[amsat-bb] Re: FUNCUBE-1/AO-73 reception issue

[Rick Walter]

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.

Rick
