IC-910H opinions sought
by Tim Tuck 15 Apr '07

15 Apr '07

Hi all, I'm thinking of retiring my Kenwood TS711/811 combination in favour of the Icom 910, so I can add 23cm and 9600baud i/o to my station. Reading some of the reviews on ehams have not entirely been favourable. I'd like to hear from any one who owns or has used the 910 before I part with my $s. regards Tim -- VK2XTT :: QF56if :: BMARC :: WIA :: AMSAT =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Scanned with Copfilter Version 0.84beta1 (ProxSMTP 1.6) AntiSpam: SpamAssassin 3.1.8 AntiVirus: ClamAV 0.90.1/3074 - Thu Apr 12 07:35:22 2007 by Markus Madlener @ http://www.copfilter.org =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Scanned with Copfilter Version 0.84beta1 (ProxSMTP 1.6) AntiVirus: ClamAV 0.90.1/3072 - Thu Apr 12 06:32:06 2007 by Markus Madlener @ http://www.copfilter.org

FO-29 QSO
by tjjapha＠earthlink.net 15 Apr '07

15 Apr '07

Domenico and All, It was a solid QSO with I8CVS on FO-29 from NYC (FN30). You were very strong; it was a perfect pass, even though it was a short window between us. I only heard 1 Eu stn on the next pass, which was a long pass with lots of time for N. Eu. We might be able to try again on Monday, but the wx forecast is bad just now. If that turns out to be true, it won't be possible to get the gear outside. We will have to wait until Monday morning here to see. I will send you an email then to let you know if it's possible. Maybe someone on the bb can tell me why I can send messages to the bb, but don't ever get others' messages as email. I must check the website to look at messages. Should I just unsubscribe and then subscribe again? Another question: I've had very little success on AO-7 using just 5 watts and 7el on the uplink, 3 el and a preamp on the downlink. Would it be a good investment to get a 20 watt amp for 70cm? Would it make a big difference? A 20 watt amp can be done portable, but not more than that. FO-29 is a great bird with very little activity, at least that I can hear. Being able to work I8CVS with a simple portable stn. is Exhibit A. 73, Tony, N2UN

Amateur as secondary payload
by Patrick McGrane 14 Apr '07

14 Apr '07

Greetings from Patrick N2OEQ What are some general comments regarding secondary amateur payloads on commercial satellites? I remember the old RS series and the new hamsat are secondary payloads. What are the costs involved versus building and launching individual autonomous satellites? Thanks for general history and general comments., pat

SATpc32 Question
by Kim - ac7yy 14 Apr '07

14 Apr '07

In need of some help: My current set up with my IC-910H is Nova v2.2b with unitrac 2000 v2.2.16 with the metal case (parallel interface) to the yaesu 5500 controller. Just bought SATpc32 from the AMSAT store. In the rotor setup, can I use the IF-100 setting to control the G-5500 thru the unitrac box? Or do I need a different way to control the G-5500?

FW: echo software change
by Patrick McGrane 14 Apr '07

14 Apr '07

------- Original Message ------- >From : Patrick McGrane[mailto:N2OEQ@aceweb.com] Sent : 4/13/2007 5:19:45 PM To : ao-51modes(a)amsat.org Cc : Subject : FW: echo software change Greetings Please post your preliminary results or observations of the new software changes on the amsat website. I am particularly interested in how you guys did with the power management aspects of the change. I was observing my tracking program a way back and noticed the signal improved a few seconds after the echo reached sunlight. Was this due to the software change or was I just observing a normal increase? I am very grateful to you folks for spending youre time on the new changes, thank you very much. 73 pat n2oeq

Oscar 51 packet baud rates
by Patrick McGrane 13 Apr '07

13 Apr '07

Greetings again from Patrick, N2OEQ I understand the ECHO BBS transmitter baud rate is 9600 or greater. Can someone operate the more common 1200 baud up to echo and will it appear as 1200 on the downlink and additionally, can this be accomplished by ground control? Thanks for replies, 73, pat
