Re: Swapping Nano's

Evan Hand
 

Martin,
Based on your question, I will assume that you are not using the .hex files and hex loader to change the firmware in the new Nano.  In order to use the source code and make changes, you will need to have the full uBITX_20 master files in the smae directory, and then open/make a project with the uBITX20.h file as the source.  

The above is from memory, so I am sure that there are errors on the file names.  The fact that all of the required modules (end in .ino) must also be included in the same directory as the top level source file.  

Also, I would first do the compile option to test the compile before doing the download.  Again, it has been almost a year since I tried doing this myself, so you would be better off to wait for someone with more recent experience to give you the correct steps.

You can start with the Hex Loader and verify that the uBITX works with the pre-compiled version.

FWIW

Re: Swapping Nano's

Fellow uBITx Enthusiasts:


Attempting to load the CEC firmware to my spare Nano…

I setup the Arduino Web Editor/Create platform/IDE, and successfully loaded the “Blink” program to my Nano, to be sure my PC and Nano are communicating.  I even changed the rate of the blink.


I downloaded the uBITx-1.20 zip file and imported it to my library.  Under the “ubitx.h” tab, I noticed that lines 25 to 35 seem to already be set to support the stock, unmodified uBITx and stock screen, which is what I’m using.


I clicked on the box with the check-mark (“Verify and Save”) then the box with the arrow to upload to my Nano, but it didn’t load and I got an error message saying “‘getBtnStatus’ was not declared in this scope”.


The Blink program is still running.


Does anyone know where my glitch could be?  Did I skip a step?


Sorry for my rookie questions.  So far, I’ve already learned a lot from you all and I appreciate the help.

Martin, AJ6CL

Dear Evan & John:

Perfect! 

Thanks for the info. 

You guys are heroes!

This is just what I needed.

I’ll proceed forthwith.

I’ve made several CW QSO’s using my new radio in its unmodified, stock state.  It is a very rewarding sense of accomplishment for a beginner to put something together yourself and discover that it works! 

I’ll modify, compile and upload the CEC firmware to my spare Nano, then insert it into my uBITX and attempt a calibration, keeping the original Nano as a backup. 

I hope to hear you on the air!

73 es TNX AGN!

Re: Swapping Nano's

Hello Martin,

Welcome to the world of conditional compile.

Here are the lines in the ubitx.h file that you need for the stock standard V5 board (you can copy/paste to replace existing lines 25 to 35 with the text below):

//Ubitx Board Version
#define UBITX_BOARD_VERSION 5           //v1 ~ v4 : 4, v5: 5

//Depending on the type of LCD mounted on the uBITX, uncomment one of the options below.
//You must select only one.
#define UBITX_DISPLAY_LCD1602P        //LCD mounted on unmodified uBITX (Parallel)
//#define UBITX_DISPLAY_LCD1602I        //I2C type 16 x 02 LCD
//#define UBITX_DISPLAY_LCD1602I_DUAL   //I2C type 16 x02 LCD Dual
//#define UBITX_DISPLAY_LCD2004P        //24 x 04 LCD (Parallel)
//#define UBITX_DISPLAY_LCD2004I        //I2C type 24 x 04 LCD
//#define UBITX_DISPLAY_NEXTION         //NEXTION LCD

This generates a program that just fits in the Nano's memory but you have all the features enabled.

Later if you want to, you can remove the features you do not use to make your menu simpler.
This is done in lines 62 to 83. To disable a feature change the "1" into a "0" (zero, not "O").

Example to disable WSPR:
Change line 73 form:
#define FN_WSPR         1 //1044
To:
#define FN_WSPR         0 //1044

The number after the // is an information Dr Lee has provided to indicate how much memory you save/use by disabling/enabling that feature. This is useful if you want to program other functions and need to make some room by removing unused features.

Hope that helps,

Good luck.

Re: GOT IT WORKING including the BFO numbers.Calibration #calibration

d.maccallum@...
 

Attached please find my final cal numbers, i used the memory manager for the master cal tweaks by entering the corrected numbers directly into the display box for the calibration after i up loaded the current values from the MBITX radio then I down loaded changes and closed comm port and disconnected the USB cable. Did this till the MBITX freq display matched and tracked the display on of my KX2 radio. The BFO numbers were generated directly by cranking the numbers for best sounding audio using V1.2 CEC firmware in the MBITX radio.

Also I edited my spreadsheet calculator to handle ABS difference between freq displays, I have not tested it, because my KX2  measured freq was always higher in value than my MBITX displayed value. 

You can test it and fix it if it does not work and pass it along to the group. Have fun..............

73 CU Later on the Bands....I am moving along now to install AGC control, 700 hz filter and tuning indicator..
I installed a BCI filter that I got off Amazon from RTL-SDR.com 2.6 MHz HPF Broadcast AM reject filter. I removed the filter board from it's case and wired it to the MBITX board works great! It's wired between the antenna relay and the receive relay K2 low power RX connection gonna install my AGC control in the same line..

Re: uBITX +12V Fuse: 0.5 amp or 5 amp? #ubitx

Wayne Leake
 

 RE fuses, I bought an assortment of the small glass fuses, plus a bunch of fuse holders.
 So I could use a 0.5 (1/2) or a 1.0 amp fuse in the supply line, plus a 1.5 or 2.0 amp fuse in the line to the PA.
 A 5.0 amp fuse is  more like what I'd need with a 25 to 40 watt VHF/UHF FM rig.
 And maybe a 10.0 amp for my Icom MK II G.

Plugged sound card mic into speaker #ubitx

Rob French (KC4UPR)
 

I've been using my ubitx with the speaker output connected directly to my USB sound card input.  The sound card supplies ~2V for an electret mic, but I figured I was fine since the ubitx output has the 47uF capacitor after the LM386... But I just realized, that is the wrong polarity for a DC bias applied from the USB sound card!  I haven't seen a pop, but am I slowly destroying that output capacitor?

Re: Did something break, and what should I check?

DD5ET
 

I'm new with the uBITX, too, so I'm no expert. Just some initial thoughts.

Regarding WSPR, what you describe doesn't necessarily sound unusual to me. I've got a WSPRLite from SotaBeams and I've had similar experiences. Some days I'll have reports all day, some from halfway around the world (with 200mW transmit power on 20 M). Other days, I'll have only a few scattered reports. Could be several things. Propagation changes, of course, would be the first thing to consider. Also, I've noticed that WSPRnet.org has been very flaky for me lately. I use the DXplorer.net service and they depend on getting data from WSPRnet. Frequently, I'll get a notice from DXplorer that says there's a problem getting data from WSPRnet. When I go to WSPRnet to check directly, it often doesn't respond. Also, there are times when I'll have no reports for hours and then all of a sudden reports start showing up from hours ago. So, it also could just be issues with web sites and reporting delays.

What band(s) are you using for WSPR? What kind of an antenna are you using? Where is the antenna located? Do you know how much actual power your uBITX is putting out with WSPR? All of these things can affect WSPR performance.

I noticed you mentioned noise (but didn't mention what kind of an antenna you use or where it's located). At my QTH, virtually all of my radios are deaf. The noise level here is between S5 and S7 on good days. If I go for a walk outside the town, the airwaves come alive. Even my portable SW radios hear tons of stuff with just a telescopic antenna when I'm away from the noise. If you have too much noise at home, you won't really get a good idea of what the radio can do until you take it somewhere with low noise levels. Take it portable. If it's still having these issues, then maybe you can conclude it's not the antenna or noise and take a closer look at the radio.

Re: Swapping Nano's

That is one of the version listed in the CEC zip file.  It is a parallel interface, with 16 chacaters, so if my memory is working, then the version should end in 16p.

http://www.hamskey.com/2018/04/various-lcd-support-in-ubitx-with.html

prefix   : UBITXV5_CEC_
Version  : Vxxxx (ex: V1.097)
LCD Type : _XXX  (ex: 16x02 Parallel = 16P, 20x04 Parallel = 20P, 20x04 I2C = 20I, Nextion LCD = NX)
Signal Meter Type (Option) : none : Analaog Meter using A7 PIN
                             _S   : I2C Signal Meter using I2C Port

UBITXV5_CEC_Vxxxxx_16P.hex    : It is the LCD equipped with uBITX. Default LCD, 16x02 Parallel LCD
UBITXV5_CEC_Vxxxxx_16P_S.hex  : _16P with I2C Meter


UBITXV5_CEC_Vxxxxx_16I.hex    : 16x02 I2C LCD
UBITXV5_CEC_Vxxxxx_16I_S.hex  : _16I with I2C Meter


UBITXV5_CEC_Vxxxxx_20P.hex    : 20x04 Parallel LCD
UBITXV5_CEC_Vxxxxx_20P_S.hex  : _20P with I2C Meter


UBITXV5_CEC_Vxxxxx_20I.hex    : 20x04 I2C LCD
UBITXV5_CEC_Vxxxxx_20I_S.hex  : _20I with I2C Meter

UBITXV5_CEC_Vxxxxx_16D.hex    : 16x02 I2C Dual LCD
UBITXV5_CEC_Vxxxxx_16D_S.hex  : _16D with I2C Meter

UBITXV5_CEC_Vxxxxx_NX.hex     : Nextion LCD
UBITXV5_CEC_Vxxxxx_NX_S.hex   : _NX with I2C Meter
so the file would be UBITXV5_CEC_V1.200_16P.HEX in the zip file.

Hope that helps.
