Bert, Just downloaded your program and uploaded my log. Seems to work OK, except that worked grids only show in bold print. I am not seeing the colored-coded by band boxes around each worked grid, as shown on your web page. I'm using an IBM Thinkpad T42 with Windows XP. Does the program show the total number of grids worked?

Re: Radio amateur calling protocol
by James Whitfield 27 Feb '08

27 Feb '08

I respect the opinions each of you have voiced. With some, I disagree. It seems to me that the problem is not that there are too many FM satellites, or perhaps as some have suggested that they exist at all, but rather there are not enough FM satellites, and the ones that exist have too few channels. The situation is similar to terrestrial repeaters: When too many users try to access the limited resource, more repeaters get built. When you run out of bandwidth, new repeaters get built on other bands. Usually accompanied by lots of grumbling about the cost of additional equipment, but it shifts the load from over-used spectrum to under-used spectrum. Newcomers adapt, frequently in spite of insults and other forms of "un-welcome". If a system does not attract enough newcomers activity will eventually die off, which is fortunate. When bad operating practice and bad manners get mixed with heavy use, the control elements slap access limiters on the systems, knowing that if they don't, regulating agencies will shut them down completely. If someone doesn't like the way a system is operated, he or she is entitled to form another group of like minded people to establish and run another system as they see fit within the same regulatory, financial, and technical environment. Sometimes they succeed, sometimes they don't. As far as I am personally concerned, I don't operate satellite. But given the opportunity to help a someone or some group put on a satellite demonstration to a Scout activity or a school, I would do so. I have the professional background to know how aerospace vehicles are made; I understand some of the physics of launch vehicles, orbital mechanics, and attitude control systems; and I have an archaic romantic notion that it is possible to have fun while you are learning something important. This thread would take a lot of editing before I could use it to encourage youth. James n5gui

Ham Log Grid Square Mapping Software
by Bert, VE2ZAZ 27 Feb '08

27 Feb '08

Hi Everyone, I've just finished developing WorkedGrids, a ham log grid square mapping software. It is a freeware and it runs under Windows. The program displays a map showing the amateur radio grid squares contacted and logged in using a third-party logging program. WorkedGrids uses colors to display information on a per-band basis. Up to four bands can be displayed concurrently on the map. For its input, the program reads the plain-text (ASCII) log files generated by most logging programs. This project was initiated because I could not find a logging program that provided the level of detail and mapping quality that I wanted. The software is directed towards the VHF andabove operators who collect grid squares for contesting or awardpurpose. It is designed to supplement a logging program and itreplaces the pen and paper technique. Please visit http://ve2zaz.net for more details. Your input is welcome!

Swan Island DXpedition will be QRV on the LEOs

I am pleased to report that HQ8R will be QRV on the satellites from Swan Island, grid EK87, from March 15-23. See http://www.hondurasdx.com/ I'll be taking my FT-817 and an Arrow antenna. Time permitting, I will also try to make a few contacts before and after the expedition from the Honduran mainland, EK55, EK65 and EK75. Weather permitting, we may also try to give out EK76 from the boat on the way to and from the island. 73, Bill NZ5N ____________________________________________________________________________________ Never miss a thing.

S-band patch.
by John Hackett 27 Feb '08

27 Feb '08

Mak, I can assure you the patch *IS* correct. The photo is taken from the rear, what you are seeing in the photo is the 'rear' of the reflector and the back end of the gold SMA connector. The radiator - (hidden by the larger reflector, in the photo) - is connected to the pip of the SMA connector and is mounted 3mm 'above' the reflector. The radiator is 'cut' for 2401Mhz and is made from silver plated brass sheet ... bas is the reflector. I think what may have fooled you is ... 1) Not realising you were looking at the rear of the patch. 2) The fact that my reflector is square, not round. The G3RUH design uses a round reflector, the K3OE uses square. As far as I can assertain there is no practical difference between the designs. 73 John. <la2qaa(a)amsat.org> 73 John.

Date: Wed, 27 Feb 2008 15:03:14 +0200 Hi John, I read your post but I am afraid that, your PATCH is not correct. Sorry if I am wrong, but due to non-clear photo I can see on the Left-UP part of photo ONLY the "drive element" of Patch (the square-piece with cut-corners ) without the "circular piece" behind of drive-element which acts as reflector. As I see also in your photo, the chassis-connector is mounted on this square piece and not to the circular reflector. If that is not my... illusion, that is not a correct Patch.

Working GO-32 with pb/pg
by Jeff Mock 27 Feb '08

27 Feb '08

I need a little help using pb/pg with GO-32 to upload/download files. I'm a linux guy, I have a linux machine running ax.25 software, talking to a TNC in KISS mode hooked up to my radio. Using the ax.25 utility 'listen -a' I can see GO-32 transmit packets when it passes overhead. I can sort of flail a bit with "pb" and it transmit some packets to GO-32 and even occasionally see GO-32 send back a packet with my callsign, so I'm pretty sure that the radio and low level link are at least sort-of working. Can someone give me a little guidance about how to use pb/pg to download a list of files, download a particular file, and upload a file. My aim is to upload a file, then download the file on a later pass, but I can't seem to figure it out on my own. thanks, jeff AD6EO

Radio amateur calling protocol

The answer to all of these ridiculous arguments on calling protocol is, of course, quit building FM voice 2 user satellites, like AO51. AO7, is what, 25 years old, none of those problems existed there, and still don't today. Blame those that encouraged and built AO51.... A lot of us voiced our disapproval at the time it was proposed, mostly for that very reason....and lost... Why was it built?? 73, Dave, WB6LLO dguimon1(a)san.rr.com Disagree: I learn....

Re: Radio amateur calling protocol (easy Sats)
by Bill Dzurilla 26 Feb '08

26 Feb '08

I share the frustration of everyone trying to work AO-51 and AO-27 on a busy weekend pass, but as a relative newbie I think the FM birds serve a purpose, in light of the huge cost difference between an FM only and an all-mode VHF/UHF rig. If it had not been so easy and inexpensive to work via AO-51, don't think I would have tried to work any sat. For me and probably many others, the good experiences on the FM sats led me to upgrade and work via AO-7 and VO-52, and I hope more like these are launched soon. Judging from the crowded state of the FM birds and the relative lack of activity on the sats with linear transponders, it seems that, for all their deficiencies, the FM birds are still a popular choice. Just need to keep teaching the need for brevity, clarity of speech, and proper power and antennas. 73, Bill NZ5N --- amsat-bb-request(a)amsat.org wrote: >>>The answer to all of these ridiculous arguments on calling protocol is, of course, quit building FM voice 2 user satellites, like AO51.
