You don't even need a switch.

Assuming both stations are operating unassisted, with all databases updated
and no need to access the Internet during the contest, you could simply use
Windows to assign a fixed private IP addresses to each computer, then use
an Ethernet Crossover Cable
<http://www.amazon.com/Belkin-CAT5E-Crossover-Cable-feet-Red/dp/B000067RFT>
between each pair of computers, or use a Wireless Ad Hoc Network
<http://windows.microsoft.com/en-us/windows/set-computer-to-computer-adhoc-network#1TC=windows-7>
for
computer-to-computer networking.

e.g.

75m:  192.168.0.1 <===> 192.168.0.2   Broadcast address 192.168.0.255

15m:  192.168.0.1 <===> 192.168.0.2   Broadcast address 192.168.0.255

(The IP addresses can be same since, with nothing more than a crossover
cable, the two computers can only see each other).
