Re: EggBeater

by Bill Dzurilla

Steve, I have both a commercial and a homebrew Eggbeater and am disappointed with both, especially in light of its rather high price. Connected to my IC-7000 via an ARR mast-mounted preamp, performance is far less than with an HT and an Arrow. Guess an omni can't cut it, at least not from my QTH. Maybe if I could get it up higher, clear of all roofs, it would do better. I can make contacts at relatively high sat elevations, but can do just as well with a $10 dual band ground plane. My friend has an Eggbeater and the same preamp at a clearer QTH, and he hears substantially better, down to 10 degrees elevation in some directions. Good luck and 73, Bill NZ5N > > Hi Steve, > > > > It is surprising to read that you are not hearing > anything.

FW: Re: The Moon is our Future

We have met the enemy and they are us. WE need to do something. Yes, $15m is outta reach, but isn't there a cash prize for the first on-commercial moon landing?

I couldn't agree more - we don't need more of the same. If I want to sit back and have a two hour rag-chew with someone on the other side of the planet I will use Skype or my cell phone! Dreaming about what *might* be in space is a fun exercise. Actually doing something about it requires sending things to LEO because reality has dictated that's as far as we can afford to go. How's about we use some of that frustrated *imagineering* to come up with interesting new concepts at LEO? We don't need any more FM repeaters buzzing overhead, but what about more cameras downloading HD images, scientific payloads that monitor the ongoing climate change, payloads to study the Earth's magnetic field, etc. etc. Our own 'Twitter' messaging network from space...? The Apollo 13 creed of "failure is not an option" has completely infected the brains at AMSAT and this list. You want something at HEO or on the moon, cut a check for $15 million dollars and let's get on with it. Been waiting since 1996 for another AO-13 and I am getting too old to keep waiting. AMSAT is becoming completely irrelevant as it strives without success for the impossible mission and exhibits a shocking amount of leadership malfesance as it stubbornly refuses to recognize and adapt to realities in the launch business. I know, I know maybe NEXT year someone rich will die and leave us a boatload of cash. Or the bankrupt US government will suddenly cough up a billion dollars for some orbiting emergency communication system. In the meantime we have to stifle the truth because it might blow yet another *secret* deal that's in the works and *almost* a done deal, so let's not complain publicly and ruin it. Heard the stories, heard the lies, got all the t-shirts and ball caps. Whatever. -- Jeff, KE9V AMSAT-NA member since 1994, Skeptic that we will ever go back to HEO since 2002 _______________________________________________ Sent via AMSAT-BB(a)amsat.org.

presentation & demo yesterday

by Patrick STODDARD (WD9EWK/VA7EWK)

Hi! My presentation and demo for the Mesa Community College Amateur Radio Club (KM7CC) yesterday was a good way to spend the afternoon. This is a new club, and the club has tried to showcase different parts of amateur radio available to those with the entry-level Technician license. Satellite operating is definitely one of those things, and I was invited to give a presentation to the club. As part of that, I also gave them an on-air demonstration after the presentation on an AO-27 pass. The club is a small club, but there was a good turnout for a Saturday afternoon on the MCC campus. A couple of those in attendance already had their licenses, and a couple of others are in the process of getting their licenses. I had my assortment of portable equipment and antennas laid out on a table, showing what I use to work the satellites. After the presentation, we went outside to prepare for the AO-27 pass just after 2100 UTC. A few days ago, I asked if I could use the club's KM7CC callsign for the AO-27 demonstration. I was told I could. As we were going outside to prepare for this pass, I was told that the callsign had not been used on the air. As we set up a table for my equipment, I answered questions from the audience. Then, the main event... Once AO-27 started its 20-second packet burst, a couple of people were able to hear the downlink on their HTs as I heard it on my radio. I was able to make a call in the first moment of the pass, and make a few quick contacts. This was, of course, a busy pass covering most of North America. Jim ND9M was also on from the Colorado/Wyoming state line (grids DN80 and DN81), and I listened for part of the pass as stations worked ND9M from his rare location. I was able to log ND9M and a couple more QSOs before the end of the 7-minute repeater time. As all of this was going on, the audience listened and enjoyed hearing the club callsign on the air. KM7CC made 9 QSOs with stations across the continental USA and Mexico. Clint K6LCS even called me from the Palm Springs hamfest in California that he was at, and ND9M gave me a call as well. I apologize to those who were unsuccessfully trying to make a QSO with KM7CC on that pass. Club members were paying attention to the exchanges with the grid locators, and several of them had Icom grid maps I brought to the meeting to make sense of those locators. I will mail QSL cards to the 9 stations I worked. There's no need to send me - or the club - SASEs for the QSL cards. If you'd like to send a QSL card for a QSO with KM7CC, please mail the card to the address on QRZ.com for KM7CC. Thanks to Allen W7AS and the club for inviting me to their meeting, and for the use of their callsign on the AO-27 pass. It was a fun afternoon. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

DN41 ANYONE?

by Lee Ernstrom

I am thinking about making a treck over to DN41 for the 2259-2310 UTC AO-51 pass this afternoon which is just a couple miles to the east of me. Is anyone interested in that grid? I could set up on the DN31/DN41 line. The satelite will rise to 16 degrees to the east of me and I will have a very short window due to the Wasatch range of the Rocky Mountains to the east. Then, on the next AO-51 pass the satelite will be at 66.3 degrees. I would entertain that possibility also. I will commit to it if I have any takers. WA7HQD Lee Ernstrom Syracuse, Utah

Re: Yaesu FTM-350R

by Clint Bradford

>> ... It's not available yet in the U.S. ... only 1W on 220 ... It's been available for about three weeks in the U.S. It makes me wonder how/why Kenwood has been able to get full 5W on 2M, 220, and 440 with their little TH-F6a handheld, while all the other manufacturers cannot get more than a Watt or two on 220 from even their mobile multi-band rigs. Just played with one for a few minutes a couple weeks ago at HRO-Anaheim. I am not sure if it is true full-duplex, nor how sensitive the sub-band is for us. Clint, K6LCS
