Hello all,

Thanks to Andre Kesteloo for forwarding the update on the AMRAD active whip design and pleased to see that the CP666 is still available.

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



Results of such IMD measurements can be dependent on the frequency difference between F1 and F2. In our case we chose 300 Hz, both signals being in the center  of the AM Broadcast band
