Hi Brian,

Both RELAY and WIDE have been deprecated. Their replacements are WIDE1-1 
and WIDEn-N where the latter is typically WIDE2-2 or WIDE2-1, depending 
on how many hops are desired. Smart digis trap really long routes like 
WIDE7-7 to reduce channel QRM.

This scheme, known as the WIDEn-N or new paradigm, restricts the number 
of hops a packet can take. The SSID is decremented by one each time the 
packet is repeated, and is repeated no more once this falls to 0.

Cheers ... Ray
