Good initiative and very instructive about all equipments at the present time used to be "hip" ;-) At this time the receive station except for some selective voltmeters like SPM3 and SPM60 ( Wandel & Goltermann), i use a FT 847 centered on 5 MHz and a converter. The mixer is a SRA-8 ( MCL) to be in front of a BPF 7 poles cheb. design, 0.2 dB ripple (i am located very near a big marine transmitter). The RX BW is 250 Hz ( optianal xtal filter). The receive antenna is a loop built with a old 5/8 coax cable (6 turns and 2meter diameter) to keep a high Q ( ~500). All this equipments are not fully finish at this time ( more on the bench like on the air!), i count on the next leaves... "To be continued..." 73: Jeff / F6CWN ( JN09TT)
