I can't comment on them directly, but when it's\ntime to try out an omni, those will be the ones I build. I appreciated\nthe very detailed diagrams about how the matching coax should be cut. I\nfelt that the other omni plans left out that very important detail -\nespecially considering the importance the phasing and matching section\nplay in their designs.\n\nI would like to report some additional progress! During tonight's AO-51\npass over the central US, I managed to clearly copy a few call signs and\nportions of a few QSOs. It is a small step from last week's work, but it\nproves to me that the fixed elevation yagi is serviceable and that I am\ngetting a return on investment. Yesterday I replaced the questionable\nRG-58 with RG-213.\n\nI have planned a few changes to the existing feed line configuration\nwhich will allow me to work 2m and 440 with seperate transceivers. I've\nalso ordered an SSB preamp for the 70cm band. I am considering LMR-400\nflex for the 70cm feed and keeping the RG-213 for the 2m feed.\n\nThe preamp was a concern for me in that since I've been working HF, I've\nfound that I receive much clearer with the preamp disabled and the\nattenuator enabled and just pushing up the AF gain. I realize this is\ndue to noise in the area and the fact that the IC-7000 preamp is a\nbroadband preamp, and generally will just increase the noise floor and\nlower the sensitivity of the frequencies I'm actually interested in.\n\nTonight I confirmed that I cannot copy any AO-51 signal without the\nIC7000 preamp engaged. Hopefully this means that with a quality\nnarrowband mast mount preamp from SSB, I'll be able to bypass the\nbroadband preamp and increase overall sensitivity of the UHF receive\nband. I know that everyone's saying that a preamp is an absolute must,\nbut I needed to clear that up before I could justify buying a preamp\nwhen in other situations, it only makes things worse.\n\nAgain, thanks for your help. I'll let you all know as soon as I get\ntransmitting.\n\nScott\nNW2s\n", "attachments": [] }
