I have been given the opportunity to put up an APRS digipeater in the
Brownsburg, Indiana, area (N39.84, W086.39). The exact location is yet
to be determined, however it will likely be on an existing tower at
around 100 feet AGL. The equipment will be located in a secure
location that will not be readily accessible to me, so reliability of
the equipment is very important.
Of course, one of the considerations is whether or not a digipeater in
this location would serve the APRS community. We have good digis in
the area: KB9LTH-10 in downtown Indianapolis, N9AMN-2 on the southside
of Indianapolis, and KB9QJM-10 in Cloverdale. However, the area to the
northwest of Indianapolis is a bit lacking in digi coverage and I
think putting one in Brownsburg will help.
I need to put together a proposal for the equipment, so I'm looking
for ideas. My initial thought is that the equipment list consists of
radio, TNC, power supply, antenna, and feedline. The devil, as they
say, is in the details. Which radio? Which TNC? Which antenna?
Anything else I'm missing?
What are the group's thoughts? If you were building a new digipeater
from the ground up, what equipment choices would you make and why?
Thanks for your input.
