Re: FYI -- One Laptop per Child (OLPC) Opportunity
by Tom Clark, K3IO 22 Jan '08

22 Jan '08

(I posted this a couple of days ago, but it was never released from amsat.org limbo. So I resend. My order for OLPC went in today -- they accept either PayPal or plastic -- Tom) Another thing I gleaned from the OLPC wiki is that it supports FORTH (start at http://wiki.laptop.org/go/Forth_Lesson_0). Karl (DJ4ZC) designed Phase-3A back in the late 1970's and the onboard computer (IHU) used the computer language that Karl wrote called IPS (Interpreter for Process Structures) based on FORTH, but with German syntax and multi-tasking real-time support. Several of us (W0PN, W1HDX, ZL1WN, DB2OS & I) ported the German "dialect" of IPS into English and the "Gerglish" IPS has served as the basis for running all the Phase-3 IHUs up thru AO-40 (thanks to the efforts of W4SM and G3RUH). IPS is also planned for P3-E (N4HY already has it running on the new IHU) and probably P5. As another possible AMSAT/OLPC synergy, I can easily envision the OLPC Forth kernel being adapted to real-time control tasks with the addition of Karl's "chain". Although it is really modest compared to the normal laptop, Nick Negroponte and his team has really come up with a platform that has amazing possibilities! Meanwhile, ASUS has introduced their commercial Linux-based "Eee" miniature notebook that is already available ($399 from Amazon <http://www.google.com/pagead/iclk?sa=l&ai=BuJiyAGg3R9XlK4iaeuyDjLIMqprePM7t…>) -- Just Google ASUS Eee <http://www.google.com/search?q=Asus+Eee&sourceid=navclient-ff&ie=UTF-8&rlz=…> or see the Eee wiki entry <http://en.wikipedia.org/wiki/ASUS_Eee_PC#Storage> for details. 73, Tom

hamfest/demo tomorrow (1 December)
by Patrick STODDARD (WD9EWK/VA7EWK) 30 Nov '07

30 Nov '07

Hi! I will be part of the AMSAT table at the Superstition Amateur Radio Club's hamfest in Mesa, Arizona, tomorrow morning. The hamfest is at Mesa Community College, on Dobson Road between Southern Avenue and the US-60 freeway (exit 177). The club has a web page with hamfest info at: http://wb7tjd.org/hamfest/ I will be doing AO-51 demonstrations during the 1515 and 1649 UTC passes from the hamfest as WD9EWK, weather permitting. It is currently (Friday at 2020 UTC) raining here, and there is a chance for rain tomorrow morning. Unless the hamfest site turns into a swamp and/or there is lightning in the sky tomorrow morning, I hope to be on for both of those passes. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Re: [eu-amsat] Satellite DX
by John W Lee 30 Nov '07

Speaking of satellite DX, I don't know if I've seen a messge about this or not. There is a group of folks down at XF4 Revilla Gigedo for at least a week now. XF4YW (XE2YW) has been on the FM birds from time to time. They will be there for several more days. That would be grid DK48 off the west coast of Mexico. 73, John K6YK

Re: Satellite Rigs, whats available
by Reicher, James 30 Nov '07

30 Nov '07

I'd recommend the Yaesu FT-847 over the Icom for these reasons: 1. The 847 has 160M thru 70cm in one box. This means that when AO7 comes up in mode A, you don't have to use a separate rig for the 10M downlink. You'll have all the other bands as well, 160, 80, 60, 40, 30, 20, 17, 15, 12, 10, & 6 meters, as well as 2 meters and 70cm 2. The 847, which is out of production, can be had for much less money than an IC910. I got mine for about $850. I typically see 910's selling used, without the 1.2GHz option, for about $1,000. 3. You can more easily find and install a different mike on an 847, since they don't require a special type of mike. 4. The IC910s I've dealt with tend to develop a situation where the displayed frequency does not match the actual frequency. 2 meters is usually about 3 KHz off while 70cm gets about 9 KHz off. This can get nasty to use for someone who's not familiar with the rig. 5. CAT control of the rig is as simple as running a null-modem cable from the back of the rig to a serial port on your computer. The 910H requires a CTV or whatever they call it to interface to your computer. 6. While it doesn't have a 1.2GHz option, you can still use a transverter, which tends to be much less expensive than the Icom 1.2GHz optional unit. 7. It is also packet-ready, as well as all the other digital modes. 8. DSP filtering is built-in and comes standard. 9. Less menu driven than the Icom unit. In short, the 847 is more versatile, easier to interface with the rest of your station, and less expensive than the Icom. 73 de W0HV, Jim in Raymore, MO (ex-N8AU) Light travels faster than sound... This is why some people appear bright until you hear them speak.

After borrowing a 910 for Field Day one year, I immediately went out and bought my own. I didn't even look at anything else, and I love it. Sensitive RX, plenty of TX power when needed, 1.2 GHz with the optional UX-910, easy to interface to the computer, 9600 packet-ready, and great for terrestrial work as well. I have the DSP and high-stability options in mine, as well.

I have also heard it is questionable here in the USA. While in mode A (AO7) I have made several attempts to shake loose a JA or some northern UK gent where I have a very short window at times, even a piece of Europe for some footprint streaching fun. In the days of RS15 I was able to do this fairly regularly and had many sub 4 degree QSO's to the other side of the footprint. It takes good and quick operation and a competent guy at the other end. My opinion is," if this were easy, everyone would be doing it". Generally speaking we all love a challange, at least that's what keeps my passion for amateur radio alive. I have a fantastic mentor in Joe K0VTY as well a Clair VE3NPC both of whom have forgot more that I can ever learn. There's Central and northern South america of which I have hever hear a peep out of. I had a new aquantnce in the shack yesterday who was considering satellites. AO7 (mode A) came up through the mid west and I had a nice chat with Joe K3SZH ( who I think probably owes the bird hihi). This visitor just lite up , like the perverbial bug latched on. Can we get a front page blurb in QST on the assets of AO7? This is what got me going back in the days of RS10 and 12/13. When I'm on the HF bands at times I will "steer" the converation to satellies and attempt to simplify this "complex" mode that many believe it is. It is incumbenton all of us to "push" this fantastic method. 73 Bob W7LRD Seattle -------------- Original message -------------- From: John Hackett <archie.hackett(a)hotmail.com> > > Gents, > > I suggest each and every one of us sends the relavant mail to every national > society requesting it be published in their magazine/newsletter to attempt to > generate satellite interest in the countries where there is coverage but no > operation. > > There are several countries where a potential newcomer could "rake-in" the > satellite certificates quicker than you can say "AO-7 is a damned good satellite > when it's used properly". > > Again, I've batted this over to the States in case they suffer from the same > kind of inactivity in some of the states. > > Let's educate! a few new operators ... not blind 'em with science. > > 73 John. > > To: eu-amsat(a)yahoogroups.com > From: sv1bsx(a)yahoo.gr > Date: Fri, 30 Nov 2007 12:30:24 +0200 > Subject: Re: [eu-amsat] Satellite DX > > > > > > > > > > > > > > > > > > > > > > > > Good morning John & Group, > > you have absolutely right about DXing and AO-7.

Need Daiwa CN-520
by Anthony Japha 30 Nov '07

30 Nov '07

Greetings, Anyone have a Daiwa CN-520 SWR meter they'd be willing to sell? It's the small (2 3/4' square) meter for HF with no controls on the front and 200 watt and 2000 watt scales. I'd like to build it into a tuner. Tnx and 73, Tony, N2UN
