Improvements to the AMSAT Live OSCAR Satellite Status Page
by Joseph B. Fitzgerald 10 Sep '19

10 Sep '19

Thanks to the efforts of new member Ed, KN6DBC, improvements have been made to www.amsat.org/status<http://www.amsat.org/status>, specifically, some filtering of the "Your Callsign" field has been added in an effort to reject the occasional nonsense report. The entry must look like a callsign, for example it must have at least one digit, it must not end with a digit etc. As a bonus, the"Your Grid Square" field has been added. Separate entries are now preferred instead of workarounds like KM1P-FN42. AMSAT maintains this page to give a single global reference point for all users in the Amateur Satellite Service to show the most up-to-date status of all satellites as actually reported in real time by users around the world. Please help others and keep it current every time you access a bird. 73 de KM1P Joe

IC-706 with SatPC32
by jeff griffin 08 Sep '19

08 Sep '19

I'm working with an author of a logging program. What he is trying to do is integrate his logging program with SatPC32. One of his test radio's that he is using is an old first edition IC-706. He is having a problem getting his copy of SatPC32 to work with the IC-706. I'm pretty sure that the original 706 will work but honestly have never have done it myself, or seen it done. I can take a educated guess myself, but I would li9ke to hear from someone who actually has done this setup. Did anyone on one here do this? If so can they send me the SatPC32 radio setup info, and any pertinent 706 menu items that have to be set? Thanks in advance. 73 Jeff kb2m

Re: [amsat-bb] How to digipeat? (one digi call)
by Robert Bruninga 08 Sep '19

08 Sep '19

Slight correction: > UNPROTO CQ VIA <satellite-callsign> such as CQ VIA ARISS, RS0ISS, PSAT, LU7AA-1, etc. Can be confusing. The digipeater path <satellite callsign> should only have one callsign in it. Either the desired digipeating satellite's call, or the generic ARISS or APRSAT. There is no value to putting in more than one, it only makes the packet longer and will never get executed. * *Unless you are trying for a LIVE -dual HOP experiment. Then both satellites have to be in view and you must get the sequence in the right order as to which one is closer. Etc. The probability is so low, it is not worth burdening the 99.999% of your packets with two hops when 0.0001 might be successful. So far, in 4 years I have still not seen a single successful dual hop. Bob -----Original Message----- From: AMSAT-BB <amsat-bb-bounces(a)amsat.org> On Behalf Of JoAnne Maenpaa via AMSAT-BB Sent: Sunday, September 8, 2019 10:55 AM To: 'AMSAT-BB' <amsat-bb(a)amsat.org> Subject: Re: [amsat-bb] How to digipeat? I thought I'd toss out a few more hints to help folks trying to figure out how to get UISS to speak satellite packet. This is pretty much UISS specific detail. Make sure you have your station setup the way Scott and Hans have discussed. Setup your TNC with the MYCALL command. When you setup UISS the call sign you enter during setup will be your MYCALL parameter. Most of 145.825 MHz digipeater satellites use the AX.25 UI protocol You setup this protocol with the command: UNPROTO CQ VIA <satellite-callsign> such as CQ VIA ARISS, RS0ISS, PSAT, LU7AA-1, etc. You can enter these parameters in UISS in the top-left of the screen in the "To" and "Via" windows. Set "To:" as CQ and "Via" as the call sign of the satellite you are working. In the UISS 'Tx Text' window (the top text windows) enter: =Lat/Long-Message-to-digipeat -or- in my case near Chicago I use: =4211.29N/08827.08W-Greetings :-) You need the = and - in your message string. The dash displays your icon as the house on the map. To transmit your packet to the satellite click on the UISS Text/Data button and this should then trigger your transmitter. Folks use vari- ous combinations of PTT controls or VOX to trigger their transmitter - use whatever works for you. The shorter your message the better chance you have of getting digi- peated if lots of stations are causing packet collisions. Additional terrestrial packet routes such as WIDE1-1, WIDE2-1, etc. are not useful for space digipeating. Your target is the APRS satel- lite on 145.825 not the terrestrials on 144.390. The satellite digi- peats to us earthlings (and the SatGates) listening on 145.825. You aren't trying to tell every APRS station on 144.390 within hundreds of miles where you are driving. Adding all the WIDE strings also has the effect of making your packet longer, decreasing your success of getting digipeated on a busy pass. A lot of UISS setups document using AGWPE for your packet modem. This is a tried and true packet engine. Many of found that the UZ7HO soft- ware packet modem gives better performance especially when receiving. Your software packet modem will expect to receive the entire packet transmission with no errors - the correct checksum for it to be dis- played on your computer. Often you hear "good sounding" packets but if you aren't receiving the whole kahuna with correct checksum you won't get the message displayed. The same generally applies to the SatGate stations listening to the activity and gating it on to the web. The UISS program will require settings to be changed to operate with UZ7HO Soundmodem: In UISS top menu select Setup -> UISS -> LAN Click 'Enable LAN Mode' In LAN setup click on 'Enable LAN Mode' Host 127.0.0.1 AGWPort 8000 UISS may ask you to restart, go ahead and restart UISS. For normal operation start the UZ7HO Soundmodem first. Then start UISS. When both programs are running UISS will show it has connected with the Soundmodem: Connected to server 127.0.0.1 Port1 with Soundcard Ch: A; -- 73 de JoAnne K9JKM k9jkm(a)amsat.org _______________________________________________ Sent via AMSAT-BB(a)amsat.org.
