AO-51 V/S MODE
by Luc Leblanc VE2DWE 28 Aug '06

28 Aug '06

My former AO-40 stuff is still working with a S9 plus 20 signal all my 2.4ghz QRM is going down the drain. Sweeping the band up and down and i notice much more less QRM from devices than a couple of month ago. I just show to one of my fellow neighbour that i can access the internet through his WI-FI router. He doesn't like my demonstration and and he shut down his WI-FI he kept only the wire function as he said after all he said his wife can access the internet from their living room where there is a wire this will free up his bed from the intenet... Just to say why so much fuss about going up keep at least a downlink on 2.4 for the next HEO birds? Just remember how many folks invest a lot of money on their AO-40 set up. I have near a 1000 QSO on AO-40 and all where conducted with stations using 2.4GHZ. I know for those who never make a single QSO on a satellite this is probably not significant enough as the wraith says they feed on us Q: Who are the Wraith? A: The Wraith are a powerful, hive-based species, who feed of the energy of living beings. I prefer Teyla Emmagan :) Thank's for the FO-29 help i found her buried in the noise of my LNK preamp in the shack as good it is on FM birds it works very bad on transponders type?

I'm trying to locate a couple of articles from 1961 editions of QST. I've ordered the QST CD-ROMs for that era, but they won't arrive soon. The Articles I'm trying to locate are: Feb 1961 - "Project OSCAR - Background" - Page 55 and 56 Sep 1961 - "Handling OSCAR Reports by Radiogram" - page 18 Sep 1961 - Tracking Information for the OSCAR Satellite" - Page 46 73, Emily --------------------------------- N1DID formerly W0EEC - CM87tm Donate to AMSAT at http://www.amsat-na.com/donation.php Support Project OSCAR - http://www.projectoscar.net Personal Website - http://www.PlanetEmily.com

Re: Shuttle Launch Frequencies
by Wayne Estes 28 Aug '06

NASA is moving the shuttle off the launch pad due to the approach of tropical storm Ernesto. I imagine that will result in a significant delay of the launch. Wayne Estes W9AE Oakland, Oregon, USA, CN83ik

Is this mode active as of today ? Nothing heard during the last path over the U.K. from 1921 to 1935. Listening for the next one... Dave. IO80SM Dorset. U.K.

Fwd: Re: Re: IARU Region 1 - Increased Amateur Sat 2 Metre Usage

I meant to type 144.100-144.170 MHz is digital EME. >Date: Mon, 28 Aug 2006 04:55:14 -0800 >To: Fabio Roccatagliata <roccaf(a)gmail.com>, i8cvs <domenico.i8cvs(a)tin.it> >From: "Edward R.

CW 2m-EME is 144.020-144.100, and digital EME is 144.100-144.700. Digital EME refers to the mode JT65 designed by W1JT which began about 2003 with JT44 (its predecessor). > >The area below 144.020 is filled with birdies nearly world-wide and useless for any "weak-signal" operation Including satellite. Just because one may not hear much local activity on those frequencies does not mean that they are not occupied by eme signals. One can point a single 22 element satellite x-yagi at the Moon and with 100-200w operate digital eme these days. The signal from such a small station are not audible but the powerful JT65 sw can dig them out of the noise. I have over 70 contacts on eme with 125w at my antenna terminals, yet you would not hear my signal if over 100 miles away from me if merely listening by ear (I would detect your 10w signal even pointing above the horizon). > >In Europe, I understand that 144-144.100 is used for terrestrial DX (tropo, ms, FAI and auroral propagation). You will not find the "weak signal" CW community willing to lose the last suband that they have (100 KHz out of 2 MHz). Satellite has 145.800-146 MHz at present. If 144.300 subband has been occupied by other modes it is due to inactivity by satellite. I would guess there is no spectrum available for satellite to move on the 2m band. > >73's Ed - KL7UW > >At 01:42 PM 8/28/2006 +0200, Fabio Roccatagliata wrote: >> >>I know the 144.000/144.035 is world-wide assigned to EME but actually >>all the EME contacts are almost made from 144.100 and above. >>Doing a research on the cluster there are no EME contacts on the segment I said. >>The newsletter proposed to use the segment 144.315-144.365 for sat >>uplink that, in my opinion, I think is more used. >> >>In any case, since the bandplan covers all the 144-146Mhz segment, I >>suppose something has to be moved away if a sat reassignation >>frequencies has to be made so the question is: Which segment is more >>suitable for that ? >> >>73 >>Fabio >>IZ1EGT/F5VKV >> >>> Hi Fabio, IZ1EGT >>> >>> Unfortunately I cannot open the page >>> >>> > http://www.iaru-r1.org/Newsletter_43a.pdf >>> >>> Glad if you or Trevor can send to me the above 43a.pdf file as an >>> attachement. >>> >>> Anyway according to the actual 144-146 MHz Bandplan IARU Region-1 >>> the segment 144.000 to 144.035 MHz that you propose is used world-wide >>> for 2 meters EME (SSB & Telegraphy )...........WOW ! ! >>> >>> 73" de >>> >>> i8CVS Domenico >>> >>_______________________________________________ >>Sent via AMSAT-BB(a)amsat.org.

echo
by McGrane 27 Aug '06

27 Aug '06

I should explain my setup here; FT8800 dual band FM rig for recieve 8 element yagi with mast mounted 18 db hamtronics preamp 25 feet of 9913 coax I use narrow fm mode for maximum sensitivity. Whoever claims that leaves on trees attenuates UHF is correct but taking this into account I base my observations on clear path passes. I liked bruningas idea of reduced duty cycle or on time of the downlink. My experience with so-50 is that people would adapt to it quickly. A good way to save energy. One shouldnt correllate transmitter current draw with solar panel output current as the transmitters are not on for the entire orbit. This brings me back to the battery issue: How many cycles are the batteries expected to deliver versus depth of discharge? Is this information available on the web? Thanks, pat
