.

Don't hesitate to ask questions - we'll do what we can to help.

Good luck and have fun!

Dean

Re: uBITX V5 Firmware Hex Files

The hex files are in the github repository listed in my response before.  All of the versions are in the zip file (uBITX_CEC_V1.200.zip), with the descriptions of which files to use with which display to use in the FileNamesInfo.txt file in each of the folders in the zip file.  The name of the folder tells you which version of ubitx to use.

There is the github link again:

Re: Made Mods to V3 uBitx - no longer transmitting #ubitx-help #v3

_Dave_ AD0B
 

K1 provides voltage to all the other relays when in transmit. I would guess that the agc might be power from pin 3 of k1 so that it turns off when not in receive. Pin1 K1 drives pin 8 k3.

As far as I can tell,  kt1-3 should not have DC voltage on pins 1 or 12 as they carry signal only.

Re: uBITX V5 Firmware Hex Files

Dan:

Start with a simple example source code program to begin with. Hook up your Nano to the USB port and install the IDE as explained in the book. Then load the Blink program (File --> Examples --> 01. Basics --> Blink is the menu sequence, which is also explained in the book). Make sure you have the board set to Nano (i.e., Tools --> Boards) and you've selected the USB port connected to your PC/Nano. Now click the Compile/Upload icon (just below the File menu option) and you should see the Nano blinking.

If the IDE does not upload the compiled code to your Nano, you may need to download and install the CH340 driver. Just search for "CH340 download" and install the driver. If it still doesn't upload, you may have a Nano clone with an old bootloader. Go to the Tools menu and look for the Bootloader option. If you see it (you may not), select "Old bootloader" (those are the exact words, but close enough). Now try it again...it should work.

Mess around with a couple of other example programs. When you feel comfortable doing that, then compile/load the KD8CDC software.

Sorry to hear about your problems with the uBitx.

If you are determined to part with it I am interested as I am looking for a case to house a bare V3 set.

Re: Made Mods to V3 uBitx - no longer transmitting #ubitx-help #v3

Steve - KE0VCD
 

I've checked all of the wirings against the instructions.  I believe them all to be correct now after reattaching the CW connection. 

On 10m SSB, 
The K1 relay seems to be working fine.  Keyed-up and not.   However, there isn't any power making it to the K3 relay.  The only thing that appears to be between those 2 relays is the AGC mod put in by the previous owner.   

Pins 12 and 1 on the KT1, KT2 and KT3 relays are all 12v.   I don't understand why both of those pins are 12v. 

There isn't any power to the 12 and 5 pins of those same relays. 

I rechecked the xmit power meter with another radio to verify the cable and unit are still working.  They are.

Can someone check the capacitance of c81 in circuit and see what value you get. I get 12.nf when I go across that particular cap. Far from 470pf but then again there is other circuitry to mess with the LC meter.

Re: Tuning knob behavior

Curt
 

Phil

my first reaction - no way I can operate this tuning control, especially since I 'used' to speed up when I hear a signal.  then I tried someone's custom tuning firmware - I didn't like that either. 

since then, I have adapted.  if you don't need the fast tune feature, the firmware can be taught not to do that.  I am still using stock firmware, for now.  Very popular is updating to the CEC firmware, and also there is the W0EB/W2CTX firmware.  your display strategy may influence your choice. 

I am doing CW fine with 50 Hz, and voices sound okay - but I don't have perfect pitch to play a violin. 

Operate whatever version you have - get some more experience, then research the alternatives.  Perhaps learn how to merely slow down the how the existing tuning algorithm works - maybe someone has made this fix available.

How do people feel about the way the tuning works?

You do need a way to tune rapidly across a lot of spectrum, which is why
many radios (like the ubitx) '"accelerate" the tuning when you turn the
knob rapidly.

But I have always found this disconcerting. In the "good old days"
before synthesized tuners, you knew that if you turned the knob say 1/2
turn to the left and then 1/2 turn to the right, you'd be back on your
original frequency no matter how fast you turned the knob. That doesn't
happen here unless you turn the knob slowly enough to avoid triggering
the acceleration.

Heathkit (remember them?) had an interesting feature on one of their
flagship radios: there were two finger indents in the knob, and the
tuning speed depended on which indent you used. Never actually had one
of those radios myself but it seemed like a good idea.

I suppose this is one of those things that boils down to personal
preference. Don't want to start an argument...

Oh, and I think the 50 Hz tuning step is too small, but I haven't worked
out whether the synthesizer in the clock generator chip can do smaller
steps.

I guess I'm just spoiled by SDRs. My own SDR can tune in arbitrarily
small steps. A millihertz, if you really want.
