Does anyone know if Yaesu provides a PLUG with their FT450 radios for the LINEAR JACK? It appears to be some kind of 10-pin DIN connector... Anyone have experience using this jack to switch T-R control to a relay fo an external (non-Yaesu) linear amplifier??? Thanks & 73 - Brian, AF4K -~ø¤º°º¤ø~-"ßrÿ in FLÕRÎÐÁ"-~ø¤º°º¤ø~-
