Thanks, Adrian.  I wanted to make sure that my notes were correct, as I am
not very experienced and have made mistakes in using the wrong mode.
Fortunately, a polite ham would gently correct me on the air, without making
me feel too dumb J

 

And I appreciate your kind response as well, Adrian.  Just one more reason
why I enjoy this hobby and AMSAT.  Thanks, 73

Mark,

Both our responses are correct. I decided to leave AO-7 Mode A off from my
initial response to Jerry as few people use that mode these days.   This is
a non inverting transponder, therefore USB-Up and USB-Down.    

I was trying to address Jerry's request for helping our newcomers. Their
concentration would most likely be on FO-29, HO-68, AO7 (mode B) and VO52.
All four of these satellites are LSB Up and USB down as you indicated below.

A great web site where all this information is nicely detailed is at:
http://www.dk3wn.info/satellites.shtml  See each satellite page.

Adrian, I had a thread from December 2008 on this board that said the
following:

>> VO-52 is LSB on the uhf uplink and USB on the vhf downlink 
>> FO-29 is LSB on the vhf uplink and USB on the UHF downlink. 
>> AO-7 is LSB on the uhf uplink and USB on the vhf downlink. Mode B
>> AO-7 is USB on the vhf uplink and USB on the 10m downlink  Mode A 

Can you please comment?

Jerry,

Linear satellites today use LSB for the Uplink and USB for the downlink by 
general agreement. 


Also by agreement:

CW is on the lower 1/3 of the downlink bandpass.
Mixed Modes are in the center 1/3 of the downlink bandpass.
SSB is in the top 1/3 of the downlink bandpass.

            Hi :  I sent a couple friends that are interested to the AMSAT 
website.
                    I told them to look at all the satellites.
                      They found the site  had  all satellites on it.
                    When they brought up the sats  they didn,t put on the
                        sidebands on the linear birds, the up and downlinks 
.
                    I mean the upper and lower sidebands for these birds.
                      So I sent them to the UK site and they were there.
                    They didn,t have Oscar 68 on there though.
  Jerry w0sat
