[OZAPRS] VK4IE possible error

VK4GME-3 is right in the middle of it all here

It is a KPC TNC with no ui-digi

It probably does not know what WIDE2-1 does

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
