To say the activity is down on the linear birds in recent years is simply incorrect. And more hams are operating satellites away from home than ever before.
Since my Board of Directors report from sometime ago was used as evidence, let me state that activity on the linear transponders -is- up from when I wrote that at least a year (or more?) ago. It's not uncommon to hear 4-5 qsos going at once now. That hasn't always been the case in years past.
