We could only be QRV for one day, saturday on the second leg. The conditions were extremly good with iso-polarized signals between the europeans for at least half of the pass. Our moonrise SSB echoes were fantastic, the best I have ever heard. We started building the portable station in misty weather at 10 o'clock in the morning and were almost ready about 1 hour before moonrise. Then I realized that the 432/28 MHz converter for my LINRAD receiver did not work. Without the proper measurment gear it was just impossible to cure the problem. We had to use the old FT736, which is not what you want when you are used to monitor a 90kHz wide spectrum, click on the wanted signal and set all possible filters for convenient reception. After a few hours of operation there was a flash-over inside the cavity of the GS35b amplifier and it took another hour or so to change the teflon sheet that should have prevented those bangs. Whilst operating I tried to set up LINRAD for audio bandwidth operation directly from the FT736 speaker output but I had difficulties to access the right soundcard in the computer. However, I manged to get things working after a few hours of trying. I guess we spent too much time on repairing things... We worked (only): utc call 14:50 vk3um 16:54 dl7apv 20:53 oh2po 21:18 hb9q 21:25 g4rgk 22:12 dk3wg 23:05 n9ab 23:23 g3ltf 1:20 sv1btr 1:30 ea3dxu (2 yagis) 2:37 kl6m Heard in QSO or sending us QRZ: sp6jlw nice signal rw1aw dj6mb always loud, but never hears us. We had perfect echoes at the time dl9kr sri Jan, didn't come round to work you jl1zcg they definetly have a receiving problem df3ru k4eme called you for a long time sm3jqs yu1ev oz6ol dl9jy k0rz always difficult f3vs fr5dn nice signal Phil. We could have worked but you were always in QSO. Again the activity was poor. Only 4 US stations heard. I think this is very sad and maybe a consequence of heavy commercial pressure on this band. If we do not use it, we will loose it. Looking at the reports, it seems that people move on to 1296 MHz. If you have to set up a portable station every time you like to work some EME, the lack of activity is certainly not a motivating argument. This is a club station and a high power amplifier for 1296 is definetly out of the budget, neither do I have the mechanical skills to build one. So we will have to see what the future brings. Thanks for everyone working us. Rig: 4x8,5wl horiz., open "tube" feed, GS35b amp - all homemade. More details to come on our website http://www.dl0ger-eme.dd8il.de/index.html 73s Daniel, DL3IAE
