i was looking at the kbuf information and it did not have any freq listed for the feed. can you tell us what freq kbuf is using.
I am not the feeder but I am a pilot who routinely listens to BUF's feed archive to critique my airborne communication skills. The BUF feed is carrying both approach frequencies on 126.15 and 126.50, as well as tower on 120.5.
AFAIK, the feed is not carrying ground nor clearance delivery. I believe this may be due to the feeder's distance from the airport. In the case of the Syracuse, NY, feed, which I provide, I am too far from the airport to receive most ground-based aircraft to make it worth including those two frequencies in the feed.
