There will be a special event station set up and operating in Reno, NV this
weekend for EMCOMM West. The station W7ECW will be on the air for as many
satellites as can be accessed. If you need DM09 or just want to say HI to
the audience of the demonstration, please give us a shout.

I have found a number of the model Galaxis Space Scanner ACU Labeled as
being made by FutureTrak Intl, and having Lockheed-Martin manufacturer
labels. These were apparently made for tracking DBS satellites from
yachts and RV's.
I saw a post a while back about a website on using these for Ham Sats.
Does such information still exist?

Since the new L/U schedule very few operators has been heard on this mode. The first day N8MH give his call sign and about 4 or 5 users are
operating when i have the sat in view.
It seems the uplink is much more critical than the past L band uplink sessions. it look like the receiver bandwidth was reduce making
frequency adjustment more critical. I know the audio level is reduce to save energy but it could explain why many seems to find it is
harder to get on the right uplink frequency?

Reading the AO-51 book by Gould where he discuses the L band requirements. For occasional contact 150 W EIRP is needed. For superior performance 1 Kw EIRP needed. Assuming I start out with 10W to a 16 turn helix 40 feet away. Guesstimating- 5-8 W at the antenna, helix gain 8-12db. Guestimated EIRP about 40W (worst case). Am I figuring this correct? If so then AO-51 is performing better than what the book says. I am trying to "fine tune" what I have.

Greetings,
I am looking for volunteers to help out in the AMSAT booth during the 2010 Dayton Hamvention. I have a number of volunteers from the Area Coordinator pool, but could use some additonal help in manning the 6 booth spaces.
Please let me know by Wed evening 28 April if you can help out.
It makes scheduling easier if you will volunteer for two hour segments. Let me know what days (Friday, Saturday and Sunday) and what times (in multi-hour blocks) that you can volunteer and how many hours you wish to work each day.
i.e. Friday between 1-5 for two hours and Saturday 9-3 for two, 2 hour blocks with at least an hour between the blocks.
Looking forward to visiting with you at Dayton.
73,

This last pass up the west coast. Very good strong downlink, running a 910 @ 10W to a 16 turn RHCP helix through 40 feet of LMR400. Even good copy running 2 watts! Rx 40 el cp yagi. Early in the pass RHCP was better for rx, later and near LOS LHCP was better. Why? Only station heard was VE7CNA and he was very weak, aside from that I could only talk to myself. I know we have some L banders on the "left" coast and up there in KL7. It's lonely.
