Give it a while, there are probably 10x the users now as there will be in 3 months. 25w will seem excessive by then.

I have the IC-910 set to about 25 watts on UHF.  I have made one contact on AO-73.  It has taken me forever to get the doppler correct as I usually cannot hear my signal.    Last night my returning signal was extremely strong for about 1 minute.  In comparison, the received signal from FO-29 is extremely strong so I am assuming that my UHF antenna is working fine.  Like Perry, I have never experienced this before.  At times AO-73 takes some very deep fades (telemetry). With such a small little cube, I would not think the satellite is blocking the antenna (although 4 inches is starting to get close to 435 wavelength.  The frequency offset confused me at first.  I just kept cranking up the frequency and there I was but very, very weak. I'm not gripping as I am having a blast.  Those of you with experience are probably getting a laugh at what I report.  I am a newbie to this satellite stuff and learning as I go and extremely excited to make even one contact.  Maybe the geese overhead are causing me some problems. :-)
