Using the Arrow ant.
by tjjapha＠earthlink.net 19 Aug '07

19 Aug '07

For WB2LLP and others, For $30, I found a terrific collapsable tripod at a photo supplies store. It's 17" long when collapsed, and weighs 24 oz, no problem at all in adding that to my portable carrying bag. There is a standard 1/4" bolt on the tripod that is normally used to screw into a camera. The Arrow has a hole that accepts a 1/4" bolt. The problem with this is that the Arrow will tip over the whole thing because it extends far forward and unbalances the tripod. So, instead of screwing the ant onto the bolt, put a 1" threaded bushing on the bolt, and put a photographic C-clamp holder into the other side of the bushing. The holder also has a 1/4" bolt. Then the Arrow (or some other ant.) just gets center mounted in the C-clamp. There's no apparent diminution of the Arrow's effectiveness. Hope this is helpful to some. It returns at least 1 hand to use in logging! 73, Tony, N2UN

Everyone, I must again ask for your patience. The July/August issue of the Journal, which should have been close to being in your hands by now, is still not at the printer. The reason is that I still have 3 full open pages without content. If you have any articles for the Journal please forward them right away. Thanks to all the authors that have contributed. I'll notify you when I release the issue to the printer. I apologize for the delay. 73, Ed Long WA4SWJ Editor, The AMSAT Journal

New Zealand consultation on joint 2.3 GHz and 2.5 GHz auction
by Trevor 19 Aug '07

19 Aug '07

This item is indicative of the problems Amateur operation on 2.3 GHz faces around the world. In the cause of New Zealand I don't believe they access to spectrum below 2396 MHz anyway and from a brief read through the documents it looks as though they will continue to retain access to 2396-2400 MHz.

eating crow about preamp
by Patrick McGrane 19 Aug '07

19 Aug '07

Greetings After 3 years and many dollars, I finally hear the FM satellites well. For the last year or so I used a mosfet preamp and a 7 element homebrew yagi canted up 15 degrees on a cheap tv rotator. Worked most of the time. This summer I had the dual band rig worked on. Its now very sensitive on UHF. George, wb2vun recommended the Advanced receiver research Gallium Arsenide preamp so I bought the switchable model to avoid burning it out with accidental transmissions. Now I have fantastic reception! So, to all those who told me to get a preamp, I'll say, you were right! but I'll also say, dont promise pie in the sky in the future. I learned many lessons. I'm also active on ao-7 and vo-52. I'm slowly preparing for the HEO's. I purchased a UHF all mode mobile rig from a freind and a VHF allmode on e-bay. I have preamps for both and some yagis. Looking forward to the success of P3E. I like the old proven design with the unity gain antenna arrays and the more sensitive receiver. Thanks to all the amsats for all the satellites. 73, patrick, N2OEQ

Can anyone here comment on the performance of the KO5E Eggbeater II antennas for use on oscar 50-52. Does anyone have personal experience with this configuration? I'd like to use them with my ft-847 as rotatable antennas are not an option here. Eric

AO-51 Telemetry & WOD
by Clive Wallis 18 Aug '07

18 Aug '07

Hi, Recently I've been listening to Echo AO-51 on 435.150 MHz., and looking at some of the data in the KE4AZN telemetry archive. I've found a lot of information about the satellite, on the web, but still have a few questions. Is there a schedule of the sequence of when the various types of data packets are transmitted? Looking at the archived data TLM appears to be transmitted every 15 seconds. Some of the packets I've received, mention WOD. Is there a schedule for WOD capture and transmission? Is the WOD archived any where? Any help would be greatly appreciated. 73 Clive G3CWV Hitchin, North Hertfordshire, UK.
