Does anyone have an LVB tracker locally?
by Stephan Greene 25 Jun '12

25 Jun '12

As in a reasonable distance from Northern Virginia/DC area. I am going to add automated tracking to my station (G5400B az/el rotors), probably one of the LVB Trackers AMSAT-NA sells. When I tried a rotor controller back in the AO-13/40 days, (I do not recall which controller - may have had a serial or parallel port dongle), I recall there was a problem with the signal from one of the rotors (azimuth?) causing the controller to go into a reset mode and traverse to pointing south - possible an intermittent in the position sensor. The analog meters on the Yaesu controller do not show any problems, and the rotors have been working well over the past several weeks and the just-concluded Field Day. If possible, I'd like to verify my rotors and an LVB will get along well together before making the purchase, by testing the controller with my system. I can bring the rotor and a PC to your QTH, so you don't even have to let yours out of your sight.

AMSAT-DC RE: IC-821 and SatPC32 weirdness solved

Hi Steve, Thanks for the follow up. Very helpful! Good luck in the contest!

Equipment Racks Available
by A.J. Farmer 07 Jun '12

07 Jun '12

All, I have several 42U equipment cabinets which are suitable for rack mount radio equipment or desktop type equipment on a shelf; perfect for a repeater site or for organizing your radios or test equipment. They are also good for server and networking equipment (their original intent). Dimensions are 24" wide x 40" deep, by 78" tall. I have them for sale on eBay, Craiglist, and local classifieds, but I am more than happy to donate to a club or individual that needs one. Let me know if you have any interest as they are going fast. Available for pickup in Hollywood, MD A.J. Farmer, AJ3U

Need SatPC32 troubleshooting help
by Stephan Greene 05 Jun '12

05 Jun '12

Getting back onto the satellites in prep for Field Day (and I've had my 1st QSOs on AO-7, SO-50, and this evening, VO-52 - yay!). Running into weirdness now with SatPC32 controlling the transmit frequency on my Icom 821. This is one of those, "well' I think it WAS working correctly" situations (and no I don't know what I did, if anything, to bugger it up). Or it may have always been there and I didn't notice it until I started trying more passes and closer to max elevation/max rate of doppler shift. While transmitting, when the program sends the radio a frequency correction (due to any combination of doppler and uplink tuning via the screen controls), the transmit frequency shifts 5 MHz down on 70cm (at least on AO-7, down from 435.x to 430.x) and up 1MHz (145.x to 146.x) when the uplink is on 2M. Goes back to normal after I stop transmitting and wait for the next correction, or toggle CAT control off and back on. So far, I've seen this on at least AO-7 and VO-52, and confirmed it on the FO-29 settings. Frustrating - I now have to switch off the radio control and find my d/l the old fashioned-way. Radio is otherwise responding to CAT commands normally. The RX frequency is unchanged throughout. Radio is configured in satellite-R mode, main band as d/l and sub-band as u/l. I've tried different settings of baud rate and CAT command delay without effect. I also tried a 100% uninstalling and reinstalling SatPC32 (pretty sure everything cleared because I had to reconfig the program from scratch) without stopping this behavior. Version is latest (SatPC32 12.8b), registered (AMSAT-NA of course), running on Windows7 64 (run it as administrator from my user account). CAT control of the radio is otherwise fine, addresses for main & sub bands appear correct, CAT baud rate is 19k2, and CAT delay is 70, "use sattelite mode" box is checked. Slower baud rates and longer delays did not clear the problem. RF feedback into the control cable (USB with built in serial converter) is plausible (I get some pickup on the PC speakers on 2M, full power), not sure I have a good way to test for that. Assuming I don't find and fix the problem 5 seconds after I hit "send", any suggestions to fix? The problem is very repeatable and very frustrating. Thanks & 73 Steve KS1G -- ----------------------------------------------------------------------------------------------------------------- Steve Greene ks1g04(a)gmail.com <kay ess one gee zero four>@gmail.com -----------------------------------------------------------------------------------------------------------------

Who is driving out to the Dayton Hamvention? Space Day is May 5 at Udvar-Hazy Center
by Perry Klein 30 Apr '12

30 Apr '12

Dave Sumner just delivered ARRL's operating OSCAR 1 and CubeSat models to me to demonstrate on Space Day next Saturday, May 5 from 10 - 3 at the National Air and Space Museum's Udvar-Hazy Center. We are supposed to return them to ARRL at the Dayton Hamvention. Is anyone driving to Dayton with room to carry these precious packages? Everyone is invited to Space Day. It's a good chance to see the Shuttle Discovery which will be featured. Parking is $15, but if you're willing to help with the AMSAT display, we should be able to arrange free parking. 73, Perry, W3PK w3pk(a)amsat.org

Dee Interdonato, NB2F
by Kilroy, Patrick L. (GSFC-5680) 16 Apr '12

16 Apr '12

The notice below came as a shock to me. Dee was a good friend to many fellow AMSAT members in the greater Maryland-DC area. You may leave a message to his wife Ginny at the guestbook noted below or just offer good thoughts. Dee will be surely missed by me and many. -Pat ---------------------------------------------- SB SAT @ AMSAT $ANS-106.01 ANS-099 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 106.01 >From AMSAT HQ SILVER SPRING, MD.

Dee was one of the editors of the AMSAT News Service and an AMSAT New Jersey Area Coordinator. He was the main point of contact for many amateurs as he covered most of the New Jersey hamfests on behalf of AMSAT. Dee was one of the mainstay vol- unteers for AMSAT at the Dayton Hamvention for years. He also gave satellite presentations for the clubs in New Jersey. Dee helped where ever he could, often behind the scenes. He worked on QSL duties for SAREX, ARISS, and ARISSat-1 missions so many of you have likely received a card from him. Dee was a well known and respected mentor for amateur satellite oper- tors, helping them understand the technical details and make success- ful radio contacts via satellites. Dee's other amateur radio activities in Northern New Jersey included the Bergen Amateur Radio Association, Bergen County CERT, AMSAT, and he was the treasurer of the Bergen County FM Association. Dee, and his wife Ginny, N2EYN always participated in the Dayton Hamvention and AMSAT Symposiums. Dee was the principal trumpet player for the Rutherford Community Band and a member of the Waldwick and Westwood Community Bands. He was also an avid hunter and a member of the Association of New Jersey Rifle and Pistol Clubs. Before retiring he was the supervisor of the Radio Shop of the Port Authority of NY/NJ. The funeral was held on Friday, April 13 in his hometown of Lodi, New Jersey. In lieu of flowers memorial contributions may be made to the Vietnam Veterans of America, 8719 Colesville Rd., Suite 100, Silver Spring, Maryland 20910 or AMSAT, 850 Sligo Road, Suite 600, Silver Spring, MD 20910.

Thank You in Timonium & Followup

Announcing AMSAT results of the GBHC.org Greater Baltimore Hamboree and Computerfest: THE HAMFEST IN TIMONIUM, Maryland, a week or two ago (forgive me, I just got back from a family vacation) was fantastic, in fact, much better than I imagined it would be! I offer a big THANK YOU to KEN PERKO, WA3WHE (recently retired from NASA HQ and the longtime Goddard microwave branch head, Code 567), and DAVE TAYLOR, W8AAS (longtime ARISS school contact coordinator and ground station K6DUE operator), who helped me run the huge AMSAT booth and displays. What a team! We had a really good turn out for the new one-day-only event this year. I personally had a great time. Ken and Dave claimed the same! We got to see a lot of old friends who stopped by, made some new friends, took a few photos, received a lot of donations and AMSAT membership renewals, chatted with many and showed off demos, including one of the FUNcube Dongle Pro in action on a big screen. A big hit! I expect to submit a photo or two to the editors of the AMSAT Journal in case they wish to share it widely. Let's do it again next year. Tentative date: Saturday, April 6, 2013 Don't miss it!
