In my case it has been a while. I was more expressing surprise that with all the efforts to get people onto discrete frequncies so as to reduce congestion, it seems it has only made it worse. I did consider that radios are cheaper and much more portable now, but that the rise in the numbers of sport flying would be offsetting the decline in traditional GA flying. As suggested, perhaps more effort should be expended into promoting more 'efficient" use of radios.
