Its for the Real time clock. its not needed for now. if someone implements it in the firmware then it could be used.

My v4 ubitx has low audio if I try to use a speaker, with headphones it is reasonable.

As did I, David. Thanks for the reply. The popularity of the uBitX continues I see. Hal AC0AX

Not to beat a dead horse but are there any shipping issues. Last I read was that the backlog was gone. I placed my order last week and have yet to receive a notice that my ubitx has shipped. Thanks Ha

I got my copy from Amazon. I bought parts for the projects over a year ago, now if I could just get time to build them.

Mine did the same thing. I had to sign for mine as well when it arrived. 73's Hal AC0AX

Tayda electronics has them.

Mine arrived today as well. I didn't have any thing wrong with mine, nothing broken or bent. As for the shipping tracking it never did update, it still shows that it's in India. Hal AC0AX
