Unfortunately it was very weak using the off-center-fed dipole transmit antenna. And...there was a Doppler shift even though I was using DopplerPSK for transmit. The signal did start and stop as I started and stopped DopplerPSK transmit, so I am pretty confident I am seeing my transmission.\n\nMaybe a true ¼ whip is needed for transmit...\n\nMark Lunday, WD4ELG\nGreensboro, NC FM06be\[email protected]\nhttp://wd4elg.blogspot.com\nSKCC #16439 FISTS #17972\n\n\n_____________________________________________\nFrom: [email protected]\nSent: Sunday, March 05, 2017 10:54 PM\nTo: AMSAT BB\nSubject: NO-84 - the investigation continues\n\n\nMaking some progress....0335 UTC pass, I decoded the PSK31 beacon AND decoded W5SAT calling CQ.\n\nHowever, I failed to see my signal on the downlink again. I am using 65 watts and an inverted L for 160 that tunes for 10 meters. The thing should be working, I worked several EU stations on 40 meters with just 5 watts tonight, so it's radiating SOMETHING.\n\nI am sending PSK31 with DopplerPSK and then trying with FLDIGI, so it's not the software.\n\nI am getting power out per the wattmeter, so it's not the transmit setup. EZNEC shows a mostly cloud-warmer type of pattern for the inverted L on 10 meters, with some small gain at lower angles.\n\nMaybe I will try the off-center-fed dipole next. What are other folks using for antennas on the uplink?\n\nMark Lunday, WD4ELG\nGreensboro, NC FM06be\[email protected]<mailto:[email protected]>\nhttp://wd4elg.blogspot.com\nSKCC #16439 FISTS #17972\n\n\n\n", "attachments": [] }
