Re: Help: uBitx V3 parallel 4 MHz narrow CW filter and firmware changes?

Gerard,

That code should be wedged into the file ubitx_si5351.ino. The structure of the si5351bx differs slightly than the code you found and variable names are also slightly different. Perhaps this could be set in the setCarrierFreq section as there is already some tests for cwMode?? (There is even a comment out section around line 153 that tests for cwMode.)? I have tried to leave that file alone in my hacking so I am hesitant to give it a try myself.

Not sure whether the change in the if req for v5 and v6? has any impact on the filter code???

The challenge is going to be creating a UX visible control for this setting. This will require mods to the unitx_menu.ino and perlas the ubitx_lcd_* and ubitx_lcd_nextion.ino (and if Nextion, you will need to add mods to the Nextion screens using the Nextion editor). You might also want to add this feature to the? cat_libs.ino file too....??

My recommendation would be to get this working as a compile parameter (#define in? ubix.h) first.? At that point, I shold be able to help you get it working in the various? points in the UX. This would be in uBTIX V2 (see ).??

I would be interested in your final design as I am trying to collect addon cards for the uBITX. (And I am also a member of CWops :-) )

I've not been able to make this work.? Is it possible?

Hi Scott,

I got the original gtk based screen to fit on the DSI screen with another 1920x1080 HDMI-connected monitor.? The one issue I have not yet worked out is limiting the touchscreen input to just the DSI.? The touch screen is not usable in this setup, but the mouse works for both.

The gtk screen is being sized in sbitx_gtk.c around line 3411 in the ui_init function.? I commented out the section that starts with?

#pragma GCC diagnostic push

to and including?

#prmgma pop

Then added two lines after the now commented code:

screen_width = 800
screen_height = 480

This forces the gtk screen to the size of the DSI.? Then I set up the HDMI screen on the left and the DSI screen on the right using the Screen Configuration under Preferences.

This worked for me.? If I start Sbitx without the HDMI monitor connected, it functions just like the original code, with the touch screen working correctly.? This points to the touch driver automatically scaling to the full size of the combined displays.? I am still researching how to limit the touch input to the original DSI screen.

Re: new sBitx software

The current version can be found on github, which you can update based on the description in Install.txt.
If you are not pressed for time, then wait for the uSD card version.
Watch the release, download and use it.
I think there are a few more things that Farhan wants to include, so it will have to wait until it's done.
I do the same :-D

Indeed, RPi4 ethernet has auto-sense, so no need for cross cable, it will automagically swap tx/rx lines.

Help: uBitx V3 parallel 4 MHz narrow CW filter and firmware changes?

#101248

I'd like to improve the CW receive on my uBitx V3, by installing a narrow 4 MHz IF filter in parallel to the 12 MHz one. This gives the radio another receive mode, CWN (Lower and Upper), in addition to the normal ones.
I've found information of PA1FOX on this here: https://zendamateur.com/viewtopic.php?f=30&t=18185&p=209736&hilit=ubitx+filter#p209736

I've got a bag of crystals and the construction of the filter shouldn't give me any problems, but the associated firmware changes are another matter.

For the mounting I thought a couple of header pins in the location as done on the newer versions of the uBitx.

The plan is to drill through the pcb and glue the header pins in, with connections to the IF transformers under the pcb.

The above mentioned thread has the code from PA1FOX, but I'm at a loss as to where to place this in the rest of the code.

I'm using KD8CEC's V1.2 of the firmware, and there are probably some more things that need to be added to get this correct.

Is there anyone who's done this and is able to give some pointers?
Thanks,
Gerard, ZL2GVA

Re: Sm AGC connect uBitx V6 #ubitx-v6

#101246

Bob,

I have that board installed in my v5 in an AmateurRadioKits.in case.? The AGC came with the case.

The Volume High and Ground on the mainboard connector work for the v6.? Volume High and ground is there.? For the 12 volts, you will need to tap into the supply from the fuse.? The trick is where to connect to the IF stages.? The circuits are very similar for all of the uBitx versions, so I you have the instructions for the v4, it should be the same for the v6.

You will need a cross ethernet cable. As both (the pc and the sbitx) want to connect to a hub.

Alternatively, use wifi and use the audio from the remote device (plug in an earphone jack to mute the wifi buzz on the sbitx de).

You could also try a separate powered external speaker.? The earphone jack does not have a noise problem, at least not as bad as the internal speaker.

You could also set up a DHCP server on the PC over the wired card, connect via wifi to the location's internet and share the link.? That may also work for the static IP connection.
