Some of the internet time syncing tools recommended are not compliant with Win 7 64-bit O/S. I will not be chasing those further and hope to edit the time sync service that already exists in Win 7.

I use one of the following located at my site.: ftp://bristor-assoc.com/pub/Amateur/atmtm22.exe ftp://bristor-assoc.com/pub/Amateur/atomic-clock.exe The first one allows multiple syncs during the day. The second once a day. You can Google the names and probably get newer versions, but have found these to work well and have them on all of my systems.

[amsat-bb] Re: L and S-band Options
Guy, Mode-L is not authorized for transmission FROM a spacecraft, only TO one. So you only need TX capability. Of course the rigs you mentioned will give you the needed TX capability. A cheaper way would be to find a used transverter. Note that unless it was designed for satellite use, it will probably need new crystals and tuning. In principle an HT which covers mode-L, combined with an amp and good antenna, would work for an uplink. However, the Doppler shift is so large, and changes so rapidly, that you need computer control. It CAN be done without that, but it is painful for you, and more painful for the people you might work. A helical antenna, easily made and uncritical, can be made for either mode-L or mode-S for a few dollars. Likewise, there are still a few of the old MDS converters around. AO-51 has a very loud downlink, and can even be heard on a simple patch antenna without a dish, or a short Yagi.

Is the Alinco DJ-G7T a viable option for receiving the AO-51 L-band downlink (Pricey at $320.00 but it does cover 3 satellite bands with advertised full-duplex capability)? If not (and ruling out the more expensive (and effectively non-portable) transceivers..

[amsat-bb] WD9EWK @ DM32/DM42 today, 2330-0240 UTC
Hi! Since I didn't send anything out yet regarding my trip last weekend to southeastern Arizona for a hamfest and my stop at DM52/DM53 (along with a very quick stop at DM51/DM52), thanks to all who showed up during those passes. I know DM53 is particularly rare on the birds, and a change in work schedules let me take last Friday (30 April) off for the drive to that boundary. The hamfest in Sierra Vista AZ was a good event, and thanks to all who worked WD9EWK on the 4 passes using 4 different satellites from the hamfest site. QSL cards for last weekend's activities went to the post office a few days ago, and should be showing up in mailboxes shortly. There is a window of approximately 3 hours later this afternoon where I can work AO-51, SO-50, FO-29, and AO-7 with relatively short gaps between all of those passes. My plan is to go south of Phoenix to the DM32/DM42 grid boundary and work passes on those 4 satellites starting with AO-51 at 2330 UTC and possibly stay out there through the last AO-7 pass that has LOS around 0240 UTC. I go out there periodically, and a couple of operators have recently asked me when I would make another trip to DM32. The northeast corner of DM32 is less than an hour's drive from Phoenix, so I decided to make the quick trip this afternoon. Anyone working WD9EWK from the DM32/DM42 grid boundary who would like a QSL only needs to drop me an e-mail. If you're in the log, I will get you a card. If I've never worked you before, I would appreciate receiving your QSL card for the QSO, as this location is within the area that I can use toward a satellite VUCC application - if I ever get around to filling out the paperwork and sorting the cards. :-) 73!
