Dear list,
as you know, USRPs with a serial number below 500 cannot use newer
daughterboards because they fail to send the motherboard clock to the
daughterboard. There’s a very simple modification that can work around
this, and allow these old USRPs to use both old and new
daughterboards.
This mod is described on this page of our wiki:
