Glad to hear someone's using it!
There's two of us feeding... there's the feed with Approach mixed in, and then there's "my" feed which only has the Tower. I believe I also have the alternate Tower frequency when they operate split-tower which muddies up things a bit, but I'm not sure the other feeder has that frequency in his scanner.
Either way, have fun listening to KAPA. I had the bandwidth and the extra Pentium III (HA!) and a copy of Ubuntu, plus an old scanner... so the only cost to me was some time to build a WiFi link to the upstairs bedroom with a couple of old WiFi routers (didn't feel like pulling cable or running antenna cable to the basement) and a $10 wall-wort to power the scanner. I could have tapped off of the PC power supply for the scanner, but I was feeling lazy.
I may buy it some kind of mini motherboard DC powered "car PC" type of thing sometime and a flash drive, just to lower the power utilization, get rid of the fan noise (which on a P-III is virtually nil anyway) and put a Flash Drive in it to get rid of the spinning platter, and have an on-board WiFi chipset so I can dump the routers, but I'd rather spend the money on AvGas.
It'll eventually get rebuilt though, so I can put it in a little box in the closet in that bedroom where it can run without anyone really even noticing it's there.
If we had power in our hangar I'd just put it out there at the airport...
