Well written bush pelican.
As has been said before, the real reason that frequencies seem congested now is due to the massive amalgamation of areas. The massive grouping of frequencies tied into each other enabling you to hear irrelevant traffic literally hundreds of miles away is why there is so much perceived radio chatter.
The solution it seems now is to discourage pilots form using the radio at all by hiding frequencies and emphasizing a dangerous, misguided and unworkable concept known as “see and avoid”.
The educational material also makes it seem like transponders are the solution to traffic conflict, and as long as you have it switched on there won’t be a problem.
This new airspace system is taking us back to the dark ages.
The utterly ludicrous idea of having aircraft sharing the same piece of sky on different frequencies relying on the ability of a person to see another aircraft on a collision course seems to be totally lost on those promoting it.
