[amsat-bb] AO-92 L Band Power

[Cal Spreitzer]

Alan,

I'm using 10w (ICOM IC-9700) through 50 feet LMR-400 into a Directive
Systems 24 Element Loop Yagi. No issues getting in when the L-Band is
enabled ( currently on Wednesday's )

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?
