Thanks, I got it calibrated, and as of this afternoon have made 3 QSOs to POTA stations on it. :) 73 de NM9O

Matt, Glad to hear you found the problem. Here is a link to a video by Ashhar Farhan on calibrating and setting the BFO. It is for the v6 as the instructions are using the v6 controls. The same basic

Evan, Thank you! You picked exactly what I had missed, the 4.7k resistor. Now I just need to get, or put together, a microphone, check out the KD8CEC firmware potentially, and get it aligned :) 73 de

I bought a ubitx v3 a few years ago, and also got the case. I got busy, and didn't actually get it put together until today. No real issues, until I powered it up, at first it said it was on LSB, but

Hi David, You didn't actually step on toes. You did add your post to a 'thread' about something else and that reduces your chances of getting the right answers. Somewhere in the files section of this

Dear OM Evan, i am really excited to see your logical pointers. I will try these out but after some time due to medical issues at home. Ofcourse, I will update you as to how it goes. Thanks at ton! 73

The Si5351 seldom fails for no reason, and the three output drivers are somewhat protected by the series 0.1uF caps. The 3.3v regulator in the Nano's CH340 chip that powers the Si5351 protects it from

vu2rjv, The information that you have given so far points to the Si5351 chip. To verify, I would pull the Raduino from the rig (with the display) and try powering from your computer USB or a 5volt USB

Check L1,2,3,4 end to end continuity TP1 to TP2. Sometimes I have seen coil soldering give up. In your case both TX and RX not working so it has to be a common path like L5 and L7. Raj
