Thanks Mike,  I did not know about General coverage mode.  It seems to step buy .1MHZ  which is what I was trying to do.  Thanks to the others for the WWV ideas but my reference to WWV was an example. 

My changes work as I wanted but I still would like to figure out how to make it display correctly.  I cannot find where to change the data type to unsigned long.

Re: CEC firmware with RadI2Cino board? #ubitx #firmware #radiuno

Jim,

That is a great offer to provide Ian with a free Radi2Cino, it's a shame he hasn't taken you up on it.  Perhaps he doesn't want to have to maintain the code changes either, which is understandable.

I was able to modify Ian's CEC code so it didn't go into transmit immediately.  However, it would still go into transmit if I turned the rotary encoder quickly (???).   Turning it slowly worked properly.  

My current plans are to go with the TFT/Arduino Mega display for my uBITX, I already had all of the hardware laying around, I just haven't gotten it wired together yet.   I've since bought an Icom 7300 and have been spending my radio time playing with it, and putting up antennas, so the UBITX has taken a back burner.

You MUST put the 4.7K resistor between pins 2 and 3 of the Raduino regardless if you are using factory or CEC software to keep it from going into transmit without pressing a CW key.  That's spelled out specifically in the instructions and if you don't have that resistor in place and wired correctly that may well be your problem.

Wish edit was enabled.  The pins 2 and 3 I'm referring to are on the "Digital" plug.  Pin 2 is the A6 analog input for CW keying and pin 3 is 5 volts.  This resistor pulls the A6 pin up to 5 volts which is the key "UP" condition.  If the pull up resistor is NOT installed, that input "floats" and if it gets near zero volts, the software thinks a CW key is installed and is pressed (Key DOWN).

Re: Finding variables in source code

Jack, W8TEE
 

I think we all run into situations where we need to find the definition of a variable or object in a large set of files. The UNIX tool Grep is perfect for doing that. The Grep version I use is not longer available, but I just downloaded and tried this version and it seems to work well:



If you want to change the data type of a variable, use Grep and type in the variable name, supply a search path, and BINGO it finds all occurrences of that string in the directory/subdirectories seach.

Re: Windows Serial Port Problem

Lawrence Macionski <am_fm_radio@...>
 

Windows 10 is the culprit..I also have a RS-HFIQ SDR transceiver and in their forum, there are numerous mentions of WINDOZE 10 blowing up ham radio settings..

Perhaps the main reason everyone has a fast WINDOZE 7- professional or Ultimate version

Re: Different Tuning Steps #ubitx

You'd have to change it in the source code and then compile & load it. I don't think Ian has released the latest source. And it might be (most likely is) more complex than just changing the data type on the variable...depends on how the code is written.

Have to ask Ashhar on that one.  I'm just paraphrasing the instructions that are published on HF Signal's website.  I don't use the A6 line for CW keying after freeing up the Digital pins when we went to the I2C display but lots of people still are.

Re: CEC firmware with RadI2Cino board? #ubitx #firmware #radiuno

The INPUT_PULLUP pin qualifier activates the internal pullup resistors and should produce enough voltage to read logic HIGH on the pin. A closure of a switch (or key) on that pin will pull it to GND, which is probably what is wanted. Given the voltage divider circuit Ashhar uses for keying, the pin qualifier may not be what he wants.

We've discovered something else about the analog inputs.  It appears that the NANO contains only one analog to digital converter (ADC) and it's fed from the analog input pins by a multiplexer.  If that MUX fails the analog inputs quit working or do squirrelly things.  Something else to look out for.

Jack and rest if bit20 group I was 1/2 wrong!


Pull-up resistors

The analog pins also have pull-up resistors, which work identically to pull-up resistors on the digital pins. They are enabled by issuing a command such as:


pinMode(A0, INPUT_PULLUP); // set pull-up on analog pin 0


Be aware however that turning on a pull-up will affect the values reported by analogRead().



***  It is the last line that may cause issues.  Guess if you define a "iINPUT_PULLUP" then you should not use analogRead().

uBitx Version 3 and my homebrewed enclosure complete - Well Almost!! #ubitx

Well, when I first posted about my uBitx being done, I made a mistake and in the title I typed QCX!  DUH!!!  Well, here I am again with my completed uBitx (not QCX).  I only have a few mods left to do, but right now I am having all kinds of issues trying to get the KD8CEC S-Meter modification done using the LM358 chip.  But I have that mod left to do, the TX/RX pop mod and the AGC mod by ND6T (I think that is right) to do.  I have already did the mod and added an RF gain control with a 1K potentiometer.  I created my own bezel for the front of my homebrewed enclosure. I also added a USB male to female adapter so I don't have to remove the cover to update the firmware.  Still need to get the SD card ribbon cable extender to plug into the Nextion display so I won't have to remove the display to update the tft files on the display.

Looks nice!  What case are you using?  May I ask the current draw on receive?

As you have the AVC kit installed, you canuse it for the S-meter and forget about using another chip and such .

Just hook the ubitx  s-meter wire to the AVC board.  It goes to the first pin where the jumper is on the board that sets the delay.  I forget the capacitor number, but it goes on that junction and the resistors for the time delay .

Works fine after you set up the values using the memory manager.
