Today we put up a multi band antenna that can be used for 28, 21 and 14 MHz. The next couple of days we will give Oscar 7 a try when it is in mode A. I hope noise levels are much lower in mode A then in mode B. It is very difficult to work stations because of the high noise level when the satellite is in Mode B and is descending to the north.
I have no idea if a single multi band antenna will be enough for Mode A. Hope to hear you on Oscar 7.
