Bill, I've finally had a chance to get on my laptop. For the 20x4 display, these are the relevant files from the CEC v1.2 binaries. UBITXV5_CEC_Vxxxxx_20P.hex : 20x04 Parallel LCD UBITXV5_CEC_Vxxxxx_2

My firmware won't run both the two line display and the nextion display. When I plug in the two line display I don't see proper characters. What this suggests to me is that if you can see the 2 line d

Just to let you know I have managed to change the CW Tone using the encoder push switch method. I started the memory manager and uploaded from the uBitX. The CW setup table in the KD8CEC firmware now

I would ask questions like: What is the DC applied voltage during TX? It sounds low for CW even. For CW I'd expect near 10-12W however if you Power supply is below 12V what you are getting is then goo

I was able to use finally the NJM without issues; audio is really strong with the v2 model.

For the clicking, check the wiring on your key and mic inputs. Also, did you install the 4.7k pull up resistor? Did you make any adjustments on the biasing pots on the main board (the blue pots)?

Ah...good info. Thanks! I also added a BEC for some the 5v needs (plus a usb charge port), and a big dc-Dc buck converter for the 12v board. Now I can power it up with anything (almost) and the finals

I had the same problem. I fixed it by doing the following: After tripple verifying that the wiring was correct I removed the encoder from the chassis, and sanded the metal bare on the inside of the ch

Firstly, thank you all for your help and encouragement. Then I found that the Rx worked better when the coax shield was not connected at the tuner... so the cable could then work as an antenna... trac

Hey Curt, I’m feeding the ubitx with a cheap lab bench power supply. It’s intended more for electronics hobbyists than for ham radio, so it’s entirely possible that it is not a clean power source. Unf

Many thanks all. That clears up my question about the BFO setting. On the firmware, I used the hex file for v5 and my standard (as shipped) display. I assumed this didn’t need to be tweaked further, b

Thanks Vic. I am not the only one with this issue then. There have been a few other posts on this topic but no conclusions or solutions mentioned. I am trying different 2.8_E and 3.2_E firmware versio

I have the same V.4 high-pitch oscillation problem and have had no luck addressing the problem. I have done the following: 1) Rewired all audio pathways with grounded RG174. 2) I added an electrolytic

Hello to the Group ! I have the same problem.I built the uBitx V3 from scratch.First I thought that I have ground loops ,but doesn't solve the problem. After many days of research I noticed that if I

Jens, I assume the rig is transmitting when first powered up, unless you plug in the microphone. I think your microphone jack may be grounding the orange PTT wire, except when the microphone is plugge

The following observations may be of interest to others having just got round to completing my V5 build. 1) For safety I made use of the SMT reverse polarity protection circuit by KC9ON to simplify th

Sounds like it was a bad connection somewhere in the wiring, or perhaps just a flaky power switch. If it happens again, I suggest you put the multimeter in a mode to measure volts DC, then put one lea
