I too had the serial port lockup, and had to reboot windows to release the hold on it. The program explictly should leave the RTS/DTR alone. Once I started a scan I was never able to stop it. Doc doesn't give any help about how to set RF gain, and what the numbers mean. That would be really helpful.
I think it would be helpful to have the scan automatically add or subtract the preamp to extend the vertical range of the scan off the passband. Note that I'm not deleting the program. I will get good at using it however it works. But I notice more about the program when I'm trying to learn it. What's the most vertical skirt db's anyone has gotten and what were your input and RF gain settings to get it. 73, Guy. ----- Original Message ----- From: "Jack Smith" <jack.sm...@cliftonlaboratories.com> To: "Jerry Flanders" <jefland...@comcast.net> Cc: <k...@verison.net>; <elecraft@mailman.qth.net> Sent: Sunday, January 18, 2009 12:47 PM Subject: Re: [Elecraft] K3 Filter Plots > Jerry: > > I've not seen any setup corruption from the K3 Filter program, but I > have not tried all my K3's functions after running the filter program. > > I hope to add a web page with some details on how to use the filter > program, but my project list is expanding faster than the time > available to complete them, so I can't promise it will be done soon. > > Jack K8ZOA > www.cliftonlaboratories.com > > > Jerry Flanders wrote: >> After I used it, my K3 had been changed.
