How much more difficult was working two linear satellites with regard to doppler correction, given that the satellites are moving relative to each other as well as the operator??

Hello All Here's an interesting endeavor. The downlink on AO-7 mode B is 145.950 which is the uplink for FO-29. So you could hear yourself (or anyone else on the FO-29 downlink at 435.850, when both are in view. I think there was something like this back in the days of the RS birds. Why bother? Well we have to do something to keep our interest going while waiting for the next HEO. Plus it's fun. 73 Bob W7LRD Seattle

Hi Bob, W7LRD
Since OSCAR-7 mode B and FO-29 mode-J have both inverting transponders using SSB it happens that to be received as usually in USB over the FO-29 downlink we must transmit as well USB into the OSCAR-7 uplink.
Since the noise translated by OSCAR-7 mode-B is very high probably a try on CW will be convenient.
As Rick WA4NVM pointed out with OSCAR-7 mode-B and OSCAR-8 mode-J it was a common practice.
