[amsat-bb] Re: AO-51 Tx power?

[Gould Smith]

Hi Alex,

I don't have any plans to automate it.  Depending upon the mode(s) in use on 
AO-51, I manually adjust the TX power to get through eclipse.  As long as 
the BB is operational these settings are available in the downlinked 
telemetry.
If you don't have a 9600 bps modem, Douglas Quagliana, KA2UPW has an 
operational, beta telemetry decoder/display that uses your sound card.  This 
is available on the AMSAT Digital Disk.

73,
Gould, WA4SXM
