NEED HELP

Laddie
 

HI, I have in hand ubitx and universal da maroon enclosure.
Nether the $129 radio/board kit nor the $43 enclosure came with instruction only a parts list.
I am flying blind PLEASE HELP! Assembly manual with photos or video PLEASE. Thanks Laddie

I don't know anything about that case but the µBITX instructions are available from the same place you most likely bought it http://www.hfsignals.com/index.php/ubitx-wire-up/

Hi! Let me say, its gonna be ok.  On YouTube is vast collection of videos that can assist in your build. I am also providing some pictures and schematics.

Gives an overall demo of completed radio...I recommend Neo the nomad videos on YouTube.

Happy building!

I admit building into that case takes some thought in merging instructions.  check the ubitx.com website for useful info, more than I had. This URL is hosted by Sunil the case builder. Many little things to figure out, pretend this is more homebrew than kit. You have options but take time to figure Sunil's intent. Even getting the raduino cables correct may require study of pictures.

Looks like I installed more headers than are in the kit. no biggie I'll just remove them and direct solder.
where do the analog and digital cables go? There is only one connector on the main board.

yep this is a key step, the digital cable goes onto raduino while analog goes on the board.  i had to stare at one of Sunil's assembly pictures for a long time to figure out which is which,  on mine the violet wire goes onto the left side for both connectors when facing front of the rig.  (this is using the optional(?) cable kit from Sunil.  carefully examine your stash - you really don't want to solder these type of connectors as disassembly need happens. 

I imagine you can find many pictures (not mine) of builders on the web.

very few photos and videos are closed cabinets

Where does the led connect to? In photos it seems to connect to the underside of the main board.

My case came with several pages of 'instruction.'  one of these conveys the 3 places the LED solders to for the PTT illumination.  I am remembering this thing to be way too bright, so I used larger value resistors (maybe 3 or 4X) to feed the LED. 

I do remember a video that was or is posted to ubitx.com - I found it after I am had assembled but it was very useful as I remember.  Then it was on the front page. 

A key assembly hint -- remove the front panel to allow easy mounting of the raduino and other things into the main board. 

Use your ohm-meter so that you properly connect to the SO239 connector.  Yes find which side is ground and of course this goes to outside of the coax (hint the 4 mounting holes are ground). 

When you get assembled and power up, note as many discovered you won't like the display.  There is a trimmer pot on the backside of raduino, slowly adjust it until you see the nice display.  then note you push the main tuning knob to go thru the various menus (this may not be explained anywhere?)

That 4.7k resistor you install allows straight key CW.  It takes a moment to engage into transmit - so at first it will be strange - but once you adapt to its timing it does CW quite well. 

I will stop answering questions you have not asked yet -- hang in there and enjoy the build, pretend its a puzzle!
