Arecibo Success
by Stu2 19 Apr '10

19 Apr '10

I've only seen RX reports, so far. I was successful working KP4AO and it was quite a thrill for me. The first day, signals were weak. I didn't copy them on USB, but was able to hear them about 40-50% on CW. I called and called for the entire time. (CW) We were taking down the station of W4AD (SK), who enjoyed EME. My hope was to make one last contact from his back yard. Unfortunately, it didn't work out the first day. On day 2, I set up a station my back yard. KP4AO was louder and I was able to copy USB, but the QSB always hit at the wrong time. Inevitably, I heard 599 and 'over'! When KP4AO switched to CW, I was able to copy them about 80% of the time with the QSB. Finally, at 16:25 Eastern, I worked them on CW with my 23 element K1FO yagi, TS-2K, preamp and 175W. I tried several different TX frequencies and was very persistent. The S-Meter never moved and it was like working a typical weak VHF signal. My report is at: http://www.stu2.net/wiki/index.php/MT_Arecibo Thanks to the gang at KP4AO for all their work. I really appreciate your efforts. My first QSO was on 2M with W5UN many years ago and this one was just as special. Again - thanks! 73's Stu2 W7IY

Arecibo grumble
by Bob- W7LRD 18 Apr '10

18 Apr '10

Hello I have never uttered a controversial word on this bb. This Arecibo event presented us with a fantastic opportunity. I truly applaud those who set this event up and ran it. However-the object is to make contacts, and as many as possible in the allotted time. The CW procedures were laborious, 73's, multiple calls, excessive id'ing. They needed a top notch cw op. They used SSB, CW, then JT-65. I was waiting for them to try FM. Again, I am grateful for the chance to try to participate in this event. I learned a great deal in preparing and participating in the process. Their signal peaked at 569 using a 910 with 50feet of LMR400 to a 40 el CP yagi set for LHCP. I am sure the JT-65 mode gave flea powered stations an opportunity. As I hit this send button they have 40 minutes left. They might work a few more. grumble!!

Arecibo recordings
by Luc Leblanc 18 Apr '10

18 Apr '10

Here is 2 recordings of april 17 Arecibo EME transmission received on a linear 24 elements yagi with an Icom preamp on an FT-847 60' of LMR- 400. http://www.yourfilelink.com/get.php?fid=541211 http://www.yourfilelink.com/get.php?fid=541210 http://www.yourfilelink.com/get.php?fid=541209 My first observation is while some seems to report great reception with moderate set up? i cannot say my first EME reception is Q5... When you listen the audio file put your volume up as KP4AO is way down in the noise but after a couple of try you will be able to detect some words from them. The CW recording is much better with the maximum of filtering. Conclusion:1- An LEO class satellite station does not make an EME station at all. 2- Accurately reporting a reception by ears is not an exact science... recording tells the truth without any doubts 3- My third file is giving some explanation about why my JT65B program give's me 4 EME call sign: F5BUU KU7Z K3AX IQ2CJ I will try this mode if they used it but as i does not want to be controversial i think the 4 stations that i got on my JT65B screen where probably never transmitting at the time of reception!!! Just read the third file above and you will be able to understand more my point 2! Anyway it was my first EME SWL reception "i hope" as some just tells me it is possible that tropo scater reflection in the caribbean and ducting made some getting the Arecibo signal this way as their EIRP made it quite possible explaining the rapid QSB reported by some station. Here as soon as i move the antenna off by 10 deg Arecibo disappear. Just to pointed out i was listening the HAARP EME test 2 years ago and i was able to copy their HF ionospheric signal and their moon reflected signal much much weaker but some on the world where only able to get the moon reflected signal as they where out of range form the standard HF propagation path. Just to warned those in the tropo scatter/RF ducting path from Arecibo to checked if moving their antenna off the moon make the signal disappear. P.S. If someone is aware of an audio software able to filtered out the noise from a recording just pointed me toward the source.

Preamp mounting?
by Greg D. 18 Apr '10

18 Apr '10

Hi folks, So, a follow-up to my previous message. All this discussion about EME got me thinking... We're always taught to put your preamp as close to the feed point as possible, but as with everything, there are tradeoffs. Where should the Preamp be mounted? Choices: 1 - on the antenna boom, at the feed point (or attached to the CP relay) 2 - on the rotor cross arm 3 - below the rotor, where the flex transitions to the main feed I'm thinking that #1 is a problem. Yes, it's the shortest run, but you've got the weight of the preamp at the far end of the antenna, unbalancing things. Depending on the antenna, it might be right in the middle of a bunch of elements, so putting a metal box there might upset the antenna's performance or impedance. It's would also be subjected to the strong RF fields of the antenna during transmit. #2 is probably the best; fairly short coax run on the antenna side, and somewhat outside of the RF field. #3 (what I have) is most convenient, and has one less set of connectors to go bad, and one less wire to snake around the rotor. Weather proofing is easier when the object being proofed can't move, and mounting the preamp on the tower, for me at least, is a lot easier. And, it's not THAT much more coax to the antenna. Thoughts? Greg KO6TH _________________________________________________________________ The New Busy is not the too busy.

EME
by ANTHONY JAPHA 17 Apr '10

17 Apr '10

Hi all, On a lark, I took my FT817 with ARR preamp and 8-el cheap yagi downstairs to listen for KP4AO. They were about 349 on CW around 2000Z. Unbelievable, I thought. I have tremendous noise of all manmade kinds here in Manhattan. You can only imagine how loud the noise is. Still, KP4AO was in there steadily for as long as I listened, about 15 minutes.. Another reason for my surprise is that the FT817 has no CW filter. With a filter, I'm sure they would have been Q5. Pointing the beam was not critical at all. This all reminds me of W2RS's backyard EME article of some years ago. Are you in there, Ray? Anyone out there with a spare million watt amp? 73, Tony, N2UN

With any luck we should be good for 350-400 W today. We have also located a power supply for a solid-state amp that should be good for a bit more power, maybe 500 W. 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.

Radios for satellite operations
by Jacob Tennant 17 Apr '10

17 Apr '10

Was wondering today after searching around on the internet, what radios are people using for satellite operations as I noticed the ICOM IC-910H and the Yaesu FT-847 are now discontinued? Was hoping to get into the SSB/CW satellites but was hoping to do it on a new radio, but it seems the satellite radios are disappearing from the market.

Arecibo and circular polarization using cheap yagis
by Douglas Quagliana 17 Apr '10

17 Apr '10

I heard Arecibo would be using circular polarization, but I haven't heard if it will be left or right-handed circular polarization. I also heard that there's a way to do circular polarization with the popular "cheap yagis." Apparently the details are in an article in the April 1999 issue of CQ VHF "Cheap Circular Polarization? It Can Be Done" on pages 66-69. Is there anyone on the list that has this back issue that can tell me what the method is that is described in this article? Is it a physical quarter-wave displacement on the same boom? Two booms with a quarter-wave coax delay? Something else? How is the circular polarization done with the cheap yagis? Douglas KA2UPW/5

OT-ish - anyone got FT-290 bits?
by Gordon JC Pearce 17 Apr '10

17 Apr '10

Hi all, In order to get onto the linear transponders I picked up a slight-project Yaesu FT-290 at a rally last weekend. It's pretty much working, but the display is faulty. It pretty much only ever displays a backwards F, no matter what you do. Other than that it tunes, memorises, clarifies and generally seems to behave itself, so I suspect that the display IC is faulty and the CPU is actually okay. So, does anyone have a dead FT-[267]90 for spares? Really, I just need the display PCB (the LCD seems fine, so I'd take a chance on one with a broken LCD) or even just the chip. If I could find spec on the chip I'd even have a crack at building a replacement controller. Feel free to reply offlist if you don't want to noise up the list with radio fixing chatter. Thanks, Gordon MM0YEQ

AGWPE and Window 7 problems
by D. Craig Fox 17 Apr '10

17 Apr '10

Greetings all. Having only 12 el on 70cm and no az/el, Arecibo is so not happening at my QTH. But I digress. I recently went to a new Windows 7 (Intel Core I-7 processor) computer from a P4 (what a delight.) Anyway, SatPC, digipan, MMRTTY, HRD all work fine using my Signalink. What no longer works, however, is AGWPE and UISS. Unless I set the default speakers in the computer to the USB codec (Signalink), it simply will not transmit packet. Decodes fine. This is preventing me from d'ing on NO44 and ISS. I have posted this problem on some other sites but so far no useful feedback. If you are running Signalink, AGWPE and Windows 7, can we talk offline?

I'm at work and not QRV, but I had no problem copying them with a single 12 el. yagi leaned again the chair when they did the test a couple of weeks ago, and most everyone else gave them good reports. At the time, they were running 50w, a barefoot Kenwood TS-2000. They must have changed rigs if now they only have 20w. And something else must be wrong, because even folks with big antennas are having trouble copying them (more so than the 50w vs. 20w would suggest).

Re: Arecibo heard

I went home for a "lunch break" and was able to copy them on CW (but not SSB) with the following: M2 440-18 (an 11' vertical/linear antenna that claims 14.5 dBd) ARR MSP432VDG-160 preamp (claims 0.55 dB NF) TS-2000X radio, CW mode, filter width betwen 600Hz and 200Hz It wasn't arm-chair copy, but after nudging the array around a bit, I could make out characters and their call. Didn't try to listen to anybody else (assuming they would quite a bit lower). The moon was around 67 deg elevation, right in the small "hole" of the forest canopy growing at my home :) Anyhow, it was fun, and given their low output, will be fun to listen tomorrow with a repaired amp! 73, Mark N8MH On Fri, Apr 16, 2010 at 3:27 PM, Bill Dzurilla <billdz.geo(a)yahoo.com> wrote: > I'm at work and not QRV, but I had no problem copying them with a single 12 el. yagi leaned again the chair when they did the test a couple of weeks ago, and most everyone else gave them good reports.

SATPC32
by Roger Swickis 16 Apr '10

Thanks Mark, Well, I had the same position data in both AOS and SATPC32. I don't know what was happening, but it seems to have magically resolved itself. Both programs now read the same. Strange. But I think we can attribute it to RF getting into the computer. At any rate I'm glad I didn't go ahead and reinstall everything. Oh well - you don't have to be good of you're lucky! Roger VA7MG

If I get a chance to give it a listen I'll be using an auto-tracked eight element RHCP yagi with a Landwehr preamp. There was an OM in the area that was an avid EME'er at one time. He has since passed away, I asked him once when is the best time to listen for stations doing EME, Full moon, New Moon, Quarter moon, and he said new moon was worst because of solar noise and also when the sun is within your beamwidth around new moon.

There was a request on here several days ago for a 50 ohm antenna matcher, and by the time I found the file, I accidentally deleted the request... An inexpensive homebrew one can be found here: http://cid-1973adc8c1d3207c.skydrive.live.com/summary.aspx?sa=140581470 See 435QuarterWaveMatcher Probably find the parts in your junk box..... 73, Dave, WB6LLO dguimon1(a)san.rr.com Disagree: I learn....
