Unsuccessful attempts in APRS through NO-84
by Rocco Labella 31 Oct '18

31 Oct '18

Hi, I've been trying to make APRS (AFSK 1k2 bps) contacts through NO-84 Satellite, and have been unsuccessful in all attempts using UISS and SOUNDMODEM. UISS configured with CQ & ARISS. Incoming packets from satellite decoding perfectly 100% but when I TX, satellite ignore me :( . I've monitored the outgoing audio and adjusted the TX level, with no results. Also I've monitored the outgoing audio and i heard a little audio tone difference between AGWPE and SOUNDMODEM. I tried also with terrestrial APRS digi and it work 80% good using SOUNDMODEM and 100% using AGWPE. Of course everything works perfectly using a hardware TNC. I'm coming to the conclusion that this must be a problem with my SOUNDMODEM settings, because if i use AGWPE, all work fine and NO-84 repeat my packet 100%, without changing anything on the transmitter (TS2000). Similar results through ISS APRS digi, (a little better) I would like to know if someone use a similar setup with good results. 73 Rocco IK8XLD www.qrz.com/db/ik8xld

by Patrick STODDARD (WD9EWK/VA7EWK) 30 Oct '18

Hi! I will have an AMSAT booth at the Oro Valley Amateur Radio Club's annual hamfest on Saturday, 10 November 2018 (the weekend after the AMSAT Symposium), in Marana, Arizona. The hamfest will be at the Marana Middle School, along the east I-10 frontage road southeast of exit 236, and approximately 25 miles northwest of downtown Tucson. Information about the hamfest is available in a PDF flyer: https://www.tucsonhamradio.org/images/2018%20Oro%20Valley%20Hamfest.pdf or from the club's web site: https://www.tucsonhamradio.org/ Along with the AMSAT booth, look for demonstrations of satellite operating from the hamfest. I will use my own WD9EWK call sign for the demonstrations. If you hear WD9EWK on a pass, please feel free to call and be a part of the demonstrations. The hamfest is in grid DM42jk, in Arizona's Pima County. I will use my @WD9EWK Twitter account to post updates from the hamfest, along with pictures. If you don't use Twitter, you can see these updates in a web browser at: http://twitter.com/WD9EWK Any QSOs made with WD9EWK during the hamfest will be uploaded to Logbook of the World after the hamfest. If you would like to receive a QSL card for a QSO during a demonstration, please e-mail me after the hamfest with the QSO details. If you are in my log, I'll be happy to mail a card your way. 73!

AO-85 question
by skristof＠etczone.com 30 Oct '18

30 Oct '18

Lately, I've been trying other FM satellites besides SO-50. I have made contacts on AO-92, but I can't get anything from AO-85. On AO-85 I can hear the voice ID of the satellite plain as day, but I never hear any other hams trying to make contacts and I can't seem to get into the satellite. My set up is two Baofeng handhelds and an Arrow antenna. This set up works fine on SO-50 and AO-92 so I know that it works. For AO-85 I'm using 435.170 for the uplink and 145.980 for the downlink. I have the uplink sending the 67.0 Hz tone. So, what am I missing? Constructive tips would be very much appreciated. Steve AI9IN

SSTV
by James Brown 30 Oct '18

30 Oct '18

In a attempt to decode the sstv signals, I managed to crash SAT 32. I now have everything working again but have missed the window for ISS SSTV.My station is SAT32PC with ERC rotor tracking. FT817 radio 1 as downlink and IC7100 as radio 2 uplink.I downloaded MMSSTV but could not decode the SSTV signal. I realized that there was no audio link to mmsstv. That's when SAT 32 crashed I had tried to change to configuration 2. I was unaware that there was a corrupted file in the software. What I am confused about is what sstv software should I use for ISS and how should it be configured to allow sat32 to do its job and decode the signal without conflicts? Jim KI6WJ
