Re: Are all the Bitx version fundamentally the same?

Eli,

Have you tried the "Fake It" setting in the WSJT-X setup?  It adjusts the radio frequency to allow for a wider passband.  An example would be moving the received (and transmit) frequency to allow get around the narrow SSB filter.  Opens up using frequencies above 2.8KHz or so.

A good and detailed explanation of the steps to use FT8 (or other) digital modes with the µBITX

Eli,

I have a a Signalink USB & I just came across this video on YouTube: https://youtu.be/dXha5UynvkE. 
Do you think if I made this cable for my Signalink interface & used a usb cable from the PC to the uBitx that it woul work? I don’t think I would need any other cables, would I?

What type of USB connection is on the uBitx v6, is the normal USB connector?

I know I’m throwing quite a few questions at you. I really do appreciate taking the time to help me out. Thank you.

Robert, Ag6lk

Robert,
This is how I set up for FT8. I haven't tried much else. All of this is on a windows PC...although I have a rasperry Pi I may switch to.

I am doing the following:
1. Installed WSJT-X- https://www.physics.princeton.edu/pulsar/k1jt/wsjtx.html
2. Installed a timesynctool- https://forums.qrz.com/index.php?threads/wsjt-x-and-setting-windows-10-clock-seconds.592212/
3. Connect uBITX to PC via USB cable
   3a. Check Device Manager for COM port
4. Connect uBITX to PC via USB Sound Card- uBITX Mic to PC Earphone/uBITX speaker (front panel) to PC Mic
  4a. I had to "customize" the Audio cable from the USB soundcard to uBITX- https://groups.io/g/BITX20/message/84452
5. Turn On uBITX (with antenna connected)
6. Check Settings (configuration) in WSJT-X-
  6.a Radio
    Rig: Yaesu FT-817
    Serial Port: COM8 (based on step 3, not that this can change if you plug in to a USB hub instead)
     Baud: 38400
     Data Bits, Stop Bits, Handshake- All Default
     PTT Method; CAT
     Mode: USB
    Split Operation: Rig
    PTT method: CAT
  6b. Audio
   Input: USB Sound (step 4)
   Speakers: USB Sound  (step 4)
7. Cross fingers....

Actually, this worked well. WSJT is doing the PTT no trouble. I probably could have used the sound ports on my PC as well, but I had the USB device lying around, and could limit the sounds going to it while still hearing my PC through regular audio.

Contact me if you need more information.

Eli

While we are on the subject of USB cables, be careful of those meant only for charging.

Many USB cables these days save $0.05 worth of copper wire by not including the data wires,
just power and ground wires.  These cables often provided free when you buy some electronic device.

More than once, I've spent hours chasing trouble when trying to download to a Nano
only to find that I have grabbed the wrong cable, which subsequently gets thrown in the trash.
Given the non-informative error messages you get from the Arduino-IDE, it's very easy to get hung up on this.

Thank you for the corrections.  I did get the mini and micro mixed up.  I guess the best bet is to wait for the Nano to be delivered and then match the connector on the board.

Hopefully, you have not ordered the cables yet.

I will delete the message that is in error so others are not confused.

Nice set up.

How did you connect the ATU antenna feeds to the uBITx?

I have older Nano boards that have the Mini-USB connector, but the
latest purchases all have the Micro-USB connector.  While this does
make the Arduino use same cables as cell phones, it also adds to the
confusion.  USB-Mini cables are getting more and more difficult to
find and purchase.

A number of posters on this site have had success with a direct connection to a USB sound dongle.  I had RF and Groundloop issues, which is why I added the EasyDigi along with clamp-on ferrites to block the RF.

Thanks Evan - will do the checks!

Rafael,

The code you provided looks correct, and the TXA output should be off
when one of the lower bands is selected.  Can you verify that the TXA
signal on the R151 / C153 junction is close to zero volts (below 0.3
volts)?  If so, then I would suspect that Q17 is shorted.  If it is
always high, then you may have a Nano issue.  Then there is always a
possibility that a solder bridge or short is in the signal line from
the Raduino to the Mainboard.  Verify that the Raduino is plugged in
properly.

Hi Evan,

Thanks!

It is the v6.  I changed the firmware - I double checked the code I'm
using, and " digitalWrite(PIN_TX_LPF_A, 0);" is there in the lower bands.
https://github.com/DigitalHERMES/ubitxv6/blob/master/tuner.cpp

Still, I can measure KA1 is on.

Rafael,

The answer depends on your mainboard version.  For a v6 board, the
answer is no.

Have you changed the firmware in the Nano replacing the stock firmware?

We will need a little more detail to answer your question.

It is a switching supply.  Switchers can cause noise in the HF range.  If you have purchased one, can you comment on the noise generated, if any?

Hi Eli,

im going to have a V6 here pretty so also, I hope. Can you explain in detail, ( I’m a newbie ), how you have your V6 set up for digital? How are you activating the PTT?

Thanks, 73

Re: uBitX v 0.20

Robert AG6LK
 

Hello all,

Going on same line as Lals’ question, has anyone put a 3.5” Nextion enhanced display in a V6? I was wondering if it will fit in or what mods I would have to do for the stock case. I also am wondering how to wire it up, since the electrical board, ( I’m not actually sure what the name is), has to fit in the connection slot on the motherboard. Any suggestions would be greatly appreciated. Sorry Lal  if I took over your question.

Thank’s in advance, 73

Robert, Ag6lk

Re: Is this the correct Display and Nano

Max
 

Ok thanks. I already have a bunch of USB to TTL converters but it will get used for something.

I also meant to ask, how much larger of a display can be fitted into the factory case?

Thanks, Max KG4PID

Both products will work fine. You dont need the USB adapter for this upgrade, but maybe it has other uses somewhere. One might save a dollar or two buying a screen alone.

The Nano with pins unattached is exactly right.
