Dear Gang: I am looking for a Ten Tec model 208a audio filtre. Need it to go with my Ten-Tec ARGO 515 QRP rig. Willing to pay truly high dollar for one. Anyone have one you will part with? Here's hoping to hear from you soon. 73, W.D. (Doc) Lindsey dock0evz at earthlink.net EarthLink Revolves Around You.
