Amsat Journal, Digital-only?
by Ronald Parsons 22 Apr '20

22 Apr '20

I was very pleased when ARRL made electronic copies of QST available along with downloadable copies of past issues. I could finally dispose of those magazine boxes stores on the top closet shelf. Doing something similar for The AMSAT Journal would be great. It even would allow color to be used in the articles. I seldom need hard copies of many articles, so printing has not been a problem. PDF would be my format preference. We would get the Journal earlier and wouldn't have to store the old issues. I assume AMSAT would make available an online availability of past issues. Ron W5RKN

Tuning M2 LEO pack antennas
by Carl A Estey 20 Apr '20

20 Apr '20

Recently I bought through AMSAT the LEO pack and assembled and installed it this weekend. The SWR on the 2-meter antenna is 1.4:1 from 144.1 to 146.1 with resistance of 58 ohms and 2.5:1 at 148 MHz. The 70-cm antenna has the best SWR (3.0:1 and resistance of 25 ohms) at 442.6 MHZ. Obviously neither is great. How should I tune the antennas? It appears that the only tuning possible is to adjust the shorting straps for distance from the inside edge of the shorting bar to there boom. ShouldI I be able to achieve 1.1:1 on both antennas? How should the coax be routed from the junction block? I have the LMR-400 feedline zip tied along the boom to the cross bar and then around the rotors. What suggestions do you have? The instructions particularly concerning the location of the 1/4-wave phasing line and the 1/2 wave balun were not very clear. Does anyone have any pictures or illustrations that show placement of the tasing line and balun? 73 Carl WA0CQG

Re: [amsat-bb] 23cm antenna
by Nick KE8AKW 20 Apr '20

20 Apr '20

Definitely recommend a directional antenna of some kind. Dont get hung up on polarity (Horizontal, Circular) too much. I use a Directive Systems 45 Element Loop Yagi that works nicely. The two best brands if antennas for 23cm base station sat work that are popular today are Directive Systems which makes loop yagis and Wimo which makes 23cm Helix antennas. Both work very well. The most important factor I have found with this band is to keep your horizon as clear as possible. Tree leafs or hills will heavily attenuate your signal on this band more so then 70cm, so elevate your antenna if possible that will help alot. You can get into the bird with as little as 1w if your horizon is completely clear, but if you have big obstructions like massive pine trees like I do, 10w or a bit more may be needed. It's a very fun mode to operate and tinker on. 73 Nick KE8AKW

Has anybody found a way to upload satellite contacts to a QRZ log and have them easily be confirmed? The glitch seems to be that QRZ.com wants the transmit and receive frequencies to be the same, it does not seem able to accept QSOs that were made duplex. Thanks! Bob N6REK

W4AMI Award
by Bruce 20 Apr '20

20 Apr '20

I have had a few questions and a bunch of submissions lately. I thought I would clear up some of the questions about this award. I have also updated the web page for the award with submission information. Just a little history, Robert W. Barbee Jr., W4AMI, was a very prolific operator and in his honor this certificate was created and the first certificate was issued to him on June 27, 1994. He has since become an SK and his local club has taken over his call sign. The award was originally the W4AMI Satellite Operator Achievement Award. The local club asked me not to use their call sign for the award. I changed the award to The Robert W. Barbee, Jr. W4AMI Satellite Operator Achievement Award. And here we are today, finally having issued over 100 certificates and over 30 of the 5,000 certificate. This award is for making 1,000 contacts with any station any time. You can say hello to your friend on every satellite on every pass every day and count those contacts. That being said, any contact you log counts. The award has endorsements for making 1,000 more contacts up to 4,000. Another 1,000 contacts will earn a special W4AMI 5,000 certificate. To submit for the award, please email me an extract from your log either in Microsoft Excel XLS(X) format or ADI(F) format. Either will work just fine. Then wait for me to get back to you notifying you to go online and make your payment. I need nothing from LoTW, confirmed contacts are not an issue, this award is for simply making a contact. 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards AMSAT Board Member 2016-2020 ARRL Awards Field Checker (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0100z on Echolink - Conference *AMSAT* Also live streaming MP3 at http://www.amsatnet.com Podcast at http://www.amsatnet.com/podcast.xml or iTunes Latest satellite news on the ARRL Audio News http://www.arrl.org AMSAT on Twitter http://www.twitter.com/amsat

Re: [amsat-bb] Amsat Journal, Digital-only

The Amsat-UK membership offers a membership that has both mail and digital opticion for their journal version. I live in the USA and am an Amsat-NA member but I enjoy reading other satellite news and stories. I receive their digital copy as soon as its put out. I can download it and save it for future reading and reference. They do put a water mark or reference on the first page to identify the person and source of the download. Having the Amsat Journal downloadable might be of interest to other people around the world that would like to see some of the fine articles in it. Maybe charge a fee per issue. Another plus for members could be online storage of back issues. I enjoy going back thru my stack of paper copies on a rainy day and always seem to find something I have missed or now want to try. Some members could opt for a digital only Journal maybe saving some costs and paper. Just my thoughts Mike Hoblinski N6IMF

VE8RAC on for WARD 12z-24z
by Ron VE8RT 18 Apr '20

18 Apr '20

with some breaks for meals and shopping I hope to be active on satellites for World Amateur Radio Day using the call sign VE8RAC. This will be on U/v satellites, linear and FM (making an effort to use best practices to reduce QRM), but not AO7 which is too fragile. QSLing will be through the Radio Amateurs of Canada www.rac.ca as this is there call sign not my own. A note about QSLing, for my own call sign, please keep in mind that US stamps on a SASE will not work here. If sending me a QSL through the mail a self addressed envelope is appreciated, and unless the demand gets too high I don't mind covering return postage. Otherwise unless I forget I'll return the SASE when I mail out my QSL card so that it may be used within the US. 73 Ron VE8RT, and for a few hours today only VE8RAC -- Ron VE8RT <ve8rt(a)yknwt.ca>

I've never tried below 10 watts, and even when I'm using 20 watts (which is now my standard with it), it sometimes "cuts out" in the middle of a qso.

PO-101 did not seem to hear me
by Loren M. Lang 17 Apr '20

17 Apr '20

I just tried to make some QSOs on the PO-101 pass starting around 22:04Z just a little bit ago. However, even though I could clearly hear the satellite for nearly it's entire pass, I could not seem to make it in. I'm not sure what wasn't configured right. This is my very first attempt with this satellite. I am using a Yaesu FT-3DR with an Elk Antenna. I had very clear audio for much of the pass which is usually the more difficult part from experience. On that pass, I heard: DN17 N6AJ DM05 KA7FVV K8YSE/7 DM43 WJ7WJ CN85 I'm not looking for LoTW confirmations, just if any of them heard me at all. I have five presets, all receive on 145.900 and transmit on 437.490, 437.495, 437.500, 437.505, and 437.510 MHz in that order. When pressing PTT, my radio showed the corresponding TX frequency and also TN 141.3 along with FM in the corner so I can't figure out what I was doing wrong especially during the peak when it should be close to being on frequency. I've been very successful with my set up on AO-91, AO-92, and SO-50 so it leaves me completely befuddled what I did wrong. Confused, Loren K7IW

Telemetry on 145.96 MHz
by wizardofzid 16 Apr '20

16 Apr '20

I've heard a CW telemetry signal on 145.96 (AO-91 downlink frequency) 5-10 min. before the FM pass. It's a bit hard to copy CW on a FM receiver but I've heard it 3 times in the last 2 days. Seems to fade out prior to the AO-91 pass. I expect it is an analog bird but so far I haven't figured out which. Any guesses?Rusty, WA8ZIDSent from my Verizon, Samsung Galaxy smartphone

SATpc32 -- Limit satellites to active ones?
by Thomas Schaefer 13 Apr '20

13 Apr '20

A related question…Is there some reason we need to carry old, no longer in-use, satellites in these files? This is not about the DOPPLER.SQL file but more about the lists in general as the elements files are full of objects one can never use for communications. For example, when I open the Satellite dialog, I see 200 available satellites. I have my filters setup but there is a big list of essentially no communication use—unless it comes back from the dead and the AMSAT News will tell me that I have no doubt. I was asking if one could filter the “Available” list but that looks to be just a representation of the files underneath (amateur.txt, cubesat.txt, etc). Just as we have editors for Doppler.SQL, I think one answer might be to create a new file with the active satellites in it (derived from the AMSAT satellites page). I can then use that my “Active sats” Keps file as my input. I can programmatically build the active sats file from the downloaded elements files. That seems like an easy Perl script I can put on a website. As far as a feature request (and this is purely for usability), I would summarize it thusly, add a feature where one can list the name of the satellites one wants to see in the Available file. This would be an Active filter. You can enable that with a checkbox to see active sats or all for historical reference. Then even though the program downloads the latest elements, it would only show the satellites in the active file or all if Active is not checked.

Good Contact???
by Brad Smith 13 Apr '20

13 Apr '20

<2 - A station calls me with My Call and Their Call.3 - I respond to them with Their Call & My Call/Grid> Since I am always operating handheld or portable, whether at my QTH, or roving, I cannot write the call down as it is being said, as both of my hands happen to be employed at the moment. Since a rover usually gives his grid, at least every few calls, I may say "Grid CM94, My Call" for example and the rover usually comes back at me and I appreciate that and I will then give my call and grid. Sometimes that is the best that can be done. I get his call when he comes back to me. I also record every pass on my iPhone. My memory isn't geed enough to remember 5 calls (or more, if I am roving) that I just worked, along with the activities of pointing an antenna and manually adjusting Doppler, so I rely on my recording. I know it is difficult to understand, but working portable is a lot different than sitting in front of an SDR computer screen in one's shack, with a 9700 with a speaker system and elevating and rotating, computer controlled yagi antennas. Some of us are doing this under not-so-ideal conditions. I have worked with my Arrow in the rain and in a snowstorm, several times without gloves, with noisy trucks going by and people asking me what I am doing,while trying to work. I have been asked if I am tracking animals and once as I was setting up, someone threatened to call the police. (I offered to let him use my phone, and I have Amateur Radio plates on my vehicles.) So, please cut some of us a little slack, if we are not operating exactly by "the book." Also, getting stepped on by the rude, big guns will eradicate part of the call. (Big guns are certainly more important than little portables.) If it is his/her call that gets stepped on, I can pick it up as he/she makes more contacts. If it is my call, I will email him/her to verify what my call is and make sure the contact is correct. Many times the person will thank me because he was missing one letter. Brad KC9UQR

what is a good contact?
by Ron VE8RT 13 Apr '20

13 Apr '20

maybe this has been brought up before, an alternative subject line might be "home far should you go" It seems that recording contacts and translating them into the log is acceptable. What about using post recording enhancements to pull call signs and grid squares out of the noise? A younger person with uncompromised hearing would do a better job at picking out contact information, the arguement might be made that even high end hearing aids do some audio processing. I just used Audacity to pull KJ7ATK's call out as Diawata-2 was low to my horizon, and his FM deviation was almost not there even though he had full quieting. I'll pass someone the recording if they'd like to hear it. Grid squares are required, is there an alternative other than RST? Ron VE8RT -- Ron VE8RT <ve8rt(a)yknwt.ca>

>From now on I'm just going to put my call out there on the satellite and ANY station that also puts their call out, will be considered a contact... (Tongue in cheek) I live in RI. If I try to work a station in AK or HI, I have to make sure I get their call AND grid correct, otherwise its a busted contact and a struggle to work them again. Using a recorder is good for logbook updates, but if I were to realize I got their call wrong, you bet I'm emailing them to set up a sked for a redo! It's the same thing for HF contacts... Im not here to argue, just answer a question. You're going to do what you're comfortable with. It's just a hobby - some people forget that. You didn't hear the call or grid right the first time? Work 'em again - it's moe funner that way! Larry N1MIW

Contacts with N6DNM from CM99/98 and DM08/09 grids on Apr 9, 10, 11
by Dmitry Mizin 12 Apr '20

12 Apr '20

Hi there, As I am stuck here in Tahoe region, I did a few mini roves to those grids making 131 contacts overall. All uploaded to LOTW where 81 were confirmed. I know I've worked many ops for the first time (and this sometimes true even for those who worked me before) and often other operator will make mistake with my call. So, if you do need confirmation for those grids - make sure you have my call correctly - N6DNM. If confirmations are still missing for you, email me directly with details and I will verify it on my side. Thank you all for contacts and looking forward to catching you later! Dmitry N6DNM

Efficient Contacts
by Brad Smith 11 Apr '20

11 Apr '20

< Cannot this be done more efficiently in only 4 transmissions instead of 5? > Most people do it in 3 transmissions. My call, your call, with my grid.Reply, with grid.QSL and your call. With the crowding on the FM birds, one has to get as inventive as one can. Lots of times, the QSL gets stepped on by a more powerful station. It happens all the time to me, as a portable. Lots of hams will still call it a contact. If I get stepped on , I try to come back to the station again. But sometimes-------------. Brad KC9UQR

To those in the northeast, it appears that somebody might be setting up a repeater on the 70cm uplink frequency of AO-92 (at least that's what it sounded like). I got one call sign (from NH), but there is no email address shown on QRZ to inquire about it. Might want to keep this in mind when operating the early passes on AO-92. --Roy K3RLD

Gagarin Cup International DX Contest
by Brennan Price 11 Apr '20

11 Apr '20

There are several ways in which the Yuri Gagarin International DX Contest (CW only) is unique. One of them is that satellite QSOs count. While radiosport on satellites may seem concerning, the level of activity (at least in North America) is usually no more consuming than AMSAT CW Activity Day every New Year's Day, and certainly less consuming than Field Day (or a typical weekend FM pass). I feel it can conducted responsibly, and I am going to try this year. I invite you to join me. I plan to be QRV as time permits in this year's contest, which runs from 2100 UTC Saturday to 2100 UTC Sunday. Recommended CQ format is CQ GC de [call]. Exchange is RST (don't complicate things--599 means no more and no less than "I hear you" in the radiosport context, so send 599) and ITU Zone (8 for me). I will operate via the functional XW-2x satellites, the CAS-4x satellites, and EO-88. I will not try AO-7, as CW is more prone to cause a mode change, all other things being equal. I'll be toward the lower end of the passband when the satellite passes westish or northish from my back deck in FM18iv. I hope to work some of you. I commit to keeping my EIRP low and enjoying the passes with other users. 73 de Brennan N4QX

Re: [amsat-bb] what is a good contact?
by Ev Tupis 11 Apr '20

This issue comes up with regularity. The answer is simple. If you want a direct answer...scroll to the last paragraph of this email. ----- Background ----- Let's play out a scenario from the point of a 3rd party listening to two sides of a valid QSO from the "old days" of voice-based meteor scatter communications: Man's Voice: CQ W2AAA CQ W2AAA CQ W2AAA Break Woman's Voice: W2AAA K0ZZ W2AAA K0ZZ W2AAA K0ZZBreak Man's Voice: K0ZZ W2AAA K0ZZ W2AAA K0ZZ W2AAA Break Woman's Voice: W2AAA S5 W2AAA S5 W2AAA S5 Break Man's Voice: Roger S5 S4 Roger S5 S4 Roger S5 S4 Break Woman's Voice: Roger S4 73 Roger S4 73 Roger S4 73 Break Man's Voice: Roger Roger Roger Break Woman's Voice: Roger Roger Roger Break Man's Voice: Roger Roger Roger Break Woman's Voice: Roger Roger Roger Break Man's Voice: Roger Roger Roger Break Woman's Voice: Roger Roger Roger Break (silence) Unless you were part of the QSO or had engaged in this particular agreed upon protocol before, you would have no way to decipher what just happened. I could explain everything that happened (including the fact that the Man's side of the QSO didn't copy enough to agree that a QSO had occurred during the last exchange and required three repeats until their QSO Protocol was satisfied)... but ultimately, the point is: A QSO is "valid" when two parties agree to a protocol (or follow an events' established protocol) and follow it to their satisfaction. Doing so honorably is part of the hobby. Regards, Ev, W2EV Chairman, Rochester VHF Group The Rochester VHF Group

AMSAT Freq Guide April 2019
by Ron VE8RT 10 Apr '20

10 Apr '20

I rely a lot on the AMSAT frequency guide, to at least double check the software (GPredict). There are several satillites listed on the April 2019 (latest guide I have) that I have no data for, TLE's or transponder. Maybe if I'd been following this list more closely I'd be up to date. They are no longer in service, or would I find them identified as something else? My 475 CAT control worked very well on the latest pass of XW-2B, too bad I couldn't hear anyone else on the west coast. Ron VE8RT -- Ron VE8RT <ve8rt(a)yknwt.ca>

> > I believe > most people use grids because then you are also elligible for all the > awards that go with grid collection. Of course, now that I think about it, if you use LotW or QSL cards, you pretty much get the grid for free no matter what - so honestly maybe grid exchange is popular just because it's quick and straight forward, and works best for people that are listening to ongoing QSOs and need specific grids? --Roy K3RLD

> > Grid squares are required, is there an alternative other than RST? > Ron VE8RT I think all you need to do is exchange ANY type of information (other than your callsign, of course - which IS mandatory). So, grid, first name, occupation, what you had for dinner, etc. I believe most people use grids because then you are also elligible for all the awards that go with grid collection. I also believe that using a recording (that you actually made yourself on the pass) is totally legit. Using a recording from a satnogs station 500 miles away - not so much. I'm not a grid-chaser, per se - so I'm sure somebody else will give you the official position on both questions. --Roy K3RLD

Re: [amsat-bb] suggested audio recorder?
by Russ Kinner 09 Apr '20

09 Apr '20

I use an Olympus IEC JIS LR03 Which is also used to record classroom sessions. Its about the size of a small candy bar and holds about 22 hrs. in mp3 format. It has a built-in USB connector to get the files into a PC and a MIC micro phone jack along built in microphone. Any electronic recorder should work fine with these minimum features. I use Audacity to edit and change formats to get a file that can be emailed or placed on a file service such a Google or dropbox (there are several others if you record daily and need the space.) WD9EWK among several others record most passes on FM birds that are in range. He is only 25 miles away from me so hears the same passes as I do. Look for someone near you if you want to check what other stations hear. With receiver de-sense, you may not hear exactly what others do. There are resources to help on line if you do a little searching. There is no one place to check but Amsat is a good starting point as is this message service. I'm only 2+ months on the FM birds and I have a ways to go to have a good signal/operating practice but I'm much farther along due to on line info. Keep asking questions when you need help. Rusty.

Hello all, I have spend my stay-at-home time hunting... OA4/XQ3SA has been very active on AO7... after 4 days yesterday finally got him, we have a very small window between EM55 and FH17; The old but trusted AO7 came thru for me. Looking at my records that is the longest qso so far I have done via the birds, around 3385 miles. He seem to have some local QRN, but he is there on almost every afternoon pass. 73 Steve W4DTA

Hi,I noted the comments and reports regarding sources of signals being received whilst monitoring AO-7.I am located in Wales ( UK ) and use a simple "ELK " antenna and "Funcube" dongle for monitoringmany of the satellites.I can confirm that recently whilst monitoring I noted strong signals in the band with the software forFox satellites and others during pass times in the morning and late evening.I checked out both MOVE -11 ( Operates 145.950 Mhz ) and MOVE- 11b ( Operates 145.840 Mhz ). The signals were very strong and the Fox Telemetry software in auto late yesterday evening(8th April ) Move-11b on 145.840 and quite wide - It prevented the software from locking onto the Foxsatellite that I was tracking at times.Ken EatonGW1FKY
