It takes a little more effort to utilize either Mode A or Mode B than a handheld radio and a handheld antenna like many are using to access the FM satellites. Also, at least in this country, a fair number of operators have only FM equipment for either 2-meters or 70 cm and not CW / SSB equipment that is required to operate through OSCAR VII. As such, much less activity than when the satellite first went "up" in the 1970s. Glen, K9STH AMSAT-239 / LM-463 Website: https://k9sth.net

I’ve put out calls a number of times on AO-07 as it passes over Australia and while I hear my own single back clearly I’ve never had a reply. I guess I’m curious if there is a calling protocol I’m missing, or a particular part of the passband etc? As a higher altitude bird with great coverage it would seems logical to me that it would be popular? Am I missing something?
