Because the quality of Echolink (be-doop, other people's repeater IDs,
lids with no license) is not enforced to nearly the extent that it is
for IRLP.  Further feedback inline:

Can, yes.  May, no.  This is expressly forbidden in their contract
last I looked.

This is expressly encouraged, last I looked (the radio part, not the
dummy load part).  This is how Randy's node in Idaho Falls worked -
simplex, no repeater.

Exactly the same problems with waiting for the tail to drop that you
run into if you use a cross band repeater in your car.

440 is preferred due to congestion on 2m.  If you want to go all-in,
put 'er on 900 and have it be private by obscurity.  :-)

See above.

No harm could possibly come from coordinating.  The SNP is available
for experimental use and could prove fine for QRPp into a dummy load
around the house, particularly with CTCSS or DTS.  But "do I have to
coordinate" is a question properly reserved for
(which is your local equivalent of TMARC).

I would say generally that 440 is smooth sailing, 220 even more so,
and 2m you really want to coordinate.  There may not even be any slots
available on 2m.  But that's my guess, and I'm not a repeater maven.

Not if you're still on the SNP pair.

I mean well in terms of getting a radio in my car...  but I generally
hang out on 147.300, not the AMRAD repeater.

The AMRAD Tacos Teleporter so that you can make a quick trip up here
every Saturday.

I would say that generally IRLP is worthwhile and once I have the
house dealt with it's on my to-do list.
