Re: AO-51 Tx power?

2 Apr 2008

      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.

Any plans for automating the process so changes like this get auto- 
emailed to the list, so we can avoid these types of repeated inquiries?

Hello Jeff and BB,
AO-51 is running less power than last week.

The SQRX receiver is on for L band uplink for the BB
We are starting to enter a new eclipse cycle this week.

TX B (analog) as of this morning is 700 mW   (was 820 mW)
TX A (digital) as of this morning is 550 mW  (was 550 mW analog last 
week)
We will reduce power slowly until mid June (eclipse length maximum), 
then
slowly increase it until early Sept when we will again enter a no 
eclipse
period for a number of months.
It is easy to get spoiled with the higher output levels, the last  three
months.

Was the 70cm Tx power on AO-51 reduced with the latest mode  change?  I
was getting about the same signal levels this morning as in March.
