Ion, Do you see "loading standard settings..." on the display each time you power on the radio? If so, it means that for some reason your Raduino restores the "factory" settings each time at power on.

Hi Ludwig, Surprised of no replies on this, so I'll throw out a few ideas to stir up the conversation. From your description, it seems to be an issue with the I2C/SI5351. 1. I?doubt there is a

Thanks Mark, haven't measured anything yet....if the Nextion on a Sunil case proves unworkable, well, will just have to leave v1 uBitx in the case and buy a shiny new v4 for the Nextion version, with

Many thanks all suggestions. Guy's was the best for me. Adjusted Radio Shack simple stripper and it works perfectly. John Vo1jcc.

Sorry Doug, Got you confused with the OP. Joel N6ALT

If you go here you will find all you need to know about the caoibration. http://www.hamskey.com/2018/05/frequency-adjustment-of-ubitx-si5351.html

Thank you Ralph for your reply. I have MASTER_CAL as 92 68 00 00 from an attempt to calibrate by zero-beating an AM broadcast station. Is there any procedure to get new values for LSB_CAL, USB_CAL and

I wasn't complaining at all.? Just sharing my recent experience with the original poster. ? -- www.bitxmap.com ( http://www.bitxmap.com )

I enlarged the window of one of my earlier uBITX rigs (that had been installed in a Circuit Specialists extruded aluminum case) to fit the 3.2 inch Enhanced Nextion. Originally I had used a 4 line by

Jeff, We haven't had the time to attempt getting CEC software to work on the RadI2Cino.? It's different in hardware than the original Raduino enough that We'd have to re-work a lot of Ian's CEC code

Doug, We are experiencing a solar storm right now and band conditions are bad but not completely gone. Yesterday I threw a cheapo 10 meter rig in my car and a Mag mount on the roof and worked a

Always signals on CW & FT8 tho.? I'm working on my code ahead again and FT8 is a no brainer. 73, Bo W4GHV since '54

Thanks lots! ?Now how about a bunch of hash tags to help sort things. ? ?#needhelp/broke. ? # usefulmod etx

Having the si5351 on the main board is particularly nice because it keeps the RF traces shorter. The Arduino on the mother board makes less sense since everyone seems to be modifying that part of the

what mode?? what bands? Lately I've been working mostly digital on 30m and 20m with a little 17m and 15m sprinkled in for variety because I can do that and work my day job.? While all the bands do

Dug up the bare link... https://www.aliexpress.com/item/New-45W-SSB-linear-Power-Amplifier-Kits-With-low-pass-filter-for-transceiver-Radio-HF-FM/32574683152.html Looks interesting.

I had luck enough to make a couple of contacts last weekend, but since then the bands seem to have dug a hole, crawled in, and pulled the hole in behind them. I can't hear *anything* out there except

Peter, That is a very nice layout. I'm torn though because I really like the ease of soldering SMD parts, it is much faster, however I like having the si5351 and Arduino onboard. This would make a

.Jack, First, upload Raduino software v 1.27.7 how is described in github was Not possible because I can not select the port. (Win7 and notebook) why.?.? With win10 on my sons pc it was no problem.

Forgot to add that I flashed back to version 1.09 and I was able to calibrate and the radio remembers the calibration and the last frequency used. Thank you again, -- Ion VA3NOI
