LA4FPA/p JP32BM
by John Papay 23 Jul '10

23 Jul '10

Erling, LA4FPA/p, is on Vigra Island, JP32BM for a holiday. He will be on the 2014 UTC pass of AO-7 today, 23 July. AO-7 is in Mode B and this is an excellent pass for the Northeastern/Northern USA and Canada. Here's a great chance to add Norway to your list of countries. Keep it short so everyone has a chance to work him. 73, John K8YSE

AMSAT-NA members, The biographies and ballot for the 4 candidates for the AMSAT Board of Directors went out on July 15th. In order to be counted, your ballot must be RECEIVED at the AMSAT office by the close of business on September 15th. Now is a good time to review the biographical information, ask questions, and study the minutes of the recent Board of Directors meetings from the AMSAT Journal. Finally, please vote. This, along with the yearly opportunity to stand for election, is your best opportunity to influence the direction of our organization. 73, Alan Biddle WA4SCA AMSAT-NA Corporate Secretary

Re: AO-51 S band Question
by Andrew Glasbrenner 22 Jul '10

Reid Crowe wrote: > > Drew, > Do you think the bird will be able to support 2.4gig in the future? > -Reid > Hi Reid, I hope you don't mind if I copy this answer to the -bb as well. It's a good question. The batteries on AO-51 have lost significant capacity since launch six years ago, and in order to protect and lengthen their life as long as possible, we are limiting the load during eclipse by shutting off the UHF transmitter. We are also using the PL to only turn on the UHF transmitter when in use. Both of these actions are controlled by the flight software, specifically the PL and power management routines. Since the S band transmitter on AO-51 is an added "experiment", the ways in which it reacts with the IHU and flight software are different than the UHF transmitters. The PL cannot be used to turn S on or off, only to gate the audio. The power management software is unable to control the state of the S band transmitter as well. The S transmitter is a fixed output, that draws about 730 mA. This is an equivalent load to running the 435.300 transmitter at over 1 watt. In other words, it is not an insignificant load. Since the return of eclipses this summer, after a long period of total illumination, we have discovered that the S transmitter will pull the battery voltage too low during eclipses. This activates a software watchdog that shuts the S transmitter off until commanded back on from the ground. As a work around, we have been using the automatic mode scheduling software to re-enable the S transmitter a few minutes after exiting eclipse each orbit. This has worked very well. The downside is the scheduler only holds 18 events, as it was designed for the weekly mode changes. At 1440 minutes per day, and 100 minutes per orbit, you can see we need to upload a new schedule every day to keep S running every orbit. As long as the satellite is in the sun, there is no problem running the S downlink. So, you can see why we have been frugal with S activity this summer, as it is a real load on the command stations to plan the daily schedule, encode it, and upload it to the satellite daily (at 5AM). The good news is we return to a no eclipse period at the end of August, and I plan to run S at a ~minimum~ of 1 week a month until eclipses return in 2011 for many years. This works out OK over the summer, as there are lots of folks on right now from their vacation spots, and out on the roads giving out rare grids. I hope this long-winded, probably-too-detailed explanation answers your question. 73, Drew KO4MA BTW, this AM Mark N8MH raised the 435.300 output to 1 watt.

AO-51 from DM04 Thursday Night
by Clint Bradford 22 Jul '10

22 Jul '10

I will be demo'ing AO-51 from DM04 for the Antelope Valley Amateur Radio Club this evening during the 6:23PM PDT pass. Hope to meet a couple of you there tonight! Clint, K6LCS P.S. - Regarding the Wouxon HT YouTube video that was cited earlier - Did you count the number of RF adapters on the HT to connect to the antenna? I think there are SIX!

Lake Superior Grid Expedition August 2010
by John Papay 22 Jul '10

22 Jul '10

My 3 or 4 week grid expedition around Lake Superior is about to start. The planned date is August 2nd, however, a jury duty summons may interfere with the departure date. Hopefully we will leave on time or a few days late. The grids planned are: EN28-29-36-37-38-39- 46-47-48-49-56-57-58-59-63-64-65-66-67-68-69-73-74-75-76- 77-78-79-83-84-86-87 and EO30 in both the US and Canada. There will be FM and SSB activity, probably little CW if any. This is a sightseeing trip around Lake Superior but I will do my best to operate on the birds as much as possible. We will be camping in a tent most of the time. Moving most every day will make it interesting. My XYL, W8ZJB, will be on the air only to work me if I have remote access on the internet or cellphone. She agreed to do this but please don't call her for a contact. She won't likely respond except maybe to our son, KD8CAO. Doug will be the point of contact for anyone wishing to get a message to me during the trip. I don't anticipate much cellphone coverage while we are in Canada. The planned route is on my website: http://www.papays.com/sat If you have specific requests, please email them to me and I'll make a list and will be sure to look for you when I am in the grids you need. The station is a TS2000, dual band Alinco for SO-50 and AO-27 receive only, G5400b, LVB tracker, SatPC32, Arrow 7x7 UHF with relay switching between horizontal and vertical and a 5 el Mosley, vertically polarized for 2 meters. I have a Mirage UHF preamp to help cut down on the coax loses. All of this is in a F150 pickup. Other than orienting the antennas north, everything is computer controlled and operating in the rain is not a problem. Backup is my Kenwood V7A mobile with a neck strap, a 7ah UPS battery, the Arrow II antenna, digital voice recorder etc. We may do a backpack to Isle Royale with this setup if time permits. As always, I plan to qsl everyone I work on this trip. If you do send an SASE, please wait until the end of the trip and include all of your qso's on a card or sheet of paper. I anticipate that all passes will be recorded. I look forward to giving out a lot of needed grids. Hopefully the equipment will work well throughout the trip. 73, John K8YSE

ISS
by Jack Barbera 22 Jul '10

22 Jul '10

Just noted that the listing for ISS in satellite details @ AMSAT has the uplink 145.800 and down 437.800 ,but Satpac has just the reverse for the voice repeater. Which is correct? thanks for any help Jack WA1ZDV
