For your conversion consideration,
BNC female panel mount with 0.72" holes on center are not common but do exist.

Re: uBitX V6 brightness control?

Yes, find the resistor to the LED that provides the driving current for the lighting, and then increase its resistance.

Re: plugging mic in causes the ubitx V6 to go into transmit mode

Gordon Gibby
 

So, start with the basics. Read the voltage on the push to talk pin of the jack, and see what happens to it when you plug that mic in.

If it goes to zero, you are shorting it out somehow.

Proceed methodically and systematically from that point to find out where it got shorted to ground.  

This is regular old ham radio, a chance to learn and practice techniques of figuring things out

I used to buy these from Oak Hills Research, however with Marshal Em's passing you can not order from OHR.

It is just a plate with 4 screw holes spaced to match an SO-239 bulkhead fitting and a d-hole in the middle to fit a BNC bulkhead.
There are other ways to handle this conversion but boy does that little plate make it easy.

If you have a machinist friend it would be fairly easy for him/her to 
make a D-hole Punch for thin aluminum plate.  Remember old bolt-
driven chassis punches.  Same thing works for punching D-holes.

Re: Ver3 to CEC

Evan Hand
 

Rajesh,
First off, did you follow the suggestions in this message?
https://groups.io/g/BITX20/message/80271

NOTE: Please ignore the typo Arduion, it should have been Arduino.

There is only one file that needs to be loaded into the v3 uBITX Nano with the stock display using the Xloader.  For your situation that would be:
UBITX_CEC_V1.200_16P.hex

The tft files are used by the Nextion display, that you do not have.  They are not loaded with Xloader, rather they are transferred to the Nextion through a microSD card.  

From what I can understand from your messages, you are not seeing the backlight turn on in the stock display.  That is a hardware issue and has nothing to do with software.  If your setup is working EXCEPT for the backlight, you should be able to read text on the display if you shine a light on it at an angle.  You can adjust the contrast with the P2 control on the Arduino.

I believe that you are at the point that the best option would be to find a local club or ham that can help.  I am running out of suggestions for you to be described over the messages board.

Good luck

Re: WSPR no TX #ubitx-help #digital

Vic WA4THR
 

Evan, the CEC firmware allows WSPR in beacon mode for transmitting, but not decoding. You use the Memory Manager program to set your location (you can set 4 different locations), and frequency (3 available), and to set the code for your call and power level. Then you enter the WSPR mode by pushing the tuning knob and selecting WSPR, then select your  location choice and frequency. The 110 second beacon is then initiated  at the top of an even minute by looking at your watch and pressing the PTT. It works fantastic and allows you to get reception reports back on your smart phone or on your computer when you get home with only the rig, a portable power supply, and portable antenna. I have used it as a demo at hamfests, at the beach, and to test different portable antenna options. A very clever addition by Dr. Lee built in to all the later versions of his software.

But still the display does not light up.
