and (a couple of times) even down to 100mW and still made contacts.

Definitely work on the receive side of the station before transmitting. Since
only a few watts - or less - is all you need for the satellite to hear
you, work on
the receive side of your station so you can hear those low-powered signals
coming down to you.
For most of the past 2 months, if I am on the satellites I am using an HT (Icom
IC-W32A or IC-T7H) and a long telescoping whip (Maldol AH-510R is my
preferred whip, but I also have an AL-800H whip in my HT bag). I could make
a few more contacts with a directional antenna instead of the long whip, but
having a small bag with everything I need for my FM satellite station is pretty
Good luck, and 73!
