Congratulations on being a new father! That is quite the experience. I have a teenage daughter and is also an experience :-) I started in GMRS about a year ago and shortly thereafter got my technician license. Curious as to why you want to put up a GMRS repeater? I had thought of that also, but ultimately never have. Talk with family, friends (licensed), neighborhood or just plain old geekiness. I thought of doing it for family and geekiness myself! remember talking to someone that I had started noticing cool areas where one could mount an antenna for wide coverage. If you want, email me at my ham call sign @gmail.com for some additional information.
