Logistics does play a role here. First, yes, single frequency, the
normal APRS 2m channel. I have one portable APRS station, which will be
at net control. Connected to a projector and big screen, it displays all
the rest stops, SAG wagons, etc. There are even a few participants using
trackers that may be displayed. A portable mast is set up giving an
antenna at about 20 ft. There is almost no other digipeater coverage
natively to this area. We are hoping for at least one other portable
digi to become available to be located in another area to supplement
coverage. It's partly political as well. We've been trying to get
someone to put at least a digi, preferably an iGate at the repeater site
which has coverage over the entire course area, but have gained little
traction in that endeavor.
I shall start studying Direwolf digi configurations.
Thanks,

Assuming you're only running a single-frequency digipeater (not cross-band), I would recommend using DireWolf as the digipeater, and check its documentation for the setup. It will be able to handle the zero-delay expected of a digipeater, and will be more responsive.
YAAC can handle digipeating probably more flexibly that DireWolf, but it doesn't have the timing control over the CSMA/CD aspects of the modem that DireWolf has that will improve RF network performance.
One important question, though: do you need the digipeater co-located with the Net Control station, or do you need it elsewhere for best coverage extension? For example, I have worked several bicycle events where the Net Control station was at the geographical end of the territory to be covered, so a digipeater there would add no value (if the digipeater there could hear it, so could Net Control); digipeaters in the middle of the territory (distant from Net Control) were far more valuable since the only APRS receive stations were Net Control.

Subject: [yaac-users] Digipeater - YAAC or Direwolf?
We are going to use APRS for an upcoming event, so I will be setting up
a portable station at the event control center to display the APRS users
on a big screen. I also want to use that station as a digipeater, as
digi coverage in the area is poor. I've not fooled with setting up
digipeaters before, so all is new to me.
The portable station will be using either a RaspberryPi or Quadra
computer running YAAC and Direwolf modem. Is there a configuration for
YAAC to handle the digipeat function, or should that be set up in
Direwolf? Any good guides or tutorials?
Thanks
