For an ad-hoc setup.
Antenna: About 8 meters above the ground
Freq: 145.03MHz
PWR Out: 35W est.
Beacon: AX25 beacon, 1 per minute (I think I annoyed some people, but eh, it's a clear channel)
From the moderate testing done (Beaconing once per minute), my range is about 4 miles (Squelch breaking), and 6 if I open the squelch, and listen by ear for the beacon.
Pretty respectable, methinks. The antenna needs to go on a tower, though, and at that time, the Belden 8240 will get replaced with something a bit more conducive to VHF/UHF. Also, antenna is a "droopy ground plane", which works well enough, however, I'm looking to build a colinear antenna, that I see in a lot of the professional VHF installs.
I know, a lot of people are like,"4 miles! That's useless!". A 4 mile radius, however, covers pretty much all of North Buffalo, and then some (Village of Kenmore, Town of Tonawanda, and Grand Island).
Not bad... Now, if I can just get ANY BBS installed, I'm golden to start offering it to the general public for usage (Gave up on tnos and jnos, both don't seem to want to start, and can't find a Synchronet download location, and MBSE BBS is starting to irk me already).
