Re: Si5351A blown (IC1) QCX transceiver.

Hi all

Another reminder, just in case it helps anyone: when replacing an Si5351A chip please be sure to purchase Si5351A-B-GT or Si5351A-B-GTR (Matt's appears to be correct). Do not be tempted to buy a part number such as Si5351A-Bxxxxx-GT [R] because the xxxxx indicates it is a customized chip for a particular customer's requirements; these typically operate on I2C bus addresses other than 0x60. These non-standard chips will NOT work in QRP Labs kits.
