Been a while since I posted here, but I just noticed I don't seem to be picking up the ground side too good right now. Does anyone know how long it's been like that? I can't remember if I tried the antenna in all possible positions or not. I wonder if rotating it would make that much of a difference? I really want to get a second antenna and 3rd scanner to split up ZNY/KWRI feed. Does anyone have any suggestions for the best antenna to pick up the ZNY and KWRI frequencies?
On another note, if you notice problems with the feed, please try to send me a PM or reply to this thread, because I don't check this forum all that frequently. I do check my emails regularly, so the email notification will tell me there's something wrong, and I'll get back to fixing it ASAP.
Rotating that antenna is unlikely to do much of anything, John. The issue is more likely a local noise level issue - something that could take a lot of debugging and that may not be easy to cure. It could also be a change in setup on the base station (ATC) end. They've been revamping a lot of equipment - and depending on a number of factors it could have made things more marginal. If I recall that signal was right on the edge anyway.
From this vantage point it is all guessing. Those broadband antennas are not ideal for optima ATC reception. Better to use one tuned for VHF airband - but even that is no guarantee of picking up any particular ground station. It's all about stacking the odds in your favor.
