Paul, The sbitx is not a simple rig, it is minimally designed. It has an in-channel dynamic range of 80 db. That means, it needs more than 16 bits of adc resolution. The wm8731 has 24 bit resolution

also, make sure u use an attenuator on ur nanovna,qrp transmitter? so you dont fry something in the ubitx. 73 David ac9xh

I think i meant transceiver,instead of receiver. sorry. 73 David ac9xh

Ashok, 1.Dont try to calibrate the ubitx unless you have a problem.I never did any of the "calibration stuff "others tried.Only thing i did was install n8me software on? my ubitx. took care of the

Curious why you went with the wm8731 codec? I've never used one. What is its claim to fame? That thing looks pretty crazy to me for use in a simple rig.

Hi all, I am new to uBitx and every then and now I am having one question in my mind. For this time can anyone help with alternative method of calibration because the VU2ESE method of calibration

In the first ru, we will probably have 50 basic kits and 150 full systems. I would also mention here that this is a developers' edition. Familiarity with raspberry pi, ability to use command line etc

Hi We use following applications with or withour vcoder dongle 1) Peanut 2) BlueDV Software with USB Dongle 3) Droidstar ( works on IOS/Android) 4) iax DVSwitch on Android /IOS 5) zello (non Ham) but

Awesome! ?Thanks Ashhar Scott

Scott, There is a provision to run any other software (I started with wsjtx) using the last of the mode settings : digital. You can run these additional modes like you would on a conventional radio.

Hi all, I just installed the N8ME firmware with VU3GAO mod and now I need to do calibration. I cannot find any guide to do calibration of uBitx with N8ME firmware. Can anyone help me ? Thanks Ashok

You’re very welcome! I run a 5” on my v3 ubitx. But going to upgrade it to a v5 that I have on my workbench. 73 Mark AJ6CU

Hi Ashhar, Thank you very much for the response.? I understand the timing bit.? My company has been having a rough go of it just getting certain IC stocks to build circuit boards.? We make UPS

After messing around for several hours, I found a post mentioning a 5 inch nextion file made by AJ6CU.? Downloaded that, uploaded with no issues and now I have all the screen populated by the image.

Mike, I am just about wrapping up the sbitx documentation. I will get to uploading the 3d files afterwards. You can switch to 4.915 MHz. It will make it difficult to add a frequency counter unless you

Cool design, I really want to try it. Will probably use BF998 in RX mixers. 5MHz IF may be a problem for US hams, because of the very strong WWV signal right on that frequency. Even the input bandpass

I have recently purchased a ubitx kit (V5) bundle which included a 5 inch nextion display and appropriate case.? I tried programming the nextion tonight and while the 5 inch nextion file seems to

Scott, We will still be giving out the basic kit at a much lower price (about the same as the ubitx). The main board is almost twice the size of ubitx. We had to use much more costlier transmit filter

Hi Ashhar, I too have been anxiously waiting for the sBitx.? I am a bit disappointed that the cost has creeped up but I do understand the problems.? You have to make money. I assume that the $500
