It appears the education process did not work very well. Over 22 incidents already logged and being investigated, many involving VFR a/c not using mode C.
Yesterday a Be20 did a radical turn to avoid a no mode C a/c on climb out of LIS. Pilot tried contacting VFR to asertain level but that a/c was on an "appropriate" frequency and could'nt be contacted. Be20 asked for a radar heading to avoid traffic because could not get a visual on the VFR.
The VFR must have been above A045 due radar coverage, a unnecessary occurance for an air ambulance.
One of the safety mitigators for NAS was pilot education.
