FYI,

I designed that circuit and C4,5 and 6 are supposed to be .01 RF Bypass capacitors. ?.1's may be too much capacitance for the circuit to work properly and I actually left them out in the original design. ?I didn't have any RF problems but I have my uBITX in a well shielded case made from double sided PC material with all sides connected together and grounded. ?

BTW qrpguys negotiated with me for the rights to market that design and did a really nice job on the PC boards.
