Re: Overhauling my first and second U3s. PA bias and power output with (3) BS170 transistors question(s)
Mike
I had to unscrew mine.
I'd suggest ignoring Hans on this point and only use a few screws like I did when I reassembled.

Re: QCX firmware 1.00d release
Hi Hans,
does the 1.00d also contain the fix for the WSPR encoding (as described in?/g/QRPLabs/message/18134 )? Or will this be included in a future release?

Hi Keith
You can remove it on all. It was only intended to be an additional
protection during shipment.

Thanks for the info. I removed the tape on the first
