I am new to satellite operations. I tried to access Lilacsat2 from a SOTA
summit today and failed. I did manage to call into AO-92 yesterday and I
was heard by four stations (but I couldn't receive the downlink).
I was using a 2m dipole to transmit (I am fairly confident I was getting
into the satellite today) and a 2 element 70cm yagi. Now, I think two
things went wrong. Firstly, I had no way of directing the antenna
accurately (I had to guess on the angle and azimuth), and secondly, the
antenna isn't very powerful, is small and isn't tuned brilliantly (it's a
70cm yagi but I get SWR of 2.2 on 70cm).
Firstly, I'm wondering how precise you need to be in directing the beam?
Can I just hold it in the vague direction that the satellite is approaching
from, or do I need to work out the headings?
Secondly, I am wondering if my equipment is likely to cut it. As I said,
yesterday I was told that my signal was getting in - quiet but fully
readable using my Diamond x30. I don't want to transmit if I can't receive
in case I talk over someone or cause some interference. I won't be able to
buy an arrow or a powerful beam antenna for around a year, but I am really
desperate to work the satellites. Wondering if there are any ways that I
can use my current equipment in order to work it (whether that be from my
Home QTH or from a SOTA summit).

Hoping for some advice.. I would love to hear stories of you working
satellites during a Summits On The Air activation, and I would be
interested to hear of your station setup (and whether you have had success
with a minimal setup like mine).
