Case Study Near Mid Air Glider and C421 - Benefits of PowerFlarm and Transponders

Yes, I heard them. IIRC, they informed the 421 of the presence of the
glider but gave no vector for spacing. I'm assuming the 421 was on an
IFR flight plan and therefore had to maintain his assigned heading. Of
course, he could have asked for a vector to avoid traffic. I've done
that many times. He did not, or at least I did not hear it.

Monitoring of local ARTCC or Approach frequencies for traffic, I've found is not worth the trouble.
So you did not hear ATC communicating with the C421 about the conflict? Was there any way for ATC to contact you by radio?

IRRC ATC is not tasked to maintain IFR to VFR separation (?) (only IFR to IFR). So according to protocol, was ATC waiting for 421 to request vector to avoid traffic?

(I really have no idea what I'm talking about, but I'd like to understand this scenario.)

Thanks, Walt.
With transponder and on ATC frequency you will hear other pilots being warned of your position relative to theirs, just as the 421 in this case. Typically "traffic, a glider, (distance, relative direction, altitude), maneuvering". Personally haven't heard detail on climb, whether rate or just "climbing".
Flying with another glider, each using discrete codes ATC has not issued maneuvering instructions in my experience. Perhaps just "do you see the other glider?"
The controller would assume an aicraft squawking VFR was on another frequency.
Even before the 1201 then 1202 VFR codes, controllers could tell a glider squawking 1200 from other aircraft. A fiberglass glider without transponder could be invisible to radar.
If something like this happens to you, it's possible to submit a NASA form which is supposed to be anonymous and used to help prevent future occurrences.
