Wayne, IMO, life itself should be a continuous learning experience (and that's what we emphasize - or did, in universities).? My problem comes in when people try to impose their priorities over my

Rob, you might want to try and run the IR510 power transistors from a separate, higher voltage power supply...maybe 18volts or so. I have a V4 that I run the finals at that level and see a big change

hello on completion of my v6 it did not work (locked up). ? tried various tricks no joy, so i thought reload the software watched farhans utube presentation? and im still stuffed i am no computer

Stage 3 - Replaced Q92, Q93, Q96, Q97 with 2N2222A (ended up putting them on the bottom of the board, was easier).? Paralleled R941, R942, R96, and R911 to get 11 ohms each.? Smoke test

Goes to show just how little progress we make despite all our tech: pen/pencil and paper still relied on to convey vital information. de ZL2DEX

I am using the 5 inch Nextion case from Sunil. Obviously none of the controls line up so I am using the front panel 3.5mm stereo jack analog/digital connection board. I have it all figured out except

Stage 2 - I replaced Q911 and Q912 with metal can 2N2222A's I got from Tayda.? Results are below.? Honestly, didn't seem any better than replacing Q90 with the BFR106.? Actually, "the curve" went

Hi Jim, Looks like a simple fix. Change the indicated line to read: gfxFont = (GFXfont*)&ubitx_font; Reed

My thought is to buy a bare board BITX20 and building it for 10 and 12 meters. I might even try for 6 meters. Not that I need another 6 meter rig. I have my 706 MK II G as well as the 25 watt

Hi, Looks like a pretty easy repair?? Just get a 3-pin header and some small diameter wire (wirewrap wire) and bridge the leads from the header pins over to the next parts connected to the traces

Ralph, please review the YouTube video I listed in my prior post. All of the instructions are there. 73 Evan AC9TU

Curt, I just saw your response. As you might have seen, I did get mine properly calibrated and operating earlier today. It was a calibration issue. With the stock v4 firmware it's all too easy to

Question to the group: I am new to kit assembly/building. I could not find the following information on the power supply jack. Is the center of this jack positive or negative? What size wire does the

I need to get an new barrel connector for DC power. What is the correct size (2.1 or 2.5mm)?

You have not loaded the ubitx ino codi into the Arduino Ide. The screenshots just shows an empty Arduino code. Please go to your local Ham-club or FabLab and ask for help there!

Hello, Could you please send a link to this group of parts so I can get a new one. My friends say it would be easier to replace than try to fix the board. thanks Scott

From the screenshots, you have not loaded the original version 6.1 files from Github.? All that you did was download code that does nothing.? Since the screen is controlled by the Nano, the screen
