I have some Toko front end filters that, with a little ingenuity, could be used in various radios for 902 MHz ham band conversions. They're the 4DFA-915E-10 2 pole surface mount version of the filters we've been using in the Maxtracs (which are 3 pole through hole devices). Here's a link to the spec sheet:
http://www.toko.co.jp/products/pdf/filters_dielectric/4dfa_4dfb.pdf It seems to me that one or two of these on a daughter board could replace the 3 pole unit. Or you could just solder some left over resistor leads to the main board and tack the filters to those leads. If you'd like to try it, they're $5 for a pair, shipping included. Email for payment details. If a direct message doesn't get through, try w...@arrl.net. Jeff W6JK
