[TenTec] Ten Tec Filter Plots

[Bill Tippett <btippett@alum.mit.edu>]

        Has anyone ever made actual 6/60 dB plots
of Ten Tec 217, 218 and 219 filters?  Or does anyone
know if they can be found anywhere on a webpage?
I need the filter plots as standalone devices...
...not measured through the radio.  Like these at
http://www.qth.com/inrad/tentec_menu.htm if you
click "Performance Curve Online" (759, 760, 761).
