Right now I've built the SMD1206 pcb Daylight allanalog circuit ( less the power RF) 80x70mm, but I can do better, of course, this is just a test. Some more? questions: 1) What the exact frequency of

It is best if you use a controlled current supply. The 10A meanwell is highly recommended. Your sbitx will arrive with the switching regulator installed and the bias set. Don't try alignment. It comes

Hi All I am receiving the SBITX this week per DHL.? Any cautions that I should be aware of?? I have been reading up on the 5V LDO supply and replacements with a buck converter. Just wondering if

Hi Scttmtclf and Mark, I used the same regulator and yes, you can test the radio with just the regulator and you are correct, don’t transmit. ?Testing the PA transistors is easy but I would not

Ah the joys of trying to relearn AP courses in order to teach them at a private high school.... For some lighter reading, I perused Jack & Albert's text on their radio -- wonderful illustrations and

Jack, I am at home and downloaded the newest file in the groups.io file section, extracted it, and compiled it.? I did not get any errors.? Here is the tools dropdown in the Arduino IDE: 73 Evan

Should R51 be connected to TX or 12V? On the schematic it's not connected to anything. In the PTO the text talks about a 7809 but the schematic shows 7805. On a happy note, the PTO 3D print worked

Thanks Ashhar. Perhaps I should have thought of volunteering to distribute for Australian purchasers earlier but hopefully the postage costs for HF Sigs weren't too high. . 73 Bill. VK7MX

You are correct. I should have read the email better. I will blame it on grandkids distraction. I have not run into the issue you describe. ?I would verify that you have the correct card selected and

Thanks for the quick answer Evan, Now I am confused (more). I thought that the Nextion editor construct was a separate issue from the uBITX V6 software compile. I am missing something(s) I guess. Is

You may need to use the LTS version of the Nextion editor. Look for it on the Nextion web page. I am away from my qth right now. ?If you can not find it I will post the link when I get home. 73 Evan

Need help troubleshooting. #sketch-too-big For those who have successfully installed the latest drop of N8ME_2_VU3GAO_Mods, what Arduino ISP version are you using? -What are the parameters in the ISP

I have some updates available for testing here: https://github.com/k3ng/sbitx-k3ng/tree/2022.09.06.0115 <https://github.com/k3ng/sbitx-k3ng/tree/2022.09.06.0115> This includes the following

Dave Thanks for the kind words. I not that young and I forgot more than I know. I was licensed in 1979 ask KA3DFK I took off about 30 years an got back in to it during the Pandemic. That’s how I got

Actually there’s already literature on it. I’m going to dig again ex: Re: #uBITX Firmware KD8CEC - IF-Shift etc. (groups.io) ( /g/BITX20/message/44278 ) [email protected] | Need

This is the one I have been using for a while. https://www.amazon.com/dp/B08R6337QY I also need to swap my IRFZ24 FETs but that was due to a high SWR scenario, the buck converter is still working

Hello, When analyzing the programs KD8CEC or Ubitx V4,5,6 I have a little trouble to understand how the different values of First IF, Second USB, Second LSB and int USB are calculated. In the KD8CEC

Scott, Do you have a part number for your buck converter?? I think it's amazing that Ashar is sending replacements out.? However I am hoping to do a POTA activation next Thursday and I'd like to

Hi, send me a private message?and I will send you the .apk file. The link only contains the source code. Ramón

Begin by looking at the 5v regulator. It is the 388 or its replacement switching regulator just next to the 12 volt input to the unit. Pete WK8S
