Fw: AO73 Mode change
by Graham Shirville 11 Jun '19

11 Jun '19

Hi folks, AO73/FUNcube is now in amateur mode for the weekend with the transponder on! Please see below for all FUNcube mission info 73s Graham G3VZV and the FUNcube team. ++++++++++++++++++++++++++++++++++ FUNcube frequencies and other details ++++++++++++++++++++++++++++++++++ AO-73 FUNcube-1 The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 - 435.130 MHz LSB (Inverting) Downlink: 145.950 - 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15kHz higher depending on on-board temps. Lower temperatures give higher freqs!) FUNcube-2 (aka FUNcube on UKube) The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 - 435.060 MHz LSB (Inverting) Downlink: 145.930 - 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regula… EO88/Nayif-1/FUNcube-5 EO88 is presently operating in autonomous mode. The transponder is operational when the satellite is in eclipse, ie the solar panels are NOT being illuminated. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. The transponder frequencies are: Uplink: 435.045 – 435.015 MHz LSB (inverting) Downlink: 145.960-145.990 MHz USB Telemetry Tx: 145.940MHz All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL.

Satellite Basics (Part 2) article by KX9X
by Ryan Noguchi 11 Jun '19

11 Jun '19

Sean KX9X posted another introductory article on satellite operating on https://www.onallbands.com/satellite-basics-part-2-making-qsos-via-satellit…. Check it out. I did have a few exceptions to the advice given, as I believe they suggest less-than-ideal operating practices. Rather than contact Sean directly, I figured it would be worthwhile to post them here. If they're controversial, perhaps it will stimulate some thoughtful discussion. I want to start off by saying that I applaud Sean for providing some very thoughtful contributions to help introduce potential new satellite ops to the birds. My intent is really to provide constructive suggestions for improvement of the advice that we as a community provide to new satellite operators to set them off on the right path. "Currently, all FM satellites in orbit require a CTCSS (PL) tone of 67.0 Hz on your transmit frequency." Mostly true, but LilacSat-2 and PO-101 don't follow this model. "These instructions assume you are using a hand-held directional antenna. If you’re using your standard dual-band vertical antenna at home or on the roof of your car, you can ignore those instructions." Oh, man, I really don't think we should be encouraging newbies to try to work satellites using a vertical to receive the downlink. Also, very unsure why vertical antenna ops should ignore any of the rest of the instructions... Maybe okay to use a vertical to transmit, but to receive they really ought to be using an antenna with gain or with the ability to rotate to match polarization, ideally both. Please, let's not encourage more alligators! "A suggested frequency list of the three active FM satellites at the time of this writing (May 2019) is in Figure 1." Rather than provide yet another frequency list, can't we just reference an authoritative source elsewhere, e.g., on the AMSAT-NA web site? We all remember that recent ARRL article that posted many wrong frequencies; let's try to avoid risking a relapse of that. A frequency list like this can be helpful, so perhaps AMSAT-NA could include a list like this on the Frequency Summary page? FM Satellite Frequency Summary – AMSAT | | | | FM Satellite Frequency Summary – AMSAT | | | "Listen for a QSO to end, then give your callsign and your grid square, using standard phonetics." I don't think we should be suggesting that ops drop their call and grid on a busy FM pass. Unless you've already worked everyone else on the pass, there's really no good reason to just drop your call and grid. Find someone who is solid into the bird and appears to be hearing other stations well, and call them directly. (But not immediately after they've called someone else!) If you've already heard a callsign a couple of times during the pass, it'll also be easier to repeat it on the first try. When you wait until someone calls you, you run the risk of not being able to catch their full call on the first try and needing a fill. I think having the new op initiate the QSO gives them the best chance of having a successful first QSO. "KX9X: “Whiskey One Alpha Whiskey, thanks, Echo November Five Zero, Illinois, QSL? W1AW: “QSL, Fox November Three One, Connecticut, QSL?”" Much of this back-and-forth is extraneous. KX9X already provided his grid in his first transmission, and W1AW already provided his grid in his first transmission. Neither asked for a fill. Unless a fill is needed, KX9X would normally just end the QSO with his second transmission (KX9X: "W1AW QSL KX9X") which is really the norm. The other commonly heard pattern is when a rover is working from a rare grid. If KX9X is the rover, that first KX9X line in the sample QSO doesn't happen; the rover often announces their grid when responding to a caller, and the rover's transmission is often followed by that of a new caller calling the rover. If we want new ops to recognize when QSOs have ended, it's good for them to know how 95+% of successful QSOs really go down so they can more quickly recognize the pattern. Also, there's generally no need to identify state, unless it's a rare one. CT may be one of the few worth mentioning, but most states are not. "With one hand holding your radio and the other holding your antenna, how are you going to log your QSOs?" Recording the pass isn't the only way to handle this, and may not even be the best approach for newbies, at least as a primary method. I've posted in the past about the benefits of operating with one's writing hand free, and logging by hand during the pass when receiving, transcribing calls and grids as I hear them. It would be a useful technique to suggest to new ops, particularly those who may not already be experienced phone contesters, as an alternative that might also help to improve their ability to work the pass. Reading a callsign you've already written down can be much easier than recalling one you only heard verbally. I cannot overstate how immensely this practice helped me. "If you are using two HTs, you will need a diplexer, which isolates your transmitted signal from your receive radio. Without it, you will likely overload the front end of your receive radio, which will make contacts impossible. Several manufacturers such as Comet and MFJ offer diplexers; the Arrow antenna has an optional diplexer that is stored in the antenna handle." I haven't needed any filtering when using two HTs and an Arrow to work AO-91 or AO-92. Also, the BLP-200+ filter may be a useful option to suggest in lieu of those larger diplexers if one is using an Arrow antenna. 73, Ryan AI6DO

Stolen Satellite Gear
by Michael Whitman 11 Jun '19

11 Jun '19

Good evening, AMSAT! This morning I discovered my personal vehicle had been stolen. Among the items inside, though hidden, was my complete satellite operation station. I understand this is a long shot, but please keep an eye out if you see any or all of these items up for sale in the near future: Yaesu FT-818ND (serial #: 8G910854) Icom IC-W32A (underside of battery has my callsign, I believe the side of the radio does as well but can’t remember) Bose QuietComfort 15 noise cancelling headphones Olympus LS-10 Linear Voice Recorder Arrow II Satellite Antenna (split boom) Also if you haven’t done it yet, let this be a good reminder to mark your equipment appropriately so it can be identified in case of loss or theft. 73, Michael, N4DCW -- Michael Whitman (904) 557-8243 images(a)michaelwhitman.net <mailto:[email protected]> Louisville, KY, USA

ICOM 910H issue
by Paul Overn 10 Jun '19

10 Jun '19

Hello, I have an issue on my 910H. On my 910h, I get “desense” on all linear sats except FO29. FO29:is clear and perfect, but any other linear I just hear my crakely voice until I tune perfectly to hear myself. Then I can still hear the static version of me behind the clear version. I have replaced all cables, diplexers, connectors and the Arrow. The issue still is there. I have also tried to used an MJF diplexer on the 70cm side to try to stop the desense, but it didn't help. Any thought as to what the issue could be? Paul Overn KE0PBR Twitter: @KE0PBR `·.¸¸.·´¯`·.. ><((((º>`·.¸¸.·´¯`·.¸><((((º>`·.¸¸.·´¯`·.. ><((((º> *****************************************

G5500 external control cable
by Bruce 09 Jun '19

09 Jun '19

I was just getting ready to solder up the G5500 external control cable. In the manual they provide a diagram of a 7-pin connector. However, the back of the controller is an 8-pin connector and Yaesu provided an 8-pin connector with the unit. Where can I get the information on the 8-pin wiring if it is not in the manual that was provided? An 8-pin connector would be numbered around the pin with the last number for the center pin. A 7-pin connector is numbered starting at the top, left to right for each row. This will connect to the LVB tracker which is labeled and easy to connect to. 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards AMSAT Board Member 2016-2020 ARRL Awards Field Checker (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0100z on Echolink - Conference *AMSAT* Also live streaming MP3 at http://www.amsatnet.com Podcast at http://www.amsatnet.com/podcast.xml or iTunes Latest satellite news on the ARRL Audio News http://www.arrl.org AMSAT on Twitter http://www.twitter.com/amsat
