I haven't experienced any noise problems.? I still must shorten some wires and think about a final mounting arrangement. -- Jon Titus, KZ1G Herriman, UT USA

Very nice, Jack.? Have you described your setup?? I'm interested in the type of display and processor board, and the software. -- Jon Titus, KZ1G Herriman, UT USA

I used a plastic cutting board and some pieces of single sided copper clad board mounted with "L" brackets as a temporary "enclosure" to mount the board and controls ?so that I can play with mods and

Arv, Appreciated for your comments and pointers of details. Certainly let me try some mods you advised after I set up my ubitx as it is. I am not a hardware guy and so need a little more time to

Nice...any more pictures?? Jack, W8TEE

Yes, Bill. As far as I know, the distortion issue comes up with only v4 ubitx, however it’s just a matter of degree. I already placed my order with DHL, while taking a train back home today! :) I

Good rundown on warnings. Fortunately we haven't had a new idealistic programmer decide to set the?-Werror complier flag yet. That was great fun unleashed at the worst possible moment. Tom, wb6b

Hi raj, again many thanks for your kindleness and help. I am appriciate this very much and Hope for succesful repair. When my bitx was still working I developed a combination of agc and rx muting to

Don, Just checked, feedback is affected by level of volume control. More with higher volume, quits with volume all the way down, mike unplugged, or plugged in, also with audio coming from the computer

Hiro The distortion issue seems to be more related to audio level and impedance and quality of the attached speaker. Layout of the uBITX-4 audio output section allows one to make changes like changing

Elmar, Change the nano on the raduino and reprogram. Raj

Hiro, JJ1FXF It is easy to build your own copy of the uBITX-4 audio section to experiment with. You will need two 2N3904 and one 2N3906 and assorted resistors and capacitors. This will let you play

Rick, Yes, having insufficient filtering will allow all sorts of problems. At this point, a few of those experiencing these problems are finding that those signals are getting through to the 5 volt

The new audio amp in the V4 uBITS is a very common design in inexpensive audio equipment for many years. It could be sensitive to power supply voltage levels and if you are using it at below its

Nice! Sure beats the days of drilling and filing of steel cabinets. Bo W4GHV since '54

Arvo, Nice catch...I'm going to move the fan supply to same spot. Thanks Vince N2AIE

Hi, I have V3 with a socketed audio chip labeled as Feb 2018. It worked right out of the box - as advertised. I have not had to make *any* mods at all. I do expect to install the CEC software but that

Hello raj, I am very glad to See your fast response. sorry to say I killed my Raduino by myself. Build the bitx in a new case and wiring one of the normally unused cables to the 12 Volt rail. Now I am

Don, I too am hearing the audio in the speaker during transmission. I noticed it first when transmitting digital using FT8, in fact at times the transmitter went into ocillations with the feedback. I
