Akro, I work LTV low level, the radar coverage out there is not the best, if I get you at 5000 it would be lucky. We don't have access to the ESL radar, (you may want to ask ASA why not).
Interestingly, I can see ADSB equipped acft in the cct at ESL. Radar coverage O/H ESL is around 8-9000ft. It has it's benefits.
I'm still confused as to how it is going to cost you 25k? My GTX330ES cost about 4.5k from memory. Granted I can install it myself so 20k to stick it in a hole??
P.S. I can guarantee you that if the controller saw the traffic they would have passed it to you. The rules are explicit on this, we don't sit on our arses watching these situations. If something happens, we saw it & did nothing we're in court.
