I've found my PCAS system to be very helpful. For a fraction of the
cost of a TIS or TCAS system it lets me know when someone is nearby.
It doesn't see all traffic but it sees much more than I do.

Thanks for the tip. This is the first I've heard of PCAS.

How does PCAS work?

ATC ground stations and active TCAS systems transmit interrogation
pulses on an uplink frequency of 1030 Megahertz. Aircraft
transponders reply on a downlink frequency of 1090 Megahertz. PCAS
devices detect these transponder responses, then analyze and
display conflict information.
MRX-A (Portable Collision Avoidance System) $589.99


It sounds like just the thing for flying in the LA basin, and renter
pilots aren't excluded.


See the thread "Any pireps for PCAS MRX collision avoidance system?" from
early this month.

Less than $500... And, they have been improved so they can be connected to
your intercom.
