We are having a Z meet next Saturday. There will be several people here that could help diagnose the noise for you. We are expecting well over 30 Z's. There's a few details listed in the events section. If you would be interested in attending, shoot me an email at davistj@cinci.rr.com The meet is only about 35-40 from Dayton. You could also meet several of the Dayton area Z crowd.
