Narrative:

My aircraft was 310 degrees magnetic heading. Other aircraft passed off my right wing approximately magnetic heading 330 degrees. When advised of the near miss, approach first reported 'thank you.' when I let them know that was not an acceptable answer, they said they had no altitude read out on the other aircraft. The other aircraft appeared to be a very fast aeronautical commander twin which was going 50-70 KTS faster than my 160 KT (TAS). That means that the other pilot, who was at this correct VFR altitude and was multi rated, was flying with no altitude read out. I seriously question the truthfulness of approach's story. I think they did not provide adequate notice to an aircraft under their care for VFR flight following.

Title: GA PLT COMPLAINS TO SCK APCH BECAUSE THEY DID NOT ISSUE TFC ADVISORIES ON AN OVERTAKING TWIN COMMANDER.

Narrative: MY ACFT WAS 310 DEGS MAGNETIC HEADING. OTHER ACFT PASSED OFF MY RIGHT WING APPROX MAGNETIC HEADING 330 DEGS. WHEN ADVISED OF THE NEAR MISS, APCH FIRST RPTED 'THANK YOU.' WHEN I LET THEM KNOW THAT WAS NOT AN ACCEPTABLE ANSWER, THEY SAID THEY HAD NO ALT READ OUT ON THE OTHER ACFT. THE OTHER ACFT APPEARED TO BE A VERY FAST AERO COMMANDER TWIN WHICH WAS GOING 50-70 KTS FASTER THAN MY 160 KT (TAS). THAT MEANS THAT THE OTHER PLT, WHO WAS AT THIS CORRECT VFR ALT AND WAS MULTI RATED, WAS FLYING WITH NO ALT READ OUT. I SERIOUSLY QUESTION THE TRUTHFULNESS OF APCH'S STORY. I THINK THEY DID NOT PROVIDE ADEQUATE NOTICE TO AN ACFT UNDER THEIR CARE FOR VFR FLT FOLLOWING.
