Glad to be a part of this place. I've had this setup for a while, but I just got confident enough to get it public. Still needs work, but here's my very humble arrangement.
Air Band tuned J-pole, approx. 23'5", PVC mast.
The tree you can see a part of has been a bit of a problem, but we keep it trimmed back regularly. I hope to get the imposing limbs cut down soon.
My out-of-retirement laptop running the feed. I run a much faster desktop next to it which is a backup in case of a crash.
And finally, the BC72XLT running the show. It's small, but a nice little scanner. Very easy to use.
I plan to improve as I go. I've found an in-line amp/filter for the Av band that I plan to get soon. I also may move to a more powerful desktop scanner at some point, but for now this rig works great.
