Anyone willing to email me a copy of the Yaesu FR50B User Manual?
"Richard" wrote in message ... Hi. I need to look at the FR50B user manual. If anyone is willing to email me the manual, please do. Much appreciated. Thanks. My email: Please remove the word "GARBAGE". Thanks. I'd really like a copy of the user manual, but if that does not materialise, anyone know the operation of the FR50B? This is what I THINK it is: It's a double conversion reciever thus: \|/RFin RF AMP---- 1st MIX ---- 5173.9 Khz FILTER -- | L.Osc (VFO) ---------------------- 2nd -----455 Khz FILTER MIX | HETERODYNE OSC (5628.9 Khz) 1st IF = 5173.9 Khz 2nd IF = 455 Khz It's the frequencies that I'm after for each band. To work them out I need the mixing details. I think the mixing details a 80 and 40m: 1st IF = L.O - RF in 2nd IF = HET OSC - 1st IF 20.40.12.10m: 1st IF = RF in - L.O. 2nd IF = HET OSC - 1st IF Can anyone please confirm this? TIA. |
