Decoding the new AX.25 packet satellites
by Loren M. Lang 05 Dec '18

05 Dec '18

I have several raw IQ captures from last few days with the new satellites passing and am trying to decode the AX.25 packets from two of them. I'm using SDRSharp to reply them and pull the signals out using USB mode. I've already replayed them successfully and decoded both JY1-Sat and AO-95 using their respective software packages, but I'm having trouble figuring out ITASAT and MOVE-2. I'm using Virtual Audio Cable to loop back the audio and UZ7HO Sound modem in an attempt to decode them. For ITASAT, it's set to 1200 bps BPSK and for MOVE-2, I'm using the 9600 baud variant of BPSK Sound modem from his site. However, efforts have been fruitless to get it to resolve any packets. Any pointers for these satellites would be appreciated. 73s Loren K7IW

Requesting Skeds
by M Thomas 05 Dec '18

Is there a place to request/set skeds for WAS? I am sitting at 40 and obviously it gets harder from here. I found a place but there has only been one post in recent months. http://n8fq.org/sked/index.php?board=sat Thank you! Mark

Any update on AO-85?
by Hans BX2ABT 05 Dec '18

05 Dec '18

As per title. With my limited setup I am not able to decode any telemetry from AO-85 anymore. It still comes through the squelch on my rig+discone, but S/N ratio on my SDR+ArrowAlaska is about half what it normally was and with fading added there is no long enough sequence for decoding frames.

Re: [amsat-bb] FoxTelem Crashes coping Fox1 Cliff
by Alan 05 Dec '18

Frank, The BB list does not pass attachments or HTML, so you will need to provide a link. Fox-1Cliff was in Initial Mode, which is somewhat different from Safe Mode. No idea why this should cause a problem, however. It is now in Safe Mode, so you should have better luck. 73, Alan WA4SCA <-----Original Message----- <From: AMSAT-BB [mailto:[email protected]] On Behalf Of Frank <Sent: Tuesday, December 04, 2018 01:27 AM <To: AMSAT <amsat-bb(a)amsat.org> <Subject: [amsat-bb] FoxTelem Crashes coping Fox1 Cliff < <My FoxTelem crashes when coping DUV from Fox 1 Cliff.

Re: [amsat-bb] tracking Fox-1Cliff
by Dinesh Cyanam, AB3DC 05 Dec '18

Ashhar Farhan's bird is ExseedSat-1 and not Fox-1Cliff (AO-95). ExseedSat-1's downlink is on 145.900 MHz. You can use the Fox-1Cliff TLEs as both the sats were on the same pod during launch. As far as I know, no one has heard ExseedSat-1 beacon. 73, AB3DC Dinesh

tracking Fox-1Cliff
by Joe Puma 05 Dec '18

05 Dec '18

So Ashhar bird is called Fox-1Cliff correct? Can it be tracked in Orbitron? I suppose we need keplar data of the bird. The program has a file for cubesats but I don’t see the bird. I see other like funcube Ao-73. How are we all tracking Ashhars bird? I already have Foxtelem Joe Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10

Part of Spaceflight’s SSO-A: Smallsat Express launch, Fox-1Cliff was named after long time AMSAT supporter Cliff Buttschardt, K7RR (SK). In the 48 hours after launch, more than 110 amateur radio operators around the world have successfully received and submitted telemetry from the satellite. Following in our long tradition of naming amateur satellites, AMSAT hereby designates Fox-1Cliff as AMSAT-OSCAR 95 (AO-95). Thank you to those who have supported this mission with their time, talent, and financial support for the benefit of amateur radio operators worldwide. 73, Drew Glasbrenner, KO4MA AMSAT VP Operations / OSCAR Number Administrator [ANS thanks Drew Glasbrenner, KO4MA, AMSAT VP Operations / OSCAR Number Administrator for the above information] +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ For a limited time, new and rewewing AMSAT members will receive a free digital copy of "Getting Started with Amateur Satellites" Join or renew your AMSAT membership today at https://www.amsat.org/product-category/amsat-membership/ +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ /EX In addition to regular membership, AMSAT offers life memberships, and sustaining donors to AMSAT Project Funds, will be eligible to receive additional benefits.

TH-D72
by Stewart Morgan 04 Dec '18

04 Dec '18

Bob Bruninga reminded me that I was confusing the solution to two different problems. The squelch needs to be off in APRS and Packet modes in order for transmit (not receive) to function properly. Battery Saver mode should be off, otherwise APRS packet decoding is likely to suffer, and there are several mentions in the Kenwood documentation about this. Sorry for the mistake. Todd AL0I
