[CTSARA] [GNARC] Projectsand Activites: AnIdea and InformalSurvey

[Dr. Jon Shapiro]

Why dont you guys use the repeater that is there. I have it on for hours 
this week end ( prompted by these emails)  and hear a few key click at the 
most.

Its hard from the thread whether you all want to link the repeaters, or come 
up with some innovative new system.

If the repeaters are tied up on I95 for one big long rag chew so you can 
drive from New Rochelle to Bridgeport, ... use a cell phone. Its cheaper and 
clearer.

The repeaters should be  for local use to get local help ( drive assistance, 
local info, emergency), . If no one is monitoring each repeater, as is done 
for groups such as ECARS  ( 7255 khz) which is on for 8 hours a day, then 
the repeater is just a toy to be saved for emergencies... what is the tower 
wind rating? Hurricanes anyone. The only one I ever hear and/or  talk to on 
the Stamford Repeater  regularly is John Sabini.
