At 1815 CST, NC has been good copy for the past hour and a half, since I turned on the receiver just before sunset. Another signal started showing up almost on top of Dex, and it drifts upward during key-down intervals. Looks like it's "PI". Faint signal very close to 185.2995; two more at 185.301 and 185.3015 that haven't provided a positive ID. Might be a good night on LF. Lyle, K0LR
