More great FO-29 passes
by w6zkh＠comcast.net 29 Jan '10

29 Jan '10

It sure is nice to have FO-29 back online, after being off for awhile. The 0415 utc 2/29 pass provided my first QSO with VE4AMU and this last pass of 1602 utc provided a contact with Larry, WA6DIR. This last pass was out over the Pacific. (I missed the 1416 utc pass; was still in bed). I hope it stays active, but do know it is in a test phase. John W6ZKH

ND9M Road Trip Update #3
by claryco＠aol.com 29 Jan '10

29 Jan '10

Yesterday's snowfall in SW Kansas complicated road conditions and especially safety so I opted to hold off getting to the DM98/EM08 line until today (Friday). I'll operate from that line during the AO27 pass that starts at about 29/1950Z. Depending on accessibiltiy, I may get to the quad grid point and add DM99/EM09. >From there, we'll head north to Nebraska and put out DM99/EM09 during the AO51 pass at 2236Z and then either put out the DN90/EN00 grid line or the DM99/EM09/DN90/EN09 quad field point on the AO51 pass starting at 30/0014Z. We have to focus on getting to Denver now, so time permitting, Saturday's game plan will be to hit the DN91/EN01 line on AO27 at 30/1922Z, stop again in DN91 for the second AO27 pass at 2101Z, and then the DN80/DN81 grid line on AO51 at 30/2335. After that, we'll be in Denver (DN70) and Cheyenne (DN71) with family for a few days before heading south through NM and into TX. 73 for now, Jim, ND9M / VQ9JC Wekeeney, KS / EM09

DK7ZB 435MHz aerial question
by Phil 29 Jan '10

29 Jan '10

Thank you for reading this. I'm in the process of setting up my satellite station after a five year break and my UHF aerial doesn't seem to be performing as well as I expect it should. I always suspected that it's performance was below par. AO-51, for instance, is received no better than strength 3 on my FT-847. The aerial is a twelve element design (twelve elements in each plane) by DK7ZB and is without a doubt the best 435MHz aerial that I have ever built. The extra twelve elements have been removed for testing purposes and is currently hand held and rotated as accurately as possible. I suspect that the poor gain might be due to the matching system because I was always unsure of the exact physical length of parallel quarter wave matching cable. The element lengths are spot on and the element spacing is within a millimetre of the design figures. The SWR, even after all this time, is still around 1.2:1. The Belden 9913 cable connecting the aerial to the radio is only nine metres long and, as best I can tell, has a about a half DB loss. I would like to make e-mail contact with anyone who may have built this aerial or one of the other UHF designs by DK7ZB. -- Regards, Phil

updated pseudo moon keps
by Bob DeVarney W1ICW 29 Jan '10

29 Jan '10

Here is a set of pseudo keps for the moon calculated using the MoonKeps program by HB9BNI ( thank you ! ) to calculate them, and then rewritten in two line form. These work fine for my Uni_Trac 2003 using both the -2003 and the -2000 software. Perhaps they may help someone else with a stand-alone tracker like mine. Cheers, Bob W1ICW MOON 1 00000U 00000A 10019.90529622 .00000000 00000-0 00000-0 0 0004 2 00000 25.1631 348.5977 0637000 142.8591 221.8486 00.036600996 6

FO-29
by David - KG4ZLB 29 Jan '10

29 Jan '10

So nice to hear FO-29 booming again on this last pass at 00:46, really strong and loud - congrats to the team on getting this one back in shape, very much appreciated! And hi to VE4EMU who obliged me with a contact although I lost you completely after the exchange! A couple of others on as well! -- David KG4ZLB www.kg4zlb.com

To determine my exact uplink frequency in order to be translated by AO-7 at 145.940 MHz +/- at the very AOS moment when the bird comes to me from South to North during an ascending orbit it was also very important for me this night because in the following days I plan to contact on skedule at 145.940 +/- MHz the friend ZS6BB, Pierre in KG43EU But what was really happening this night ? You are right ! The distance into free space between AO-7 and FO-29 was about 1500 km at 06:15 UTC and both satellites where in mutual covisibility so that my 145.940 MHz CW signal that was translated by AO-7 was received by FO-29 and retranslated by FO-29 in 435.840 MHz at 06:15 UTC when you received my CW signal in Pretoria KG44EE through two satellites ! In more details at 06.15 UTC the subsatellite point (SSP) of AO7 was over Nigeria at 8.557° Latitude North and 10.095° Longitude Est and his footprint was not completely covering ZS land while the SSP of FO-29 was over Zaire at 6.482° Latitude South and Longitude 16.500° Est but his footprint was fully including ZS land where you was able to receive me in KG44EE The above demonstrates that when the footprints of two satellites about overlaps a two way QSO between two satellites is possible particularly on CW provided that the uplink and downlink frequency bands are the same and one station transmit to one satellite in 70 cm listening in 2 meters while the other one transmit to the other satellite in 2 meters listening in 70 cm Unfortunately this is not the case betwen AO-7 and FO-29 because the 70 cm bands are different 435.800 to 435.900 MHz for FO-29 and 432.125 to 432.175 MHz for AO-7 so that only one way two satellite link is possible as you Hal experienced because the same 2 meters band is in common between both satellites. The above reception of my signal by you via FO-29 also demontrates that actually FO-29 is working very well after a very long QRT because it was so sensitive to receive my signal in 2 meters via AO-7 and retranslate it into 70 cm with sufficient power to be received by you in 70 cm in Pretoria South Africa By the way since you in KG44EE are very close to Pierre in KG43EU I am confident the at the end of testing and try with Pierre via AO-7 I can try a QSO via AO-7 as well with you and I will informe you about if you agree. The distance from my JN70ES and Pierre in KG43EU is 7548 km and with you in KG44EE is 7511 km both no bad distances from South Italy and South Africa via AO-7 Best 73" de i8CVS Domenico
