L SSB / U FM report
by Andrew Glasbrenner 23 Sep '08

23 Sep '08

I worked VE3NPC this AM with good signals both ways and heard VE2DWE in the noise occasionally. Tuning is quite fast, and was done by hand here, mainly because I did not have the proper modes and frequencies loaded in SatPC32. The audio could be brought up some, and we'll look into that. Plenty of radar pulses this morning too. 73, Drew KO4MA

AO-51 mode L>U and SSB>FM report
by Rob Hardenberg PE1ITR 23 Sep '08

23 Sep '08

Hi All, At 19:40UTC today I tried the mode LU pass on AO-51 over europe. At first I couldn't hear my SSB uplink signal on the downlink so I switched to CW. That worked. I noticed that the audio level on the downlink was very low. My 23cm signal level at the satellite must be good because mode LS is working OK. Heard my CW signal on the downlink from 4 degrees el AOS to 3 degrees el at LOS. Hrd also one other station trying with CW dits/dots and heavy 23cm radar signals. Station: Uplink: IC-910 10W and 26el yagi Downlink: IC-910 2x16el Yagi 73 Rob PE1ITR http://www.pe1itr.com

Not much to report, but I did swap a brief e-mail with one of the command ops for AO-27. They are working on getting the satellite back up, and will post any updates on www.ao27.org. 73, Drew KO4MA AMSAT-NA VP Ops

Is SEEDs Off line?
by Mike Ryan 23 Sep '08

23 Sep '08

Hello all, Has SEEDs gone dead? I have not heard it in 3 days or so now and normally it is very strong here. I know my antennas are still good because I still here AO-51, SO-50 and other birds fine. The Keps I use are: 1 32789U 08021G 08123.12010393 .00000728 00000-0 10000-3 0 221 2 32789 97.9951 183.1430 0014145 286.1272 73.8374 14.81365032 582 Mike WB1AAT

2 meter KLM long boom X polarized antenna fs
by mike Kana 23 Sep '08

23 Sep '08

Greetings all Ive finally decided to sell my KLM cross polarized 2meter antenna - was originally used for OSCAR 13 and also for a school contact to the shuttle Discovery. This was garage kept and only brought out for operating - aluminum is clean - one of the black plastic insulators for holding a driven element is cracked. $90 pick up in Grayslake, IL. thanks Mike AA9IL

Re: AO-51 LU Mode
by Henk, PA3GUO 23 Sep '08

Hi Luc, Ron, I tried this new & exciting mode this morning. Since the downlink is on 435.150 I had to change the 70cm antenna from RHCP (fixed) to LCHP. During the weekend I started that but was not able to finish it. This morning I connected a coax to one of the dipols of the Cushcraft 2x8 cross yagi, but most likely that was done too much in a hurry as I did not hear anything via that beam. My groundplane antenna did pick up the downlink, but not noise-free. With that set-up I could not detect any voice/audio on the downlink, also not my own signal. I tried both USB and CW, and used on top of automatic doppler correction also manual uplink tuning (XIT knob on the TS2000x). Well, I think I need to continue to get my 70cm RX in place for both RHCP and LHCP (switchable). Dom, I8CVS, provided me the diagrams, which are similar to what I have made for 2 mtrs, so I expect no issues, apart from running out of time ... Anyway: after this SSB uplink we have a few days the FM uplink on 23cm active, another great opportunity ! Looking forward to more reports via this group. Henk, PA3GUO TS2000X 23cm uplink; 10W, 35 elements Tonna

AO-51 LU Mode
by Rm2642＠aol.com 23 Sep '08

23 Sep '08

Can't hear users very well on AO-51 LU Mode. U band downlink exhibits good quieting of squelch with some QSB. For downlink I'm using an M2 436CP30 polarized yagi with SSB SP7000 pre-amp. I might have heard a whisper of somebody today during a high pass over California. Maybe if I had a polarity switch I could hear better. de Ron n6paa **************Looking for simple solutions to your real-life financial challenges?

Henri Congratulation on your 5000 qso on AO7 and your smooth fist. It's great to hear a AMSAT NA LM 1750 from across the pond. 73 Joe K3SZH Amsat 3788 ____________________________________________________________ Click to begin your health care training online.
