This looks like a BFO adjustment issue to me. I believe that the carrier is in the waterfall as well. Another possibility is the balanced mixer with T7 and D5 may have issues. You could have a

Hi, may I have a copy oF list component as well please???? Thank

uBitx version ? Raj

Hello everyone! I would like to share with you some informations, I installed a new Inverted V antenna for 20m and I discovered that my uBitx is transmitting some "shadow" signal along the center

here some pics... for your help. tnx in advance danilo in3izq

Paul, my concern with anything setup for 13.56MHz is the bias levels for the amp, simply because there are no applications I am aware of that call for linear operation in that ISM band! -Justin N2TOH

Lee, I've been retired 10 years now, all I do is climb the walls looking for stuff to do! -Justin N2TOH

They were selling the fully assembled Antuinos for $80 at FDIM. =Vic=

Upload a crisp photo on the internal main board. let us see.

hello, i'm in3izq danilo from italy. Have buy by friend an ubitx , when i on her look at display ubitx 0.20. can i upgrade at version 3 or 4 ? are a newbie and work a little

Obviously

Obvious that only Farhan can bring out the price at the due time

I see the Antuino was officially released at FDIM. Anyone know how much it will be to the rest of us?

Update: it works now. The problem was a cold solder joint on the batt(-) pin of the barrel connector. I should have looked more closely before posting! Bruce w8bh.net

Jack No I was merely be philosophical and maybe slightly trivial. In spite of my call Dayton is about 10 hours away by car, but I should consider making the trip. Nice there are wares to consider,

This is right where I'm at now. Sooooo many configuration tips and absolutely none of them are the same. I especially loved the one about setting BFO by tuning to static till it sounded "good".

There was so much trial, error, fumble, confusion and general stupidity in my process that it is a model of what not to do. I distill till the process: 1) express the 10mhz freq error as a percent

Farhan, I just saw your updated schematic on github. Maybe the only issue is a faulty barrel connector. - Bruce w8bh.net

Farhan, The unit I received at FDIM works fine with Vcc from the barrel jack, but not from the battery pack. Peeking at the PCB, the power circuit has changed from the schematic you posted on Dec

Hi, just to add my 2p worth. I had this problem and like above, used a dummy load and transmitted an LSB signal. This was received by another rig and showed the BFO was way off. I replace the SMD
