Remove the // in the top entry that start with //xstr

I think the second like was already commented out.

Joe,

I think I found where you commented out the max Frequency.  In the pre-initialize events "vis tDecode1,0" . changed that to vis tDecode,1 but had no impact....

Was there some reason you decided not to display the frequency?

Re: uBITX will not turn on

The raduino turns on when powered directly. My version is 5.1. I found this interesting as all the troubleshooting guides I've found were for versions 3 and 4. Is v5.1 very new? Could I be experiencing an issue with this version not documented in the previous versions?

I still need to figure out if I need another ground wire on the antenna in addition to the black and brown wires and where that would attach to (as seen in the video).

Ok, definitely need to invest in that tutorial...   One last question, that vis tDecode1,0 was irrelevant?

Yes I would set that back to what it was. It would be great if Ian CEC would come to our rescue on some of these tasks but he’s busy with more toys for us to play with.

That's good news about the raduino. Is it possible to get a pic or two of the build so we can get a better idea of the wiring?

Doug and Nigel, yes so I'm trying to copy at least Nigel, and many others (which is good news).

As suggested, Win10 reassigned the cat com port from COM7 to COM13 when I put the cat usb cable into the usb hub.  No problems, I just change the com port in fldigi rig device control to COM13...but no.  While COM13 shows up in the dropdown list, and I can select it, nothing happens. After I do hit the save button  (which gets a thin dash outline, and just sits there), or click Save Config on the tab, no changes take effect. After I close fldig, and open it up, there are no changes in config. Hamlib is unchecked, and com13 is not selected. 

So it seems like I can't save the config, or there is some reason why I can't really select COM13 with the usb hub?  Is there something else I am doing?

Joe,

Reset everything from the original, made the one change you suggested and it "worked". Looks like some background color issues and positioning is not right (and perhaps the font is too small). 

Is there a reason why you originally commented it out?

I didn’t feel like I needed it and yes between stretching the background out which appears to be lines or columns, the frequency text didn’t look too appealing. I suppose you can make the font bigger. The background and the scope data have a weird interlaced relationship with one another if you know what I mean.

PA Power wire up?

Steven
 

 Hi all,
 
First post here. I am reviewing the instructions for the BitX40 and am unclear about one thing. How is the PA Power connection wired up? From the diagram it appears like it is a separate power plug. In the description it is unclear where the brown and black wires go to.
 
thanks

Re: single usb for cat control & sound card #cat #ubitx #ubitx-help #arduino

okay, so after a day (almost) of back and fourth, it was clear to me that only COM7 was loved by the uBITX cat control.  I finally threw in the towel (I didn't even know I had a towel!) and deep in the advanced device manager setting you can manually assign a comport to a device.  I set it back to COM7, got an error that it was in use already, said darn the torpedoes, did it anyway, reboot, reset fldigi device to COM7, and presto.

Both usb sound dongle and usb cat control now work under 10Win.  Just to push the line, I added one more little usb bluetooth device for my logitech mouse and keyboard.  And now all four functions work on one usb hub: sound card, ubix cat control, mouse, keyboard. Whew!  What a night mare. Who would want to figure this stuff out??

So thanks Nigel and Doug.

Nigel, I too think the arduno should not be powered by the usb cat control.  So you "cut the red wire".  Did it make any difference, actually? Should I do that as well?

Now, on to the Atomic Pi (a rasberry pi clone, sort of) and Lubuntu.  My goal is to have a dedicated computer just for wsjtx (WSPRnet!!) and fldigi, then I will build a new enclosure containing BOTH the uBIX and the Atomic Pi and the usb hub. Then I will have a total integrated portable package. And I will free my old win10 laptop from uBIX bondage.

I know nothing about lunix, or Lubuntu. Zip. Nada. I'm not even sure I'm spelling them right.  But I did get Lunbutu (the OS) installed and working on the AtomicPi. and I got Fldigi installed, but not working due to the Atomic Pi having only USB port so I couldn't get control and sound working.  So now you see why I'm going to take the usb hub, with uBIX, sound, mouse, keyboard from the old Win10 laptop, to the new cool AtomicPi.

I'm sure with a few hundreds of hours of tinkering, messing, trying, failing, errors, redos, and a little help, it might work. If not, I'm only out $38, and a few hundred hours. ahahah. 

Thanks you!!!!

Don,

I 'cut the red wire' because I had already removed the Raduino 5v regulator and modified my v3 boards audio to have a 5v supply (and the Raduino, USB hub etc) separately supplied from a small radio control 3A uBEC (you can see it, plus a small buss for 5v & GND feeds) on the left most side of the board/enclosure.
I also use the Win10 laptop for other things and when the laptop is on, the Raduino was powered up via USB - hence disconnecting the 5v feed from the USB from the computer side.
i also noticed that with both 5v feeds connected, sometimes it would cause the uBitx to reload/restart when interconnecting the USB cable.
I have no sign of any interference from the uBEC or the hub etc, so I'd say yes, cut the red wire!

Only downside is that when updating firmware, you have to have the rig powered up (as no power is supplied to the hub/Raduino via the computer USB port).

The upside is that I don't have to open the case to do firmware updates!

So now I'm stuck on getting uBITX cat control working on the AtomicPi in Lubunto.  The audio works great, I get decodes!! So good there. I have tried every option on the Device dropdown list. No love. I'm sure the problem is due to my total ignorance of how to configure ports, devices, or anything in lunix world...ahhhhhh.....
But I can't configure the rig tab to control the uBITX for the important job of actually TXing.

Hi guys!
Yeah we are pretty confident we have a fix for the v4 issue. 

As for driving sunil's s-meter display we currently need to get one to see how to properly wire it up.  It should work acceptable unless it's very current hungry which will cause the decay on the agc to be very fast which may not be desired. 

Does anyone have one they could ship (paid for of course) for quick R&D else I will get one on order. Though I can't seem to find where to get just the meter.

QSL - I will have to read out of general interest on the v4 solution with ND6T.  honestly I like the VK3YE solution, its a third option for AGC but a road less traveled here.  as for the v3 and v4 community - I am hoping someone will kit solutions for a fix.  I have harmonic spurs addressed, now I do have some shielded inductors to try to see what they contribute.

Re: Nextion 5/Enhanced for KD8CEC 1.2?

Joe,

If you change the line:

from
xstr 5,350,90,18,0,WHITE,10565,0,1,1,sTemp0.txt
 
to:
xstr 20,365,90,22,2,sys1,7,0,1,1,sTemp0.txt

You get rid of the gray background and the text field is positioned correctly. There are still a couple problems:
1. The spectrum has a gap on the far right. It is just too small horizontally for the scale of the spectrum box.
2. The spectrum does not appear to be vertically scaled (same physical height as the 3.2 screen)
3. Cosmetically, there is a gap in the upper left corner of the box that encloses the spectrum.
4. The sample rate of the frequency is probably too fast. Too fix, you have to slow the timer interval way down and then the spectrum lags in its update. Probably just leave it at the existing rate...
5. Not sure whether it is a problem or not, but on the 5" you get definite histrograms on the spectrum while on the 3.2 it looks like a more contiuous graph. Suspect that this is one of those things where having more resolution doesn't help. :-)

I am going to spend time on 1-3 and ignore 4-5. Any pointers there would be appreciated.

Ah...good info. Thanks!  I also added a BEC for some the 5v needs (plus a usb charge port), and a big dc-Dc buck converter for the 12v board. Now I can power it up with anything (almost) and the finals are at “line” power, and the rest is 12/5 as needed. Even made a tap for the antenna runner led in the meter. 

Such fun. 

Now I just have to get my atomic pi and fldigi/wsjtx working....gur. 

Thanks agIn!!

Re: Bitx40 Noob #bitx40help#smoke

Ok I found the problem, well I am 99% sure I found the problem I just need to test it. For some or the other reason the arduino nano died, but its pins are "upside down" the protrude from the top of the board and not via the bottom of the board "like normal". So when I have been connecting the standard arduino nano (which comes with the pins pre soldered) I was then installing it upside down.

Attached pictures for reference, I will swap things around and test then confirm. I am just following this up in case someone else comes across this problem too!

Re: Bitx40 Noob #bitx40help#smoke

I believe you are correct,the Bank is indeed fitted upside down and it's vital to purchase the bank without the pins soldered and so you can orientate it correctly.It required the pins to be soldered but that is easy with a fine tipped soldering iron.

I have used the AD8703 to roughly estimate the output levels of oscillators (I have no oscilloscope), like dds and si570. If genuine it should be linear up above 0dbm, depending on the frequency. In any case if the hardware is fine, a firmware change would likely correct it.

Yip tested and it works, need to de solder and redo the pins but as a proof of concept it seems to be working. Now to get it into my Bitx and generate some RF.
