SatPC32, AO-85, Icom IC-9100
by Clayton Coleman 19 Nov '15

19 Nov '15

This post is specific to Icom IC-9100 users. There have been some ongoing discussions about whether or not to use Narrow FM for uplink or downlink on AO-85. My observation is that Narrow FM (Filter 2) for the downlink works best. For the uplink, I leave Filter 1 enabled. This is easy to do in your DOPPLER.SQF: AO-85,145980,435175,FMN,FM,NOR,0,0,Transponder The first FMN will set Filter 2 for your downlink The second FM will set Filter 1 for your uplink. I've also noticed Filter 3 makes LilacSat-2 sound best but I am unaware of a command via SatPC32 to select that filter automatically. 73 Clayton W5PFG

ULA to provide free cubesat launches for universities

Hi all, Not sure if this is recently known but ULA is now offering free launches for cubesats made by universities. Should bring an interesting round of competition between the schools. http://www.ulalaunch.com/ula-reveals-transformational-cubesat-launch.aspx?t… 73, Jeff WB3JFS

ANS 321 AMSAT NEWS SERVICE SPECIAL BULLETIN - AO-85 Commissioned, Handed Over To AMSAT-NA Operations
by E.Mike McCardel 19 Nov '15

19 Nov '15

AMSAT NEWS SERVICE SPECIAL BULLETIN ANS-321 The AMSAT News Service bulletins are a free, weekly news and infor- mation service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor at amsat.org. In this edition: * AO-85 Commissioned, Handed Over To AMSAT-NA Operations SB SAT @ AMSAT $ANS-321.01 ANS-321 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 321.01 >From AMSAT HQ KENSINGTON, MD. November 17, 2015 To All RADIO AMATEURS BID: $ANS-321.01 AO-85 Commissioned, Handed Over To AMSAT-NA Operations AO-85 has been formally commissioned and turned over to AMSAT Operations, who are now responsible for the scheduling and modes. The following guidelines are provided for users: Uplink power should be on the order of minimum 200 W EIRP for full quieting at lower antenna elevation angles. Your mileage may vary. With an Arrow, 5 W has been used successfully to make contacts. Polarity is important. The satellite antennas are linear. So, if you are using linearly polarized antennas, you will need to adjust throughout the pass. Full duplex operation facilitates these adjustments while transmitting and is highly recommended. The downlink is very strong and should be heard well with almost any antenna. Downlink audio is 5 kHz deviation, as expected. Many will perceive that the audio is "low." This is an effect of the filtering below 300 Hz, which provides for the DUV telemetry, coupled with any noise on the uplink signal resulting from lack of full quieting or being off frequency. That makes for less fidelity than a typical receiver in terms of audio frequencies passed. Transmit (downlink) frequency varies with temperature. Due to the wide range of temperatures we are seeing in the eclipse cycle, the transmitter can be anywhere from around 500 Hz low at 10°C to near 2 kHz low at 40°C. Receive frequency has been generally agreed to be about 435.170 MHz, although the AFC makes that hard to pin down and also helps with the uplinks that are off frequency. Probably the most notable observations about AO-85 are an apparent lack of sensitivity and difficulty in turning on the repeater with the 67 Hz CTCSS when it is not yet activated, or holding it on by the presence of the CTCSS. We have determined a probable cause for the sensitivity issue and while that can't be fixed on AO-85 we are taking steps to prevent similar issues on the rest of the Fox-1 CubeSats. The tone detection threshold along with the receive sensitivity issue makes it hard to bring up the repeater. This is being addressed by adjusting the values for a valid tone detection in the other Fox-1 CubeSats now that we have on orbit information about temperatures and power budget. Full details will be in the Nov/Dec AMSAT Journal. It is important to remember that science is the reason behind the Fox-1 satellites. Not only does science help with the launch cost, it provides a great amount of educational value both from the science payload and in amateur radio itself. The data-under-voice (DUV) telemetry is an excellent way to provide the science without sacrificing the use of the satellite for communications, which would be the case if higher speed downlinks were needed. DUV provides constant science as long as the repeater is in use, which in turn provides more downlink data for the science - a mutually beneficial combination. Fox-1A is AMSAT-NA's first CubeSat. Many new techniques are incorporated and lessons will be learned, as with any new "product." The Fox-1 Project is a series of CubeSats. A total of five will be built and flown. Launches are scheduled for three more, and a new NASA CubeSat Launch Initiative proposal will be submitted for the fifth. We will incorporate changes from what we learn in each launch, to the extent possible, in subsequent Fox-1 CubeSats. Of the four NASA sponsored CubeSats on the ELaNa XII launch October 8, we are sad to report that ARC1 was never heard from and BisonSat was lost after a few weeks of operation. AMSAT extends our deepest sympathy to the people who worked so hard on these projects. To our members, we want to say that the Fox Team is very proud and pleased that our first CubeSat is very successful and hopefully will be for some time.

If you have just one choice, what is the best polarization to receive LEO Birds?
by Vinicius Leite 18 Nov '15

18 Nov '15

Hi Folks! I'm novice and sorry if this is a dumb question. I have a regular 7 Element Yagi UHF antenna, and i would like to know what is the best position to receive LEO birds: horizontal, vertical or 45 degrees to the right? I've googled this, but i found a lot of different opinions. On the field, if somebody tested this options, can please share the results with me? Thanks a lot! 73s! -- *Vinícius Leite* PU4VLT / PY4218SWL Grid Locator.: GH70XD pu4vlt(a)gmail.com Cel.: (31) 9 8422-0424
