Following my experiment reading AO-16 last night with an indoor 1/4wave magmount, I'd hoped to try today with a basic antenna attached to my FT-817. this antenna is a BNC connector with three stiff copper wires attached, two to the ground, one to the pin, in the classic 120 degree arrangement.

Alas, by the time I made it home, the bird was only at about 2 deg, over the N. pole (its silence quite possibly due to inactivity) so I switched to CO-55's nominal 100mW CW signal. Again, indoors through about three walls and perhaps the roof of this wood-frame home I was able to hear CW. I engaged the narrow CW filter, which then made it intelligible, and then walked toward the other end of the house so that a single outer wall was between me and the bird. At about 2 deg. elevation to the North, I could no longer copy the CW. It was about a 559 until then.

Granted, my house is surrounded by a 6 acre field and on slight hill. I have very little noise on 435MHz that I can tell. Nevertheless, there was enough of a signal above the noise that I think this could be reproduced easily in many locations. It strikes me as a very simple experiment, ideal for in-class or for a demo to a ham club. In fact, the constancy of the cubesat telemetry makes the demonstration easier to understand and conduct. One could get the sat tuned in then hand the knob over to someone else so that they can 'feel' the doppler as they catch up with the bird.
