I've got a Ten-Tec #285 filter for sale, 500hz 6.3Mhz i.f. for all the rigs from Corsair thru Omni 6+. This is one of the later filters that Ten-Tec made with a completely sealed metal shield. I'd like to get $75 plus shipping for it with payment by PayPal (no fee transaction only). Please email me off list. Thanks & 73, Barry N1EU
