I had/have the same question and stared at images and combed the web quite a bit trying to figure out what to do. My conclusion (thus far) is that there are too may mic configurations out there, so it

Hi Tiery The price is 170 euros plus shipping costs. Paypal Payement. I am currently on Christmas holidays and I go home on December 28th. 73 QRO Gilles - F1BFU /Fr

Here is a link to the HF Signals wire up instructions: http://www.hfsignals.com/index.php/ubitx-wire-up/ The USB port for the nano is between the nano and Raduino board.? Due to the history behind

First of all, let me apologize for asking what will be (hopefully) simple questions. This is the second kit radio that I have assembled and the first one with voice capabilities. My other radios are

While waiting for time to finish building my uBITX (and a suitable antennal—gotta love condo living!), I've been working on proliferation peripheral projects to make my rig my own. I'm an avid CAD

Don’t worry about transmit until you fix it in receive. Start tapping away, initially with a finger then a hard plastic probe. First determine if it’s on the main (RF) board or not. If it’s the

Multi-layer ceramic capacitors can be microphonic due to piezoelectric effects. Dave Jones from EEVBlog has at least one video on the phenomenon. Even a simple ceramic disc cap can show microphonic

Hi Terry I have a uBitx v3 for sale. It is a purchased card all built and set by Ashar. I just received the Sunnil front panel wiring kit as well as the cabinet. Just serve in reception for the

On one of mine it was the stock volume control. One end of the substrate seemed to have a bad connection with the pin. Swapped it out and it solved the problem. 73, Don

Jim, W0EB Thank-you for filling me in on the history.? It makes perfect sense that they would not want to redesign the Raduino board when a simple change solves the issue. All, Apologize to the group

Hello everyone! I am currently playing a little with my Ubitx and I have an issue which bothers we since the beginning. The microphone gain is not pleasing me. I literally have to scream into it for

My board also experienced the microphonic issue when first built.? I then did some case modes, rewired, added some snap on ferrites to dampen RF, tuned it up again, and over the multiple times

it is a .1 microFarad (100 nF) dc blocking capacitor for the BFO.? The detector will not work without that signal, and it cannot be just bridged.? I would get a surface mount capacitor to replace

Jeff, Please let us know what software you are trying to use and give us the URL for the source so we can be more effective at helping. The statements " I tried loading the original software for the

Cap is in series, so that's a DC blocking, AC coupling cap from CLK0 on the SI5351. Regards, Gary

Mine also, but not enough to be an issue.? Have not figured out why, but there was another post regarding this (I forget the exact...) a little while back. Woody? KZ4AK

Most likely the torroid chokes.. Hot melt glue or wax them in place.73 de Mike

When I say "microphony" I mean that the circuit boards are acting as a microphone - any slight tap on the case can be heard loudly in the phones. I haven't tried it on transmit yet, so I don't know

Thank you, Kurt, will find and download these photos for future reference. MicroBitx is now working, had installed what I turns out to have been a corrupt version of the latest KD8CEC sketch, BFO
