Yes,

I'd like an easy cure, and hope this is it. I have not heard =
solid-sounding reports on here confirming it though?? Please advise.

But in my dim thinking, I don't understand the principle involved with =
the 2.8kHz filter. A transmitted carrier passing through a crystal =
filter skirt is strictly a function of amplitude and not of frequency. =
So how can it possibly be that it affects the chirp at all, since the =
very definition of chirp is a frequency change?

I'm sure that my thinking is just too simplistic here, but it does =
trouble me some. If any of you care to "halucinate" me about this please =
feel free to insult me here!

Thanks again & 73 in 99,

Roy     K6XK....CHIRP, CHIRP CHIRP!    click, click, click!
