An amazing AO-7 QSO last week, Brazil to Belgium
by Mark Lunday 15 Jun '09

15 Jun '09

Brazil to Belgium. Hey Tim, N3TL, you have been doing some of this type of planning with great success. What is the longest QSO you have achieved? What tools are you using for planning on the low passes? Your efforts are fascinating and we would like to know more. http://www.southgatearc.org/news/june2009/ao7_brazil_belgium_contact.htm Mark Lunday WD4ELG <mailto:wd4elg@arrl.net> wd4elg(a)arrl.net <http://wd4elg.net> http://wd4elg.net

AO-51 Basement operation!!!
by Luc Leblanc 15 Jun '09

15 Jun '09

Hi I just try AO-51 V/S mode this morning 0700am pass. I was checking a new S band beam and it was a success nearly all the fades disappear comparing to my former WMAX beam. But i was not able to uplink to the satellite only to discover a frightening flaw in my setup i was transmitting in the same VHF port that i used for my 2.4GHZ downconverter. Too early in the morning and probably not awaken enough i immediately stopped transmitting and OH surprised the DC does not blow up? But what about the 847 finals...they survive about 10 transmission... In the middle of the pass and the DC still working i cannot switch my rig/antenna fast enough i take my HT DJ-580T with his rubber duck antenna and i punch the uplink frequency then and i called Doug KD8CAO who was calling in the void since the beginning of the pass and at the same time i heard my downlink he answered me back...My Alinco was at 5W. But the amazing part "i was in my basement..." It is a living proof that the hard part is the receiving side. My last basement record was on AO-16 50w on a dual band mobile antenna on a metal file cabinet. P.S. i will buy a lotto ticket today i feel the stars where on my side this morning:) "-" Luc Leblanc VE2DWE Skype VE2DWE www.qsl.net/ve2dwe WAC BASIC CW PHONE SATELLITE

Re: equal time

Tim, N3TL, we worked several times during my trip.( I just saw your post.... I have too have amnesia sometimes ;)I have your QSL cards and you are in my Log from my Trip. I agree with most of what you said but I think you misinterpreted my use of the word "sport". I meant it in the context of working the same stations over and over again, from a fixed station to another fixed station. A satellite in the end it is just a repeater with the added limit of a small working window and the usual Doppler shift. Perhaps we should call it the "art" instead of "sport" of working a satellite. I know you have perfected it very well and I have enjoyed reading many of your posts as I am locationally challenged at home living in an apartment in Chicago. Not conducive to working the birds unfortunately.... I checked QRZ.com and many of the stations I worked had similar setups to mine. Pretty much an HT and small antenna: Arrow or Elk. Also it was never my intent to hog any of the satellites for the duration of my operations. That would not be the spirit of a "True Satelliteer!" (a quote from WB2OQQ) There were many stations who needed EK99 but never managed to get through. I just wanted to make a few stations happy for a new one. I had the option of going full power but I chose not to on the FM birds. Perhaps I should next time. I am already looking forward to my vacation next year, planned from Hawaii as of now. Now that is going to an operational challenge. Sebastian, W4AS, thanks for your kind words and the opportunity to work you to. I sure wish I had your setup. I live in an apartment in Chicago so few opportunities to operate from a fixed location. I agree K5D could have done a better job in their satellite operations. At minimum a simple rotor and even a fixed antenna at 15 degrees with a two radios on all the current satellites would have worked better and would have probably provided more operators the chance to work K5D. A fulll blown setup with an AZ/EL rotor and doppler tracking would have been the perfect setup considering all the other equipment that was brought to the K5D DXpedition. It would be interesting to understand what planning was done for satellites operations for K5D. I won't speculate. FM satellites may not be the ideal satellites for a DXPedition but not everybody has the gear to work the linear brids. I think it comes down to the DX operator. FM satellites can be worked on a DXpedition. I had some pile ups on numerous passes and I was able to work many stations with some discipline and good ears. It takes an operator with contesting experience to work a pile up and maintain order. Still it is very challenging especially on such operations as K5D. Not sure what to do in the future. I agree with Tim, everybody has their own motivation on the birds. Some go after VUCC, some like to ragchew, some like to say good morning or good day to their friend a few states over, some like to chase DX, some to work new or a new rare gris, some like to be DX or be a in new grid. What ever the motivation it is all about having fun with our hobby, but it is also about operational excellence. Sebastian mentioned the many new users who get on the birds and don't operate correctly. It is up to all of us to be their elmers online and offline and make the new operators > good operators and good operators> better operators if our hobby is to survive. Thank you both for your kind and spirited opinions. Tim, I wish I could work you from my house in Spain from EA6 in JM09tb when I am there in October. Seems AO7 is just out of reach from the predictions I ran. Sebastian, I agree if there is a person who could work Japan on AO-51 it would be Tim, which I know is physically impossible. I appreciate all Tim has done and is doing for the hobby and the AMSAT community! Let's keep having fun and keep our arms open to new operators! 73, ;) Adrian AA5UK ZF2AE & ZF2AE/ZF8 ________________________________ From: Sebastian <w4as(a)bellsouth.net>.

Next, I think because of the things you have said, and the recent issue with the K5D operation, we have learned that attempting to put up a rare country on an FM satellite just doesn't work out. There are simply too many stations on AO-51. Why - because it's easy to do. SO-50 because of the timer and PL tones, is more difficult. A lot of hams don't realize that FO-29 is back in service, let alone AO-27; and AO-27 is only on for about half the pass on the USA. AO-16 has been off the air for months, and hopefully we will get it back sometime. The SSB birds are more difficult since it requires additional equipment, as opposed to an HT or two and a small handheld antenna (with the exception of Tim who could probably work Japan on AO-51 even though it's not in his footprint!) Tim knows I'm joking. AO-51 is over used. And yes there are a lot of people who may not necessarily run high power on there, but have large antennas of which I am one of. I won't apologize for having outdoor directional high gain antennas controlled by an LVB tracker. My antennas are from the days of AO-10 & AO-13, and I don't have the ability to change to RH, LH circular polarization; I use axial polarization. Yes there are some who are using handheld antennas with roughly the same amount of power that I am; but who's going to be heard (even with my 115 feet of LMR400)? Then there are those who believe it's a trivial task to setup a full duplex HT with a hand held antenna and be heard. It's not easy. I've tried it, and have concluded that it takes a lot of time to learn the 'tricks of the trade'. At least once a week, I hear a newcomer on one of the birds calling CQ. And people come back to them, but that newcomer can't hear them, because they aren't aware of doppler, etc. Then there are some who use 'high' power, I would say 50+ watts, but perhaps they need that power because they are using vertical antennas or eggbeaters, with 150 feet of RG-58 Radio Shack coax. And there are some who either use high power, or have defective rigs (or both), and make it difficult for others to hear due to their spurious emissions because they want to have more contacts than anyone else. So what's the answer. Those who aren't active on the birds because they are fed up will say we need a HEO. Those that are active on the birds don't have to say anything. They already know the problem. I would like for someone to explain to me why they disagree that what we really need are more LEOs. 73 de W4AS Sebastian On Jun 14, 2009, at 6:03 PM, Adrian Engele wrote: > As many of you know I operated as ZF2AE from EK99 back in late March and early April during my vacation from Grand Cayman and Little Cayman. I received numerous direct requests to have a sked as EK99 was needed for their VUCC awards. I made a big effort to meet all these requests received prior or during that trip and in most instances I was successful. As a portable, I worked AO-51 and SO-50 with just an Arrow Antenna with an ARR preamp and 5W with my VX7R. I also worked other stations on AO-7, FO-29 and VU52 using the same setup but with my FT857D with 10 Watts instead. Let me tell you setting up as a portable station to work the linear birds is time consuming and required a big effort everytime. I was on vacation and Hamradio was a secondary activity. > > After my return, I went through my recordings it was clear that there were many missed opportunities to work certain stations for their requested skeds . Why was this? In most cases, it came down to stations both domestic and international that are NOT LISTENING or not leaving enough space between calls. Also it was clear these same stations were calling the same stations day in and day out. What is the sport in this, working the same stations and the same grids over and over again; especially when a DXpedition is ongoing and others need to work that grid. I had numerous passes where I could not get once into an FM satellite during a planned sked. In some cases, I only managed one or two contacts. It was frustrating to say the least. Out of the 45+ passes I completed during my trip there was only one satellite pass that was disciplined, operators listened, called in order and over 15 contacts were worked in sequence with zero interference and many happy > operators. > > I encourage operators with deluxe satellite stations running power with full computer and rotation tracking to let more modest stations have their fair share of opportunities to get into the satellites. You may disagree with this concept, but I would like to remind the readers the FCC mandates that minimum power should be used to make at all times in to establish a contact. > > During my trip and upon my return, I received countless emails and QSL cards thanking me for activating a new country and a new grid.

Appreciate that Pierre , But looking at the URL it does state the Operational OSCAR Satellite Status Summary.. It does not state any date, apart from a copy right that dates 2004 - 2006 that is seen as misleading maybe.. What I would like [if possible] in reality what is available / in use / in the real world…. I would like to disseminate this in brief notes in our VHF Scene in our National association magazine… PS over the years, many contacts on OSCAR 6 and 7A + 7B both modes … 7B only recommended narrow modes – but with varactor tripler slipped the odd FM contact in … Best DX out of ZL into ZL5TAA [operater Ted ZL2TAX orbit 9679] on OSCAR 7 mode B - 1976 – and KC4AAA with OSCAR 6 before that .. many others DL on a A0-40 – 7minute window – 13cm – 70cm downlink / uplink … QSL’s in the shoe box.. A bit about myself to the reflector – not sure how many on – thanks again Pierre 73 Steve ZL1TPH --- On Mon, 15/6/09, Pierre van Deventer <pierrevd(a)icon.co.za> wrote: From: Pierre van Deventer <pierrevd(a)icon.co.za> Subject: [amsat-bb] FW: Satellites operation To: AMSAT-BB(a)amsat.org Received: Monday, 15 June, 2009, 6:25 PM Have a look at the Amsat NA site: http://www.amsat.org/amsat-new/satellites/status.php I think all the info you need. 73, Pierre ZS6BB -----Original Message----- From: amsat-bb-bounces(a)amsat.org [mailto:amsat-bb-bounces@amsat.org] On Behalf Of Julie & Stephen Sent: 15 June 2009 07:05 To: amsat-bb(a)amsat.org Subject: [amsat-bb] Satellites operation New to SAT – BB (one week) Could I please ask – how many SATs are currently active carrying transponder for amateur radio voice communication.

equal time

To the regular repetitive users of Echo Please refrain from hogging the satellite every pass for multiple contacts. I cant get into the satellite anymore and I am not going to use the amplifier to fight everyone. Sorry if you are offended but you need to be told. My support of amsat is directly proportional to my ability to use the satellite. pat

My apologies

Hey everyone, I need to stop relying on my memory. Someone pointed out that I had, indeed, worked Adrian while he was operating as ZF2AE. My log reflects that we worked on AO-51 and SO-50 while he was there. My apologies to all for that mistake in my eariler response to Adrian's post. I didn't recall working him when I wrote that. 73 to all, Tim - N3TL

Help - no antennas allowed
by john heath 15 Jun '09

15 Jun '09

Hi Satelliters, Moving QTH soon and expect to be in an area where there are no external antennas permitted. Does anyone on the list have actual experience of working satellites with antennas mounted inside the roofspace? I would be very interested to hear of your experiences and what type of antennas work best. 73 John G7HIA
