Well, the Echolink admins would have to rely on people reporting those repeaters. I think it would also be necessary to work through IARU Region 1 for this as well. Also note that network disconnections don't solve potential interference by local users. 73 de VK3JED / VK3IRL http://vkradio.com

Hi Roberto, Your English is much better than my Italian so no need to apologise for it. I gather from the link you emailed me that the IR0CK repeater on 145.850 MHz is connected to Echolink again, it operates as Echolink node 488822 , see in Google English (R10 = 145.850 MHz): http://tinyurl.com/3mgw6x4 The decision of IARU Region 1 to establish a procedure that will work towards disconnecting D-STAR repeaters causing interference in the Amateur Satellite segment is very welcome. It does not address the issue of FM repeaters in the satellite segment but repeaters such as IR0CK (node 488822) depend on being allowed to connect to the Echolink server which I believe is run from the United States. I do not know who owns the US Echolink server or what their policy is on providing connections for nodes that deliberately cause interference to other services such as the Amateur Satellite Service. Does anyone know who controls Echolink ? 73 Trevor M5AKA --- On Fri, 2/9/11, Roberto <iw5bsf(a)alice.it> wrote: > Hello sorry for my English, so > perhaps more understandable > > The repeaters are licensed by the Italian Ministry does not > recognize the > IARU band plans, repeater stations are run by amateurs and > individuals > other associations that do not belong to 'ARI.The ARI has > already taken action > repeatedly with documentation from the Italian Ministry but > has not been heard, I enclose > letter of 22 -03-2011 and that is the only action is to do > an official protest of the IARU > and the ITU in relation to the Italian Ministry of > intervening directly with letters to the Editor > General TROISI Dr. Francis, to 'address: Directorate > General > Planning and management of radio spectrum - the Ministry > of > Economic Development Department of > Telecommunications > DIRECTOR-GENERAL. > > 73 de iw5bsf Roberto

OSCAR-11 Report
by Clive Wallis 02 Sep '11

02 Sep '11

OSCAR-11 REPORT 01 September 2011 This report covers the period from 27 April to 01 September 2011. The satellite has continued to operate in a very predictable way since the last report, and no changes have been observed. During this time the satellite has been heard reliably during its ten-day transmission periods. Excellent signals have been reported from stations located around the world, and good copy obtained from decoded telemetry frames. The easiest way to check whether OSCAR-11 is operational is to look at the General Satellite Status website http://oscar.dcarr.org/index.php . You can also calculate the operating schedule from the last switch-off time, which was 26 August 2011 at 08:00 UTC (approx), using 10.35 days off followed by 10.35 days on. Reception reports have been received from David VE3SB, Jerry WB5LHD, Toby MM0TOB, Colin VK5HI and Lee M0HOK. Many thanks to all and those who posted to the status website. Although eclipses occur during every orbit, the evening passes over the UK were mostly clear of eclipses, owing to the longer hours of daylight during the Summer months. This resulted in stronger signals during the evening passes. However, as winter approaches eclipses will now start to affect the evening passes. The on-board clock continues to gain, 26 seconds during the current reporting period, and 83 seconds since regular transmissions started at the end of August 2010. There is however a large accumulated error of 308.54339 days slow. This was caused mainly by the clock stopping during eclipses, when there was also an unknown drain on the power supply. The units of the least significant digit correspond approximately to seconds (0.86 seconds actually). The VHF beacon frequency is 145.826 MHz. AFSK FM ASCII Telemetry. The satellite is operating in the default mode, with a cycle time of 20.7 days. 10.35 days on followed by 10.35 days off. At the present time, while OSCAR-11 is operating in a predictable way, I no longer need direct reports or files by e-mail. However, could all listeners continue to enter their reports on the general satellite status website. This is a very convenient and easy to use facility, which shows the current status of all the amateur satellites, and is of use to everyone. Reports around the expected times of switch-on and switch-off are of special interest, especially for times 12:00 - 17:00 and 22:00 - 07:00 UTC, when the satellite is out-of-range in the UK . The URL is http://oscar.dcarr.org/index.php A longer version of this report report is available on my website, and new listeners to OSCAR-11 should read this for further information. The URL is www.g3cwv.co.uk/oscar11.htm . This page contains a links to the longer report, a short audio clip to help you identify the satellite and a file of the last telemetry received. The website also contains an archive of news & telemetry data which is updated from time to time, and details about using a soundcard or hardware demodulators for data capture. There is also software for capturing data, and decoding ASCII telemetry. If you place this bulletin on a terrestrial packet network, please use the bulletin identifier $BID:U2RPT156.CWV, to prevent duplication. 73 Clive G3CWV xxxxx(a)amsat.org (please replace the x's by g3cwv)

hi, i have used this satellite with limited results do to the battery condition a while back, this page http://www.findu.com/cgi-bin/pcsat.cgi lists PCSat as being used for aprs messages not just beconing? please correct me if i am wrong, but when sending a message over aprs it does sound like a position becon. i have also done this though the ISS also really cool. kc0zhf WY Amsat Area Cooordinator

NO-44
by Kevin Deane 02 Sep '11

So nobody cares that people beaconing on 145.825 are rendering NO-44 basicly useless. If there were not all these beacons people would easily be able to use this satelite. Kevin KF7MYK

Monday September 5th I'll be in DM57 San Miguel County Colorado working the following fm satellites: 1906z - AO-27 2044z - AO-27 2111z - AO-51 2248z - AO-51 Due to terrain these are the only satellites I'll be able to work. As always, I'll mail all contacts a QSL card no sase or return card necessary. Jim Adams - K0BAM

Thanks Roberto, very glad to hear it's on 144 MHz http://n8noe.ham-radio-op.net/WebInterface/ARCLUSTER/ArcSysopManual/ArcConn… has it listed on 145.975 MHz - must be out-of-date information or a typo.
