[amsat-bb] Re: kpc-9612 plus and online_kiss.exe
Hello Nadar, Ken, and Kevin. If you cold send me a text file of your settings, I could take a look to see what is happening. There is a command that you need to set from 'newbie' mode to 'expert' for the KPC-9612 to accept and keep the settings that you change. I am not near my KPC-9612 manual, so I can not give you the exact command to check to make sure. Email direct please. James W8ISS ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: 2.4GHz broadband router on satellite?
Lee and those who have responded so far, Those are the questions that would need to be answered before even considering this 'novel' idea. I use the WRT54GL as a reference since that is what I am familiar with. The WRT54GL would need to be almost redesigned because of space radiation conditions plus it may just not have enough output power to even be considered especially with trying to fit it into a microsat or smaller frame and then finding a suitable launch. Could the satellite utilize a modified 'backfire' antenna (referencing AO-40 2.4GHz antennas) that utilizes dipoles offset from the surface on every side and then use the surface of the satellite itself for gain? As for HSMM-Mesh, this maybe the software to consider for something like this as its robust enough for what I have played with three WRT54G around my area (EN82jg), both mobile and stationary. My laptop (a Fujitsu Lifebook T4020) is sensitive enough to pick up one 54g half a mile away using just the supplied antennas and if I add a BBQ style dish (from my AO-40 reception days) to replace the supplied antenna, I can almost quadruple that range. Granted the laptop and 54g are both at ground level and have a lot of obstructions. Still have to take it out to one of the local parks to see what I can actually get for range with no buildings. With the laptop being so sensitive, I can connect to the local McD's free wi-fi almost half a mile away better than I can my d-link router in the basement. As for frequency usage, going by the 'slide-band' chart (available at http://www.hsmm-mesh.org), there are 6 available 'channels' that fall in the satellite sub-band the way I am interpreting FCC rules. If the 'slide-band ' crystal modification is done, that gives 4 'channels' for use. Something to consider there about 'channel' hopping in the software. Greg, KO6TH, brings up about the timing protocols. Maybe the HSMM group or TAPR would consider looking at the protocols and maybe modify them much like AX.25 was done for packet back in the 1980's. Mark and Drew bring up about noise levels being unacceptable on a few of the lower bands. This might be mitigated with the use of the 'slide-band' modification by changing out the 20MHz crystal for a more appropriate frequency. As I noted earlier, more about the 'slide-band' mod for the 54GL is at the hsmm-mesh pages. So if some of these obstacles can be 'overcome', would this be a 'viable' consideration? Could something like this be utilized to gain the faster input speeds that are wanted for uploading/ downloading images, files, and maybe store and forward systems that could tie into the regional packet networks utilizing JNOS 2.0, WinLink, and FBB. I just miss having something that is more than just APRS-related on the satellites. This in no way is a knock on the present 1k2 sats, its just that my KPC-9612 has been VERY under-utilized since the mid-1990's and I miss having that fun :( I am not a rocket scientist, electrical engineer, or a sat designer. These are just personal thoughts to see if this 'idea' is even feasible. My thoughts could be seriously flawed and skewed and totally 'out of this world' to say. For all I know, this might be one of those bright ideas that would work better with a placement on the lunar surface as long as it doesn't interfere with EME work and can survive the harsh environment there. That would be a TOTALLY separate discussion in itself alone.

[amsat-bb] Re: Latest AMSAT Journal
Hello Joe and the list. If I can explain a little about how bulk mailing works, it might help explain some issues that people have with getting the journal. I work for a printer that does bulk mailings also and this is how they do things. AMSAT's printer may do it a totally different way than how my employer does it. First, It all depends on when the mailer gets the printed copies. There may be issues with paper used, when the files arrive, scheduled deadlines met on time, things like that. Second, the sender supplies a file with names and addresses that need to be printed onto either labels or onto the printed material in a certain space. This takes about anywhere from 30 minutes to a whole day (equipment issues) to set up aligning the print heads. Each process has its own procedures and differs between mailers. Third, depending on what the volume (quantity) is, it could take a day to a week to print names and addresses onto the printed material. Fourth, keeping the addresses sorted so that they are going to the right destination can get complex sometimes. Fifth, after everything is sorted by zip codes and destinations, then comes shipping via semi to the separate sort facilities across the country and outside country destinations. Yes, depending on quantity, bulk mailing gets shipped to sort facilities across the country by contracted carriers. Sixth, it could take as much as a week to get from the mailers dock to a sort facility on the other side of the country depending on where the mailer is located. If you look at the mailing label area on your journal next time, you'll see that little square that has this saying in it: Periodicals POSTAGE PAID At Silver Springs, MD and at additional mailing offices that means that it has gone from the mailer to at least one sort facility in the path before it gets to your local post office and your home mailbox. There is also meeting the criteria of how the USPS wants things sorted and weighed and. The list is endless currently. My place of employment has had the USPS reject a load because it either weighed one pound more or less than what is stated on the documents. The USPS also has guidelines that have to be met about thickness and weight of paper. That can hold up a mailing also. This is not to say that this is how AMSAT does the mailing of the journal. I am just stating how its done at my place of employment to give everyone an idea of what it takes to mail the Journal each time. Things do change each time the Journal is mailed so that has to be taken into account each time. Proposed deadlines have to be met to keep things flowing. If one deadline is not met, that can hold things up by a week or more. The times I gave are based on a mailing of several hundreds of thousands having to have addresses printed onto them. You also have to remember that the printer that AMSAT uses has to make deadlines also. The printer could be the same business that does the mailing which does help. AMSAT only has to do roughly almost ten thousand printings of the Journal each time. This takes time on the presses to set up. Based on where I work, the Journal would go onto the sheetfed press not the 4 color offset press because of the quantity amount. Which means a little bit more cost in paper, press time, and setup. Then it moves out to the bindery department to be folded, cut, and stapled to its final size for the mailing department. I hope this explains some about why one person may get a journal before another person does. I know it doesn't explain everything but it gives everyone an idea of what it takes to get the journal mailed. James W8ISS ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.

[amsat-bb] Detroit Maker Faire special event station N8M
Hello Everyone. A group of Amateur Radio clubs here in the Detroit area are going to be hosting a couple of outside booths at the first annual Detroit Maker Faire this weekend - July 31 and August 1. We have procured the special event call sign of N8M for usage during event times of 9:30 am (1330 UTC) to 8:00 pm ( UTC) on Saturday and 9:30 am (1330 UTC) to 5:30 pm (2130 UTC) on Sunday. I can not give you details currently on what HF frequencies the station will operate on but we will have Satellite capabilities for most of the FM and SSB satellites during these time frames. We will only have receive capabilities until 1:00 pm (1700 UTC) on Saturday. After that time, we should be able to work almost anyone we hear. Hope to hear and work you this weekend.

From the AMSAT-NA by-laws Section three, subsection E: Encouraging the more effective and expanded use of the higher frequency amateur radio frequency bands.

[amsat-bb] Re: About Shuttle Launch on Monday
The first launch I got to see was from roughly 150 miles away in Labelle, Florida, which is thirty miles east of Fort Myers. Was in my senior year of high school and was watching on the TV and the teacher said to go out and take a look. Some did and that was a sight to see the cloud of gases escaping and growing as it arced across the sky. My most memorable launch was a night launch when I was living in the Largo/Seminole area. Had a great site at Alt 19 (Seminole Blvd.) and Ulmerton Rd. next to the sheriff dept. Cloudless night. Looking over the mall that had just been built. Waiting and then seeing this miniature Sun start to come up, then the flames from the shuttle popped into view. At my distance, the flicker of the flame looked like someone had turned a disposable lighter upside down and moving it up. Tonight the local NBC affiliate had a report on how to view the ISS as it passes over head. James W8ISS ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.
