AMSAT: RFI from LED bulbs?

by Robert Bruninga

I am hearing reports of RFI from these LED bulbs. Not just HF, but also VHF. If you can make any quantitative assessments of such RFI, please let me know. And the amazing thing is that at VHF you will never notice it because RFI is noise power and it is noise power that keeps a squelch CLOSED. Manuallly open the squelch and sometimes RFI will show full scale on the S meter yet not open the squelch. And on my radios, when the squelch is closed, the S meter is inactive and shows 0.

TLEdoctor program to check for preliminary TLE data

by Jarda

The program can easily detect and fix the TLE preliminary data errors for working in satellite programs after launching the satellite in orbit The original version of the program released before launching Fox-1D works in Windows-7 and higher. Version that works in Windows XP is now added. The program name for Win-XP changes to TLEdoctor. Both programs can be downloaded at http://oscar.ok2gz.eu/fox1d.php 73 Jarda ok2gz --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Transponders For Rent???

by Brad Smith

Yes, I would rent in a minute. This would be my solution for working the sats. in the Wisconsin Winter! Brad Smith KC9UQR <So, like "FM Tower for Rent", signs as seen all over the U.S., could we soon see "GEO TV Satellite transponder for rent" as well ?Maybe this could be an answer to a ham GEO transponder ?>

AMSAT'S Cost for Launching the SATS

by Gerald Witalec

Just curious. It seems as though it is getting difficult about placing he ham SATS dueto cost. I wonder what may happen if the cost is so prohibitive that AMSAT could possibly go by the way side. Just asking. Jerry

Re: [amsat-bb] AMSAT-BB Digest, Vol 14, Issue 292 (HEO's, AMSAT perception)

by Michael

Just from the outside looking in... AMSAT APPEARS only to be interested in hoisting flying repeaters and PACSAT/APRS and showing the average ham how "easy" it is to work sats with a handheld and a simple antenna. I guess that's all well and good but I didn't get in the sat end of the hobby for "easy". I wanted a new challenge. I was too late for A0-40 because of lack of funds for a station but I did have fun for awhile chasing AO-51, FO-29, AO-7 etc. with a TS-2000X and a homebrew rotator and antenna system. Unfortunately, life got in the way and I needed family funds so the Kenwood hit Ebay and I'm inactive on the birds now. I sometimes consider buying a couple of Baofengs (you should ALWAYS operate full duplex but that's another thread) and getting back in on the cheap, I even recently bought a beat up old telescope with a computer tracking tripod system I spotted at Goodwill, but honestly, the challenge isn't there to give me motivation. Before everyone flames me, as I said, this is from the outside looking in and just one man's opinion. I really wish AMSAT would do something, anything, to change my perception. Seems to me I saw something about a YL running for the board who's interested in open sourcing stuff. Her candidate statement was IMHO, a much needed breath of fresh air but I'm no longer a member and don't keep up so no idea if she got elected. If AMSAT wants my membership and donation dollars back, they need to change perception and I suspect there are many out here in the community who feel the way I do. 73, Michael, W4HIJ >> Somewhere in AMSAT there is someone who has "Project Managed" long enough >> (or has access to process-flow diagrams) and can publish a generic work >> breakdown of both the steps and resources needed to put a highly elliptical >> (presumably less expensive) or Geostationary (presumably more expensive) >> bird into orbit and manage it. >> >> If that person (or people) could publish that along with a "checkmark" >> next to the items that are "already in place", "in active progress", and >> "needs sponsor/enthusiast" then we are more likely to fill-in the gaps. >> >> Remember the "Six Degrees of Kevin Bacon" game (a.k.a.

AMSAT-NA

by Ray Soifer

I am not a candidate for the AMSAT BoD (been there, done that) nor am I endorsing or opposing anyone. Most of you know me; if not, please see my QRZ.com page. As the the then EVP, it was my fate to be Acting President during the failure and partial recovery of AO-40. AMSAT's basic problem is financial. Universities and even high schools get NASA up.money to build and launch Cubesats, while AMSAT's limited resources are slowly drying up. I don't have a solution, but I am not running for the BoD. I urge those who are to put their solutions forward, not just their gripes. 73 Ray W2RS

HEO/Elliptical [was: AMSAT-NA solution: DX (HEO) to attract more interest and revenue]

by Nicholas Mahr KE8AKW

I know we currently have AMSAT-DL's P3E sitting in storage in Germany. Perhaps some day we can find a good opportunity under the government to fly P3E with a bunch of experiments for them like what AMSAT found under the Virginia Tech P3E opportunity in 2015 which dident happen because they wanted us to pay 4M to insure on time integration. I do think advocating that it can be used for emergency communications and for flying their experiments could definitely help us find a rare opportunity in that Molniya type orbit. I assume that the de-orbiting could possibly be done with its Kicker Motor? Ultimately, we are under the mercy of the launch providers and government regulations. I do think that with hard work from our wonderful AMSAT volunteers, we can get back to HEO/GEO at soon. Also the work on Phase 4 ground has been wonderful. I wish the best fpr Phase 4 project and the GOLF program. 73, Nick KE8AKW
