[amsat-bb] Echo Madness
Having been on the bird on the night the recording was made (yes you can hear my feeble call sign in there a couple of times) I have to say, it was no worse than 40 meters earlier in the day with the WPX SSB contest going on. The whistles were a bit over the top. I am new to the satellites ( 3 successful passes ) so I am just learning the etiquette and procedures. It has been interesting over the past few weeks putting the station together to be able to get into the satellite. I have learned quite a bit already. The first thing I learned was that I didn't know anything about how to communicate on the satellites!!! ;-) I have enjoyed the few contacts I have made and look forward to more.

[amsat-bb] Preamp Distance from Antenna
Hi, I am in the process of getting the ARR SP432VDG preamp for my mobile setup (and just to have around), and I have read that the closer to antenna you mount the preamp, the lower noise figure you will have. My question is, what is close to the antenna – 1ft., 5ft., 10ft.? Ideally, I would probably mount it about 5-6ft. from the antenna (1/4 wave) – would this be acceptable? Any additional advice would be appreciated! Zack KD8KSN ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

Why do you need a preamp in the mobile? Most new rigs are great at sensitivity. You must also remember that if you are mobile, Intermod is just around the corner at these high sensitivity preamps.

[amsat-bb] Re: Preamp Distance from Antenna
Hi Dee, I have tried monitoring passes with the FTM-350AR, and it is just about impossible to hear anything. Granted, I was using a 5/8 wave, but I have used a 1/4 wave several times before with a different radio and experienced similar results. I will probably try it again just to make sure, but I would still like to get something to take the edge off and increase my hearing time a bit. I know a few of you here have used the ARR preamps in your mobile (or while mobile) setups - does anyone have issues with intermod?

One solution is for the experienced satellite > operators to move from the single channel FM satellites over to the SSB > birds. I generally agree with you on these points, but not completely on the point that experienced operators should move off the FM birds to the SSB birds. If all the experienced operators move off the FM birds, who would be left to help the inexperienced operators? I've heard more activity on the SSB birds lately, probably due to ND9M/MM sailing around and working those passes along with the FM passes. The increased SSB activity helped me on Saturday at the hamfest in Tucson AZ followed by my post-hamfest drive through DM52/DM53 on my way home. Three of the 4 demonstration passes at the hamfest were in SSB (2 on AO-7, one on VO-52). Later in the day, there were active FO-29 passes where I was able to make 9 QSOs on the first pass (including ND9M/MM), and 5 more on the later pass to the west. Going to a comment by WA4HFN yesterday... If there was a problem on AO-51 that required the immediate attention from a command station, by all means do what is necessary to keep the satellite in good condition. Nobody should find fault with that. From the recording posted on K8YSE's web site of the Sunday afternoon AO-51 pass in question: http://www.papays.com/sat/AO-51_27Mar2011_221636z.mp3 along with posts on here since then, it is clear that was not the case. This is exactly like the situation when K5D was on the satellites from Desecheo a couple of years ago, and the posted threat by KO4MA to shut down one of the AO-51 repeaters due to what Drew called at the time "extreme poor operating": http://amsat.org/pipermail/amsat-bb/2009-February/017442.html Since AO-51 operates on a schedule, AMSAT should keep to the schedule. It may not be pleasant to hear at times, but we are dealing with a single-channel satellite (or, at times, a two-channel satellite). There are problems from time to time, whether it is an inexperienced operator, someone using an uplink as a private simplex channel or frequency for an EchoLink/IRLP node, or whatever. We deal with this on HF, we can deal with it on the satellites. If there is a last-minute change needed in order to protect the satellite, we will understand. If a change in the schedule is needed for some reason, do what's been done in the past - publish notice of the upcoming change as is normally done and go from there. If the last-minute change is done because someone is frustrated with what is being heard, or so someone can try to work a rare station or a rare grid, that is wrong. By the way, the pass after the uplink change didn't sound very different than before the change, except for a few seconds when Drew announced the change and everyone had to change their uplink frequency. 73.

[amsat-bb] FT-60R and recording?
Hello, Is anyone using a FT-60R with their Arrow and a recorder? I use a Heil Traveler headset w/boom mic. I have not been able to come up with any way to put a micro recorder in line with that set up. The radio only has 1 jack for mic/ear phone. The FT-60R is not duplex so maybe the question is moot. The best I can figure so far is to have the recorder close to me so at least I could log who I contacted (without taking paper notes) Any thoughts appreciated, 73, Ted K7TRK ___ Sent via AMSAT-BB@amsat.org.

I wasn't aware he was doing that, but he did the same thing for some Mexican hams as he sailed down the Mexican Pacific coast toward the Panama Canal. It's great that he was able to take the additional time for terrestrial activity along with his already-busy schedule on the many satellite passes he's worked - and spending all that time on the helicopter deck! Jim's trip has been great for those of us chasing grids. I know I didn't log as many new grids as others, but I was getting a bunch as he approached the US west coast. Regardless of the number (the count is at home, maybe 16 or so), it's been great to get ND9M/MM in the log all those times - in FM, SSB, and even a few QSOs in CW.

Hi Ted, I also use the FT-60. Since it is not full duplex, I do not use headphones and just have a small recorder hanging from my neck. It picks up my voice and sounds from the radio. If you want to use headphones, I suppose you could use a T adapter and plug both the phones and the recorder into the headphone jack, but then I don't think your own voice would be recorded. 73, Bill NZ5N ___ Sent via AMSAT-BB@amsat.org.

I have often wondered about this myself. I like to use headphones... I wonder if you could use a stereo recorder, and put the "speaker out" (low impedance) to one side, and an external mic (high impedance) to the other. Getting the audio to balance would be a trick. We need a small portable, two channel mixer with low and high inputs and a balance control. Otherwise you have to use an external speaker, and just pick it and your voice up over the mic.

Let me clear something up here. I didn't change the frequency so I could work Jim or anyone else, otherwise I'd have called him after the frequency change. I worked Jim on the next FO-29 pass. I seriously resent the implication that I intervened out of personal greed, especially from you Patrick. I changed the frequency for a number of reasons. There were multiple stations QRMing the uplink with whistles, blowing in the mike, and CQs. A lot of this was before John's recording started. If you listen to the recording, no QSOs were being made, no calls getting through, NOTHING was working. Changing the frequency and asking for a little courtesy was an attempt to make things at least somewhat useful for the remainder of that pass. Considering a few QSOs were made afterwards, I consider it at least a partial success. Again, you'll notice I wasn't among them. I'm sorry a few of you missed Jim, but you likely would have anyways, as he had already decided to QRT because of the bedlam, until I changed the uplink. For what it's worth, you and Damon are the only two who've objected. At least you were moderately polite about it. Both of the "DX" stations on that pass were understanding and did not object to my action in the emails exchanged afterwards. Several others have written in support, and I only wish more would have done so publicly. I take input from everyone, and try to be out in the public as much as possible. Take a look back at the level of interaction from the previous few VP Ops and ask if yourself why they stayed the hell away from the users. So your objection is noted, but in the end, I alone am responsible for the operation of AO-51 and our other satellites. I will continue to act in the satellite and AMSAT's best interest, as charged by the President and Board of Directors of AMSAT, in the manner I best see fit, until removed or replaced. Consider we already have two open VP positions, an open BOD alternate, and a highly complex and finicky, aging satellite, before you decide to run me out of town on a rail. A lot of the users of this satellite have NO idea the hard work it takes to keep AO-51 running. I have volunteered hundreds, perhaps thousands of hours over the past several years, in order to make AO-51 available as often, and in as many modes as possible. I've left work early, went in late, postponed personal vacations, missed family events, and spent thousands of dollars to upgrade my station, in order to be able to keep it in service so we can download and process telemetry, reload code, keep the repeater running, and promote AMSAT. Mark, Kevin, and Gould have done the same. While you guys bust tail to get on the air to work a new grid, we are there on the digital downlink trying to keep AO-51 alive, hopefully long enough to see it's replacement on orbit. I'm writing schedules for SO-67 and AO-51, emailing answers to users who've asked questions, and trying to find time to spend with my family. So before you get on the -bb and take potshots at us, whine, piss and moan, you better think of the alternative scenario without a few command stations who give a damn, or without a VP Ops.

We have had differences of opinions on other topics in the past, even here on the -BB. That happens. We have exchanged our opinions, and it has been done in a calm and respectful manner. I did not call you any names, I took issue with a decision you made during that pass, in at least one of your AMSAT positions.

I know very well that it takes a lot of time and effort. I had been in the Operations Group previously, helping to answer questions that came in from users and help with preparing the AO-51 schedules. When I left that group a couple of years ago, that was when I started going out to more hamfests and other events on behalf of AMSAT. I continue to do that, and also try to do my part to support the organization financially (hoping to hear the successor to AO-51 on the air, and other satellites, in the future). I appreciate the hard work you do, and for putting yourself out here on the -BB. I disagree with what you did on Sunday, but that doesn't change my appreciation for what you do on behalf of AMSAT.

[amsat-bb] Re: Preamp Distance from Antenna
Hi Zack, KD8KSN The loss in dB of the coax cable from the antenna to your preamplifier adds directly to the Noise Figure NF of your preamplifier. As an example if the loss of the coax cable is say 0.7 dB and the Noise Figure of the preamplifier is 0.55 dB as specified by the manufacturer then the overall Noise Figure of the system antenna plus preamplifier is 0.7+0.55=1.25 dB This is why to reduce the overall Noise Figure of any receiving system it is necessary to install the preamplifier as close as possible to the antenna connector. By the way the gain of a ARR SP432VDG preamplifier is 16 dB and as connected in front of your 70 cm receiver you will see an increase of noise level of about 3 S-units in your S meter but the overall Noise Figure of your receiving system will be much lover than the Noise Figure of the 70 cm receiver alone. In this condition using a preamplifier the 70 cm receiving system will be more sensitive but it will be more susceptible to intermodulation and overloading when you transmit to a satellite in the 2 meters band. If you suffer with intermod the only cure is to add a 6 dB attenuator from the preamplifier output to the 70 cm receiver input but if you use a 70 cm tranceiver don't forget to remove the attenuator before to transmit in 70 cm I hope this helps. 73" de i8CVS Domenico - Original Message - From: "Zachary Beougher" To: Sent: Wednesday, March 30, 2011 4:24 PM Subject: [amsat-bb] Preamp Distance from Antenna > Hi, > > I am in the process of getting the ARR SP432VDG preamp for my mobile setup (and just to have around), and I have read that the closer to antenna you mount the preamp, the lower noise figure you will have.

Ideally, I would probably mount it about 5-6ft. from the antenna (1/4 wave) – would this be acceptable? > > Any additional advice would be appreciated! > > Zack > KD8KSN > ___ > Sent via AMSAT-BB@amsat.org.

The command station webpage says that transmitter is only on over Japan for command use.

I mentioned this BB to a fellow Sat user and he has joined. I think everyone should, I have found this a very usefull source of information. Plus you can reply to certain users without posting to everyone which I think is nice. Except of course when you hit the wrong button. Anyway seems some of the other forums are stale, year + old post and all. I saw mentioned here about not everyone reading this BB so I thought I would spread the word. This is a good thing right?

>> Several others have written in support, and >> I only wish more would have done so publicly. I'll just say that I was one of the several others that wrote Drew in support. I think there's sometimes a fine balance between satellite ease-of-use and avoiding congestion. Drew took action to shift the balance away from congestion, and I appreciate his efforts in this regard. 73 de Dave KB5WIA / CM88 ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] On a more positive note...
Dear fellow Satellite Ops, In contrast to the recent disastrous pass on AO-51 the other day, today it was a joy to help many operators get EK99 and ZF2AE/ZF8 into their logs. The AO-27 @ 19:35UTC and AO-51 @20:13 UTC passes were a joy to work. As a DX Station, I appreciated everyone's courtesy, good operating technique and most importantly good listening skills. I hope the newer operators got a good feel for what a busy pass can sound like but still be very productive. As many of you know I will be popping up on various satellites mostly in the afternoon/evenings. Both on FM and SSB. I cannot guarantee that I will be on a particular satellite but I will make an effort when asked. Mornings are out for me as I am out diving. Tomorrow I will make an effort to make it over to FK09. I have to rent a car a great expense (only one rental car place on the islands and they charge big bucks) to make it over to the East end for a few hours. Right now I will only be available from around 1900 UTC to 2300 UTC. This is the only time I have left unfortunately on Little Cayman. I have to check what is available. I think one AO51 and an FO29 pass, perhaps some others. I hope we will see the same discipline we saw today to allow many stations to work me in a calm and orderly fashion. I would like to thank Drew for all the hard work to keep AO-51 happy. I know it is often a thankless effort but it is appreciated by many including this operator. Finally a reminder it is very hot and very humid here. So yes I pity those that have to stand in the cold but trust me standing in the sweltering heat dripping with sweat, tuning the radios and jiggling the antennas is a big challenge too! See you on the birds. I will be going to Grand Cayman on Saturday, so plenty of opportunity to work me from there. 73, Adrian ZF2AE/ZF8 ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: Yuri's 50th ARISSat-1 transmissions
Hi David and BB, We hope to release a development version of the BPSK/CW decoding software next week. We don't have the schedule specifics of the 12 April transmissions yet. These will be posted on the AMSAT and ARISSat1 web sites when available. The transmissions on the 12th will see ARISSat-1 in low power mode, this means 40-60 secs on, 2 minutes off. It should be a challenge to find and tune the CW signal then decode some BPSK data during the short on times. This mode was developed to be used when the batteries are low or the satellite is in eclipse. We will be collecting data and information to improve the BPSK demodulating, decoding and display software. FUNcube Dongle users are encouraged to capture and record the downlink signals, then send us the files for examination. More information on where to send the files next week. Additional information should be available later next week on the AMSAT and ARISSat1 web sites as well as the AMSAT BB. 73.
