HRD with DXLab on sats
by jeff griffin 05 Jul '19

05 Jul '19

Has anyone on here use HRD with DXLab to work and log satellite contacts using the HRD to DXLab bridge? I'm trying to integrate an IC-9700 into my daily use sat setup, replacing SatPC32 and DXLab. I'm trying to get something that's more integrated then what I'm now using and the bridged HRD and DXLab look promising. Anyone doing this? Anyone interested in doing this? 73 Jeff kb2m

Do not forget if you would like your groups score included in the 2019 Field Day summary, your submission must be made by 11:59 PM, Monday, July 8, 2019. We are running a little behind last years submissions. I even have our club in with our one contact. You do not have to have a lot of contacts, any amount is respectable. It is the ooo's and ahhh's that those watching said when they saw a satellite contact being made. 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards AMSAT Board Member 2016-2020 ARRL Awards Field Checker (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0100z on Echolink - Conference *AMSAT* Also live streaming MP3 at http://www.amsatnet.com Podcast at http://www.amsatnet.com/podcast.xml or iTunes Latest satellite news on the ARRL Audio News http://www.arrl.org AMSAT on Twitter http://www.twitter.com/amsat

LO 94 and the solar eclipse
by Nico Janssen 04 Jul '19

04 Jul '19

On July 2 there will be a total solar eclipse that can be observed by the amateur satellite Lunar-OSCAR 94 (a.k.a. LongJiang 2 and DSLWP-B) from its elliptical orbit around the Moon. Attempts will be made to image the eclipse, where both the Moon and Earth should appear in the images. For details see these blog posts of Dani, EA4GPZ: https://destevez.net/2019/06/dslwp-b-and-the-solar-eclipse/ https://destevez.net/2019/06/imaging-times-for-dslwp-b-eclipse-observation/ Note that LO 94 is expected to crash onto the Moon's surface at the end of July, ending its mission. Until then you can still track LO 94 using GMAT and receive its 70 cm downlinks. 73, Nico PA0DLO

Yup, some passes can get pretty intense. But others can be pretty mellow. Don't give up yet.

Turned the corner on AISAT-1 APRS digipeats
by Scott 04 Jul '19

04 Jul '19

Greetings! Being smart would be cool, but sometimes it's just easier to be lucky. Since the launch of AISAT-1, I have really struggled to get digipeated thru that satellite. At best, I could get in a single digipeat but only at the exact moment of closest approach on a high pass. Armed with seeing that repeatedly, I thought doppler tracking the 145.825 FM uplink might help, but it did not. So tonight (4-July UTC), by pure coincidence, there was a high pass of AISAT-1 immediately following a pass of PSAT-2. Following Bob's (WB4APR) recommendation to use NARROW-FM on PSAT-2 (worked well), I thought "what the heck", I'll leave my radio set on NARROW-FM for the pass of AISAT-1 as well. I'll even doppler track the AISAT-1 uplink while I'm at it. Boom. Got digipeated left and right. Well before and after closest approach, I got digipeated. I didn't go crazy since I'm always so afraid of blocking out other people on a simplex satellite, but I hit it enough to see the night & day difference from what I'd been experiencing since deployment. If it's in the docs somewhere I missed it, but is sure seems to me that, like PSAT-2, AISAT-1 might very well be equipped with a NARROW-FM radio. It would be great to see if others find as much improvement as I did, so I hope some folks will try AISAT-1 using NARROW-FM on the 145.825 APRS digipeater. 73, -Scott, K4KDR

Lightsail2
by Hans BX2ABT 04 Jul '19

04 Jul '19

On Twitter I see successful decodes of telemetry and CW. I monitored a few passes, but either nothing heard, or I got a pulsating carrier with no modulation. I had passes both in sunlight and eclipsed. Are signals from Lightsail2 very weak and is my station too small to handle them? What can I expect? Who on this list has heard Lightsail2? 73 de Hans BX2ABT

APRS Satgate- Server and Port Information
by Nitin Muttin 04 Jul '19

04 Jul '19

All, I want to turn on the APRS satgate at my station. Installed UISS Satgate ver2.0 and trying to connect to satgate.aprsca.net using port 14850 but unable to connect. I have checked the AVG firewall in the PC and nothing is blocking this application. Also have tried port forwarding in the router but still unable to connect. I am able to ping satgate.aprsca.net Please share if there are other servers I could try for satgate. 73 Nitin [VU3TYG]
