request detailed system diagram for remoting a satellite station
by David J. Schmocker 18 Jul '20

18 Jul '20

Hello, Does anyone have a detailed system diagram (or interconnect drawing) showing how they have remoted a satellite station please? Specifically which parts of the system require IP-addressable power on/off, etc. I am in the process of constructing a new satellite station for U/V linear use at Milwaukee Area Technical College (where I teach). Our Data Communication and Networking class introduces satellite technology which I plan to demonstrate live. Because the hours of access to the building are limited, and because we teach Data Communication and Networking from two campuses (but have Satellite station at only one), remoting this station would be desirable. I have an APC IP-addressable power strip (117vac) and some power relays if we need 220vac switched, an IC-9700, two high-power switchable LNAs (2m and 70cm), antennas (20 element RHCP for 2m and 16 Turn G3RUH Helix for 70cm), and a Yaesu 5500 rotor with Green Heron Az/El controller (I'll bring Heliax from home to get to the rooftop). Hopefully our city campus location is not overly noisy. I plan to construct the HEO-ready station as soon as I can be back on campus to do this. One specific area of concern: how to pass audio over internet. I've heard Skype and some other vehicles have problematic latency but I have yet to remote any station to use 'near real-time audio' for CW or SSB QSOs so I lack experience with this. The satellite computer (controlling antennas and managing Doppler) is a Mac mini running MacLoggerDX and MacDoppler software. If helpful, I have two surplus new Raspberry Pi 3s (new and unused) that could be repurposed for part of this if helpful. You'll be happy to know I've been reading the mail and I know to first listen and test so we Tx with minimum power. But as a satellite newby, I'm sure I'll need abundant guidance when we get QRV. Any detailed system diagrams (could be off-list directly to me) showing how you built and configured such a remote station satellite system would be greatly appreciated. Thank you very 73, Dave KJ9I KD9BOG (at work)

In response to the OP <Why are you comparing the legal expenditures with membership fees?> The simple answer is THEY are trying to evoke anger in the electorate, so THEY can take control of AMSAT. Go back and read the intitial allegations in Michelle's and Patrick's "election edition" director reports. See how their lines of attack change each time the true facts are revealed. Their storyline has transformed from illegal expenditures to unwise expenditures. Now go back and read AMSAT's explanation of legal expenses. You will see that there were legitimate legal questions before the Board - question that were not sought by the AMSAT, but, either a necessary part of their mission or forced upon them by their accusers. Having to expend scarce recources on legal counsel is unfortunate, but a necessary part of entering into contractual obligations and providing a safe workplace for your volunteers. Robert, KE4AL

HO-107 is back!

HO-107 is back sending telemetry. The transponder is off, but if you have been copying telemetry and removed it from your schedule, it would be helpful if you put it back. 73, Alan WA4SCA

Most hams want linear transponder, high altitude satellites. Very few are yet into digital anything. Yes, AMSAT should be in the forefront of technology, but to do so, it must be here. To be here, it must have the support (money) of the ham community. We can still make a very good case for emergency commutations with a spacecraft which is in there 24/7 (Rideshare) even if it is only an analog transponder. With moderate bandwidth, that analog transponder can be used for at least low rate digital communication by ground stations. So, still pictures and medical data can be exchanged through it. So, let's get to it. That means fundraising. I have seen very little effort in that direction. Have fat cats been solicited? What about the guy (can't remember his name) who spent $20,000,000 to visit the ISS for a week. It would seem that he is a prime candidate. Has he been contacted? Has FEMA been solicited re the potential Rideshare offers? It's up to the AMSAT leadership to make such solicitations. We raised $2,000,000 here in North America for P3D. We should be able to do it again, despite the AO-40 disaster. These are my thoughts. 73, Bill Tynan, W3XO, LM-10 AMSAT President 1991 - 1998" https://www.amsat.org/pipermail/eagle/2008/001235.html -- Joe Leikhim Leikhim and Associates Communications Consultants Oviedo, Florida JLeikhim(a)Leikhim.com 407-982-0446 WWW.LEIKHIM.COM

Hope Everyone is staying Safe and Healthy.. I hope its ok to change the ongoing thread.. I have heard some New Hams using the Oscar sub bands for FM Simplex. Below Is the ARRL Band Chart Now Reads New 144.30-144.50 New OSCAR subband 145.80-146.00 OSCAR subband They are using Freq 144.315 FM Simplex. One was telling a story over 25 yrs ago they were using this Freq and a complaint was made to the FCC He got a Letter from the FCC . And He called respond the complaint and told the FCC that this was the Old Oscar Sub band that had not been used since the sixties Sats were Not up and working anymore. And the FCC Said do not worry about the complaint. So after listening to all this on 144.315 over a long time I thought the best place to get a real answer would be here. Thanks everyone Please Stay Safe and Healthy 73 At 73 Be careful Old Age is catching LOL Don KA9QJG 2 Meters (144-148 MHz) 144.00-144.05 EME (CW) 144.05-144.10 General CW and weak signals 144.10-144.20 EME and weak-signal SSB 144.200 National calling frequency 144.200-144.275 General SSB operation 144.275-144.300 Propagation beacons 144.30-144.50 New OSCAR subband 144.50-144.60 Linear translator inputs 144.60-144.90 FM repeater inputs 144.90-145.10 Weak signal and FM simplex (145.01,03,05,07,09 are widely used for packet) 145.10-145.20 Linear translator outputs 145.20-145.50 FM repeater outputs 145.50-145.80 Miscellaneous and experimental modes 145.80-146.00 OSCAR subband 146.01-146.37 Repeater inputs 146.40-146.58 Simplex 146.52 National Simplex Calling Frequency 146.61-146.97 Repeater outputs 147.00-147.39 Repeater outputs 147.42-147.57 Simplex 147.60-147.99 Repeater inputs Notes: The frequency 146.40 MHz is used in some areas as a repeater input.

No, this came out of one bank account where your membership dues and donations went, along with any other money the organization happened to make.

Moderation and personal attacks
by Michael Tondee 17 Jul '20

17 Jul '20

I have been informed I'm on moderated status for a "personal attack" so it will be interesting to see if this gets through. I feel I just spoke the known truth but the moderator disagrees so I will play by his rules. At any rate, this bb has been full of "personal attacks" lately both outright and veiled and unfortunately I see it continues with sniping and snide remarks. It's already established that I'm not currently a member of AMSAT and have my reasons why, but I would like to be a member again if I see positive change. You can freely disregard my opinion if you like but I implore all of you to cast your votes wisely and not be influenced by the decidedly personal vendettas of a few here. AMSAT is stagnant and needs fresh direction. Many are like me "on the outside looking in" and very interested to see where you choose to take the future of this organization. Thanks for your time. 73, Michael, W4HIJ

NASA and Open Source
by Bruce Perens 17 Jul '20

I am reading a NASA Grant application today, and noticed this text: Program elements will give preference to proposals that include a plan for committing software as Open Source Software (OSS), beginning at the inception of the proposed work. This plan will include the identification of software components developed as part of the proposed work, and designate a permissive, widely accepted OSS license and a public repository hosting service for these components.
