I think we need to use lowest frequency for the down link as 6dB of path
loss occurs for every octave increase in frequency. 2M to 70cm = (-9dB).
This keeps the power budget down on the space craft. It also helps hearing
the satellite and causes O/E problems to gravitate to the up link.

While I certainly agree with the intent of the QRP transponder on  
AO-51; you might want to consider the possibility that the station  
calling CQ may not be aware of it.  Not all the hams who work, or  
attempt to work the satellites are active on this reflector, or even  
read up on how to properly work a satellite.

I always try to send an email to the person who can't hear anything,  
and 9 times out of 10 I receive an email back thanking me for letting  
them know they were heard, and asking me why they can't seem to hear  
anything.  It then translates into a bit of Elmering to get them to  
put up either better antennas or just send them towards some of the  
articles on the Amsat web page.

A number of those hams are now active 'new' hams on the birds.  If you  
have his call, why not send them a nice email, saying they were heard,  
and it's not proper etiquette to call CQ on an FM satellite  
continuously; and point them to this reflector or the AMSAT web.

Recently on this reflector there have been several posts about the  
over abundance of activity, abuse and interference on AO-51; even one  
that surprised the heck out of me from one of the AMSAT officers.   
Seems to me that we might need another LEO or 2 to tied us over since  
the loss of AO-27 and AO-16.   While it seems that most of the posts  
on here eventually go on a tangent towards the lack of a HEO, the use  
of the LEOS are exponentially going up.  Just my .02 worth.
