I do\nlook forward to working S-band on P3E, and hope the Eagle team will \nreconsider, and fly an S transmitter, even\nif it is considered a backup or emergency transmitter.\n\nI understand why the team wants to drop it, but I have a feeling that if we \nDON'T fly it, we'll wish that we had. Sort of\nputting all the eggs in one basket to depend on U/v to work for the life of \nthe bird, isn't it? Remember AO-40 - I never\nheard the S1 TX, but aren't we all glad there were two S transmitters \naboard?\n\nI DO look forward to working U/v on Eagle, but I doubt that my budget will \nallow experimenting with new\nmodes such as C-band anytime soon. With this in mind, as far as I'm \nconcerned, Eagle will be a U/v bird only.\n\nWhile I won't argue that the 2.4 GHz spectrum is a 'sewer' in some areas, \nI've only had serious QRM on one occasion. The\nradar pulses or spread spectrum noise was cured by my radio's Noise Blanker.\n\nOne evening while copying AO-40, the bird's signal dropped completely off \nthe S-meter. It was like my dish had fallen off the\nroof or something! Seems a neighbor down the street got a new 2.4 GHz analog \ncordless telephone, and (you guessed it)\nshe was the dreaded full duty-cycle type - a high-school age girl!\n\nHer phone must have broken or was returned to the store soon after (WHEW!) \nI never got a chance to DF it, as I only heard it the one time, but was in \nabsolute\nhorror at the possibility of losing my S-band RX. For those of you that \ndoubt a non-licensed device can swamp your new downconverter, believe me,\nmy AIDC 3731 could hear nothing else.\n\nOn a related subject, seems like I read somewhere that some C-band \nexperimenters were considering using\ns-band units for the final conversion from 5 GHz? In other words, the C-band \nconverter would only need to\nconvert from 5 GHz to 2 GHz, and let the surplus s-band units do the rest? \nAnyone know any more about this\nsubject?\n\nAnother use for S-band converters might be for RF linking purposes? A small \ntransmitter and helix or dish at each end should work well\nfor control links or linking repeater sites maybe?\n\n73,\n\nKyle Yoksh\nKØKN\nOlathe, Kansas\nAmsat # 35249\nVUCC Satellite # 150\n\n", "attachments": [] }
