UBitx HF

Tranceiver kit 

My uBitx story

​

This started June 2018 when a work college showed me a radio kit he had ordered. 

​

 It was the Ubitx and it blew me away what it could do for such a low price.  That night on the net I read of other ‘s building it with lots of mods and a touch colour screen.  My god this is amazing.  The next night I ordered one from HF signals site.

​

Funny thing is I still had a Bitx20 to finish building,  this project has been on going for 3 year.

Wait seemed to take for ever but it gave me time to think, what this radio going to look like.  Back in 1994 I wanted to make a foxhunting receive for HF to 6M.    

​

This project only got to the halfway point when I gave up.  This gave me the idea of the format of the design.  The radio would slide into a amo box for portable work.  

​

As this is a transceiver it has heat issues and plugs and sockets cant be mounted on the back.  I don't like the idea of stuff coming out the front so the side it will be.

My thinking was also influenced by my other new hobby, 3D printing.  This has opened up a whole new world of what I can do.

​

Also I had a dream of upgrading my uBit with a touch screen and KD8CEC firmware.

​

​

So I did this first drawing while a bit borded.  

I knew the firmware allowed the radio to go down to 160m and 473kHz but at the time I had no idea it worked so well down there.

​

So the project has started a bit backwards.  I will make the chassis and case and work out the insides later.  My wish list is my guide.

My 3D printing Kit.

​

I had a rough start with 3D printing, this was a blessing I know now.  I had to learn how to unbrick my Tevo Tranatula 3D printer after a failed firmware upgrade.  this took many weeks of cursing Win10 (hello windows 7).      I  ended up buying a new Anycubic I3 printer just to get printing.  After many weeks  of learning Fusion 360 with youtube my guide (Fusion 360 or Die Trying) , I became more confer-dent on what I could make and design.  I made lots of junk on my new printer, mainly for my daughter.

​

One day I cracked the Tevo and unbricked it using my Mac.  New boot loader and firmware and the TEVO was alive again.  The TEVO was nearly rebuilt for ABS printing.    So all my Ubitx printing is in ABS as I want it to survive in the hot sun.  By the way I used the Anycubic to make parts for my TEVO, the chicken or the egg problem solved :)

Now that I now had become dangerous with Fusion 360 I could spend many hours drawing what bits I needed.

The front panel came first with speaker grill and VFO knob.  While all this was happening I would transport the uBitx in its little lunch box to work and back and play ham radio on it.  Its just sit there with no case and performed well.   It only last 2 weeks with the two line LCD, I did the firmware upgrade to the nano, programed the Chinese version of the Nextion screen plugged it all in.  It didn't got that smooth, lots of learning how to do stuff and getting my computer to recognize the USB serial chip etc :(

​

I used the Ubitx lots as a shortwave receiver listening to aircraft and Radio New Zealand International.
