K1ZZ's Reflections on WRC-12 - NanoSat/Picosat
by Trevor . 25 Feb '12

25 Feb '12

K1ZZ's Reflection on WRC-12 touches on the Nanosat/Picosat paper: "Successful handling of a potentially difficult future agenda item concerning pico- and nano-satellites (this topic is too complex to go into detail here, but it is an important one)" Nano and picosatellite resolution at WRC-12 http://www.uk.amsat.org/4950 73 Trevor M5AKA ---- Reflections on WRC-12 I returned home yesterday evening after a most memorable and successful 33 days in Geneva for the 2012 World Radiocommunication Conference and the first Conference Preparatory Meeting for WRC-15. It will be a while before I can put together a comprehensive report and a QST article, but I wanted to express the following thoughts before descending into the accumulation of work back here in Newington. In my tenure as an ARRL staff member involved in the International Amateur Radio Union since 1972, the 1979 World Administrative Radio Conference will always stand out as an extraordinary success. We still sometimes hear 10, 18 and 24 MHz referred to as “the WARC bands” even though 30 years have passed. The 2003 WRC ranks second because we managed something that had never done before:to move HF broadcasting out of 100 kHz of spectrum and thereby greatly improve the usefulness of the 40 meter band. No single WRC-12 achievement may match these, but there were so many highlights of this year’s conference that it is difficult to decide which of them was the greatest: · Joe Taylor, K1JT’s speech to the Plenary at the end of the second week of the conference with an outstanding introduction by ITU Secretary-General Dr. Hamadoun Touré, HB9EHT · The celebration of the 50th anniversary of theInternational Amateur Radio Club, 4U1ITU, in the magnificent Popov Room in the ITU Tower attended by past and present Secretaries General and Radiocommunication Bureau Directors · Our fending off HF oceanographic radars from being in or even adjacent to amateur bands · The new allocation at 472 kHz · An agenda item for WRC-15 to consider a possible secondary allocation to the amateur service in parts of the5250-5450 kHz band · Successful handling of a potentially difficult futureagenda item concerning pico- and nano-satellites (this topic is too complex to go into detail here, but it is an importantone) There were even some Amateur Radio accomplishments during the WRC, including: · The first 1296 MHz EME QSOs from 4U1ITU using K1JT’s software, with K1JT himself at the controls · More than 13,600 QSOs made from 4U1WRC · More than 3,500 QSOs made during the ARRL CW DX Contest from 4U1ITU Amateur Radio is just a small part of the world’s telecommunication community and is commerciallyinsignificant compared to the satellite and mobile broadband interests. Yet, we have achieved a position within the International Telecommunication Union as a respected radio service. This position was not attained overnight or through the efforts of a single individual or small group. It wasachieved through the shared passion and sense of purpose of an extraordinary band of people from many countries and diverse backgrounds, some with IARU titles and many not,nearly all of them volunteers, who have worked through the IARU over the decades to present a highly professional visage and to ensure that the participation on behalf of the amateur and amateur-satellite services is of a quality that is equal to that of any other radio service, and better than some. I can’t begin to tell you how proud I am to be a part of this team. 73, David Sumner, K1ZZ Chief Executive Officer, ARRL IARU International Secretariat 23 February 2012

mp3 recordings of SO-35 and UO-14 from September 2000
by John Brier 24 Feb '12

24 Feb '12

I am not subscribed to this list but I will check the archives as they are updated. This is a cross post from my blog, but I doubt anyone that may be interested will find my blog. Check the blog for full links to the mp3s. http://cupcakecarnival.net/2012/02/24/ham-fm-satellite-recordings-2000 Sometime in 2000 I got an Arrow II Satellite antenna. I used two HTs (hand held radios) (one for uplink and one for downlink) plus a tape recorder to record the pass. I would go out at night for a 12-15 minute satellite pass with all this gear and my Mom would laugh at me saying I looked like some sort of spy or something. Then I would endure the mosquitos while contacting stations all over the US, Canada and even a little bit of the Northern part of South America. It was a lot of fun. I ripped the audio from the tapes into mp3 a long time ago and shared it on the web but the site it was on is long gone so here it is again. I have just gone through and listened to the passes and written down as best I could all the callsigns, grid squares, state and names that I could make out. Let me know if you have any corrections or additions in the comments. All of these mp3s are under 2 Megabytes. I am John, KG4AKV and these were recorded from Wilmington, North Carolina, grid square FM-14.

On some passes I don't think I made any contacts! Odd. I did notice I was mostly putting out my call as opposed to calling other stations, maybe that is why. Regardless of what is in the recordings I remember making many contacts and having a good time. I think these recordings give you a good idea of what to expect if you haven't done an FM LEO satellite. It's fast so be prepared to make quick contacts.

Re: Preamps and Arrows
by k6yk 24 Feb '12

The short answer is yes ! It works very good. Every portable operation I've done was with an Arrow and SP-432-VDG and two HT's. One to transmit, one to receive. I ran the preamp off a spare HT battery, 9.6 volts. Worked just great. Also have done some portable operating with a Heathkit HW-24 using the same preamp and Arrow. Running all of it from a 7 amp-hour gel cell. The battery would last a couple of days, just using it on passes and running 10 watts on transmit. If you aren't familiar with the Heathkit HW-24, it's a dual-band mobile radio, 10 watts or 1 watt on 2 meters and 440, full duplex with memories, etc. If you find one used, it's a great little radio. It will also do cross-band repeat and with a VERY simple mod will do full coverage way outside the ham bands if you like to listen to other services. And yes it has P.L. and also scans. What else? They were around $600 new but I've seen them for around $100 at times. I've had mine for about 20 years and it's still perking right along. 73, John, K6YK On Thu, 23 Feb 2012 21:32:24 -0600 Tom Schuessler <tjschuessler(a)verizon.net> writes: > Has anyone used a preamplifier in a portable setup based on an Arrow > cross yagi?
