Re: New wiring diagram version
Thank you Jerry, For now I've just reworked the drawings, based on the old one. It's better quality and very good to print. I've some questions on my side too : What is really the difference beetween

Re: New wiring diagram version
Good to have an alternate drawing of how to wire up a uBitx. We often have questions here from puzzled kit builders. However, The 2 reverse protection diodes should be after the fuses, not before, so

Re: BITX shoes?
I ordered RMItaly KL203 and will give it a short to work with ubitx once it arrives here.

The yellow wire goes to the pin at the end of the connector. Pauls photo agrees with the "wiring up" drawing here: http://www.hfsignals.com/index.php/2017/11/23/wiring-up-the-bitx40/ except that Paul

Re: BitX40
Hi Paul Thanks for that. So does the yellow wire go into the pin nearest the 575 handwritten on my board? Only your board looks different to mine. Also, what happens about connecting the volume
