K2P ISS packet contacts
by kb2m＠arrl.net 24 Sep '15

24 Sep '15

While discussing the Pope Francis event with Pete W2JV, we both thought it would be a good idea to also offer QSL cards for a packet contact with K2P via the ISS. As I'm at my antenna restricted summer home location at the Jersey shore for the rest of the week I would be able to concentrate on the packet contacts only. I will be active every day in the morning and maybe at night till the end of the event. I'm not going to do any portable SSB/FM ops from here as I just went through a shoulder replacement and the packet contacts will all I will be able to do. Pete W2JV is covering the Lion's share of SSB and FM voice contacts as K2P anyway. So I would be beaconing as K2P when available, all I would need is a 599 to which I would reply a 599 to, you would then be in the log as a K2P packet contact. Everyone have fun, and enjoy this historical event, God Bless.. 73 Jeff KB2M (K2P)

Hi Glenn, Thank you for the reply. Tried that hex file but unfortunately I got firmware 0.5 instead (shown on the LCD screen). 73, Sion, 9M2CQC <div>-------- Original message --------</div><div>From: Glenn Miller - AA5PK <aa5pk(a)suddenlink.net> </div><div>Date:09/25/2015 2:16 AM (GMT+08:00) </div><div>To: "Sion Chow Q.

(9W2QC) Sent: Thursday, September 24, 2015 11:31 AM To: amsat-bb(a)amsat.org Subject: [amsat-bb] LVB Tracker v0.9 Firmware Dear All, I have been an original LVB Tracker for many years running firmware 0.7. Recently I am having some problems with the serial communications and from the forums, I notice that firmware version 0.9 has resolved these issues. However, the link published (many of which are few years ago) to download this firmware at http://www.g6lvb.com/Articles/LVBTracker/LVBTrack.hex seems to be no longer valid. I have been trying to look around but failed to obtain a copy of the firmware version 0.9 .hex file. Would really appreciate any pointers of where I could obtain this new firmware. Thank you. 73, Sion Chow Q. C., 9M2CQC, WQ2C, 9V1QC, JG1XHM, ex: 9W2QC, AB3IO, WQ2C /HL1 /YB9 _______________________________________________ Sent via AMSAT-BB(a)amsat.org.

So I'm wondering if I'm operating properly. I'm using SATPC32 and letting it correct Doppler on both Uplink and Downlink. Is that correct?

[keps] CAS-3 Satellites Added to KEP Distribution
by Ray Hoad 24 Sep '15

24 Sep '15

The Chinese new Long March 6 (CZ-6) launched 14 objects into orbit on 2015-09-19 at 23:01:14.331 UTC. Of the these 6 have been identified so far, including the CZ-6 rocket body itself. (Thanks go to Nico Janssen, PA0DLO and those emailing on AMSAT-BB for their much appreciated efforts.) The satellites added are as follows: Object A - NORAD CAT ID 40899 Object B - NORAD CAT ID 40900 Object C - NORAD CAT ID 40901 Object D - NORAD CAT ID 40902 XW-2A - NORAD CAT ID 40903 (Object E) Object F - NORAD CAT ID 40904 XW-2F - NORAD CAT ID 40905 (Object G) XW-2C - NORAD CAT ID 40906 (Object H) Object J - NORAD CAT ID 40907 LILACSAT-2- NORAD CAT ID 40908 (Object K) XW-2E - NORAD CAT ID 40909 (Object L) Object M - NORAD CAT ID 40910 Object N - NORAD CAT ID 40911 Object P - NORAD CAT ID 40912 Note there are no OBJECT I or OBJECT O in the Spacetrack list. I assume, because of the similarity between I and 1 and between O and 0 (zero). The CZ-6 rocket body is NORAD CAT ID 40913 and has not been included in the KEP distribution. Ray Hoad WA5QGD

AMSAT website - menu
by Kevin M 24 Sep '15

24 Sep '15

Has the AMSAT website display gone squirrelly for anyone else? There is the initial pull down menu across the top, "AMSAT, Contact Us, blah, blah, blah Store"... But then there is 6 lines of other menu choices related to the AMSAT symposium and it covers up the pages content. It's like someone tried to add another menu but it's not displaying properly. Here I am using Firefox v41.0 for the coders. 73, Kevin N4UFO

XW-2E xpndr nil hrd
by Glenn Miller - AA5PK 24 Sep '15

24 Sep '15

Noted that the transponder on XW-2E was not heard on the 1415Z pass over western US. Its CW beacon was loud and clear. The XW-2F transponder and beacon were also loud and clear, but no one was on it but me. Glenn AA5PK DM91

Re: [amsat-bb] Fox Telemetry Decoder Software Version 1.0 Available for Download

Stefan, thanks for the feedback. I exchanged emails with Don earlier in the project. There is no way to read the Az El information from MacDoppler currently. I'm open to supporting it in the future if that feature becomes available. 73 Chris On Wed, Sep 23, 2015 at 6:13 PM, Stefan Wagener <wageners(a)gmail.com> wrote: > Hi Chris, > > Very nice tool.
