Thanks to K3LR and KA1J and NS7V for sending many suggestions!
My NCC-2 with 2 DX Engineering active verticals spaced 50' apart didn't seem
to offer any peaks or nulls or noise reduction on 160M compared to the top
loaded transmit vertical. It does work on 40M and less so on 80M. On the
WWV 2.5
I have the NCC-2 and 2 of the DX Engineering active verticals, the CQWW CW
was the first test drive. VERY impressive results on 40M, less so on 80M
and even less so on 160, compared to listening to the transmit antennas,
an OCF on 40/80 and top loaded vertical on 160. Just not much peaking or
