Regarding the advice for substuting the CP666 for a J310 and the quoted second and third order IMD figures, I have measured these and found IP2 = + 65 dBm and IP3 = + 30 dBm. At 12 volt the J310 should be biased for 10 -12 mA, excellent for battery operation. These figures are in the same league as for the CP666 and I am tempted to purchase one and find out if there is any difference in practice. Best regards, Roelof Bakker, pa0rdt
