I will be starting to assemble my uBITX after the case is delivered on 6/1. ?I received the uBITX on 4/18 and have been waiting for the case to delivered from India. The board I received is marked N97014, 2/18, V3(c). ?I need to know what upgrades wil be best to install now. ?Please advise if there are any errors that need to be addressed at this time. ?I would like to know if anyone is using the CCI EB63A amp. ?Please let me know if the online assembly manual can be trusted to be correct. ?I also need advice about installing the firmware, not real up to speed on this. This build will be a learning experience on the software side. Is there a good book that would be recommended as a learning tool for the Raduino firmware. I will be using this radio primarily on 40-80 meters at this time. Any and all advise will be greatly appreciated.
Thanks, buddy3223 KJ4ZSI |

Do yourself a favor and get the stock radio working before you mod anything.? The stock firmware works well out of the box.? Once you are positive the stock rig functions normally you can go crazy.? If you have problems out of the gate it is going to be that much harder to troubleshoot if you have a non standard set up.

The archived assembly instructions are here:??
They were updated and should be accurate.? The only issue you may have that you should take care of is the audio amp chip.? If it has the WX on it then I recommend replacing it with a socket, or just solder a 6-8 volt regulator in the +12v line on the bottom of the board.? The instructions for that are here:?/g/BITX20/message/44125?p=,,,20,0,0,0::Created,,regulator+WX,20,2,0,14340543 That worked well for me.? Don't worry about any firmware changes or calibration changes until you have assembled it and used it a bit.? Also, check out ubitx.net for news and information. Daniel, W2DLC |

Most of the talk here about mods has been with regard to getting more power out on the upper bands,

Works, but only a watt or so on 10m. If your interest is 80m and 40m,? you can ignore all that fuss. Get it going with no mods initially. Should do fine on the air as is. Jerry On Thu, May 31, 2018 at 11:19 am, Daniel Conklin wrote: The archived assembly instructions are here:?? |

To learn about the software you may want to get one of the nano processors and a display, and maybe one of the rotary encoders.? They are not very expensive, only about 2 or 3 dollars shipped from China.? You can hook them together and play with the software and see how to load and modify it without things being hooked to the uBITX.?? Lots of things on youtube about the nano and uno processors.They use the same processor, just different board layouts for the most part. de ku4pt On Thu, May 31, 2018 at 1:50 PM, <hotrod541@...> wrote: I will be starting to assemble my uBITX after the case is delivered on 6/1.?
