uBITX Wire Up Drawing error

Philip
 

The wire up drawing has an error regarding the volume control connections. It shows the orange wire as being Vol_high. And the yellow wire as being Vol_mid, going to the wiper.
The orange wire is in fact the Vol_mid, and should go to the wiper. And yellow to the hot end.
The pictures are correct.

Does anyone have a complete parts list for the ubitx?  I am looking for the values of the audio pot, especially, but also a physical wiring diagram of the connectors.

Hi everybody

You may be interested in how uBITx.net is going.

To date in February 2018, there have been 170,000 page hits, with 14220
visits by 8214 unique visitors.  Together, all those 8000+ uBITx fans
have shifted 14Gb of data! This shows just how big the interest is in
the uBITx.  I host around 25 sites, and this is now our second most
popular site.

I am still catching up with reading new emails on the list posted during
the last few days.  I have been otherwise occupied with a visit by
Eugeny UA3AHM and time out at the saltmine.

Since the site launch less than a month ago,  a total of 68 news stories
have been posted.  There will be a few more posted today. These stories
are running about 3 per day, drawn primarily from the approx. 100 email
postings a day on the BITX20 email list (i.e. 3% of all emails to the
list are "news worthy").  This is a pretty interesting statistic in itself.

I am still gob-smacked by the extent of hacking already going on with
the uBITx ...  eclipsing a year's worth of hacking on the BITX40. There
are already three software variants available - each with unique
features.   Clearly, Ashhar Farhan has a tiger by the tail, as he has
two months of back orders of the uBITx to clear before shipping ex stock.

Hopefully, ubitx.net is filling a helpful niche in the ecosystem for the
uBITx.  It's purpose is to document and categorise that which is of
enduring value from the BITX20 list about the uBITx. I have not had the

Re: #ubitx replaced Arduino Nano gives a lot of I2C interference during reception #ubitx

I use 0.01uF on the encoder and encoder switch.

1000pF would probably work too?

Sarma,

Thank you for the suggestions. My problem has been solved with the exchange of the nano (now on headers as I have room).

I have also used screened cable to the encoder and had to decouple the push button at the nano due to rfi on Tx sometimes triggering the menu.

I might also decouple the encoder.

What maximum values capacitors can you use for decoupling?

I too use Diptrace. Both for hobby and work.
Easy to use and has 3D output. You can also order your PCBs from inside Diptrace at a relatively low cost
and the boards are made in the USA. You don't have to wait for shipping from thousands of miles away.

There may also be algorithm issues with the keyer in the stock firmware.
Updated firmware from Jim Sheldon or Ian Lee as posted to this group could help.
Or use an external electronic keyer.

Re: uBITX working, question about power, PTT pop, LOUD headphone output #ubitx

Jerry Gaffke
 

The problem with CW on the stock uBitx is not enough pins into the Raduino to do 
everything we want it to do.  The uBitx uses a single pin for hand key, paddle dot, and paddle dash,
those all drive that one pin through a resistor network, the Nano reads an analog voltage and decides
which is happening.  Contact resistance can quickly get in the way of this scheme.


Here's the code, down in ubitx_keyer.ino  from  https://github.com/afarhan/ubitx
###################################
//reads the analog keyer pin and reports the paddle
byte getPaddle(){
  int paddle = analogRead(ANALOG_KEYER);
 
  if (paddle > 800)         // above 4v is up
    return 0;
 
  if (paddle > 600)    // 4-3v is dot
    return PADDLE_DASH;
  else if (paddle > 300)    //1-2v is dash
    return PADDLE_DOT;
  else if (paddle > 50)
    return PADDLE_BOTH;     //both are between 1 and 2v
  else
    return PADDLE_STRAIGHT; //less than 1v is the straight key
}
###########################


Here's three possible solutions:

There has been new firmware developed that frees up digital pins by moving from the
parallel LCD display to an i2c version of the LCD, so can use separate digital lines for paddle and handkey.
Perhaps someone else here can recommend a specific firmware version that works well for CW use.

Use a single digital pin, the firmware treating it as a hand key, could be driven from an electronic keyer.
But I believe the pin will have to be moved, as A6 is analog only.

Or use the stock firmware, but drive the single analog line with a small circuit board using 2n7000 FET's,
taking in separate digital lines from your paddle or hand key.

Hi,
got my transceiver the other day. It is now built in a metal box and seems to receive well although there is no AGC I guess?
Operating CW is difficult. Have operated CW for decades but now I don't want to try it with uBitx because I get keying errors.
Or the rig makes them, not me.

What do you suggest? There must be a s/w bug which makes the errors, strange delays, too short or missing dots.
