Hi Joe, WB9SBD
The problem here with many new and young satellite operators is like to have many young sparrow that don't know how good is the flavour of wheat

I still to this day fail to see how hard it is to twist a VFO knob.
Have we all become soo much appliance operators that we all have forgot to know how to turn a VFO knob to keep someone in tune?
All my early days of Oscar operations we were constantly twisting the large knob. that is what it's for.
wow. un real..

Hi, The e-mail from I8CVS brings the issue up again. Why not just be happy to get one more transponder for us to use ? If you do not want to use a FM transponder so that be it.
It is interesting to note that there are far more operators on the FM transponder satellites than on the linear satellites in Low Earth Orbit.
Anyway the choice is made by the ones who make and finance the satellites and transponders.
With a height of 500 km FM is probably the way to go. The dopper shift is large. It may be a bad choice for a linear transponder unless you assume that everyone are using full doppler tracking :-)
Sumbandilasat it a very good satellite for operators working portable or mobile. The downlink is strong and it will be better to use it once things settle down. Every time we have a new satellite we have very many wanting to try it out.
I think we should say thank you to our friends in SA for a new one.
