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
