Center freq of 146 MHz, 0.5 dB ripple, -27 dB at 131 MHz and -22 dB at 161 MHz with only 3dB insertion loss. Toko can be reached (catalog of coils and filters available) at 708-297-0070. I have the big catalog and it's chock full of inductors and such, Helical filters going up to 1250 MHz and down to 100 MHz.

To: ham-homebrew@ucsd.edu I obtained some spray-on shielding from a local part-supply house. It is GC electronics part no. 10-4807 and called "EMI-RFI Shield" It works very well, but it can dissolve plastics... of course, it permeates plastics that way, too... clint@uugate.aim.utah.edu ka7oei@uugate.wa7slg.ampr.org ------------------------------ End of Ham-Homebrew Digest V93 #146 ****************************** ******************************
