I might have missed something, Thomas, but I believe Luc recommended a 'slightly elliptical orbit', not necessarily a HEO one. Do these need to be the same thing? An elliptical MEO would allow for periods of more challenging operation with better opportunities for DX alternating with periods of lower pass loss, but smaller footprint. This might well be something that AMSAT-India could come to ISRO to ask for. Of course, none of this takes away from the excellent work of AMSAT-DL on P3E, which we all eagerly support. 73, Bruce VE9QRP -- http://ve9qrp.blogspot.com _______________________________________________ Sent via amsat...@amsat.org.
