What we need is for some bright soul to develop a radio we can all buy
for a coupla hundred bucks that will transmit at some quiet freq every
second. Then a nice little LED in the cabin, linked to the DF, would be
lit whenever traffic is near. We have FM radios in the steel mill that
automatically transmit a morse code ident (per FCC regs) every 30 minutes.

Don't know much about TCAS, but I believe the system has a voice warning
that actually tells you how to maneuver. In any case, most aircraft
current with TCAS have two pilots. TCAS also is tracking transponder
squawks, not radio calls made at 1 minute intervals.
