You need to run Ubitx Manager on your PC. Philip G7JUR

Hello everybody, I just installed ND6Ts AGC Circuit and wanted to turn on the S-Meter in the firmware according to the instructions on KD8CECs Homepage. However I just can't get it on the display.

I believe there is an nonlinearity problem on some of the newer V4 uBitx radios (the one with transistors in the final audio amp). Two of my radios had this problem. The problem is that the two diodes

The uBitx is prone to overload if there are strong signals. I have done some tests with an analog AGC detector and different FET shunts on the RX line after the relay before the first mixer. I used a

Bill, The trace cut is shown under the manual gain control installation ( http://www.nd6t.com/uBITX/RF%20Gain.htm ). You are correct with the destinations but that trace between them needs to be

I'd like to build a uBitx completely from scratch. I've been looking at the circuit diagram and I cant figure out how to wire up the raduino. How would one make a raduino from scratch and wire it to a

Between the microR2 and the miniR2, yes, they listen easy. The most noticeable property is listening to a pile up, rather than a mis of heterodynes and noise you hear what sounds like a busy

I installed my 12v auxiliary cooling fan in my uBITX earlier today to replace the unseemly box fan I had propped up over my open cased radio.? After I installed it and dialed in the temps I fired up

Farhan has posted Gerbers for Raduino. I guess one can order few boards from China for their personal use. I have also uploaded a homebrew friendly single sided board for making PCB by toner transfer.

My surprising success with the click kit has emboldened me to go ahead and try building Kees ND6T AGC kit. ?I want to build a simple version without any extra controls and I am confused as to the

Very nice!?? I ordered my fathers day present yesterday ( https://smile.amazon.com/gp/product/B0778KCLS7/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 ). What are you using to generate the artwork &

the contemporary method of rating the goodness of a receiver is now down to a single test : reciprocal mixing dynamic range. simply stated, you have very low distortion crystal oscillator amplified to

Hello. How are you? Mr. I need the program of the mini arduino of my bitx40. since the one that I had was burned and I had to change it. your help is appreciated

RoughTranslation: Hello, I need the raduino program for bitx40, I had to change it for a new one.

just use your phone's camera. I even saw an app that will decode the resistors' colour codes - f

Whoops, sorry, Jim. I had already replied to Jack before I saw your post. I'll take further comments to a separate post.

Jack, I ordered one because of the post here. I have a crappy little USB microscope, but it's a bitch to use for electronics. This was affordable, so I ordered it. It should be here in a couple of

Dennis, they are in short supply. Somebody might be willing to let one go for you, however I have created a circuit board design that isn’t the same size but could be used. I could send you the

So sorry that your postal system is so destructive, maybe you should contact them instead of this group! Being a retired Electronic service engineer and college lecturer I suggest that instead of
