GO-32
by Vincenzo Mone 16 Jul '13

16 Jul '13

Hi to the list, anybody can confirm me if GO-32 is working? I am having a pass right now 13:15 UTC with a maximum elevation to 77 degrees. On the frequency 435.320 I can hear a strong signal that it seems to be at 9600 baud Because I can see the DCD led of my TNC flicking but it do not decode. The signal I hear is like an PSK signal. I am on FM mode. Please anybody can tell me if it is the GO-32 signal or it is a different signal that I hear? Thanks in advance. 73's de Enzo IK8OZV EasyLog 5 BetaTester EasyLog PDA BetaTester WinBollet BetaTester D.C.I.

Yes, CO-65's 1.2GHz is still operational. It is usually scheduled for operation at 9600bps GMSK of Up=1267.600 and Down=437.475 on Saturday and Sunday of every weekend. The ground station has been publicity on the web at the end of each month that either Digipeater or Message_Box of CO-65 is it's to be operational. I am open to the public at the beginning of each month such as the following image on my blog. http://www.ne.jp/asahi/hamradio/je9pel/30701c65.png http://wakky.asablo.jp/blog/ However, because the equipment of ground station so not good, it is not operational on schedule. Since the operation of Degipeater on 31 Mar 2013, the state of digipeater off has continued. Even now, it has been done by the recovery of the equipment of ground station will continue and there is the information that was digipeater ON inter- mittently at weekends recently. 11:28-11:40UTC, 31 Mar 2013, Ele 70 SE-E-N, 1267.603/437.475MHz 9600bps http://www.ne.jp/asahi/hamradio/je9pel/30331c65.png When Digipeater or Message_Box of CO-65 is turned on by the efforts of ground station, I will post the information immediately to the AMSAT-BB.

apogee prediction?
by Bob- W7LRD 16 Jul '13

16 Jul '13

Hello (again)...Is there a way (program) that one can predict when the apogee of a given satellite will favor a given grid square? Specifically FO29 varies from about 813 km to 1351km. One can potentially "stretch" the footprint when it is at apogee. 73 Bob W7LRD (sunny) Seattle

TNC-220 jumper info?
by Mike Nettles 15 Jul '13

15 Jul '13

I know its an old tnc but does anyone have info on the jumper settings they can scan and email to me? Or how the com port speed is set? If I can use it to free up one of my newer tnc's for another use that would be great. Would be nice to locate newer firmware if possible. I have a burner, just need the file. I ask here because most of the info I found on the net dealt with hams using this tnc for Satellites. Thanks and 73, Mike kb5wbh
