Thursday Feb 4th about 5:30 PM Pacific time (i.e. just before sunset 
local time) I successfully exchanged two APRS messages with  WB8SKP-2 in 
Kentucky from my mobile in Los Angeles, over a path of about 1700 miles 
(2700 KM).

I was running about 50 watts peak output from my FT-857 into a Yaesu 
ATAS-100 mini-screwdriver ant mounted on the trunk lid of my Jetta TDI, 
on 30 meters 10.149.700 Mhz.     The narrowband PSK mode is incredibly 
more effective than conventional AX25 FSK from a weak mobile!     One 
message acked after only one transmission. the other took three tries.

Next week on my trip to Las Vegas for the Wireless Communications Expo, 
I will using my big high-efficiency W6HIQ "Hi-Q" screwdriver instead.  
Hopefully more contacts if HF propagation cooperates!
