RSGB Joint Response to EU Commission Galileo Green Paper
by Trevor 12 Apr '07

12 Apr '07

On Friday 6th April a joint response was submitted by RSGB, AMSAT-UK, UK Microwave Group and the British Amateur Television Club to the European Commission Green Paper on Satellite Navigation Applications. The Galileo Global Positioning System, expected to be fully operational between 2010-12, will make use of 1260-1300 MHz. This is a key segment of the Amateur 23cm band used for ATV, Repeaters, Satellites, EME and weak signal terrestrial communications. The response document can now be seen on the web at http://www.g3psm.net/07_04_06_RSGB_Response_to_Galileo_Green_Paper.pdf Galileo green paper on satellite navigation applications http://www.southgatearc.org/news/december2006/galileo_green_paper.htm Potential Interference To Galileo From 23cm Band Operations http://www.southgatearc.org/articles/galileo.htm 73 Trevor M5AKA --------------- Daily Amateur Radio RSS News: http://www.southgatearc.org/ Email your news items to: editor at southgatearc.org News On Your Website: http://www.southgatearc.org/rss/index.htm News On Your PC: http://www.southgatearc.org/rss/newsreader.htm Upload Your News: http://www.southgatearc.org/news/your_news.htm --------------- ___________________________________________________________ Yahoo!

Re: IC-910H opinions sought
by William Fry 11 Apr '07

11 Apr '07

Hi Tim, I researched all the satellite radios before I bought one, and had one of the first 100 released to the market. It took a while to get the learning curve, but think this is one of the best Satellites radios out there, bar none, execellent, this is my opinion. Don't think you can go wrong with a 910H. I didn't need an HF radio as I already have one, just wanted a good satellite radio.

Re: New Zealand 2.3 GHz Radio Frequency Auction
by Grant Hodgson 11 Apr '07

11 Apr '07

The auction document makes no mention of whether the band below 2396MHz will still be available for use by the Amateur service; it merely states that the band 2396-2400MHz WILL be available to the amateur service. Could someone in NZ clarify the situation re. amateur use below 2396MHz? This auction does not directly impact users of the amateur satellite service which has an allocation 2400-2450MHz. The 13cms band is now getting very fragmented due to geographical restrictions as most EME'rs will testify. However, there is suggestion at IARU level that both the amateur service and the amateur satellite service should try and obtain a worldwide allocation of a few MHz of spectrum, on a primary basis if possible, between 2390 and 2400MHz. This will not be a quick process, but in the long term could be a major benefit to radio amateurs the world over if it could be achieved. regards Grant G8UBN

Value of Icom Delta100 (2m/70cm/23cm)
by John Geiger 11 Apr '07

11 Apr '07

I am looking at putting an Icom Delta 100 triband transceiver up for sale soon. It covers 2m/70cm/23cm with triband receive. I am not sure exactly what it is worth. Can anyone give me an estimate as to its value, or does anyone care to make an offer on it? 73s John W5TD ____________________________________________________________________________________ We won't tell.

New Zealand 2.3 GHz Radio Frequency Auction
by Trevor 11 Apr '07

11 Apr '07

New Zealand 2.3 GHz Radio Frequency Auction In November 2006, the New Zealand Cabinet decided to reconfigure the 2.3 GHz spectrum rights and to allocate new rights by auction. The Government is planning to auction spectrum at 2.3 GHz in late May 2007. The rights expire in 2010 but some of the rights may be available for access before this date. The reallocation of the band will provide increased certainty for investment in new broadband wireless access services using this spectrum. The Ministry of Economic Development seeks any comment from industry on the proposal arrangements before they are finalised. Any comments must be submitted to the Ministry by 5:00pm on 27 April 2007. For more information, please contact: radiospectrum(a)med.govt.nz.

ANSR-37 balloon launch on 14 April 2007
by Patrick STODDARD (WD9EWK/VA7EWK) 11 Apr '07

11 Apr '07

Hi! Here is an announcement from Arizona Near Space Research (ANSR), about an upcoming balloon launch. Along with the various payloads on this flight, there will be a 2m/70cm cross-band repeater that functions very similar to those on FM satellites. Launch site has not been determined yet, but this group usually launches from sites in the southern part of metropolitan Phoenix or in central Arizona between Phoenix and Tucson. The cross-band repeater, when in flight, can cover hundreds of miles/km. Stations in Arizona along with portions of neighboring states (Nevada, California, Utah, New Mexico) and some parts of northwest Mexico (northern Baja California, northern Sonora, northwestern Chihuahua) are workable. You may see coverage maps of a typical ANSR balloon flight at: http://balloon.wd9ewk.net/ Unlike with the FM satellites, there is no Doppler effect to deal with on these balloon flights. This could be a good way to get ready for working FM satellites, or testing a station that has already been used to work those satellites. Good luck and 73! Patrick WD9EWK/VA7EWK - Phoenix AZ http://www.wd9ewk.net/ (ANSR-37 launch announcement follows) Arizona Near Space Research (ANSR) is pleased to announce the flight of ANSR-37. This high altitude balloon flight will take place on Saturday, April 14th at 9:00 A.M. (1600 UTC). The launch site is to be determined depending on the predicted winds aloft. Follow up announcements will designate and expand launch site information as the flight date nears. The balloon will be a 3000-gram weather balloon, filled with helium. The expected burst altitude will be 90,000 feet or more. The flight is anticipated to last about 2.5 hours from launch to touchdown. In addition to the ANSR standard payloads, this flight will feature four payloads designed and built by University from across Arizona. Participating schools include Northern Arizona University (NAU), Embry Riddle Aeronautical University (ERAU), Arizona State University (ASU) and the University of Arizona (UA). This flight is the second ASCEND! flight of the school year and is sponsored by the Arizona Space Grant Consortium. ANSR thanks AZ Space Grant for another opportunity to fulfill our mission: Promoting Science and Education Through Amateur Radio and High Altitude Balloons. The ANSR Cross-band repeater will be aboard this flight. Stations, especially those distant from the balloon, are invited to use the repeater when the repeater is not in use by the chase and recovery team. Feel free to use the Yahoogroups Ballooning site: http://groups.yahoo.com/group/Ballooning/ to coordinate dx schedules. Peak altitude should be about 10:30 to 10:50 A.M. MST (1730-1750 UTC). The following is the payload frequency plan: APRS Beacon 445.950 MHz packet at 5, 25, 35, 55 seconds UTC time via KD7LMO-11 Cross Band NB-FM Voice Repeater Input: 145.560 MHz/162.2 Hz PL tone Output: 445.525 MHz Linked to IRLP Node 9255 APRS when repeater not in use on 445.950 MHz at 10, 20, 40, and 50 seconds UTC time via KD7LMO-11 Landing prediction after burst at 15 and 45 seconds UTC time via KD7LMO (no -SSID) Pico Beacon APRS 445.950 MHz packet at 0, 30 seconds UTC time via KD7LMO-11 Our mobile cross band Digipeater will repeat the APRS data to the 144.390 MHz standard APRS frequency and thus will be I-GATED to the Internet for out of area trackers. You can track the flight using either of the following links: http://www.findu.com/cgi-bin/find.cgi?kd7lmo-11 http://map.aprsworld.net/kd7lmo-11 Be sure to check this site for updates to this announcement prior to the flight.

partable thoughts
by tjjapha＠earthlink.net 11 Apr '07

Steve VE3SAX-- I use a 2 tripod portable setup for FO-29 (and a wee bit of AO7). Also using 2 FT-817s and, for 2 mtrs, a 20 watt battery powered amp. Antennas are the elements of an Arrow, split between two booms, one band on each tripod. It's all carried in 2 hands (and a shoulder) to the operating site! (Contrary to some reports, I've found that 5 watts isn't enough for AO7, and I'll probably add a 20 watt amp for 70cm. too.) I suggest using simple RG-8X. The runs are only 6-10 feet long, and loss is easily manageable. It's also way easier to handle, even in small lengths. At those lengths, even RG58 is tolerable. Preamps for both bands, mounted at the antennas, are great to have, if not an absolute necessity. Have fun and see you on the birds. 73, Tony, N2UN
