Re: rotor replacement pots

A digital encoder would be the most accurate. USdigital http://www.usdigital.com/support/glossary#glossary_opticalencoder manufactures inexpensive encoders. With these and a step servo drive in example a Gecko drive http://www.geckodrive.com/product.aspx?c=2&i=14456 one could build a rotor that would be accurate to a thousand of a degree. Fred KF0AK

way of satellite recovery?
by AB2VY 19 Nov '08

19 Nov '08

Hi to everybody, after have reading this article about the possibility of bringing Vanguard 1 back to Earth http://www.msnbc.msn.com/id/23639980/ , an "unhealthy" idea has crossed my brain... , premise that Vanguard 1 is "3.25-pound (1.5-kilogram), 6.4-inch-wide (16.3-centimeter-wide)" so little.. , a program to recover/repair something of too bigger ( like... AO40 ?? ......) is possible ? if the answer is "yes" the costs are too bigger or too low than the launch costs (4.5 million to 15 million Euros to launch) explained by David G0MRF in the past message? Logically it is necessary that NASA has a similar mission to which rely... would be an interesting study on this possibility of recovery/repair a satellite like AO40 "dead" in space this message wants to be an open track for a discussion about "Satellite repair in Space" thanks for your attention and best 73 Giulio AB2VY (ex KC2OTB) c/o Toms River NJ AMSAT-NA member 36417 Posta, news, sport, oroscopo: tutto in una sola pagina.

AO-51 L/U SSB mode
by Luc Leblanc 08 Oct '08

08 Oct '08

Hi Something happen at 2300Z (1900EST) suddenly the audio level jump louder by a factor of 4 i have to reduce my volume level and i found my TX audio was also much too loud... Now AO-51 look like AO-16 audio and QSO are manageable. I succeed to have one with Clare VE2NPC and i also copy a lot of station but at the same floor level strength i used to have before my adjustment (see below). Only Clare VE3NPC signal seems to get over this curious bottom floor level?? To be clearer all the station coming out the satellite are equal in strength? Only Clare was louder as a kind of AGC treshold seems to be set too high making a kind of squelching effect? I just made some adjustment here at the end of the afternoon in a hurry and from an uplink signal very marginal it became near Q5!!! i'm not too sure what i done and if it is what i done who boost my uplink but i will have to make some test again as said something happen also on the satellite at the same time? More to come...and i was able to hear my downlink at LOS + 3'!!! "-" Luc Leblanc VE2DWE Skype VE2DWE www.qsl.net/ve2dwe WAC BASIC CW PHONE SATELLITE

Advertising Shuttle Retransmission Faclities on APRS
by Robert Bruninga 01 Oct '08

01 Oct '08

To Shuttle rebroadcasters: Many people do not monitor your Shuttle Retransmission frequencey all the time, and so, may not remember that the Shuttle is in orbit. Therefore, a TNC should be connected to the Retransmitter that activates an APRS beacon on the local APRS channel whenever it is keyed. This APRS beacon will alert all mobiles on the front panel of their APRS radios in range that the retransmission is in progress. We need to get this info out to all volunteer rebroadcasters... This web page shows how to use just an old TNC and no special software to format the beacon so that it shows all the relevant information right there on the front panel of the mobile APRS radios: http://www.aprs.org/On-Air-beacons.html This technique also applies to all re-broadcasters of the Newsline, RAIN report, ARRL Audio file, and any other general info nets that need to be heard by all radio amateurs. APRS is your universal real-time ham radio information channel. If you have info to share, beacon it on APRS live. Monitor APRS and see what is happening in your area. Bob, WB4APR

Telemetry
by Tim Tapio 29 Sep '08

29 Sep '08

Hello all! Two questions on telemetry.. 1. I was considering dedicating a 70 cm "eggbeater" with a preamp as a good, omni-directional antenna. So far though, it doesn't seem to pick up below 12 degree elevations. Currently the preamp is in the shack (I know, at the antenna) and my coax is not optimum. If I use heliax, put the preamp at the antenna, is this feasible or should I plan on a steerable beam? 2. I'm having a dickens of a time figuring out what the telemetry frequencies are. I've looked at DK3WN's site which has the decoding software but I seem to be having issues finding frequencies, am I looking in the wrong places? Thanks for your time! 73 de Tim, K4SHF FM04

AO-51 L/U very cool!
by DeYoung James 29 Sep '08

29 Sep '08

Greetings, I finally decided to try L/U on AO-51 using my IC-910H, SATPC32, 70-cm arrow on a camera tripod, and a 10-elem. "cheap yagi" for the 1.267-GHz uplink. Very good signals for all on the downlink most of the pass, however my uplink on 1.267-GHz is heavily affected by trees, the fact I operate from inside my home from the 2nd floor, and I was arm-stronging the cheap yagi whilst twisting for polarization!. Great to hear Angelo, Carmen, Clare, and Mike. Thanks for calling me back in the group. A very cool mode that works very well. 73, JIm (N8OQ ex KG4QWC)

Re: AMSAT-BB Digest, Vol 3, Issue 491
by Gopal Madhavan 28 Sep '08

One suggestion I had posted some time ago for these rotors was to change the bolts holding both halves together when the rotor is NEW and before it is put up in use, to Allen head bolts. The standard bolts with flat screwdriver heads become almost impossible to remove once the ravages of weather have had their toll. The Allen head bolts can be moved easily as the wrenches do not slip or damage the slots Also if the end stop limit switches fail, the rotor drives the unit past the stops ( which are just bent tabs on the mounting plate) and bends the whole thing out of shape. I have had this happen twice.

Two questions on telemetry.. 1. I was considering dedicating a 70 cm "eggbeater" with a preamp as a good, omni-directional antenna. So far though, it doesn't seem to pick up below 12 degree elevations. Currently the preamp is in the shack (I know, at the antenna) and my coax is not optimum. If I use heliax, put the preamp at the antenna, is this feasible or should I plan on a steerable beam? 2. I'm having a dickens of a time figuring out what the telemetry frequencies are. I've looked at DK3WN's site which has the decoding software but I seem to be having issues finding frequencies, am I looking in the wrong places? Thanks for your time! 73 de Tim, K4SHF FM04 ------------------------------ Message: 5 Date: Sun, 28 Sep 2008 12:49:19 +0000 From: Nigel Gunn G8IFF/W8IFF <nigel(a)ngunn.net> Subject: [amsat-bb] Re: Chinese bird To: nigel(a)ngunn.net Cc: AMSAT-BB <AMSAT-BB(a)amsat.org> Message-ID: <48DF7D4F.5030805(a)ngunn.net> Content-Type: text/plain; charset=ISO-8859-1; format=flowed I will summise that: Object B was the original crew/payload module. Object B then split into 3 induvidual parts to become Object F, the re-entry module and Objects B and E are the propulsion module and crew module. Object G is the satellite they ejected. Objects A, C abd D are the rocket body and shields.

who was that masked man?
by Greg D. 28 Sep '08

28 Sep '08

Right at the end of this morning's FO-29 pass (about 17:50z) I heard a station that sounded like "AL1S" in grid square AP90. That grid would be in Alaska, which was in the footprint, but there's no AL1S up there (nor KL1S, for that matter) according to QRZ.com. Anybody know who that was? I was at about 5 degrees elevation on the satellite, and I think he caught my call sign correctly. I was just about to confirm it all, then my south-centered antenna controller decided it was time to swing around to the other side of zero azimuth. By the time the antenna came back around a minute later, he was gone. Related side-question: Does anyone know if the latest version of Predict (Linux version) supports "flipped" antenna rotor operation? My rotor and controller can do it, but Predict 2.2.1 doesn't.
