by Clayton Coleman W5PFG 03 Jun '18

03 Jun '18

It's time to submit nominations for the upcoming AMSAT-NA Board of Directors election. Three directors' terms expire this year: Tom Clark, K3IO, Mark Hammond, N8MH, and Bruce Paige, KK5DO. In addition, up to two Alternates may be elected for one-year terms. A valid nomination requires either one Member Society or five current individual members in good standing to nominate an AMSAT-NA member for Director. Written nominations, consisting of the nominee's name and call, and the nominating individual's names, calls and individual signatures should be mailed to: AMSAT-NA, 10605 Concord St, #304 Kensington, MD 20895-2526. In addition to traditional submissions of written nominations, which is the preferred method, the intent to nominate someone may be made by electronic means. These include e-mail, fax, or electronic image of a petition. Electronic petitions should be sent to martha(a)amsat.org or faxed to (301)822-4371. No matter what means is used, petitions MUST arrive no later than June 15th at the AMSAT-NA office. If the nomination is a traditional written nomination, no other action is required.

Generally this question is asked WRT calibrating a rotor to north. In these cases the antennas on the rotors will be higher gain with a more narrow beam width. One must know all the variables like beam width and deviation at the QTH to say whether it is important or not. 73, Mike Diehl W8LID > On Jun 3, 2018, at 14:48, John KI4RO <johnki4ro(a)gmail.com> wrote: > > That's my point...for the average guy using a standard ARROW it isn't that big a deal....just get it pointed N or S and away you go. hi hi > > > 73 > John KI4RO > > >> On Sun, Jun 3, 2018 at 2:41 PM, Mike Diehl <diehl.mike.a(a)gmail.com> wrote: >> You bring up an important point regarding beam width.

Wisp & Settings
by Vincenzo Mone 03 Jun '18

03 Jun '18

Hello, I am trying to set the Wisp on Windows 10 but having problems to get the settings permanent. If I go into Tracking and select the satellites I want to have under eyes, When I close the GSC and shut down the PC on the next Start-up of the PC and the Wisp program, I get the lower part of the GSC program Empty. I have to go again in the tracking tab and select again the satellites but At the next shut down and restart I am again at the beginning point. What to do to get them permanent?

DATE JUNE 03, 2018 To All RADIO AMATEURS BID: $ANS-154.01 Help Requested to Monitor for Signals From Chinese Lunar Sats After their launch on 2018-05-20 at 21:28 UTC, LJ 1 and LJ 2 were maneuvered onto a track to the Moon. Several amateurs received telemetry from the satellites. But now LJ 1 appears to encounter problems. Quoting Wei BG2BHC: "Can you help to find amateurs in the US to help to monitor DSLWP-A on 435.425 and 436.425 now? We lost the contact of satellite A on S band after an orbit adjustment. We just tried to switch on UHF, but we don't know if it works or not. If operating, 435.425 MHz should be 500bps GMSK and JT4 alternately. 436.425 MHz should be 250 bps GMSK. Both transmit once in 5 minutes.

On May 31 http://www.spaceweather.com issued this Solar Wind Alert: "NOAA forecasters estimate a 60% chance of minor G1-class geomagnetic storms on June 1st, increasing to 65% on June 2nd, when a stream of high-speed solar wind is expected to reach Earth. The last time this gaseous stream lashed our planet's magnetic field, almost a month ago, it sparked bright ribbons of purple light (a.k.a. 'STEVE') seen from multiple US states. Visit today's edition of http://www.spaceweather.com for more information." The Sun remained active over the past reporting week. Average daily solar flux rose from 70.1 to 74.9, and average daily sunspot number rose from 7.7 to 26.3. During the previous week in which the average daily sunspot number was 7.7, the first four days had no sunspots. New sunspot regions appeared on May 21, 23 and 24. Predicted solar flux is 77 on June 1-3, 76, 74 and 72 on June 4-6, 70 on June 7-8, 71 on June 9, 72 on June 10-14, 70 on June 15-17, 72 on June 18-23, 73 on June 24, 72 on June 25-30, 70 on July 1-6, 72 on July 7-11, 70 on July 12-14 and 72 on July 15. Predicted planetary A index is 25 on June 1-2, 15, 12 and 8 on June 3-5, 5 on June 6-12, 8 on June 13, 5 on June 14-18, 8 on June 19, 5 on June 20-23, 8 on June 24-25, 5 on June 26-27, then 15, 28, 15, 12, 10 and 8 on June 28 through July 3, then 5 on July 4-9, 8 on July 10, and 5 on July 11-15. 2018 ARRL Field Day is June 23-24. Assuming the predicted numbers above, conditions should be good for Field Day. We want to see low geomagnetic activity, and planetary A index at 5 and 8 on Saturday and Sunday are good indicators. During this period of low solar activity solar flux at 72 and 73 is also good. Ted Leaf, K6HI of Kona, Hawaii reports that he is still in operation through the local volcanic activity, and asks, "Are there beacons for the lower frequencies, especially now with the lower solar flux?" I found this Wikipedia resource for HF beacons: https://en.wikipedia.org/wiki/Amateur_radio_propagation_beacon Of course, there are lower frequency HF resources on http://www.wsprnet.org, but this is a bit different than showing what you can tune in and hear without using a special weak signal mode. Any readers have suggestions for lower frequency HF beacons? Note that Ted has a comment on page 56 of the June 2018 QST regarding preamps and attenuator effects on receiver noise. >From last week: https://bit.ly/2LG8MAp F.K. Janda, OK1HH brings us this geomagnetic activity forecast for the period June 1-26, 2018. "Geomagnetic field will be: Quiet on June 11-12, 16-17, 20-23 Quiet to unsettled on June 10, 18, 24-25 Quiet to active on June 8-9 Unsettled to active on June 3-4, 7, 13-15, 19 Active to disturbed on June 1-2, (5-7, 26) "Solar wind will intensify on June 1-3, (4-8, 13-15), 16-17, (18-19, 22-24) "Remark: - Parenthesis means lower probability of activity enhancement. - Forecasts remain less reliable." >From Dr. Tamitha Skov, the Space Weather Woman: "What's Old is New Again "Dear Tad, "I am still smiling at the huge response I got to a post I put up on Twitter this week. A newbie to our Space Weather community dared to talk about amateur radio as if it were an outdated hobby-- whoops, bad idea. I gently educated him. In doing so, I roused many radio amateurs and emergency communicators, who added their own comments and talked about their own personal experiences in the field. It was very gratifying. What I hadn't expected, however, was the strong interest in the concept that amateur radio will be critical to establishing over-the-horizon radio communications on planets like Mars in the near future. "This idea brings me back to how we managed to communicate over long distances many decades before we had satellites, internet or cellular networks. In terms of wireless communications on Earth, we were very much in the same place back in the early 1900s that we find ourselves in now when we think about colonizing Mars. Yet few people realize that despite all our advanced technology, we can't bring a cell phone to Mars. We will need to fall back on our 'old ways' of doing things when it comes to communicating on other planets. Isn't it funny how 'old' things become 'new' again? "Speaking of, this week brings us a new chance for a decent solar storm. Strangely though, the source of this storm is an old coronal hole that gave us a moderate level solar storm about a month ago. This old hole has survived its backside passage on the Sun and has now returned, with the new promise of bringing aurora views down to mid-latitudes again. Isn't it funny, what was old has become new again, in more ways than one!

True bearings vs. magnetic
by Rick 03 Jun '18

03 Jun '18

I recently saw a question about this, but missed the answer. Being a newbie to sats also, I was wondering about that too. I assume it’s true bearings, because if it were magnetic, that would entail everyone to calculate the declination from there locale. So is it true? Thanks! Rick KE6LL

Easy Rotor Controller (ERC-M), SATPC32, and Yaesu G5400B Antenna Rotor
by Roger Heindl 03 Jun '18

03 Jun '18

The Milwaukee Radio Amateur Club is sponsoring and assembling an ARISS contact station. We've purchased an ERC-M USB from Vibroplex and installed SATPC32 on a Windows 7 laptop. Our initial tests with the included software for the ERC work and we can control the rotor when we specify COM4. However when we launch SATPC32, the Rotor options for Yaesu only list LPT ports. Could anyone provide guidance for a way to specify USB COM4 for the ERC in the SATPC32 software? Reading the archives, it seems like others have been successful with this configuration. Could someone provide us with additional information on your setup for SATPC32? Or should we possibly consider an alternate software such as GPredict (though GPredict only had network settings for rotor control, I didn't see any COM port fields in GPredict either). I'm a bit confused how others set this up. Thanks for any assistance, Roger AC9BT

Beginner Resources
by Brad Brooks 02 Jun '18

Butch, satellite operation can be daunting. There is a TON of information out there however. Let me suggest a couple of resources: Start here --> https://www.amsat.org/station-and-operating-hints/ Also, look into getting this book --> https://www.amsat.org/product/2018-edition-of-getting-started-with-amateur-… You didn't say what aspect of Sat operation you are interested in, or the scope of the middle school ground station, but there is plenty of good starter info above. As to the quality of information on this EMAIL reflector, it is what it is. This is NOT a threaded BBS, it is an email service. As to the storehouse of info, you can peruse the amsat-bb archives which I find quite helpful. There is quite a lot of info on Social Media as well. My suggestion is to review the link above, and ask your questions here and your social media of choice in order to further your knowledge. 73 Brad WF7T Nashville, TN EM66 --- Message: 11 Date: Sat, 2 Jun 2018 11:31:31 -0400 From: Butch <occamrazr(a)yahoo.com> To: AMSAT-BB(a)amsat.org Subject: [amsat-bb] My two cents on this BBS vs. " A forum" Message-ID: <38E62D65-A5EF-4D7E-BA9C-453F08B85CD2(a)yahoo.com> Content-Type: text/plain; charset=utf-8 I am an old ham but new to satellite operations and I?m building a ground station for a local middle school. I fully support AMSAT and this BBS. I have been on this BBS for a few months now looking for information that I could use. I?ve gotten good responses to my specific questions, but as a resource for newbies, I find it lacking. This BBS seems to me more of a ?chat line? than a store house of knowledge. I would like to suggest that AMSAT create a forum that keeps up to date info on specific subjects such as active satellites, specific satellites (and their quirks), basic info for newbies, product reviews, volunteer Elmers, homebrew projects, buy/sell/trade, etc. In this way, the accumulated knowledge is stored and searchable and not tossed into the recycle bin. I would also like to suggest that AMSAT survey its members to get some real data on their thoughts rather than just having an open ended discussion. Thanks for listening. Butch K8KO
