Raduino offset

Richard VA3NDO
 

Hello to group.
I have built and calibrated a homebrew Raduino. Works all OK
I would like to built it into a homebrew TXR I am constructing.
My  TXR has an IF of 72 Mhz, not 45 Mhz as per the Raduino.

I am not an Arduino expert, and I cannot find where to change the IF offset in the sketch.
Can any Arduino gurus point me in the right direction?

Many thanks

Richard  VA3NDO

Using Eagle cad. Paid for license. This is a very potent piece of software. For professional use.
Yes, for hobby application KiCad is fine. The are a couple of free cad software available on the
net.

I used the pcb express free tool for a while. Then I switched to kicad. It has a bit of a learning discipline (you cant layout unless you have drawn out the schematic first, etc.). My only complain about it is the component libraries suck. In each version they try fixing and it breaks the earlier version and makes it even worse.
I learn this useful tool from OM Bhatnagar, he is on this group.

I used simple free software, where you have to connect all the tracks manually and place the components yourself.
That’s what I used to feed my Ubitx power.
Some software are only in demonstration and do not allow to print or save.
With a little time, I focused on Kicad.
It is true that this software is not constrained and it is free.
At first, I thought it was fantastic software and making a pcb would be simple.
So I watched several videos....
I thought we could have imported a diagram from a pdf for example, and not possible.
So we have to recreate everything manually, the diagram, then choose the components.
After that, it remains to create the PCB. I told myself, that with all the informations it will propose me one, that to rigor I could modify.
No, there too none of that.
You must also choose everything manually.  Only positive thing, you have a 3d view of your circuit.
I may be wrong, but I have this observation.

Also know if you can control the output power to the V6 from any menu on the radio. Because what I have read this is not possible.

Gary,
Is it possible to remove the Raduino and display from the case and connect to the USB port on your computer without the mainboard?  The Raduino should powerup and the display should show the normal frequency screen.

If this does not work, then my next thought is the display or the Raduino board as the digi board supplier suggested.  If it does work, then there may be a wiring issue in the case.

This is really a head-scratcher.  I cannot see why the one Nano works and the 3 others do not.  Are you sure that the Arduino programs are the same?  When I read your statements it reads like you reprogrammed the original Nano with the files (sketch) that are the same as the 3 new Nano programs.

There is one other thing that you could try: reprogram one of the new Nanos with KD8CEC software that works with the 16x2 display.  That would be in this archive:
https://github.com/phdlee/ubitx/releases/tag/v1.20
The correct file would be in the uBITXV234 folder.  The file for the parallel display is UBITX_CEC_V1.200_16P.hex
you will need the Xloader program to load the hex file.

Thanks yes I did.  I took the digi board completely out of the loop. If I put the original nano in the radio acts as a normal v 4 ubitx. I can't figure out why these replacements won't work?

Somewhere I read that after some changes were made, the V6 had to be turned off and back on for the changes to take effect. I think there was a few seconds delay in turning it back on required (in the commentary), IF I remember correctly.

Perhaps someone here can clarify this or report if there is any value to this suggestion.

Re: #v6 connect ubitx V6 and Xiegu XPA125B #v6

You would need to key the V6 on the freq you want to operate long enough for the tuner to go through the tune cycle. Otherwise, there should be no problem using it with the V6...

I am getting ready to build the N7DDC tuner which should require nearly the same thing. Keying it on SSB would not work unless you had a tone going into the microphone.


Xiegu also offers a connection hub for the G90 which may be of some use...

Re: Kicad files

Sometimes you see a Hotwater-8 or an HW7 (the -8 is more common) at a big hamfest going for $50-$125, depending on condition. They are usually bought for nostalgic purposes since in their heyday, they were what put many beginners on the air...

The V6 beats the pants off the Hotwater QRP radios. However, the Heathkit radios were pretty much king of hill when they first came out because of their popularity. Good design for that era but today, they are museum pieces. To say so, though, brings out the oldtimer's ire in many hams.

Re: Calibrated now no receive.. Ubitx V6

Jerry,

Great info and thanks for the input. In hindsight I added the zeros to match the info kindly provided by Reed N. I actually just turned on the Ubitx V6 and the additional zeros were not there...Had to check. It was a blurry day trying to get it calculated after hours of trying and a good learning curve albeit frustrating.

Re: Calibrated now no receive.. Ubitx V6

Jerry Gaffke
 

Regarding calibration on the uBItx, a few recent posts:

https://groups.io/g/BITX20/message/83191
https://groups.io/g/BITX20/message/83197
https://groups.io/g/BITX20/message/83225

In that last reference, Vic's method of matching a known audio tone
probably is more accurate than trying to hear a beat down near 0 hz.
Assuming you can exactly match the audio tones, the resulting calibration
should be exact as well.  The math works.

Not obvious to me why the final line for setting CLK0 is there:

All three clocks should be updated whenever the cal value is changed.
I tend to do this explicitly where the call to si5351_set_calibration() is made,
but putting all three calls under si5351bx_setfreq() is not a bad idea.
Updating only one clock there IS a bad idea, and suggests to me why
so many are still having to make multiple passes when calibrating their uBitx.
