Ten-Tec 217 CW filter

Overview Information
13 March 2005

Several people were asking for capacitor information on the Ten-Tec 217 CW filter. I have one I just sold so before shipping, I have pulled the values off the filter for you. I have no clue about the crystals.

I suggest you save the .jpg files for each specification page to your Hard Drive and then open and print with your favorite program that can handle sizing and such. I print with Microsoft Photo Editor. My html skills are non existent and if you just print the webpage you will likely be irritated with the output.

Asked: "Does anyone know what the characteristic input and output impedances of the 220 9MHz filter are? Or the 6.3 MHz filters?"....Duane, N9DG
Yes, I do! The input and output Z of the 220 is 200 ohms. The models 282, 285 and 288 are 6.3 mHz and have input and output Zs of 200 ohms, also. 73, Roy, K6XK

I hope this page of info will be of use to you. 73, Jim, AL7FS
