Hi Alan, I use 10 watts from my Icom IC-9700. I run about 100 feet of LMR 600 coax so maybe 5 watts to the antenna. I use a 35 element yagi antenna. I made the satellite today at 14 degrees elevation OK. 73sLynnKD9BVG

Using 10 Watts, I have not been able to get into AO-92 L Band.
From the AO-92 web site:
================
......Since the 435 MHz uplink antenna is used to receive the 1267 MHz signals and may present a mismatch at that frequency, pre-launch estimates suggest that a power level of 100 watts ERP will be required for horizon-to-horizon access in Mode L/v. AMSAT Engineering will issue further guidance after in-orbit testing. Look for future articles on the AMSAT website and in The AMSAT Journal for equipment ideas and tutorials for accessing the L-band uplink. ====================
Perhaps my 10 Watts are too low. Have there been updates from AMSAT on recommended L band power? What power do others run?
