[amsat-bb] Re: moon bounce
If you are a EME beginner, contact a mega-station; I suggest W5UN. He has something like 800 elements total in multi yagis, and polarizations. For beginners, unless you have been doing lots of weak signal tropo, that is your best bet for 1st EME contact. And for certain, get on the moon-net mail list. Good luck. ~Larry W7IN On 6/4/2011 1:57 PM, Bill Dzurilla wrote: The AMSAT board is not the best place for info about EME.

Join now to support the amateur satellite program! >Subscription settings: http://amsat.org/mailman/listinfo/amsat-bb Jerry, By your questions it appears you are interested in finding out more about eme (Moonbounce) but do not know very much about it. On 2m eme is conducted in the 144.030-144.100 sub-band for CW, and on 144.100- 144.160 for digital eme. Psk-31 is not used and not really suitable. A mode called JT-65 is used for digital eme. It is a narrow-band FSK mode using software and computer soundcard to drive a SSB 2m radio. An excellent article on eme is in the current ARRL Handbook written by Joe Taylor, K1JT, author of JT-65. This will answer many of your basic questions on what eme is and how to get started. http://physics.princeton.edu/pulsar/K1JT/ http://www.n1bug.net/operate/emebasic.html http://www.vhfdx.info/jt65bintro.html One cannot decide today I am doing eme. Where do I transmit? If you have a good satellite or terrestrial 2m yagi and at least 150w you have the basics to start. But there is a lot to learn before one should expect to work eme. There is the basic station setup. Tracking the Moon. Frequencies and procedures used. As you get into it quite a bit to coming up the learning curve. Give yourself at least a couple months to accumulate this knowledge so you are better equipped to try eme.

[amsat-bb] Re: moon bounce
JT65B is what is commonly used on both 2 meters and 432 MHz, however many stations use CW as well. In the microwave bands, with a large station, SSB is possible. Search for the WSJT program and I'm sure you will find lots of information. The frequency range commonly used is the lower portion of the 2 meter band, below 144.200. Moon bounce with circularly polarized satellite antennas is not very easy as almost all EME stations use either horizontal or vertical polarization, so using circular polarity will add additional loss, although I have made a couple of 432 EME contacts with my M2 circularly polarized antenna and just 50 watts from my TS-2000. However those contacts were with some very big big-guns, but don't let that discourage you! 73 de Sebastian, W4AS On Jun 4, 2011, at 1:37 PM, jerry wrote: > Is this a good time for EME comm. ?

The antenna for 144 MHz moon-bounce work is a 160-element collinear on a polar-mount.The final amplifier uses a pair of 4CX250B tubes." Also I am looking at The EIMAC publication AS49-11 IDEAS FOR EME ANTENNA ELEVATION DRIVERS Fig.4 " K1WHS found this Quasi-Polar mount in a surplus store.With a little ingenuity an elevation drive system can be developed around what can be found in junkyards and surplus stores" Sorry I got not the chance to contact you off the moon in 144 MHz early between 1977 to 1980 because I was involved in 432 MHz EME but you can see the photograph of my EME array 16 x 21 element yagi depicted into the EIMAC document AS49-20 THE MOONBOUNCE GROUP PART-3 The actual situation in 432 MHz here is very different because early in 1977-1980 the 70 cm band was very clean without the RF pollution even 20 km away from the city of Naples where I leave. In 1976 I was able to receive the EME SSB and CW signals transmitted by the 40 meters dish of Menlo Park California WA6LET only using a 4 x 20 element yagi and a preamplifier just with a BFR-90 bipolar transistor. Actually I was not able to receive Arecibo KP4AO because in 432.045 MHz there is a digital spurious digital signal here with more than 10 dB over the noise in my receiver. What difference here from the early EME pioneering days ! I am very happy to know that you are still into the EME trench with great success. Actually here near the city of Naples only the satellite operation is possible and EME is marginally possible going from 1296 MHz and up.

I tried the same thing with one of my FO432 11 el beams handheld with a bare FT817 this afternoon. This was right after getting home from the VHF Conference in Connecticut. I could hear KP4AO very well on JT65 right out of the speaker. My XYL heard the tones 25 meters away while she was raking leaves in the yard. I handheld the antenna . While at the conference we experimented with small yagis and a preamp. KP4AO was pretty good on a 7 el wood boom yagi, weak on a 3 element yagi, and very weak but audible on just a dipole. The kicker was when AF1T produced his di-pickle, which was a feedpoint with a small pickle on each side that approximated a full half wave on 432. KP4AO was barely detectable on the pickle antenna.

Keep your fingers crossed... we *should* be 10-13 dB louder today. Operating plans for today: SSB at first, then CW. As before, we Tx on 432.045 and Rx on 432.050 - 432.060. If we exhaust the CW pileup we will go to JT65B. In JT65B mode, KP4AO will transmit first on 432.045. Please call us between 432.045 and 432.049. Expected QSO pattern will be like this: 1. CQ KP4AO FK68 2. KP4AO K1ABC FN42 3. K1ABC KP4AO FK68 OOO 4. RO 5. RRR 6. 73 (... tail-ender...) KP4AO G4XYZ IO83 7. G4XYZ KP4AO FK68 OOO ... and so on. We will not send 73s; please feel free to call us following our "RRR" transmission, as G4XYZ did in the example above. On Sunday we may work any mode, depending on available activity. We will certainly be on JT65B for at least half of our Sunday moon window. Remember: please limit yourself to one QSO with us, regardless of mode. 73, Joe, K1JT ... for the KP4AO team ___ Moon-Net posting and subscription instructions are at http://www.nlsa.com/nets/moon-net-help.html ___ Moon-Net posting and subscription instructions are at http://www.nlsa.com/nets/moon-net-help.html ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: Moon
Philip, When you install SATPC32, it creates a folder in the program start menu which includes numerous programs: SATPC32ISS, AOS, LISTEN, SuM, SuMLISTEN, and others. It does not appear in the program list from within SATPC32. If you can't located the SATPC32 start menu folder, take a look in "C:\PROGRAM FILES\SATPC32" for all the EXE files. SuM.EXE will be one of them. Thanks for joining AMSAT, and especially the Life Membership!

[amsat-bb] Re: [Moon-net] LVB tracker noise
Hi, I had such a problem recently on my SDR part, the one that drives the waterfall. Problem is divided into two distortions, some are narrowband spurs, others a wideband noise that adds to the reception. In order to find the causes I finally ran those components necessary from a battery (23cm transverter, FT847 and PC) and removed power for the house at all. Then I found: -> Ground loops: Transceiver and PC must be connected to the same mains connector! -> IQ mixer is now running from a 8V LiIon battery (R2Hobbies) -> I removed the external oscillator that works as an LO for the IQ mixer and use a simple 1.8432 computer oscillator there. I also found that the 3-phase-inverters that I am using for the dish drive have internal CPUs which unfortunately generate a strong spur on 144.016 and 144.020. I tried to pull them downwards but they are that awfully accessible located in the inverters so I had to give up. -> I put 5-turn-ferrit cores on each line that goes into the inverters It really solved all problems despite the spurs of the inverter CPUs which now are little bit weaker but maybe I have to mount these two units into a screened box. 73, Günter (dl4mea) > I am using and LVB tracker to control my GS5400B AZ/EL system. > I mainly use it on EME and WSJT controlling it with NOVA.

[amsat-bb] Re: Moon Landing Special Event
Excellent job control team. Greetings from EM79 using a handheld, and digital recorder without a cable I was able to copy and record the SSTV along with the voice message on a 28 degree pass. Played the SSTV data back through MMSSTV, and got several identifiable images. Needless to say a pleasant surprise this evening. Again Thanks to all involved for a wonderful 40th anniversary memento. 73 KC9NXP Mike McMahan On Mon, Jul 20, 2009 at 8:19 PM, wrote: > Ditto on the Z pass from EN91.

[amsat-bb] Re: Moon can cost less than HEO/GEO
Sometimes it pays to go on vacation (600+ back e-mail). The lunar link analysis has been done on Amsat-bb at least 4 or 5 times in the last ten years. I have a spreadsheet program that can be used for any point to point communication in space (plug in your own numbers) http://www.kl7uw.com/MROCalc.xls Since we assume to ride to the Moon with NASA (manned flight) it could be buried on the Moon with only antenna exposed (solves some of the temperature and radiation issues). Make it the emergency comm system for the astronauts like ARISS provides on the ISS (selling point to NASA). Make it a digital passband or multi-channel system. NOT a single-channel FM repeater like AO-51 (consider have the world's hams trying to use that channel at the same time!). Microwave only make sense. Maybe use the CC-rider concept from Eagle. Now it has Emcomm potential. as well. With the 2.5 second RTLT time delay text modes make more sense. Digital voice at minimum. 30 to 50w uplink transmitter would do it (play with the calculator, above). Try for 2-foot dish on the earth station. Moon gravity is 1/6 earth and no wind (light weight dish will work). Or perhaps a electronically steared panel array. Auto-tracking by carrier from NASA DSN tracking network (let them have 3-4 channels exclusive use). 73, Ed - KL7UW At 08:43 PM 7/2/2009, Greg D. wrote: >Hi Kenneth, et al, > >Would this be a good opportunity to dust off the >low data rate digital package that was planned >for Eagle?

[amsat-bb] Re: Moon can cost less than HEO/GEO
Greetings, First of all, I appreciate the efforts of the dedicated few of AMSAT that actually go out and make things happen. You don't hear "Thank you" often enough. Being this early in the idea phase, there are a lot of questions and unknowns. What frequencies to use and what the link requirements will be can all be worked out. The bigger question for me is if the moon is a good platform for an amateur transponder. No doubt it is technically doable. If the decision is based only on launch availability--It's the moon or nothing at all--then to the moon we go. But let's all understand what we are getting into. To the best of my knowledge, NASA does not now have an unmanned lunar lander mission that has been approved, although there is a lander planned in the greater scheme of things. Perhaps someone could direct me to some current information. The last I knew, the plan called for a lander referred to as RLEP-2. It was going to be a lander/rover powered by RTG's with a 1 year mission to explore Shackleton crater near the moon's south pole. The cost was going to be in the $400-$750 million range. The launch vehicle was going to have excess capacity so it was proposed that 3-4 mini satellites be deployed in lunar orbit to do remote sensing AND provide a communication link for the lander. So, if this is the mission we are talking about putting our transponder on, it sounds like we won't hear it on earth once the rover drives into the crater. Putting our transponder on one of the mini satellites sounds like a better plan. Again, I had difficulty finding current information on NASA's unmanned lunar lander plans. The last I read anything about RLEP-2 was that it was in serious trouble because of cost and was going to be sharply cut back. If our NASA host spacecraft will take care of all the housekeeping and provided free power, then a low cost transponder sounds like something we can do (although AMSAT-NA currently does not have a satellite lab--we may need to contract out the transponder work). We just need to understand we will not have control of the on/off switch (the repeater on the ISS or the Planetary Society's microphone on the Mars Phoenix lander for example). The days of getting a free launch is over, and it is too bad the Intelsat ride share idea did not pan out for us. As I have said before, I am not opposed to a transponder on the moon, I just have a lot of unanswered questions. Thanks again to the dedicated few at AMSAT that make things happen.

[amsat-bb] Re: Moon can cost less than HEO/GEO
We have been discussing building and packaging a system that is SEPARATE from the rest of the landing craft that would take up weight and not supply ANY benefit to any mission support. What if we change that to from just asking for a FREE ride to helping provide mission specific support ALONG with supplying the band width for our needs? If we could build a package that would support the PRIMARY mission and then could be switched over for our needs during or after the mission, don't you think that we MAY get a better consideration for a FREE ride for these ideas? Domenico, I8CVS, brings up a good point about IF bandwidth also. 1) How many QSOs do we want to be able to have on this? FM would be a HUGE waste of resources (even though a modulated CW beacon may be an idea to entice some of the FM users). a) 2 SBB/6 CW? b) 5 SSB/15 CW? c) 10 SSB/30 CW? 2) How much electrical power do we need to supply for each of these amounts? 3) IS it feasible to have that many or do we have to limit ourselves? Kenneth brings up good points also. 1) How LONG do we PLAN this to be usable? 2) Power source - solar? nuclear? battery (even though I don't think they would last very long, still have to consider them here)? 3) WHAT do we need to do to certify this package for flight? 4) HOW many do we need to build to get ONE certified as flight ready hardware? 5) How do we control it? 6) How complicated do we want to go? As far as the Earth station, the bigger the better as always. But anything above 23cm would be feasible EVEN for that antenna restricted home station that is becoming the norm now a days. 45 element 1.2GHz antenna: Boom Length: 144 inches Weight: 5 pounds Gain: 20dbi 3db Beamwidth: 16 degrees 52 element 2.4GHz loop antenna: Boom Length: 96 inches Weight: 3 pounds Gain: 21 dbi 3db Beamwidth: 14 degrees 45 element 3.4GHz antenna: Boom Length: 60 inches Weight: 1.5 pounds Gain: 20dbi 3db Beamwidth: 16 degrees These are figures that I have handy for antennas I already have. Each of these antennas can be had from Directive Systems for about one hundred and fifty dollars each as a kit, more if you want it already assembled. I give these as EXAMPLES to help out. Preamps and amplifiers are extra. But even those are cheap if you want to tinker some. I found a 75 watt 2.4GHz amplifier for 20 dollars at Dayton this year that would give me about half that if I run it on 12 volts instead of 26 volts. 1.2GHz/2.4GHz antennas: 300 dollars 1.2GHz preamp: 50 dollars 2.4GHz amplifier: 25 dollars sequencer: 60 dollars 1.2GHz transverter: 100 dollars (W1GHZ type) 2.4GHz transverter: 100 dollars (W1GHZ type) Misc. parts:100 dollars TOTAL: 735 dollars (+/-) This is presuming that the station ALREADY has a 2m SSB radio and no homebrewing other than putting together the W1GHZ transverters, sequencer, 2.4GHZ amplifier, and antenna mounting hardware. So cost CAN be kept down to about 1000 dollars, maybe even less than the 735 dollar figure if the station is very creative (possibly around the 500 dollar mark then). If the plan stays at using 2m and 70cms, antennas do get bulkier and harder to handle for teardown and setup. ( I know - I am preaching to the choir here...) Figures are based on what I already have handy, so I may have to add or change depending on what bands are used. James W8ISS = On Thu, 2009-07-02 at 21:29 -0500, Ransom, Kenneth G.

Hi Kenneth, et al, Would this be a good opportunity to dust off the low data rate digital package that was planned for Eagle? If I recall, it was to be multi-service and operate at relatively low s/n levels. Replace the antennas, of course, and the radio power amps. The resulting Earth station should still be quite affordable.

I realize this is still very early in the dreaming stage but it would be nice to start seeing some realistic proposals soon. How about starting with a blank worksheet that outlines the desirements and requirements.

I believe that Putting the effort into building a Moon qualified micro satellite seems to be the most economical path to take. And will provide the greatest return on our investment.
