Hi All: A capture of TAG tonite....

For this capture I lifted the termination ends of my back to back EWE wire antennas from the terminations
and tied them together ungrounded. I used the NE EWE transformer to feed the receiver and the SW EWE
transformer was terminated with a 100 ohm resistor in the shack. The transformers and transmission lines
are isolated. That gives me a 13 x 70 x 13 foot EWE that I can switch NE or SW by swapping the termination
resistor and RX connections in the shack. EZNEC says I should get an extra 6dB of output level. So far it seems
like signals have risen more than the background noise, but it will take a few weeks of listening (or more)
to arrive at a conclusion. TAG is peaking a good 20dB out of the noise in a few places in the capture,
and I don't recall that kind of prior signal level on him. There must be something to that uV/m principle (hi)...
