Ok Steve. I am listening to 145.935 MHz +/- doppler in the USB mode. The bird is using power output which is a little higher than originally planned but still lower that normal use in the future. It has a nice strong signal here. I would think you could hear it with a 1/4 wave whip or ground plane antenna on a high elevation pass. My eggbeater is only 10 feet off the ground with a large pin oak tree blocking to the south and my house blocking to the north.
Hope you get to hear the bird. Let me know if I can help in any way.
