Agra. I really hope you remain vigilant and keep a good lookout. And remember many IFR pilots descending into class G don't give a full position report. How will you have " radio arranged separation" with them.
Thank you for your concern. I do and I will.
If these IFR pilots are not making a mandatory call, that means they are at fault, not the system. And whatever calls they do make, that's still better than the complete silence I'd hear if I was on a different frequency.
Despite your inference, I've never claimed that radio was the only tool available for arranging separation. But IMHO it's lunacy to have it, and not take advantage of it.
